A squid biologist takes to the streets — and Skype — to share scientific knowledge.

Human activities have imperiled our waterways — along with almost one-third of freshwater fish and many other aquatic species.

Saving endangered species sometimes means knowing where they used to live — before scientists started studying them. For that, we need historical ecologists.

Lost in much of the coverage of the region’s water woes is the ecological crisis caused by prolonged drought, climate warming and development.

An upcoming project would change the flow of the Mississippi River and its sediment to make up for land the coast is losing due to climate change and sea-level rise.

Addressing environmental threats in Antarctica could help spur global action, an expert says.

The nonprofit Adventure Scientists unites skilled outdoors people with scientists to help drive critical conservation work.
