Scientists suspect that warming air and rivers, as well as smaller winter snowpack, is endangering western trout. But on a ranch in Montana, methods to protect trout from the effects of cattle ranching are helping the trout become more resilient to the inevitable change in their environment.
A study of DNA extracted from wolf and dog fossils suggests that ancient wolf populations in Europe are the direct ancestors of most modern-day domestic dogs. The study suggests wolves became dogs between 18,800 and 32,100 years ago, before the start of agriculture.
In the northern Rockies of Montana, wildlife is a part of daily conversation. Fishing alone generates $250 million a year, and the pursuit of trout brings in most of that money. But record droughts and declining snowpack mean streams are becoming less habitable for this revered fish.
It's white tailed deer season for millions of hunters across the country. Most will tromp into fields and forests stalking their prey. But others will set up in cities and suburbs. Urban hunts are spreading across the country as a way to control the animal's booming population. But not everyone's happy having camouflaged hunters perched on tree stands in their neighborhoods.
Parts of the U.S. and Canada have seen a rapid decline in moose populations that may be linked to climate change. And, scientists and hunters warn, those declines have often been accompanied by a surge of infestations of the winter tick.
There's a curious twist in the contentious debate over feeding antibiotics to animals in order to make them grow faster. Evidence suggests using antibiotics for growth promotion, at least among pigs, doesn't even make economic sense. But some pork producers don't believe it.
Is that a left wag or a right wag? Scientists have previously shown that dogs tend to wag their tails to their right side when they see something friendly, like their owners. But a new study shows that other dogs can actually pick up on these emotional cues.
