An Anchorage beekeeper has learned how to help his honeybee colonies survive to see spring, and he’s teaching others to do the same.
As Alaskan permafrost warms, hibernating arctic ground squirrels generate less heat, causing females to emerge from hibernation up to 10 days before their male counterparts – a mismatch that could have large, cascading ecological impacts. While reduced thermogenesis due to warming temperatures could allow the squirrels to conserve energy and, thus, increase winter survival, a shortened hibernation season could also increase the exposure of the animals to hungry predators, altering mortality rates, particularly for earlier emerging female squirrels. The phenological mismatch between the sexes may also disrupt reproductive rates. And over longer time scales, continued warming in the Arctic may lead to changes in male squirrel seasonal behaviors, say the authors.
“Warmer and wetter winters shorten the winter season and prolong the growing season, which give rise to new opportunities. Among other things, this includes higher annual yield with several harvests, along with the possibility to grow new, more productive crop varieties and species,” says Dr Sigridur Dalmannsdottir at NIBIO.
Climate change is affecting all aspects of our land, and also what flies in our sky. Bird migration is changing as average temperatures rise. So what does that mean for our bird species?
The number of dogs testing positive for tick-borne illnesses has nearly doubled this year, says a Nova Scotia veterinarian. Jeff Goodall, the owner and a veterinarian at Sunnyview Animal Care, said the problems go beyond Lyme disease. Anaplasmosis is also a concern. He said dogs have been testing positive for tick-borne illnesses throughout the winter.
Drivers in much of Alaska including Anchorage will have until May 15 to remove studded tires; those in southern areas will have until May 1.
