New trackers bring prairie dogs’ little-known underground life to light
- Researchers have deployed a new tracker that helps them monitor prairie dogs and track their movements underground.
- The tracker uses sensors, including accelerometers and magnetometers, and combines them with GPS technology to enable researchers to retrace the trajectories of the animals.
- Prairie dogs dig up complex burrow systems and spend most of their time underground, making their movements elusive.
- During initial trials, researchers were able to use the trackers to reconstruct the trajectories of prairie dogs while they were underground.

Nepal’s tiger conservation gets tech boost with AI-powered deer tracking
- Endangered tigers in Nepal heavily rely on spotted deer as their primary prey, making their conservation crucial.
- Researchers in Nepal are using vertical cameras and AI technology to track and profile individual spotted deer (Axis axis), similar to the methods used for tigers.
- However, the project has faced challenges, including low recapture rates and difficulty in distinguishing individual deer in the wild.

Barely making it: A conversation with ‘Eight Bears’ author Gloria Dickie
- Gloria Dickie is an award-winning journalist who has documented the state of the world’s eight remaining bear species in a compelling new book, “Eight Bears: Mythic Past and Imperiled Future.”
- Despite the conservation gains made by iconic bear species like the giant panda and the brown bear, most bear species remain at risk.
- In this podcast conversation, the author shares the context behind why some bear species, such as the Andean bear and the polar bear, which face climate-related threats, are much harder to protect.
- “It’s quite tricky for bears threatened by climate change and not just habitat loss,” she says on this episode.

Wildlife management platform EarthRanger goes mobile with new app
- Since it was launched in 2017, the EarthRanger software has helped protected-area managers, law enforcement agencies and wildlife conservationists to collect, visualize and track data from the field on a single platform.
- In a bid to be nimbler, the software has now gone mobile with an app that builds on the functions of the web-based platform; it also helps rangers use their phones as tracking devices.
- The app has already been used to track elephants as well as rangers in Kenya’s Maasai Mara, as well as to plan the response to an oil spill off the coast of the Philippines.

Expedition catches Amazon river dolphins to help save this iconic pink species
- In December, researchers gathered extensive data on a population of Amazon river dolphins in the Amanã Sustainable Development Reserve in the Brazilian state of Amazonas.
- They fitted some of the dolphins with radio transmitters to help map their preferred zones and identify priority regions for species protection.
- At the top of the food chain, the river dolphins play important roles as regulators of Amazonian river life and as environmental indicators for potential zoonoses.
- Hydroelectric dams, fishing, and contamination from mining pose the greatest threats to the species across its range.

Conservationists unite to tackle Latin America’s dog threat to wild cats
- Across Latin America, free-ranging and domestic dogs pose a threat to endangered wildlife, including several small cat species, conservationists say.
- Dogs entering forests or protected areas can disturb wildlife, directly prey upon them, decimate prey populations, and also spread disease.
- Last year, small-cat conservationists from Mexico to Chile united to vaccinate dogs in multiple countries to raise awareness of the problem and mitigate the threat.
- A second phase of this international campaign is planned this May, potentially focused on other threatened species.

In Calakmul, water troughs offer possible solution to human-wildlife conflict
- Beekeepers near the Calakmul Biosphere Reserve are working with conservationists to provide water troughs for wild animals in an effort to reduce conflicts with farmers and livestock.
- More than 70 species, including Baird’s tapir, jaguars (Panthera onca), ocelots (Leopardus pardalis) and coatis (genus Nasua), have used the troughs as climate change exacerbates water shortages in the biosphere during the dry season.
- Conservationists caution that such projects must be implemented carefully so as not to introduce pathogens into the wild or create “predator traps” where wild carnivores’ prey congregate around artificial water sources.

Forest management tool could help rein in rampant wildlife trade in Bangladesh
- The Bangladesh Forest Department has introduced a Spatial Monitoring and Reporting Tool (SMART) to help stop wildlife trafficking in several of the country’s protected forest areas.
- The pilot program follows the success of SMART technology used in the world’s largest mangrove forest, the Sundarbans, where a University of Calcutta study shows illegal logging and poaching have dropped significantly since the introduction of the tool.
- According to the Wildlife Conservation Society, major gaps in information about wildlife trade chains hamper the government’s ability to stop wildlife crimes.
- Experts say SMART patrolling should be introduced in protected forest areas across the country.

Should more wildlife trade be legal and regulated? It’s complicated, say scientists
- As the global international trade treaty approaches its half century anniversary, some scientists say it needs an overhaul to make its structures fit for 21st century.
- Allowing for legal, regulated trade could be better than banning it for many species, they argue, referring to successful case studies where local communities were involved in sustainable trade.
- But some conservationists are worried that changing the way CITES operates will be bad news for endangered wildlife and point out it has been a significant factor in the survival of species such as elephants and tigers.

In Gabon, camera-trap developers find the ideal proving ground for their craft
- Rich in forests and biodiversity, the Central African country of Gabon has long proved a fruitful testing ground for camera-trap technology.
- Snapshots of species once thought extinct in the country, such as lions, have helped inform conservation policy, including the establishment of national parks and protection of vast swaths of forest.
- The wealth of data generated means there are large data sets from various projects that researchers just don’t have the resources or time to sift through — which is why Gabon has also become a testing ground for artificial intelligence tools to aid in that task.
- Key limitations remain the cost of camera traps and the fact that many forms of data capture and analysis simply can’t be done by camera traps or AI, and still require human involvement.

Where do the guitarfish go? Scientists and fishers team up to find out
- In late March and early April of this year, a team of researchers and local fishers caught, sampled and released more than 50 sharks and rays in the Bijagós Archipelago of Guinea-Bissau, including several threatened species.
- A first for conservation, researchers tagged members of a critically endangered ray species, the blackchin guitarfish (Glaucostegus cemiculus), with satellite transmitters.
- Team leader Guido Leurs says the research will provide crucial information for policymakers to better protect sharks and rays in Guinea-Bissau.
- Fisheries management within the archipelago, which spans 12,950 square kilometers (5,000 square miles) and 88 islands, is a challenge for the West African nation.

Data from droppings: Researchers draw up a genetic ID map for chimps
- As part of a broader project studying the cultural and genetic diversity of chimpanzees across Africa, researchers have used fecal samples from 48 sites across the continent to create a genetic identity data set of chimpanzees across the species’ range.
- The data set supports the division of chimpanzees into the four currently recognized subspecies, as well as shedding light on historic gene flow between subspecies and between chimpanzees and bonobos.
- The data set can help conservationists determine the genetic origin of chimpanzees confiscated from the illegal wildlife trade and identify poaching hotspots, researchers say.

Smart Parks, the Dutch technologists tackling poaching with technology
- Smart Parks is a Netherlands-based organization deploying high tech and an R&D-focused approach to finding technological solutions to conservation problems.
- The organization is best-known for using LoRa (long range) wireless technology to create networks of connected sensors and devices within conservation areas.
- These are designed to help anti-poaching teams through access to real-time data such as animal locations, vehicle movements, and fence voltages, among other parameters.
- Working primarily in Africa, Smart Parks’ next phase of development is to add more sensors to tracking collars to collect additional data such as animal sounds and movement data, and then use machine learning to gain additional insights for research.

With sea ice melting, glacial ice could be a lifeline for polar bears
- Scientists recently discovered a new subpopulation of polar bears living in southeast Greenland that is genetically and behaviorally distinct.
- While most polar bears depend upon sea ice for survival, the polar bears in Southeast Greenland use pieces of glacial ice as habitat and hunting platforms.
- Large numbers of polar bears are expected to decline as climate change accelerates, but small populations may persist in places like this, where the pace of melting is expected to be slower, experts say.

A helping hand for red-footed tortoises making a comeback in Argentina
- Conservationists are releasing red-footed tortoises back into El Impenetrable National Park in Argentina’s Chaco province, in an effort to reintroduce the species to the region.
- The species is so rarely seen in the Gran Chaco region of Argentina that it’s believed to be locally extinct there.
- Red-footed tortoises are under threat due to the illegal pet trade, habitat destruction, and hunting for meat consumption.
- The species is the latest being reintroduced by Rewilding Argentina, which has already brought back species like jaguars and marsh deer to El Impenetrable.

As tiger numbers in Nepal and India grow, their freedom to roam shrinks
- Nepal is one of the few countries on track to double its tiger population this year from a 2010 baseline.
- But a growing sense of “animal nationalism” threatens to mar this success, with local media playing up the tigers’ travels across the border into India.
- The big cats, which don’t recognize political boundaries, have always roamed a wide range in this region, yet even this behavior is under threat as key corridors are restricted or cut off entirely by infrastructure projects by both countries.
- Conservationists have called for keeping nationalism out of planning and implementation of conservation efforts, for the sake of this iconic species.

Himalayan musk deer talk to each other through poop, but poachers are also listening
- A new study has indicated to scientists what poachers in Nepal may have long known: that Himalayan musk deer use their defecation sites as a sort of message board to communicate with one another.
- The endangered species is typically solitary and has limited vocalization, but its varied behavior at latrine sites — defecating, browsing, sniffing, scrapping and covering, and ignoring — appear to show efforts to convey messages to the other deer using the sites.
- Poachers may have long known about this behavior, and accordingly set their snares near latrine sites, where they target the male deer for their scent glands — prized for making perfume and traditional medicine.
- The authors of the new study say this finding could help improve conservation activities, including ensuring mating success for captive-breeding efforts.

Wildlife death toll from 2020 Pantanal fires tops 17 million, study finds
- A new study has found that nearly 17 million animals died in the Pantanal fires in 2020.
- The researchers came to this estimate by conducting distance sampling surveys, walking tracts of the Pantanal shortly after the fires and counting the number of dead vertebrates they encountered.
- However, the researchers say this is likely to be an underestimate since animals may have died underground or may have died later from burn injuries.
- The 2020 fires burned 4.5 million hectares (11 million acres) of the Pantanal, which is about 30% of the entire biome.

Translocation brings white rhinos to Rwanda, a new land for an old species
- On Nov. 29, 30 white rhinos were introduced to Akagera National Park in Rwanda from a private game reserve in South Africa.
- The relocation is aimed at establishing the species in a new range state and ensuring its survival into the future.
- Akagera National Park has not had a single high-value animal poached for the past 11 years, and has become a sanctuary for other translocated species such as lions and black rhinos, according to the NGO African Parks, which helps to manage Akagera.
- White rhinos are considered a near threatened species that under continual threat from poaching incidents.

DNA assessment confirms Gabon as last stronghold of forest elephants
- A new survey has found that there are more than 95,000 critically endangered forest elephants in Gabon, which is considered to be the last remaining stronghold for the species.
- The researchers came to this estimate after collecting elephant dung samples across Gabon and analyzing each sample’s genetic material.
- The survey found that forest elephants were present in about 90% of the country, in both protected and nonprotected areas.
- Forest elephants have been heavily poached in Gabon in the last couple of decades, with 25,000 killed in Gabon’s Minkébé National Park alone between 2004 and 2014.

Hungry like the maned wolf pup: Clips give rare glimpse of elusive canine
- New camera-trap clips show three maned wolf pups nursing and eating regurgitated food from their mother.
- This is the first time this behavior has been observed and documented in wild maned wolves, experts say.
- Wild maned wolves have recently recolonized Iberá National Park in Argentina, thanks to conservation efforts.

Tracking white-bellied pangolins in Nigeria, the new global trafficking hub
- Nigeria has in recent years become a major transit point for the illegal trade in pangolins, the scaly anteater known for being the most trafficked mammal in the world.
- With the four Asian pangolin species increasingly scarce, traffickers have made Nigeria their hub for collecting scales and meat from the four African species and shipping them to East Asia.
- In Cross River National Park, home to the elusive white-bellied pangolin, researcher Charles Emogor is working to both study the species and work with communities to end the poaching.
- “Until our government faces up to the fact that we’ve become a staging ground for the pangolin trade, I fear we’re only going to see more cross-border smuggling of scales, and more pangolin flesh for sale in wild meat markets,” he says.

The cat is back: Wild Amur tigers rebound in China, thanks to govt policies
- Camera trap footage taken between 2013 and 2018 revealed that about 55 endangered Amur tigers are now living in northeastern China.
- Experts say the tigers’ reemergence in the region is largely due to Chinese national policies favoring environmental stewardship, including the Natural Forest Protection Project and the establishment of several reserves.
- According to a recent paper, northeastern China could actually support about 310 tigers, including 119 breeding females, if further efforts are taken to minimize human pressures and ecological corridors are established between tiger habitats.
- While tiger numbers are growing in China, the species continues to face threats of poaching, habitat loss and fragmentation, and human-wildlife conflict.

Find my elephant: The conservation apps revolutionizing how rangers work
- Conservationists around the world have increasingly turned to technology to adapt and respond to rising challenges in protected areas.
- One example is EarthRanger, which collects and integrates information from several remote sensors and allows users to visualize data under one platform.
- The software solution helps conservationists with security, ecological management, and human-wildlife conflict, by streamlining conservation data into a system that helps them make informed decisions rapidly.
- While promising, the technology has encountered teething problems: lack of internet infrastructure, the need for an extensive network of sensors, and high data literacy to use the technology.

African wild dogs return to southern Malawi for the first time in 20 years
- Fourteen endangered African wild dogs were recently translocated to Malawi in an attempt to reestablish populations in Liwonde National Park and Majete Wildlife Reserve.
- There are currently only about 6,600 African wild dogs, including 700 breeding pairs, left on the African continent.
- Experts say the success of the translocation will hinge upon whether the dogs reproduce and form a larger population, and also if they manage to stay away from danger if they wander outside the reserve.

For Atlantic sea turtles, Sargasso Sea is home during the ‘lost years’
- In a new study, researchers tracked the movements of young green turtles and found that they navigated toward the Sargasso Sea, rather than drifting passively along the currents in the North Atlantic Ocean.
- While there have been theories and anecdotal evidence that turtle hatchlings travel to the Sargasso Sea and spend their “lost years” in the region, this is the first study that uses satellite tracking to confirm that green turtles are indeed going there.
- A previous study by the same group of researchers also tracked the movements of loggerhead turtles into the Sargasso Sea, although their journeys were found to be more nuanced.
- Experts say the study draws attention to the importance of protecting the Sargasso Sea and tackling issues such as plastic pollution.

Female putty-nosed monkeys get their males to run defense against predators
- A new study found that female putty-nosed monkeys use alarm calls to recruit males to be their “hired guns” when a predator is detected, only stopping their vocalizations once males have been enlisted to ward off the threat.
- Recruited males will vocalize their participation with a “pyow” call, which may aid their reproductive chances in the future, according to the study.
- The researchers also observed that male putty-nosed monkeys emitted a newly described “kek” call when responding to a simulation of a leopard moving along the forest floor.
- The researchers say that this study, as well as related studies, can aid conservation efforts for the putty-nosed monkey, a near-threatened species, and broaden our understanding of communicative and cognitive capacities of non-human primate species.

Electronic ears listen to poachers in a key Central American jaguar habitat
- The international NGO Panthera has been using acoustical monitoring systems to support their anti-poaching patrols in Guatemala and Honduras since 2017.
- The acoustical recorders can pick up gunshots, conversations and wildlife sounds, and help rangers plan their patrols to be more effective in combating illegal activities.
- Panthera is particularly concerned about protecting the jaguar, which is threatened by poaching, wildlife trafficking and habitat loss in this region.

Big cat comeback: Jaguars prowl Argentina’s Iberá Wetlands after 70 years
- Conservationists recently released three jaguars — a mother and two cubs — into Gran Iberá Park in northeastern Argentina’s Corrientes province in an attempt to rewild the local ecosystem.
- Jaguars haven’t been present in the Iberá Wetlands for the past 70 years, after hunting and habitat loss drove them to local extinction.
- The ultimate goal of the jaguar reintroduction program is to reestablish a healthy, genetically diverse population of jaguars in Gran Iberá Park, which has the capacity to hold about 100 jaguars, according to conservationists.

Cat fight: Jaguar ambushes ocelot in rare camera trap footage
- Camera trap footage revealed a jaguar killing an ocelot at a waterhole in the Maya Biosphere Reserve of northern Guatemala.
- While this kind of killing event is considered rare, it can occur when two predator species are competing with each other over resources such as water.
- Prolonged drought, compounded by climate change, may have influenced this event by making water scarcer than usual, according to the researchers who documented the incident.
- However, other experts say that climate change wouldn’t have necessarily influenced this behavior since ocelots and jaguars have lived together for a long time.

Whale of a find: Scientists spot beaked whale believed to be a new species
- Scientists on board a Sea Shepherd vessel say they found a new species of beaked whale near the San Benito Islands off Mexico’s Pacific coast.
- The species differs visually and acoustically from other beaked whales species, according to the researchers.
- The team took photographs, video recordings and acoustical recordings of the species, and also performed environmental genetic sampling to help confirm the existence of a new species.
- However, other experts say that detailed descriptions of the animals’ physical features and skeletal structure are needed before a new species can be accurately identified.

The Amazon’s short-eared dog was thought to be a scavenger. Now there’s video
- After installing a camera trap near a dead armadillo, a biologist unexpectedly recorded video of the elusive short-eared dog (Atelocynus microtis) scavenging on the carcass, and subsequently published a field report about the incident.
- While there was previous anecdotal evidence that short-eared dogs scavenge, this field report provides the first published documentation of this behavior, according to its author.
- In general, very little is known about the short-eared dog, including information about the species’ biology and ecology, although researchers are working to fill these gaps.

A warming Arctic is changing animal migrations, decades of tracking shows
- The newly launched Arctic Animal Movement Archive (AAMA) includes 28 years of terrestrial and marine animal tracking studies on more than 96 species across the Arctic, Arctic marine, and subarctic (including boreal forests and taiga).
- “The Arctic is undergoing some of the most rapid climate change on the planet,” one author said. The resulting warmer winters, earlier spring snowmelt, and the loss of ice are affecting animal movement.
- Researchers conducted their first case studies using the AAMA and found large-scale patterns in the way caribou, moose, wolves, golden eagles, and bears are responding to climate change. The findings were published in the journal Science.
- In their analyses, researchers found that the northernmost herds of caribou have begun giving birth earlier in the spring. After mild winters, immature golden eagles arrived earlier in the spring to breeding grounds than adult birds.

Video: Vets hail ‘victory’ as jaguar burned in Pantanal fires returns to wild
- This year, fires in the Pantanal, the world’s largest wetland region, burned through about 4.1 million hectares (10.1 million acres), which constitutes about 28% of the region.
- A 3-year-old jaguar caught in the fires suffered third-degree burns on all four of his paws as he ran across burning peat.
- In September, the jaguar was rescued by a group of veterinarians and delivered to a clinic that helped treat his wounds.
- A month later, rains had extinguished most of the fires, and the jaguar was released in the same spot from which he was rescued.

The other Corona: Rescued pangolin is a rehabilitation success story
- In February, a 2-year-old female pangolin named Cory was rescued in a sting operation led by the African Pangolin Working Group.
- Cory was in poor condition immediately after her rescue, but she responded well to rehabilitation, likely due to her young age.
- She was released on Manyoni Reserve in KwaZulu-Natal province, South Africa, where pangolins have been ecologically extinct for the past 30 to 40 years.

Sea turtles often lose their way, but always reach their destination
- A new study found that green sea turtles rely on a “crude map” to navigate the ocean, often going several hundred kilometers off course before successfully arriving at their destination.
- Using GPS tracking devices, the research team tracked the migrations of female green turtles from nesting grounds on Diego Garcia Island in the Indian Ocean to foraging grounds on isolated oceanic islands.
- Green turtles demonstrate a particularly high fidelity to foraging grounds, which made them an ideal species to study.
- The researchers say they hope their findings will help inform conservation efforts to protect green turtles, which are an endangered species.

‘It’s a success’: Pangolins return to a region where they were once extinct
- Temminck’s pangolins have been “ecologically extinct” in South Africa’s KwaZulu-Natal province Africa for the past 30 or 40 years, but a new program managed by the African Pangolin Working Group is reintroducing the scaly anteaters back into this region.
- Pangolins rescued from the illegal wildlife trade tend to be physically ill and mentally stressed, and need to go through a lengthy rehabilitation process before they can be released.
- Instead of simply releasing pangolins back into the wild, the African Pangolin Working Group puts the animals through a “soft release” program, and continues to closely monitor them through GPS satellite and VHF radio tracking tags.
- In 2019, seven pangolins were released at Phinda Private Game Reserve in KwaZulu-Natal; two died of natural causes, but the remaining five are doing well.

Baby humpback whales bulk up in Hawaii ahead of migration [VIDEO]
- New video reveals baby humpback whales nursing in Hawaii, a sight rarely seen by humans.
- A team of researchers used non-invasive suction cups to outfit seven baby humpback whales with special tags for recording data on nursing as well as other whale behaviors.
- During their time in Hawaii, the whale calves must drink enough milk to fatten up for a one to two-month migration back to Alaska.
- The researchers hope to understand the needs of mother whales and their calves during their time in the tropical breeding grounds and for their long migration.

Does Lucius Fox know? Tiny tech tracks bats (and more)
- A newly developed tracking device that fits like a tiny backpack allows scientists to monitor small animals.
- The wireless biologging network (WBN) device allows for proximity sensing, high-resolution tracking, and long-range remote data download all at the same time.
- The capability of the WBN device to track associations is providing scientists with new insights into animal behavior and conservation solutions.
- The device, weighing just 2 grams (0.07 ounces), is designed to be glued onto the back of animals like bats and eventually fall off after a few weeks.

Mug shots and public pics join the dots of whale sharks’ Southeast Asian trips
- A study blending old and new techniques has recorded young whale sharks returning to the same spot in the Philippines after visiting Malaysia and Indonesia.
- Scientists recorded the second-biggest aggregation of whale sharks in the Philippines in Honda Bay in the province of Palawan.
- Compared to other whale shark groups in the Philippines, the one in Honda Bay is made up mostly of juvenile males that feed on small fish and krill.
- The discovery underscores the need for stronger collaboration between the Philippines, Malaysia and Indonesia, all part of the Sulu-Sulawesi Seascape Project under the Coral Triangle Initiative.

Coronavirus outbreak may spur Southeast Asian action on wildlife trafficking
- Illegal wildlife trafficking remains a perennial problem in Southeast Asia, but with the ongoing spread of the new coronavirus, there’s added impetus for governments in the region to clamp down on the illicit trade.
- The coronavirus disease, or COVID-19, has infected more than 90,000 people worldwide and killed more than 3,000, according to the World Health Organization.
- Initial findings, though not conclusive, have linked the virus to pangolins, the most trafficked mammal on Earth and one of the mainstays of the illegal wildlife trade in Southeast Asia that feeds the Chinese market.
- Despite having a regional cooperation framework designed to curb wildlife trafficking, Southeast Asian governments have yet to agree on and finance a sustainability plan to strengthen efforts against the illegal trade.

For tiger moms, the work-life balance struggle is real, study finds
- For the first time ever, scientists were able to document the behavior of a GPS-collared Amur tiger in the wild for the four months before and four months after the birth of her cubs.
- The study, published in the journal Mammal Research, reveals that the new tiger mom made time for her cubs by abandoning defense of her territory, traveling more rapidly from kills, making fewer but larger kills, and resting less.
- The Amur tiger (Panthera tigris altaica), sometimes referred to as the Siberian tiger, is currently listed as an endangered species on the IUCN Red List.
- Poaching is now the biggest threat to the wild Amur tigers, as tiger parts continue to be in high demand throughout Asia for use as ornaments, in traditional medicine, and as a status symbol.

Protected areas best conserve mammalian diversity when connected with corridors, biologged weasels show
- For protected area (PA) networks to be an effective conservation tool, they should be well-connected to allow species movement through unprotected landscapes, but questions remain on what configuration of natural features can best facilitate animal movement.
- A recent study compared three theories of animal movement (structurally intact corridors, least-cost paths, and stepping stones) by analyzing the fine-scale movements of GPS-tagged fishers, a member of the weasel family. They found the tagged fishers consistently moved along structurally intact, natural corridors across a PA network.
- With the Aichi 2020 Biodiversity Targets in mind, the authors highlight that simply increasing the number of protected areas alone may not achieve the objectives of the protected area network amidst an increasingly fragmented landscape; the conservation of natural corridors between PAs may be equally important, something for future planners to consider.

Reducing human-elephant encounters with calls, texts, and digital signs
- The Hassan district of Karnataka, India has been a hotbed of human-elephant encounters for years and a challenge for forest authorities, who have been translocating crop-raiding elephants for decades.
- Researchers have replicated an elephant alert system that combines signs, voice calls, and text messaging used in the elephant corridors of neighboring Tamil Nadu’s Valparai region to reduce negative interactions between people and elephants in Hassan.
- Using familiar technologies, the new system has reduced annual human fatalities in the region from several to nearly zero.

As animal tagging goes cutting-edge, ethical questions abound
- An increasing number of animal tracking devices, known as biologgers, also measure environmental variables such as sound, temperature, and ocean salinity.
- Data from biologgers complement information on an animal’s movements and help scientists understand its environment, but can have measurable effects on the animal’s behavior or reproduction.
- As the field of biologging rapidly grows, scientists are trying to develop ethical frameworks for applying devices to wild animals.

A ‘FitBit for squid’ could help track the ocean’s squishier species
- The ITAG, a neutrally buoyant sensor device for soft-bodied invertebrates, is currently in development through joint research at Woods Hole Oceanographic Institute and Monterey Bay Aquatic Research Institute.
- The device has shown success in tracking animals such as squid and jellyfish as they respond to environmental changes.
- The casing is 3D printable, and the electronics array will be open-sourced, so scientists may quickly develop tracking devices for other marine invertebrates previously difficult to monitor.
- The current ITAG versions are smaller and more easily retrievable than a 2015 prototype, but researchers are still working to bring the size down and the retrieval rates up.

10 ways conservation tech shifted into auto in 2018
- Conservation scientists are increasingly automating their research and monitoring work, to make their analyses faster and more consistent; moreover, machine learning algorithms and neural networks constantly improve as they process additional information.
- Pattern recognition detects species by their appearance or calls; quantifies changes in vegetation from satellite images; tracks movements by fishing ships on the high seas.
- Automating even part of the analysis process, such as eliminating images with no animals, substantially reduces processing time and cost.
- Automated recognition of target objects requires a reference database: the species and objects used to create the algorithm determine the universe of species and objects the system will then be able to identify.

For the birds: Innovations enable tracking of even small flying animals
- Advances in satellite communications have revolutionized wildlife telemetry, yet tracking the movements of small animals, especially ones that fly, and marine species, which rarely break the ocean’s surface, has remained a challenge.
- In a November 20th virtual meetup on next-generation wildlife tracking, three speakers introduced developments that have broadened telemetry’s reach to new species and new types of data being collected.
- Recent innovations — including the ICARUS tracking system, hybridization of communications platforms, and miniaturization of sensors — are producing tiny solar-powered tracking tags and tags carrying various environmental sensors that function within private networks flexible enough to use the most efficient of several communications technologies available at a given site.

Filling in the gaps: Managing endangered species on the high seas
- Information about how marine animals move through the oceans has become vitally important as efforts progress to create a global plan for securing sustainable fish stocks in the high seas. Researchers are integrating new technologies and applying new approaches to data sets to find answers.
- A recent examination of the long-term Tagging of Pelagic Predators (TOPP) data set has mapped the travel patterns of marine predators — certain whale, turtle, tuna, shark, and seabird species — through their life cycles.
- The study showed that many of these predators spend over half their time on the high seas, supporting the need for global strategies to protect and monitor the high seas. Vessel identification systems paired with several emerging satellite technologies can help.

Tiny tags and a broad research network help track small animal movements
- Despite great advances in radio-telemetry technology, tracking small animals still presents challenges due to the weight of tracking equipment.
- The Motus Wildlife Tracking System uses nano-tags as light as 0.2 grams to track even small birds and insects.
- Based on a collaborative deployment of automated telemetry receivers, Motus can track animals over a broad geographical region to help answer fundamental questions about animal movements, leading to insights that can help protect migratory species as they traverse the landscape.

Animated animals: can games engage an audience with a conservation message?
- Video games that incorporate new data visualization technologies offer an alternative channel to communicate the ecology and the plight of wildlife to an otherwise untapped audience.
- An online game called Safari Central will combine real tracking data from animals in the wild with augmented reality, creating virtual avatars of these namesakes.
- Though still unproven, games also offer an unconventional business model to support wildlife conservation programs through small in-game purchases by a potentially huge audience.

Location, location, location goes high-tech: Facts and FAQs about satellite-based wildlife tracking
- Satellite-based tracking tags, including ARGOS and GPS systems, collect and communicate animal locations and in some cases, acceleration and physiological data—straight to your computer, 24/7.
- ARGOS satellites use their relative position and the Doppler shift to estimate a tag’s location, which they relay back to Earth. GPS tags receive position information from multiple satellites and either store it or resend it via another communications network.
- Satellite-based tags weigh more, cost more, and demand more power than VHF radio tags. Nevertheless, they provide automated collection of thousands of point locations of an animal, which helps researchers to more precisely define home ranges, migration routes, and the relationships of these patterns to landscape features.

Howler monkeys booming in Belize sanctuary 25 years after translocation
- Disease, hurricanes and hunting wiped out the native howler monkeys living in the Cockscomb Basin by the 1970s.
- Between 1992 and 1994, 62 black howler monkeys (Alouatta pigra) were relocated from a nearby reserve.
- After surveying the Cockscomb Basin Wildlife Sanctuary in March and April, scientists figure there are at least 170 howler monkeys – and perhaps many more – living all over the 51,800-hectare (128,000-acre) preserve.

The week in environmental news – April 22, 2016
- A new approach to mosquito control involving the release of 3 million genetically modified mosquitoes has not been well received.
- Representatives from over 170 countries gathered at the UN headquarters in New York this week to sign the Paris climate agreement.
- Thousands of fish, including rare species that live far off the shore are washing up on beaches along the central coast of Vietnam.

A sex change phenomenon in fish suggests there is something in the water
- A new study published in Ecotoxicology and Environmental Safety finds that male fish are turning into females – a phenomenon known as intersex – due to chemical pollution, specifically estrogenic endocrine disrupting chemicals or EEDCs.
- Researchers have found evidence of intersex in 85 percent of smallmouth bass and 27 percent of largemouth bass tested on 19 National Wildlife Refuges from Maine to Virginia.
- The varied and numerous sources of EEDCs make them difficult to track. Single-point sources, such as large buildings with obvious effluent pipes like waste water treatment plants and paper pulp mills, are of major concern.

Scientists try hair traps to track tropical carnivores
- Since 1990, the use of hair traps has been rapidly expanding in wildlife biology, but mainly in cooler climates.
- By collecting hair samples, scientists can non-invasively collect DNA samples of wild animal populations to learn about genetic diversity and determine their habitat ranges.
- Three past studies successfully used hair traps in the tropics. Two monitored several species of carnivores in Mexico, and one, as yet unpublished, monitored dingoes in Australia.

Scientists launch global shark and ray census
- Scientists estimate that each year, up to 73 million sharks have their fins sliced off to make shark fin soup — a Chinese delicacy.
- A growing appetite for shark fins and meat is considered the leading cause of sharply declining shark populations.
- An international initiative that will assess the health of populations of sharks and rays in 400 different locations over a period of three years has been launched.

The wild side of Peru gets an imaging makeover
- An exclusive Mongabay interview with University of Washington researcher Samantha Zwicker.
- Zwicker’s game camera research is documenting the responses of Peruvian cats and other mammals to road network expansion, selective timber logging, and the clearing of forests for cacao plantations.
- Such baseline research can offer important data to better understand wildlife dispersal and gene flow throughout the region, and for delineating future protected areas and wildlife corridors, along with other conservation goals.

Scientists turn to DNA from Sumatran elephant dung to aid conservation
- With only roughly 2,800 individuals, the Sumatran elephant (Elephas maximus sumatranus) is critically endangered.
- Population data for Sumatran elephants has been notoriously difficult to gather due to the rarity of sightings and the small size and isolation of the areas in which the elephants live, complicating conservation efforts.
- A new study based on an unusual technique of analyzing DNA in elephant dung provides an assessment of the largest known elephant population in central Sumatra, Indonesia.

Identifying and counting the wild orangutans of Borneo
- In a recent study, game camera traps were used to identify and estimate the numbers of orangutans in the Wehea Forest of East Kalimantan, Borneo.
- Prior to the study, the most reliable method for estimating orangutan population numbers was to count the number of orangutan nests in a certain area.
- Given the current dire conservation situation for orangutans, the study team believes that camera trapping is an important step toward obtaining a more accurate understanding of the number of orangutans that still exist.

Rare spotted leopards sighted on Malaysian Peninsula
- Previous research determined that only melanistic black leopards likely lived in the forested regions of Southeast Asia.
- The discovery of two spotted leopards may have shed some doubt on the previous hypothesis that the forested regions of Southeast Asia was the only place in the world where an entire population of animals is almost completely composed of the melanistic form.
- This new discovery points to the need for the conservation of the Ulu Muda Forest where these regionally rare spotted leopards were found, especially in light of the area’s escalating environmental pressures.

Advanced Animal Tracker Helps To Explain Big Cat’s Hunting Strategy
- Real-time monitoring and instantaneous energetics are giving scientists access to large amounts of in-situ data on big cats
- SMART collar is calibrated to understand how much energy is expended by a puma during all daily activities based on accelerometer data.
- Pumas spend large amounts of energy on cryptic behaviors (e.g. searching for prey) and spend 2.3 times more energy hunting overall than was previously predicted by ex-situ models.
