Bio 3130 Lecture 13
Case Study: why Canadians’ climate concerns don’t always line up with the evidence
- earth is hotter than it has been in any of our lifetimes but Canadians are less
concerned about climate change than a decade ago
- economic anxieties rank top, climate change still up there
Climate Change and Conservation
- to date: only 2 extinctions attributable to climate change: golden toad and
harlequin frog
- but massive shifts for some species and systems associated with warming
- buffering: the ability to track the changing climate in time and location
- Management: anticipate the changes and assist with the buffering
- Past emphasis: a focus on local issues (patch size, population size, species)
- Climate: the new paradigm
- Demands a regional scale strategy for conservation:
o 1. Reserves that allow for range shifts (corridors, gradients)
o 2. Reserves that capture population variability
individuals are not genetically identical, in their responses to
climate or to climate change
o 3. Reduce non-climatic stressors that hamper adjustments and
movements (ex. Invasion)
o Carbon credits, biofuels, and soil carbon
Key premise: protecting natural areas and biodiversity can
both help reduce levels of atmospheric CO2
Soil Carbon in Shoots and Roots
- 20-30% of carbon in soils
- protected areas in Canada play significant role in carbon sequestration and
its value to Canadians
o density of carbon in national parks very high and can range from $72-
78 billion
o trying to change the way society views carbon/nature
The Iceberg Phenomenon
- up to 90% of all biological activity in terrestrial ecosystems can be
