Mahi-mahi were more likely to be eaten and less likely to spawn after being exposed to sublethal concentrations of oil, raising concerns about the risks oceanic drilling pose to life in the ocean.

A new modeling technique aims to help scientists and policymakers detect declines in genetic diversity based on habitat loss.

A study suggests that pathogens affecting other species can indirectly harm human health.

Five major El Niño events per century could lead to fewer fishes that thrive in cold water and more terrestrial birds in eastern coastal ecosystems.

Frogs invest in cognitive capacity to avoid predators—up until there are too many hungry snakes around for the evolutionary strategy to pay off.

Parts of Southeast Asia where human and bat population densities are highest could be infection hotspots, a study finds.

The Scientist speaks with Trier University’s Henrik Krehenwinkel, whose group recently detected traces of hundreds of arthropod species from a sample of dried plants—in this case, the contents of a tea bag.

A study yields insights into how predator-prey dynamics may shift with climate change, but many questions remain.

Off the western Australian coast, in Shark Bay, a field of seagrass big enough to cover Washington, DC, has flourished for more than four millennia, a new study finds.

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.
