Rare fish species in steep decline as global, regional temperatures soar
FRISCO — Rare fish living in desert freshwater springs in Nevada may be adapted to warm weather, but they may not be able to survive long-term global warming, researchers said this week, outlining the threats facing endangered Devils Hole pupfish.
At times, the population of the fish has been as low as just 35 individuals, and the geothermal water on a small shelf near the surface of an isolated cavern in the Nevada desert where the pupfish live is heating up as a result of climate change and is likely to continue heating to dangerous levels.
From the 1970s through the mid-1990s, the population appeared stable, but 1997 marked the start of a long-term decline that is probably linked with global warming, according to scientists who closely watch the fish. The population dropped to an all-time low of just 65 fish in the fall of 2013, with a further decline expected this year that will push the species toward extinction. Continue reading

Conservation and recovery plans will be crafted in partnership with coastal communities
FRISCO — Twenty types of coral in the Pacific and Caribbean will be listed as threatened under the Endangered Species Act, federal officials announced this week, citing declines of up to 90 percent in some species. Continue reading

Can monarch butterflies be saved?
Pesticides, habitat loss and GMO crops seen as main threats
FRISCO —As monarch butterfly populations dwindle to unprecedented low levels, activists say the colorful and far-ranging insects need protection of the Endangered Species Act to survive. In a formal listing petition to the U.S. Fish and Wildlife Service, a coalition of advocacy groups say the widespread use of pesticides and genetically modified crops are the biggest threats to the butterflies.

Proposed critical habitat designations could help protect dwindling loggerhead sea turtles in the Gulf of Mexico.
Findings may help protect dwindling population
FRISCO — The beleaguered population of loggerhead sea turtles in the northern Gulf of Mexico feeds in areas affected by the 2010 Deepwater Horizon spill and where they are threatened by other human activities.
The feeding areas for 10 turtles overlapped with an area that experienced surface oiling during the 2010 Deepwater Horizon oil spill. These sites, and others, also overlapped with areas trawled by commercial fishing operations and used for oil and gas extraction, U.S. Geological Survey scientists said after tracking 59 nesting females. That could be about 15 percent of the entire breeding females in the Northern Gulf of Mexico—a small and declining subpopulation of loggerheads that is federally classified as threatened.

Simple organisms process basic elements to survive
FRISCO —Tiny organisms living beneath the vast Antarctic ice fields can convert ammonium and methane into the energy required for growth, surviving in one of the most unlikely environments on Earth, according to scientists who studied a subsurface lake that hasn’t seen sunlight for millions of years.
“We were able to prove unequivocally to the world that Antarctica is not a dead continent,” said Montana State University professor John Priscu, the chief scientist of the U.S. project called WISSARD that sampled the sub-ice environment. Continue reading

National Park Service launches 3-year study on possible restoration
FRISCO — In a big move for grizzlies and wild ecosystems, the National Park Service this week launched a three-year environmental study to evaluate to possibility of restoring the apex predators to the North Cascades.
“This is the first stage of a multi-step process to help inform decisions about grizzly bear restoration in the North Cascades ecosystem,” said National Park Service Director Jonathan B. Jarvis. “The National Park Service and our partners in this effort haven’t made any decisions about the bear’s restoration at this time as federal law requires us to look at a range of options, including not restoring grizzlies to the area.” Continue reading

Feds map critical habitat for yellow-billed cuckoo
Will yellow-billed cuckoos make a comeback in Colorado?
By Summit Voice
FRISCO — The long endangered species odyssey of the yellow-billed cuckoo may be one step closer to resolution, as federal wildlife officials this week proposed designating more than half a million acres of critical habitat for the birds, sometimes known as rain crows for their habit of singing before a storm.
The bird was once common along most rivers and streams in the West, but the decline of the species, eyed for protection since 1986, shows how much human activities have degraded riparian riverside habitat. Yellow-billed cuckoos are neotropical migrants that winter in South America and nest along rivers and streams in western North America. Continue reading
