Research shows how climate shifts can play out in local ecosystems
FRISCO — Rare Galápagos penguins may be benefiting from shifts in trade winds and ocean currents, researchers said after tracking subtle climate shifts that have enlarged a cold pool of water the penguins rely on for food and breeding.
The trend could continue during the coming decades, helping to bolster northern hemisphere’s only penguin population, which has doubled from just a few hundred to about 1,000 in the last 30 years, the scientists said in paper to be published in Geophysical Research Letters, an American Geophysical Union journal.
“The penguins are the innocent bystanders experiencing feast or famine depending on what the Equatorial Undercurrent is doing from year to year,” said Kristopher Karnauskas, a climate scientist who performed the research while at Woods Hole Oceanographic Institution in Cape Cod, Massachusetts.

Report says fragmented habitat isn’t adequate for protection of species
FRISCO — After a detailed mapping analysis maps, wildlife conservation advocates say the federal government downsized important habitat for sage grouse.
The findings are outlined in a new report released by WildEarth Guardians. It compares protected areas to remaining key population hotspots. Almost 20 million acres designated as Priority Areas for Conservation disappeared from the Priority Habitat areas proposed in U.S. Forest Service and Bureau of Land Management sage grouse plans.

FRISCO — While many Australian animal species are being pushed toward extinction, humpback whales off both the country’s east and west coasts are making a strong comeback from the whaling era.
Recent research suggests humpback populations are growing at about 10 percent annually, and that populations have recovered to between 60 and 90 percent of pre-whaling numbers, according to a new study published in the journal Marine Policy. Continue reading

Greed is pushing elephants toward extinction.
Booming Asian economies fuel huge poaching and wildlife trafficking issues
FRISCO —Federal wildlife managers hope that a near-total ban on the U.S. ivory trade will help slow the slaughter of elephants poached for their tusks.
By some estimates, as many as 100,000 elephants were killed for their ivory between 2010 and 2012 — about one every 15 minutes. Elephants are threatened in formerly safe areas, and some of Africa’s most famous wildlife parks are littered with carcasses. Continue reading

Illegal international wildlife trade presents a related threat
By Bob Berwyn
FRISCO — Conservation advocates say some Mexican fishermen are ignoring a ban on gillnets in the northern Gulf of California, driving a porpoise species even closer to extinction.
Biologists say there are less than 100 vaquitas left in the area, and perhaps as few as 50, and despite Mexico’s stated intention to enforce the gillnet ban, Greenpeace observers reported this week that the now-illegal nets are still being widely used. Continue reading

Mosquito-free havens will start to disappear by mid-century, study warns
FRISCO — Island birds, including endangered species in the Hawai‘i archipelago, are facing a serious threat, as diseases carried by mosquitoes are due to expand into higher elevation safe zones.
With warming temperatures, mosquitoes will move farther upslope and increase in number, and mosquito-friendly temperatures are expected by mid-century, according to a new study by researchers with the U.S. Geological Survey and the University of Wisconsin-Madison. Future increases in rainfall will likely benefit the mosquitoes as well.
“We knew that temperature had significant effects on mosquitoes and malaria, but we were surprised that rainfall also played an important role,” said USGS Wisconsin scientist Michael Samuel. “Additional rainfall will favor mosquitoes as much as the temperature change.” Continue reading

Federal, state investigators concluded that the Utah killing was a case of bonafide misidentification

FRISCO — The coyote hunter who shot a protected gray wolf in Utah last year won’t face any criminal charges for killing an endangered species.
Investigators with the U.S. Fish and Wildlife Service, the Utah Division of Wildlife Resources and the U.S. Department of Justice found that the Utah resident was legally hunting coyotes near Beaver in late December when he mistook the collared female gray wolf for a coyote. Continue reading
