Arctic plants and insects


This 2014 video from Canada says about itself:

Jennifer Doubt, botanist and curator at the Canadian Museum of Nature, talks about discovering Arctic plants.

She explores terrain in Iqaluit, Nunavut, and Greenland during a Students on Ice Arctic expedition.

Expedition Arctic is an educational web site for youth. It was created by the Canadian Museum of Nature, Students on Ice and Habitat Seven, in collaboration with the Virtual Museum of Canada.

Insect pollination is as important to Arctic plants as it is to plants further south. When flowers abound, the plants have to compete for pollinators. Researchers at the University of Helsinki reveal that higher temperatures cause the flowering periods of different plant species to pile up in time. As a consequence, climate change may affect the competitive relationships of plants. The most attractive plant species steal the majority of pollinators, making other plants flowering at the same time suffer from poorer pollination: here.

Through a unique research collaboration, researchers at the University of Helsinki have exposed major changes taking place in the insect communities of the Arctic. Their study reveals how climate change is affecting small but important predators of other insects, i.e. parasitoids: here.
