The range-resident logistic model incorporates interactions between multiple animals, providing a more accurate prediction of population sizes and helping inform real-world conservation recommendations.
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.
Researchers from the University of East Anglia argue that placing social justice at the heart of global restoration initiatives is vital for success. The study found that ecological targets should be aligned with local social, economic, and cultural ones to ensure holistic and long-term thinking.
A new study in Botswana explores the effectiveness of bee-sound barriers in deterring elephants from raiding crops. While results show a positive reaction from some elephants, differences in response rates between Botswana and other countries suggest context-specific factors are at play.
A recent study found that releasing rehabilitated Golden Eagles can be an effective means of compensating for eagle deaths due to human actions. However, the study revealed that only a few rehabilitated eagles survive and integrate into the wild population, raising questions about the long-term efficacy of rehabilitation efforts.
A new analysis challenges traditional conservation strategies by highlighting the importance of sustainable pastoralism in protecting global biodiversity. Rangelands harbor vast biodiversity and support millions of people, yet only a small percentage receive formal protection.
