A new study reveals that biofuels could hasten climate change due to the destruction of tropical rainforests. The study found that it will take over 75 years for carbon emissions saved through biofuel use to compensate for the carbon lost when these forests are converted into plantations.
Sarah Keenan Jacobi, a Lincoln Park Zoo researcher, has been awarded the prestigious Smith Fellowship to develop a framework for efficiently allocating resources for conservation. The fellowship program will support her research on managing habitat and controlling invasive species such as reed canary grass.
A new study by conservation biologists from the University of California, Berkeley found that parks with public access have significantly lower populations of native carnivores such as coyotes and bobcats. The researchers believe that human disturbance may be driving these animals away from heavily visited areas.
A new Texas A&M University program aims to tackle conservation challenges by integrating biology, culture, and governance. Led by Dr. Lee Fitzgerald and Dr. Amanda Stronza, the project will train students in interdisciplinary research and fieldwork to address pressing issues like invasive species, habitat loss, and social conflict.
Researchers found that Magellanic Penguins in Argentina's largest colony can handle up to 70,000 annual visitors without significant stress or harm. However, the study highlights the challenges of quantifying long-term consequences of human disturbance on wildlife.
Researchers found that newly hatched magellanic penguin chicks in breeding grounds with large numbers of human visitors show a significant spike in stress-related hormone levels. As the chicks grew older, their behavior towards humans changed, with those in tourist areas becoming more tolerant but still exhibiting caution.
Blast fishing remains a widespread issue despite Indonesia's ban in 1985. To combat this, programs that decrease destructive fishing practices are critical for ecosystem restoration and economic value., Gentle, low-cost care can help restore coral reefs.
A new study warns that increased gas development in the Greater Yellowstone Ecosystem is putting long-distance migratory species like pronghorn antelope at risk. The authors suggest establishing protected migration corridors to safeguard these traditional migrations.
The giant catfish, a migratory species in Southeast Asia, is facing extinction due to the destruction of its habitats. Conservation efforts are underway to protect this vital species and the ecosystem it supports.
A special section of BioScience provides in-depth analyses of assessment systems for protected area management effectiveness. Key findings include the need for more widespread use of assessments and monitoring, as well as the identification of critical management issues such as funding, staffing, and community relations.
Researchers estimate between 2 and 100 million global species, developing six methods to assess biodiversity in a single habitat. Three methods proved effective even with limited data, while spacing ecoregions evenly throughout the continent yielded the best results.
A recent study suggests that roads are a major threat to US turtle populations, with over 5% of turtles likely to die while crossing roads. The researchers recommend establishing buffer zones around aquatic habitats and building road crossings to mitigate this issue.
Researchers have developed a new genetic shark-identification test that is quick, accurate and relatively cheap. The test has been evaluated on 33 closely-related known species and found to be nearly 100% accurate, with an average accuracy of over 99%, according to Shivji and his colleagues.
Researchers estimate that eastern North American reserves must be at least 1,000 square miles in size to prevent loss of species. This is significantly smaller than the current sizes of most reserves, which are often not enough to safeguard biodiversity.
A recent study published in Conservation Biology found that moderate cattle grazing has little to no effect on Texas tortoise populations. The researchers compared tortoise populations in grazed and ungrazed pastures and found no differences in abundance, size, growth rate, or adult survival.
