The Northeast, which has warmed faster than the rest of the country, saw the biggest jump in mosquito days. Look up how mosquito season has changed in your town.
An Anchorage beekeeper has learned how to help his honeybee colonies survive to see spring, and he’s teaching others to do the same.
In Southeast Alaska, and across the state, climate change is bringing more rainfall, less winter snowfall and hotter temperatures. According to the project’s lead researcher Alex McCarrel, those changes disrupt berry development because a berry plant’s life cycle is precisely tuned to its environment.
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.
