Streams and rivers across much of the U.S. are getting saltier and more alkaline due to an uptick in the use of road deicers and fertilizers in recent decades, according to a 50-year-long analysis of 232 monitoring sites by the U.S. Geological Survey.
It’s simple math, says a University of Alberta conservation biologist. More roads equals fewer grizzly bears.
In a recent study examining a non-invasive DNA (hair collection) dataset of grizzly bear activity in British Columbia, Clayton Lamb and his colleagues determined what scientists have long suspected: higher road density leads to lower grizzly bear density—a critical problem for a species still rebounding from a long period of human persecution.
A team of scientists at the Keck School of Medicine of USC is looking to some deep sea dwellers to create a better way to develop cancer-fighting therapies. Harnessing the power of the enzymes that give these marine animals the ability to glow, the team created a test that makes it easy for researchers to see whether a therapy is having its intended effect — killing cancer cells. The results of their study were published in Scientific Reports Jan. 9.
The Great Lakes will have a network of well-equipped guardians thanks to a plan hatched by a UWindsor researcher with funding from the Canada Foundation for Innovation and Ontario’s Ministry of Research, Innovation and Science and Ministry of Economic Development and Growth.
Aaron Fisk and his nine collaborators will receive $15.9 million for the Real-time Aquatic Ecosystem Observation Network (RAEON), a collaborative research project which will provide infrastructure and data management for Canadian scientists to carry-out cutting-edge research on freshwater ecosystems.
Plastic bags are known for their environmental impact. They slowly release toxic chemicals once in the soil, for instance, and find their way into the guts of animals that often choke and die as a result.
Un nuevo estudio descubrió que los niveles de las poblaciones de peces comerciales podrían verse perjudicados a medida que el aumento de la temperatura del mar afecta su fuente de alimentos. Científicos de la Universidad de Adelaida han demostrado cómo el cambio climático puede conducir al colapso de las "redes alimenticias" marinas.
