The diversity and numbers of wild salmon in Northern B.C. have declined approximately 70 per cent over the past century, according to a new SFU study.

An international team of scientists, including two from Oregon State University, conducted a biological assessment of the world’s rivers and the limited data they found presents a fairly bleak picture.

Scientists at Oregon State University and the U.S. Forest Service have demonstrated that DNA extracted from water samples from rivers across Oregon and Northern California can be used to estimate genetic diversity of Pacific salmon and trout.

University of Central Florida researchers are homing in on the cause of a major disease of sea turtles, with some of their latest findings implicating saltwater leeches as a possible factor.

As climate change takes hold across the Americas, some areas will get wetter, and others will get hotter and drier.

Scientists have discovered a never-before-seen biodiversity pattern of coral reef fishes that suggests some fishes might be exceptionally vulnerable to environmental change.

Climate change is rapid in the Arctic. As the climate warms, shrubs expand towards higher latitudes and altitudes. Researcher Julia Kemppinen together with her colleagues investigated the impacts of dwarf shrubs on tundra soils in the sub-Arctic Fennoscandia.

Iron minerals and bacteria can be the main agents of carbon dioxide emissions from the soil. A soil scientist from RUDN University made this conclusion after studying the process of organic plant waste decomposition of the micro-level.

Coral reefs have thrived for millions of years in their shallow ocean water environments due to their unique partnerships with the algae that live in their tissues.

A new analysis of thousands of native and nonnative Michigan bees shows that the most diverse bee communities have the lowest levels of three common viral pathogens.
