And for now, there is no smoking gun pointing to a single reason for the decline. That means there’s no easy answer, either, the scientists said, explaining that, across the U.S. there are multiple and geographically diverse factors that play role.
New study shows how to help recover endangered loggerheads
Nobody likes a dirty bedroom and sea turtles are no exception.
New research by scientists at the University of Florida shows that removing beach debris helps sea turtle nesting. At cleared beaches, the number of nests rose by as much as 200 percent, the study shows, while leaving the detritus decreased the number by nearly 50 percent.
With many sea turtle species classified as endangered or threatened, restoring nesting habitat is critical to keeping them alive, said Ikuko Fujisaki, the study’s lead author and an assistant research professor of wildlife ecology and conservation with the UF Institute of Food and Agricultural Sciences.

New survey results show as few as 60 remaining vaquita porpoises in the Gulf of California
The population of vaquita porpoises in the Gulf of California may be down to just 60 individuals, according to conservation advocates, who released the results of recent surveys in a press release last week.
Wolf advocates hope for more releases of captive-bred wolves
The U.S. Fish and Wildlife Service this week agreed to prepare a recovery plan for Mexican gray wolves by 2017. The court settlement will compel the federal agency to finally meet its legal obligation to ensure that the wolves can establish a healthy, sustainable population. The settlement may speed up the slow-going conservation and recovery effort.
The settlement came in response to a lawsuit filed by a coalition of wolf-conservation groups, environmental organizations and a retired federal wolf biologist. Less than 100 Mexican gray wolves exist in the wild, making it one of the most endangered mammals in North America. The settlement follows a September 2015 ruling by a federal judge in Tucson that rejected the government’s effort to dismiss the case.
Study suggests more protection needed for rare mountain predators
Biologists tracing the elusive Himalayan wolf say that new genetic studies show the species branched off from its relatives so long ago that they are divergent from the whole globally distributed wolf-dog clade. Based on that isolated genetic isolation, the Himalayan wolf should considered a species of particular conservation concern.
The decline of milkweed may not be the main factor driving monarch butterflies toward oblivion, according to a new study by Cornell University scientists. Weather, habitat fragmentation and dwindling sources of nectar in the autumn are also critical, the new study reports.
“Thanks to years of data collected by the World Wildlife Fund and citizen-scientists across North America, we have pieced together the monarch life cycle to make inferences about what is impacting the butterflies,” said Cornell University Prof. Anurag Agrawal.
Feds dial back proposed regs that would have made it harder to seek endangered species protection
Many plants and animals that are protected as endangered species in the U.S. got that status because conservation groups — representing concerned citizens — petitioned the federal government. It’s a process that’s explicitly mandated by the Endangered Species Act, but that has led to serious frustration among government biocrats and various extractive industries that specialize in exploiting public land resources.
In an attempt to try and cripple citizen groups, the U.S. Fish and Wildlife Service recently proposed making the petitioning process much more difficult by requiring pre-clearance from state agencies and limiting petitions to a single species. All in all, the proposal was aimed at trying to avoid giving protection to species that need it. Continue reading “Watchdog group keeps door open for endangered species petitions”→
