Hydropower is the dominant source of energy in the Amazon region, the world’s largest river basin and a hotspot for future hydropower development. 

Research has shed new light on the impact of humans on islands’ biodiversity. 

Corals are the foundation species of tropical reefs worldwide, but stresses ranging from overfishing to pollution to warming oceans are killing corals and degrading the critical ecosystem services they provide.

A new study documents the formation of a 3,000-square-kilometer rift in the oldest and thickest Arctic ice.

The recent discovery of a sleeper fish in Akita Prefecture, Japan, by researchers from the University of Tsukuba is a first for this area and the northernmost record for this species.

Coral reefs are the rainforests of the seas, and 30 percent of all marine biodiversity depends on them.

Urbanisation appears to be another key factor for insect decline. 

In a new paper published in the Journal of Applied Ecology, environmental science and management professor Elise Granek and lead author Casey Lewis, PSU alumna, report the findings of a census of zooplankton communities in non-native mangrove habitats and open coastline on the island of Moloka'i, Hawaii. 

As the ice-and-snow rubble known as mélange melts in Antarctica’s ice shelves, rifts can grow and icebergs break off even in the brutal cold of winter.

Many of the world’s largest rivers are experiencing significant changes in their chemical composition as a result of natural and human activity, according to new research.
