‘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.

USFWS closes loopholes that helped illegal ivory traders
A new regulation finalized by the U.S. Fish and Wildlife Service will give federal investigators more tools to combat the illegal ivory trade, helping to close some loopholes that wildlife traffickers have exploited.
The rule, which is basically a near-total ban on the domestic commercial trade of African elephant ivory, is being touted as a significant step in protecting endangered elephants.
During a recent three-year period, an estimated 100,000 elephants were killed for their ivory, an average of approximately one every 15 minutes, and poaching continues at an alarming rate. The carcasses of illegally killed elephants now litter some of Africa’s premiere parks. Elephants are under threat even in areas that were once thought to be safe havens.

Report says more monitoring of wildlife needed on offshore oil drilling rigs
It only takes exposure to a teaspoon full of oil to kill some seabirds, but oil drillers off the coast of Canada are failing to adequately monitor small, persistent spills that can lead to chronic pollution and population-level impacts, according to a new study by scientists with York University.
The research published in the international journal, Marine Pollution Bulletin, looked at how offshore oil operators monitored and responded to small spills (less than 1,000 litres) for three production projects off the coast of Newfoundland and Labrador. It came after authorities failed to respond to three high-profile environmental assessments by Environment Canada that requested impacts on seabirds be monitored following small spills.

Scientists say Nile crocs may be thriving in Sunshine State swamps
The latest non-native species to invade Florida’s subtropical clime is a man-eater, according to University of Florida researchers who say they’ve genetically identified Nile crocodiles living in the swamps of the Sunshine State.
The aquatic reptiles can grow as long as 18 feet and weigh as much as a small car, and in their native habitat eat everything from hippos and zebras to humans. In Florida, they could eat native birds, fish and mammals, as well as the state’s native crocodile and alligators, said the researchers, have confirmed the capture of multiple Nile crocodiles in the wild, using DNA analysis.
