A new study suggests that strategically removing sections of fencing in southern Africa could make both livestock and wildlife safer. The researchers found that the overall risk estimates of diseases were generally low, and removing fences may not increase the risk of pathogens crossing over.
Researchers at Florida Atlantic University have developed a patent-pending shark deterrent that can be used to reduce bycatch in fisheries. The device produces an electric field that repels sharks from bait without affecting target fish, and has been shown to reduce catches of coastal sharks by 62-70%.
A three-month study using hair snares and remote cameras collected data on coastal marten population and habitat in a 150-square-mile area. The findings indicate that martens are most numerous at high elevations with consistent winter snowpack, and at lower elevations in ravines and riparian areas.
A new study reveals how beluga whales in Alaska's Bristol Bay survive through a surprising strategy: they mate with multiple partners over several years. This polygynandrous system helps maintain genetic diversity despite the population's small size and isolation.
A study led by Dr. Frédérik Saltré suggests that sterilizing 22% of adult females annually could stabilize the population at an estimated cost of $34 million over 25 years. This approach prioritizes both animal welfare and ecosystem health, offering a humane solution to the unsustainable koala numbers.
New research from Simon Fraser University finds that Canada is failing to monitor the health of Pacific salmon populations, with 44% lacking sufficient data. The decline in monitoring is particularly concerning as salmon face the dual threat of climate change and industrial projects set to be fast-tracked by the federal government.
A new global study finds that nearly half of livestock production occurs in areas with destocking, a process that poses new ecological and land management challenges. Destocking can increase wildfire risk and biodiversity decline, but also enables ecosystems to capture more atmospheric carbon dioxide.
Research shows that conservation efforts can be more effective if they focus on why people buy ivory rather than just promoting its illegality. Studies suggest that targeting specific audiences and using behavioural theory can help change consumer behaviour.
Research led by UMass Amherst has pinpointed suitable habitats for Myanmar's Bengal tigers, Indochinese leopards, and Mainland clouded leopards. The study suggests that many existing protected areas will continue to be critical in the future, but require additional protection and connectivity solutions to ensure the big cats' survival.
A new study reveals that elephants, giraffes, and rhinos are unable to get enough salt from their habitats, leading to sodium deficiency. The researchers found that larger-bodied species are more affected by sodium scarcity, which influences their habitat selection and behavior.

This approach delivers significant ecological and cultural benefits, increasing human and ecological wellbeing by nearly 60%.
A new study suggests that coyotes are more likely to overlap with humans in areas with high levels of open space, such as parks and golf courses. The analysis found that coyotes were attracted to areas with moderate levels of open space, like parks or golf courses, where they could find food and shelter. In contrast, coyotes may be les...
A new study from the University of Illinois found that about half of Oregon's elk population carry a gene variant that makes them less susceptible to Chronic Wasting Disease (CWD). This could help slow down the spread of the disease in the state. The research also highlights the importance of monitoring and managing cervid populations.
Research analyzing over 170 studies reveals human impacts like hunting and land-use changes have a greater impact on prey populations than large carnivores. Large predators do control populations of prey species under specific conditions, but effects are often spatially constrained or influenced by competing species.
The study warns that connecting isolated habitats can lead to the spread of diseases and invasive species, while also increasing wildfire risks. To mitigate these effects, researchers recommend implementing cost-reduction strategies such as disease surveillance, habitat filters, and fire breaks.

The study's code is publicly available, allowing conservationists to tailor their solutions to specific climates.
Gray wolf pups are born nearly helpless, but their mothers take risks to move them close to prey, such as elk, which is crucial for conservation efforts. The study's findings counter years of assumptions that migratory mammals can escape predation in spring due to immobile offspring.
The Rhisotope Project uses low-level radioactive isotopes in rhino horns to track and intercept trafficked horns, aiming to disrupt the illegal trade. Researchers have confirmed the process is safe for animals and effective in making horns detectable through international customs systems.
A study from the University of Georgia found that lions and hyenas tend to stay near roads with less tourist traffic, particularly during the dry season. The animals often visit waterholes for drinking or hunting, but hyenas may avoid areas with high competition from lions.

The method combines aerial imagery with statistical modeling, offering a new tool for conservationists to monitor vulnerable animal populations.
A 26-year study found that removing feral animals like cats and foxes from a reserve sparked an ecological transformation, favoring the growth of smaller rodents like Bolam's mouse and spinifex hopping mouse. Larger species like plains mouse and stripe-faced dunnart also surged in population after five to nine years.
A new study reveals that koalas only spend around 10 minutes per day on the ground, which is linked to two-thirds of recorded koala deaths. The research used GPS loggers and accelerometers to analyze fine-scale movement patterns, finding that koalas move with little urgency and spend most of their time in trees.
A study by University of Göttingen researchers found that mixed deciduous-conifer forests promote coexistence between red squirrels and dormice. The team observed both species living side by side in these forests, suggesting a potential role for mixed forest management in supporting biodiversity.
