Greenland meltwater adds to AMOC weakening, but updated model finds no tipping point in si
The state of the Atlantic Meridional Overturning Circulation (AMOC) has been a hot topic among climate scientists in recent years. The AMOC is crucial for climate regulation because it pulls warm surface water from the tropics north and sends colder, deeper water south, redistrib

Parasites deliver long-chain omega-3 fatty acids to aquatic systems, feeding endangered fi
Wormlike parasites cause crickets to jump into streams, where the fatty insects nourish endangered fish. Ayano Medo and Takuya Sato sought to characterize the flow of eicosapentaenoic acid (EPA)—a nutritious long-chain omega-3 fatty acid—through aquatic and terrestrial ecosystems

Satellite record reveals US tidal wetland productivity rose 6% in 20 years
Carbon sequestration, climate regulation, biodiversity support and shoreline protection: These are all benefits provided by tidal wetlands. As the climate changes, the amount of carbon captured by these vital ecosystems may be changing as well.
How climate change affects interactions between owls and their prey
How climate change affects interactions between owls and their prey
A study published in Ecography has assessed how climate change may be destabilizing interactions between predators and prey in the wild—specifically, how owl–prey interactions have responded to environmental variability and resource availability over 24 years in the semi-arid eco
