Government officially declares Eastern puma extinct


TRAVERSE CITY, Mich. (AP) — Federal officials have declared the Eastern puma extinct, 80 years after the last confirmed sighting of a graceful wildcat that once roamed widely from the Upper Midwest to the Atlantic seaboard.
The U.S. Fish and Wildlife Service announced this week it was removing the animal from the endangered species list. The move completes a process started in 2015, when the agency proposed dropping federal protections for the Eastern puma, which is also known as the cougar, mountain lion and catamount. Its territory ranged from Michigan and southern Ontario to New England, the Carolinas and Tennessee.
The action is largely a formality, as the last known member of the population was seen in 1938. But it was necessary because a species can be listed as endangered only if it’s believed to still exist.
“Given the period of time that has passed without verification of even a single Eastern puma, the Service concludes that the last remaining members of this subspecies perished decades ago,” the Fish and Wildlife Service said in a Federal Register notice.
Some pumas have turned up occasionally in Eastern states in recent decades, the agency said. But genetic and forensic testing shows they had been released or escaped from captivity, or had wandered in from the West.
The puma once was the most widely distributed land mammal in the Western Hemisphere but has disappeared from two-thirds of its original range since European settlement began, the agency said.
Its decline resulted from poisoning, trapping, hunting and bounty programs aimed at wiping out the species, along with loss of forested habitat and a sharp drop-off in the 1800s of whitetail deer, the puma’s primary food source.
The Florida panther, an endangered separate sub-species, is the only remaining breeding population east of the Mississippi.
The federal agency said it considered feedback from scientists and the general public before making the decision to declare the Eastern puma extinct.
Although historically classified as a distinct sub-species, recent evidence suggests the Eastern puma may have been the genetic equal of other U.S. puma or cougar populations, said Michael Robinson of the Center for Biological Diversity, an advocacy group. The Fish and Wildlife Service said further analysis is needed to determine whether that’s true.
Either way, Robinson said, declaring the Eastern puma extinct removes a barrier to transporting wildcats from the West in hopes of rebuilding populations in Eastern and Midwestern states.
“It provides a green light for discussion and hopefully action,” Robinson said. “We need large carnivores like cougars to keep the wild food web healthy. Cougars would curb deer overpopulation and tick-borne diseases that threaten human health.”
It would be up to the states to initiate such efforts, Fish and Wildlife Service spokeswoman Meagan Racey said. Many places in eastern North America probably could support pumas, which are adaptable and can live in grasslands, forests, mountains and swamps, she said.
“Wild cougar populations in the West have been expanding their range eastward in the last two decades,” Racey said. “While individual cougars have been confirmed throughout the Midwest, evidence of wild cougars dispersing farther east is extremely rare.”
A young male cougar traveled about 2,000 miles from South Dakota through Minnesota, Wisconsin and New York before dying on a Connecticut highway in 2011. A cougar of unknown origin was killed in Kentucky in 2014.

Extinct bat rediscovered after 120 years without a sighting

In 1890, an Italian scientist discovered a species of bat in Papua New Guinea that hasn't been spotted since then. It was thought the species had gone extinct because there had been no sightings in 120 years. However, student researchers from the University of Queensland Catherine Hughes and Julie Broken-Brow rediscovered the bat species during a field expedition in the Abau coastal district in Papua New Guinea's Central Province. Welcome back, Pharotis imogene!

The researchers only had their bat traps up for two nights in this location, which means the capture was an extraordinarily lucky one. The specimen caught was euthanized and loaned to the Australian Museum in Sydney, where it was identified as being the long-lost species, the common name being the New Guinea big-eared bat. According to The Conversation, "The New Guinea big-eared bat, like the rest of the genera Pharotis and Nyctophilus, is distinguished by a combination of two features: large ears and a simple “nose-leaf” structure immediately behind the nostrils. Collectively, the group of species is known as long-eared (or big-eared) bats. P. imogene has larger ears than most."

Learning more about the entire species through this recently caught specimen will help researchers in identifying species in the field, and also learn more about what conservation measures are needed to protect this and other bat species in Papua New Guinea. The New Guinea big-eared bat is listed as critically endangered (possibly extinct) by IUCN, as well as making it to the top 100 of the world’s most unique and endangered mammals.

"Further studies need to be done to establish whether the New Guinea big-eared bat is one of a small number of mammal species endemic to the south-eastern peninsula region, or if it occurs more widely," Dr Leung told Science World Report. "Many of the coastal lowland habitats throughout Papua New Guinea are among the most threatened in the country due to clearing for logging and agriculture, and more field surveys of local bat populations could assess the conservation status of the species and inform future strategies to ensure their preservation."

As Dr. Leung and Broken-Brow note in The Conversation, "PNG is one of the world’s biodiversity hotspots. The country accounts for about 7 percent of the world’s species diversity, with about 276 known mammal species, 314 freshwater fish, 641 amphibian and reptile species, 740 birds, and many more. According to the World Wildlife Fund, between 1998 and 2008, 1060 new species were discovered, including a blue-eyed spotted cuscus, a 2.5 metre freshwater shark, and a giant bent-toed gecko." And now, the rediscovery of a bat species not sighted in 120 years. The new capture location means the researchers know where to start looking to gather more data on this and other bat species, and sites for further ecological studies that can help in conservation efforts.
