In the United States, the removal of dams now outpaces the construction of new ones—with more than 1,400 dams decommissioned since the 1970s—and a new study (link is external) suggests that the ecosystem effects of dam removal can be predicted.

Climate change has fueled coral reef bleaching throughout the tropics, with negative consequences for reef ecosystems and the people who depend on them. 

In a new study from UBC’s Okanagan campus, researchers have discovered a surprising new source of carbon dioxide (CO2) emmissions—bicarbonates hidden in the lake water used to irrigate local orchards.

Using telemetry units in hospitals to monitor patient health is standard practice. Now, a similar approach is proving to be invaluable for dolphins, too. 

A collaborative effort among the fishing industry, scientists and resource managers has led to a significant reduction in seabird bycatch in Alaskan longline fisheries since 2002, a new study documents, but researchers say that bycatch incidents are now increasing.

One of the largest field experiments ever conducted is providing the best evidence yet in support of a key Darwinian theory—that interactions between species are stronger toward the tropics and at lower elevations.

There is enough room in the world’s existing parks, forests, and abandoned land to plant 1.2 trillion additional trees, which would have the CO2 storage capacity to cancel out a decade of carbon dioxide emissions, according to a new analysis by ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university.

Fossil fuel combustion is the main contributor to black carbon collected at five sites around the Arctic, which has implications for global warming, according to a study by an international group of scientists that included a team from Baylor University.

Simply protecting small forests will not maintain the diversity of the birds they support over the long run, a Rutgers-led study says. 

In a new statement, the European Academies’ Science Advisory Council (EASAC), which represents the national science academies of the EU Member States, Norway, and Switzerland, says its latest analysis reveals that technologies and techniques for removing CO2 from the atmosphere are becoming even more significant with the failure to reverse the growth in global emissions.
