A fungal pathogen that has wiped out bat populations across the eastern third of the U.S. has now been found in Texas, according to state wildlife officials, who documented the fungus for the first time on two new bat species: the cave myotis and a western subspecies of Townsend’s big-eared bat.
White-nose fungus first emerged in 2006 in New York and his since spread into 30 states and killed at least 5.5 million bats. Wildlife conservation advocates said the recent announcement from is a biological disaster, considering the potential risks to huge, world-famous bat colonies that thrive in unique cave ecosystems in the state.

Ranching, farming groups sue to end legal protections
Wildlife conservation advocates are helping fend off a nuisance lawsuit by a right wing group that seeks to end state endangered species protection for wolves in California. The lawsuit, brought against the California Fish and Wildlife Commission by the Pacific Legal Foundation, falsely claims that wolves are ineligible for state protection. Like many other legal actions filed by the group, this one is aimed mainly at harassing government agencies and others working in the public interest.
Scientists are currently mapping the biological damage caused by global warming
At the end of eastern Australia’s long, hot summer, ocean scientists are once again seeing devastating coral die-backs in the northern reaches of the Great Barrier Reef. Over the next few weeks, they’ll venture underwater to study how the coral communities responded to a second straight year of overheated water.
When temperatures pass a threshold, the coral expels its symbiotic algal partner, leaving underwater wastelands of white-washed reefs. The scientists will also use survey flights above the reef, and even satellite imaging as they mobilize to document one of global warming’s most devastating impacts. There has been a prolonged global mass bleaching under way for the past year, and climate researchers say nearly all the world’s corals will be at risk by mid-century under projected global temperature increases.

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.
