Researchers at the University of California, Davis, have identified 52 potential wildlife corridors linking protected areas across Tanzania. Using a cost-effective combination of interviews with local residents and a land conversion dataset for East Africa, they found an additional 23 corridors over those previously identified by Tanzanian government reports.

Forgot to water that plant on your desk again? It may soon be able to send out an SOS.

Soil characteristics like organic matter content and moisture play a vital role in helping plants flourish. It turns out that soil temperature is just as important. Every plant needs a certain soil temperature to thrive. If the temperature changes too quickly, plants won’t do well. Their seeds won’t germinate or their roots will die.

Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?

Study Bolsters Theory of Heat Source Under West Antarctica

A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet.

Central to the field of ecology is the mantra that species do not exist in isolation: They assemble in communities — and within these communities, species interact. Predators hunt prey. Parasites exploit hosts. Pollinators find flowers.

With amphibian populations declining around the world and funds to find the causes scarce, a team of Penn State researchers has shown that an unorthodox tactic will make it easier and therefore less expensive to capture adult salamanders and frogs.

Greenhouse gas emissions caused by urban households’ purchases of goods and services from beyond city limits are much bigger than previously thought. These upstream emissions may occur anywhere in the world and are roughly equal in size to the total emissions originating from a city’s own territory, a new study shows. This is not bad news but in fact offers local policy-makers more leverage to tackle climate change, the authors argue in view of the UN climate summit COP23 that just started. They calculated the first internationally comparable greenhouse gas footprints for four cities from developed and developing countries: Berlin, New York, Mexico City, and Delhi. Contrary to common beliefs, not consumer goods like computers or sneakers that people buy are most relevant, but housing and transport – sectors that cities can substantially govern.

The recent uproar about seats on a British Airways flight crawling with bedbugs is only one of the unintended consequences that urbanization worldwide has on evolution, says a University of Toronto researcher whose new study takes a comprehensive look at those consequences.
 
 “As we build cities, we have little understanding of how they are influencing organisms that live there,” says Marc Johnson, an associate professor of biology at U of T Mississauga who is also a director of the University of Toronto’s Centre for Urban Environments.

Scientists have used satellite tracking and a crime-scene technique to discover an important feeding ground for green turtles in the Mediterranean.
