Climate change and other impacts from human activities are enabling jackals to spread into parts of Europe, scientists said after documenting the first living golden jackal in the Czech Republic. The mammal, native to northern Africa and southern Eurasia, was photographed by motion sensors cameras several times just 40 kilometers from Prague, according to a new study published in the open access journal ZooKeys.
“The habitat, where the golden jackal decided to settle, resembles the landscapes which these animals prefer in their natural distribution area, the Balkans – an open grass-shrubland surrounded by a forest. It is one of the warmest areas in the country, with mild winters.The observed animal was mostly active at dusk and dawn, with majority of the sightings occurring in the morning hours,” said researcher Klára Pyšková, who co-authored the paper with a group of researchers from Charles University and Institute of Botany of the Czech Academy of Sciences, among them her supervisors Ivan Horáček and David Storch.

Jaguars making their from Mexico back to the southwestern U.S. apparently won’t be getting much help from the U.S. Fish and Wildlife Service. The agency this week released a draft recovery plan that puts the conservation burden on Mexico. The plan’s criteria for recovery and removal of the jaguar from the “endangered” list could be met without any jaguars occupying any of their vast historic range in the United States, according to wildlife watchdogs with the Center for Biological Diversity.
The draft was released just a short time after a second jaguar was documented in the Southwest. Between 2011 and 2015, another jaguar was seen several times around the Santa Rita Mountains southeast of Tucson. Another jaguar called “Macho B” was photographed repeatedly from 1996 until he was killed by the Arizona Department of Game and Fish as a result of a botched capture operation in 2009.
“Jaguars are making their presence known in the southwestern United States so it’s disappointing to see the U.S. Fish and Wildlife Service put the focus of jaguar recovery solely in Mexico,” said Michael Robinson of the Center for Biological Diversity. “By excluding the best remaining unoccupied jaguar habitat, this plan aims too low to make a difference in saving the jaguar. It’s an extinction plan, not a recovery plan.” Continue reading “Draft plan for jaguar recovery panned by wildlife advocates”→
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.
