Long term studies from different parts of
the world have already started to detect ecological changes, such
as alteration in breeding ranges, flowering dates, breeding dates
and migration, all attributed to climate changes. However, in
the Arctic, evidences of such ecological impacts are still scarce,
mainly due to the fact that only few studies have enough long-term
data sets to address these questions. Nevertheless, the simple
ecological communities of the Arctic may suffer greatly from global
warming, especially considering that the effects of climate change
are expected to be particularly acute in this region.
We think that the data accumulated on Bylot Island over the past
decade may help to elucidate some of the effects of climate changes
on ecological variables, and are thus of utmost importance in
predicting the consequences of future climate changes. The primary
step that we took to investigate these questions was to identify
temporal trends in the climate of the Bylot Island region.
