A Colorado State University experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return – at least, not for a very long time. 

Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. 

New research led by Monterey Bay Aquarium and the University of California, Santa Cruz, reveals that denser, and more sheltered, kelp forests can withstand serious stressors amid warming ocean temperatures. 

Nestling songbirds relocated as part of conservation programmes successfully learn the song repertoires they need to communicate – and ultimately survive – in the wild, a new study has found.

California sea otters were nearly hunted to extinction in the 19th century, with only a small number surviving along the central coast.

A collaborative team of researchers from the University of Massachusetts Amherst and the Wildlife Conservation Society (WCS), which runs the world’s largest field conservation program, has conducted first-of-its kind research into how global climate change affects African elephants.

How individual animals respond to climate change is key to whether populations will persist or go extinct. 

The pore-like structure of permeable pavements may help protect coho salmon by preventing tire wear particles and related contaminants from entering stormwater runoff, according to a Washington State University study.

Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity.

On a cliffside at Mesa Verde National Park in southern Colorado, a fuzzy bee was industriously gnawing at the red sandstone.
