Like many parasites, nematomorphs are known to manipulate their hosts' behavior to complete their life cycles. Also known as horsehair worms, among other names, these creatures develop in their hosts' body cavities and lure their terrestrial arthropod victims into the water, where the parasites reproduce.

When Caitlin Bloomer wrestled the massive Crawzilla crawdad—yes, that's its actual common name—out of the muck during a biological survey in Kentucky, she was convinced it was the largest crayfish ever recorded.

Various studies have shown that local loss of plant species within patches (i.e., α-diversity loss) hampers plant biomass production, raising concerns about the consequences of biodiversity loss. How....

In adult Atlantic salmon, individual variation in migration and movement within rivers during spawning (i.e., reproductive movement, RM) is an important component of overall reproductive investment t...

There is growing interest in nature-based hybrid flood risk mitigation, in which wetland ecosystems, such as tidal marshes, are an integral part. Tidal marshes can attenuate wave loading on defense s...

The effects of winter environmental conditions on lake ecology can be highly variable. Ice and overlying snow isolate the water below, impeding exchange of materials among water, atmosphere, and the ...

Large-scale oyster reef restoration in the Chesapeake Bay is successfully creating three-dimensional habitats that support larger, more diverse fish communities, according to new research from scientists at the University of Maryland, Baltimore County (UMBC), the Smithsonian Environmental Research Center and the National Oceanic and Atmospheric Administration (NOAA).

New GPS tracking on African wild dogs found they could travel long distances to find mates, but more than half did not survive the journey.

Some types of marine life appear to have it easy. While exploring thousands of meters below the waves in the Chilean Margin in the southeastern Pacific Ocean, scientists observed tiny shrimp-like crustaceans known as amphipods (Mesopleustes abyssorum) clinging tightly to much larger giant sea spiders (Colossendeis colossea) that were scuttling on the ocean floor.

The first episode in our third season of the series highlighting di...

The unlikely dispersers help propagate a mushroom-looking plant

Understanding the mechanisms that promote native seedling establishment in disturbed ecosystems is key to improving the biodiversity and function of landscape restorations. Over seven growing seasons...

Every 13 or 17 years, swarms of cicadas emerge from the ground, their black bodies, orange-tinged wings and ruby-red eyes enveloping trees and forests.

In the Himalayan region, habitat loss from infrastructure development and land use changes threatens biodiversity by degrading biological corridors. Despite increased protected areas (PAs), maintaini...

The Democratic Republic of Congo's (DRC) tropical forests stretch across an extraordinary landscape of rivers, wetlands, savannas and towering trees.
