The leatherback sea turtle is the largest living turtle and a critically endangered species. Saving leatherback turtles from extinction in the Pacific Ocean will require a lot of international cooperation, however, because the massive turtles may visit more than 30 different countries during their migrations.
A new study uses tracking data for 14 species of migratory...
Eating in 10-hour window can override disease-causing genetic defects, nurture health
Scientists at the Salk Institute found that mice lacking the biological clocks thought to be necessary for a healthy metabolism could still be protected against obesity and metabolic diseases by having their daily access to food restricted to a 10-hour window.
The work, which appeared in the journal Cell Metabolism on August 30, 2018, suggests that...
Are vulnerable lions eating endangered zebras?
Are Laikipia's recovering lions turning to endangered Grevy's zebras (Equus grevyi) for their next meal?
That's what a team of researchers led by WCS and WWF set out to discover -- whether the comeback of a top predator -- in this case lions in Laikipa County, Kenya -- were recovering at the expense of Grevy's zebras,...
Biomechanics of chewing depend more on animal size, not diet
Chewing: We don't think about it, we just do it. But biologists don't know a lot about how chewing behavior leaves telltale signs on the underlying bones. To find out, researchers at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo have been studying the jaw joints of carnivorans, the large...
Aspen is making a comeback in and around Yellowstone National Park, because of predators
The reintroduction of wolves into Yellowstone National Park is tied to the recovery of aspen in areas around the park, according to a new study.
The study was published today in the journal Ecosphere.
This is the first large-scale study to show that aspen is recovering in areas around the park, as well as inside the park...
Mapping trees can help count endangered lemurs
The vast majority of lemur species are on the edge of extinction, experts warn. But not every lemur species faces a grim future. There may be as many as 1.3 million white-fronted brown lemurs still in the wild, for example, and mouse lemurs may number more than 2 million, a Duke-led study has shown.
"For some...
