Toxic lead is back on the menu for many wildlife species, as newly appointed Interior Secretary Ryan Zinke revoked a U.S. Fish and Wildlife Service order that had banned lead hunting ammunition on federal wildlife reserves after a years-long campaign by wildlife advocates.
The USFWS order was finalized the day before Donald Trump was inaugurated as president. In his reversal, Zinke made no reference to the extensive body of science showing that lead ammunition is harmful to wildlife.
Study says 90 percent of all predatory fish species have been lost from Caribbean coral reefs
Not all Caribbean reefs are created equal, say researchers with the University of North Carolina at Chapel Hill, who recently identified reef areas they are calling “supersites”that could help restore populations of predatory fish needed maintain an ecological balance.
That’s the good news. The bad news is their study also shows that up to 90 percent of predatory fish are gone from Caribbean coral reefs. The research suggests that these supersites should be prioritized for protection and could serve as regional models showcasing the value of biodiversity for tourism and other uses.

Uptick in tropical cyclones intensifies impacts, hampers recovery
Along with the widely reported bleaching threat from over-heated oceans, coral reefs in many parts of the world also may have to cope with intensifying tropical storms, which could make it even more difficult for them to survive the Anthropocene.
The threat of roads to carnivore species around the world has been seriously underestimated, according to a new study that looked at the issue on a global scale.
After looking at 232 carnivore species around the world (out of a total of about. 270 existing species) and assessing how severely these are affected by roads cut through their habitat, the researchers concluded that some rare species are even at risk in areas with low road densities. The study, published in the journal Global Ecology and Biogeography, calculated natural mortality rates, reproduction and carnivore movement patterns, determining the maximum density of roads that a species can cope with.

Small hibernating bat colonies need protection to prevent extinction
Between collisions with wind turbines and deadly white-nose syndrome, endangered Indiana bats may not have much of a chance of recovering, according to a recently published U.S. Geological Survey study.
Federal biologists say they can boost the population of grizzly bears in the North Cascades ecosystem by relocating the predators from other areas. The National Park Service and the U.S. Fish and Wildlife Service this week released a draft plan (open for public comment), for increasing the total number of bears in the region to 200. Bt current estimates, only about 10 remain, too small a population to sustain itself. According to the draft plan, grizzly bears could be relocated from either northwestern Montana or south-central British Columbia.
“We’re happy to see the agencies taking a step in the right direction to restore grizzly bears to the North Cascades,” said Andrea Santarsiere, a senior attorney with the Center for Biological Diversity. “Without a helping hand, grizzly bears are likely to disappear from the Pacific Northwest.” Continue reading “Feds eye grizzly reintroduction in North Cascades”→
