A survey showed that 91 percent of the reef experienced bleaching despite this year’s cooler, wetter conditions associated with the La Niña weather pattern.

Nearly all mouse sperm have hooks on their heads. But new research suggests the structures slow them down—so what exactly is their purpose?

The study estimates that one-fifth of reptile species worldwide are at risk of extinction.

Laboratory experiments find that Toxoplasma, Cryptosporidium, and Giardia can congregate on microplastic beads and fibers, suggesting they might make their way into and around the world’s oceans by hitching rides on tiny bits of trash.

Contrary to what researchers had assumed, Egyptian fruit bats don’t rely solely on sight to orient themselves as they drink and forage for food in daylight. 

Assumed to have gone extinct more than 30 years ago, Gasteranthus extinctus has been rediscovered by scientists working in Ecuador.

Hoffmann traveled through Chile cataloging its rare flora. Later, she fought to defend the country’s forests from commercial deforestation.

A study finds that dozens of bird species are nesting up to 25 days sooner each year than they were a century ago, likely due to climate change.

When soil heats up, microbes scale back protein synthesis machinery by making use of higher reaction rates that occur at higher temperatures, a study finds.

Half or more of the world’s largest forest is in danger of transitioning into grassland, researchers say.

Levels of pharmaceuticals considered unsafe for aquatic organisms were found at more than one-quarter of sampling sites.

Corals that previously experienced heat stress respond better the next time around. Researchers are trying to figure out how, and hope to one day take advantage of the phenomenon to improve coral restoration efforts. 

A new study of tree biodiversity estimates that Earth boasts 14 percent more tree species than previous efforts have identified.

This University of California, Santa Cruz, biologist is dedicated to her marine mammal research, as well as to making the field more diverse and equitable.

The famous ecologist was a lifelong champion for conservation.

The naturalist was recognized for his work on social behavior and pheromones in ants and as a champion of wildlife conservation.

The Scientist speaks with organismal biologist Xavier Glaudas about possible reasons for his recent finding that male Montpellier snakes cannibalize female conspecifics.

Across the tree of life, animals use sound and other vibrations to glean valuable sensory information about their environments even before they are born.

Recent findings buck the traditional idea that embryos are passive agents and instead suggest that by tuning into vibrations, organisms can better prepare to enter the outside world.

The Princeton University evolutionary biologist studies how animals are changing due to human activity.
