Our local news ran a piece last night about the pending encroachment of all sorts of pests like fleas, ticks, etc. that are going to cause trouble for our caribou, moose and other wildlife. Not to mention the methane and CO2 released from the melting permafrost.

But one scientist who presented research this week at the Alaska Forum on the Environment, threats posed by climate change are much more dangerous to entire ecosystems than to just one species.
Doctor Eric Hoberg of the Department of Agriculture says that change will be brought on by the arrival of parasites like ticks, fleas and worms -- pests that could spread through Alaska's wildlife population.
"We think that parasites, pathogens, these disease-causing organisms have the potential to have a very dramatic affect on things like caribou, sheep, wild sheep, moose, musk oxen," he said.

"So as temperatures increase, the developmental rates are faster and faster so that the generation time, the time between infection of the final host is shortened," he said.
It all could happen so quickly, scientists here believe, that Alaska's moose, caribou and other animals that could become infected will not have time to develop immunities.
"The general feeling in the broader community is that this is outside of the capacity for populations to be resilient or those species to be able to adapt effectively," Hoberg said.
