The drought gripping the Ottawa area isn't just burning grass and stunting corn crops. Mice are increasingly finding their way into homes and apartment buildings in search of water.

Polar bears have been rummaging through science camps at the top of Greenland's ice sheet far inland, where they were never expected, and Polar bears are coming into communities more often these days, says Kristin Laidre, a marine biologist at the University of Washington’s Polar Science Center, and an authority on polar bear populations in Greenland. “It’s happening all over the Arctic, and it’s something that’s only going to be an increasing problem as we continue to lose sea ice,” she says.

The tick is not native to the U.S., but was found in several locations in Westchester County.

New research published in PLOS ONE this week demonstrates dramatic positive benefits for native trees following rat removal at Palmyra Atoll, a magnificent National Wildlife Refuge and natural research laboratory located about 1000 miles south of Hawaii. For five native tree species, including Pisonia grandis, fewer than 150 seedlings were counted in the presence of rats, and more than 7700 seedlings were counted five years after rats were removed.

Deer ticks have made the jump from the mountains to city backyards, putting your dog at risk of contracting Lyme disease in the summer heat.

The report on Wood Buffalo National Park says industry, dams, climate change and natural cycles are sucking the lifeblood from the vast delta of northeastern Alberta's Peace and Athabasca rivers

Rocky Mountain spotted fever is an uncommon but potentially deadly tick-borne disease that's on the rise in the United States.

"If they were moving out of the Arctic, then you would see a lot of ponds draining... But thats not what we saw, we saw a lot of new ponds forming."

    Department of Fisheries and Land Resources theorizes why bears still around so late into the season

A rare sighting near the confluence of the Russian River.

Despite facing drastic increase in the number of ticks being reported in Niagara, the region’s acting medical officer of health says the chance of getting Lyme disease remain relatively low.

A respiratory pathogen once thought to only affect sheep and goats has been found in Alaska caribou and moose. The bacterium, called mycoplasma ovipneumoniae, or "Movi," has also been implicated in the death of an emaciated caribou from the Fortymile herd last month.

Michael Soltis’ death is the second fatal bear attack in the Anchorage municipality in two summers.

This most Northerly Bobcat (Lynx rufus) observation in the iNaturalist database marks the leading edge of the northward expansion of this species.

Mycoplasma ovipneumoniae ("Movi") is a respiratory bacterium that can cause disease in susceptible hosts. Previously thought to be host-restricted to sheep and goat species, scientists have identified Movi for the first time in healthy moose and caribou in Alaska; a bison in Montana; mule deer in New Mexico, and diseased white-tailed deer from the upper Midwest.

Adding to the concerns are stories of increasingly aggressive foxes in Marshall and other villages. It appears to be a strong year for the fox population, a state biologist said. Marshall is shooting stray dogs to protect village residents.

A dead hare was observed in Interior Alaska that was infested with a native species of tick. Wildlife officials are asking residents to keep an eye out for ticks on pets and for signs of tick infestation in large mammals, such as hair loss in moose.

By the early 1900s, trapping and poisoning had killed off most wolverines in the Lower 48, and today, fewer than 300 remain, mostly in Washington,...

‘Thousands’ perish amid calls for a state of emergency in the region, with fears anthrax vaccine is a cause of death.

Biologists are investigating a surprising connection between two animals that aren’t exactly well loved in parts of Southeast. Gustavus locals suspect wolves are picking off deer at a popular hunting spot on an island near the mainland.
