The musk ox, an Arctic species that is a holdover from the Pleistocene, survived terrible climate changes when mastodons and sabertooths went extinct. That may be as much a result of its social structure as its shaggy coat.
"Manatees died in record-breaking numbers this year, but not from being hit by boats or poisoned by Red Tide. Instead, the largest group of the 699 manatees that were killed as of Dec. 5 were done in by bad weather."
"They call it the 'Jaws' effect. Inspired by the 1975 movie about a great white shark that terrorized a tourist town, waves of fishermen piled into boats and killed thousands of the ocean predators in shark fishing tournaments."
"Beetles killing trees in North America, blue tongue disease ravaging livestock in Europe, and borers destroying African coffee crops are examples of migrating invasive species not getting enough attention at global climate talks, scientists said on Wednesday."
"To protect the declining population of the western Steller sea lion, the National Oceanic and Atmospheric Administration will restrict commercial fishing for Atka mackerel and Pacific cod, the animal’s main source of food, off parts of the Alaska’s western Aleutian Islands."
The timing of a U.S. Fish and Wildlife Service decision to propose listing of the greater sage-grouse as a threatened or endangered species is coinciding with the presidential election and the rapid expansion of the influential oil and gas industry.
This invasive grass that already has a grip on about 2 million acres in the West makes the rangeland it invades virtually worthless for grazing, harms many animals that contact it or try to eat it, increases wildfire risk, and creates monocultures that have very low biodiversity and crowd out numerous native plant and animal species.
The map and report on known greater sage grouse high-density breeding populations is a starting point that can be refined with the input of state fish and wildlife agencies. But you can use it right away as you cover various land use and environmental issues.
"A federal judge [Dec. 2] rejected the request of five Great Lakes states for a preliminary injuction that would force the U.S. Army Corps of Engineers and the Metropolitan Water Reclamation District of Greater Chicago to keep invasive Asian carp out of the Great Lakes."
"At a 2 p.m. news conference streamed live over the Web, scientists at the National Aeronautics and Space Administration said they found microbes in the mud beneath a California lake that can use arsenic -- usually considered toxic -- rather than phosphorus as one of the building blocks of its DNA. Phosphorus is one of the elements that sustains all other life forms on earth."
