Some snake populations appear at-risk from spreading fungal pathogen
First the chytrid fungus started killing amphibians, then white-nose syndrome emerged to devastate bat populations, and now, there’s Ophidiomyces ophiodiicola, a snake-killing fungus that appears to be much more widespread than thought, according to new research from the U.S. Geological Survey.
The USGS report concluded the fungus is present in at least 20 eastern states and in many snake species not previously known to harbor the fungus. These findings increase the total number of confirmed susceptible snake species to 30. Snakes affected by Snake Fungal Disease include the threatened eastern massasauga rattlesnake. The research also shows that SFD infections are often mild, but there are unknown factors that cause outbreaks of severe skin disease and death.

A federal judge in Montana has once again ruled that the U.S. Fish and Wildlife Service violated the Endangered Species Act when it excluded Colorado from a critical habitat designation for threatened lynx. In the end, the rare cat may yet get some protected sanctuaries in the Colorado high county.
Disease may be exacerbated by warm water, low stream flows
The Yellowstone River, part of Montana’s iconic western landscape, is once again beset by environmental woes, as a rapidly spreading fish kill has spurred state resource managers to close the river to all recreational uses, including fishing, boating and tubing. Biologists with Montana Fish, Wildlife and Parks said they’ve counted more than 2,000 dead mountain whitefish, and the estimate the total mortality in the tens of thousands. The river was also hammered by an oilspill in 2011 after pipeline burst. Continue reading “Environment: Massive fish kill reported in Yellowstone River”→
‘Reducing immediate impacts is essential to tackling the biodiversity crisis’
About 75 percent of the world’s threatened species are at risk because of human impacts to their environment and unsustainable harvesting, according to a new study in the journal Nature.
“Addressing these old foes of overharvesting and agricultural activities are key to turning around the biodiversity extinction crisis” said lead author Sean Maxwell of the University of Queensland, “This must be at the forefront of the conservation agenda.”
Scientists from the University of Queensland, the Wildlife Conservation Society and the International Union for Conservation of Nature studied 8,688 species on the IUCN Red List. They found that 72 percent of species are imperiled by unsustainable harvesting. The production of food, fodder, fiber and fuel crops; livestock farming; aquaculture; and the cultivation of trees imperils another 62 percent. By comparison, 19 percent are considered threatened by climate change. Continue reading “New report IDs biggest global threats to wildlife”→
Alaska’s native bears and wolves — at least those living in national wildlife refuges — may get a break from the federal predator control program, as the U.S. Fish and Wildlife Service this week finalized new regulations that ban the controversial practice of culling carnivores through aerial gunning, baiting, trapping, and killing mother bears and cubs and wolves and pups in their dens.
Many bird species could lose between 78 and 85 percent of their existing habitat
Birds and reptiles in the Southwest that live in fragmented habitat will be hit hardest by global warming in the decades ahead, according to a new study by scientists with the U.S. Geological Survey and the Northern Arizona University.
The researchers took a close look at about 30 different animals, including well-known species such as the Gila monster, horned lizard, chuckwalla, Sonoran desert tortoise, pinyon jay, pygmy nuthatch, sage thrasher and black-throated sparrow.
Activists say public was short-changed on comment period
Wildlife advocates are going to court to challenge a proposed grizzly hunting plan in Wyoming. A lawsuit filed last week alleges that he Wyoming Game and Fish Commission illegally fast-tracked approval of the plan without allowing adequate public comment.
The approval would authorize the state’s first trophy hunt of grizzly bears in 40 years, but the public only had 30 days to review and comment on the plan — far too short to be able to evaluate the biological consequences of the proposed hunt. The commission simultaneously adopted a tri-state memorandum of agreement with Idaho and Montana to formalize quotas for grizzly hunts, allocating over 50 percent of the quota to Wyoming.
