Document Summary
Biological consequences of physical factors: spatial distribution of organisms (from the biome perspective, primary productivity, biodiversity. Spatial distribution of organisms: at very broad scales: biomes. Many ways of classifying biomes: e. g. Canada (i. e. ecozones, ecoregions, ecodistricts), wwf ecoregions, etc: at smaller scales, species associated with specific habitat characteristics. Biome mixedwood plains: the smallest ecozone in. Canada (~115,000km2), it has the highest biological diversity, faces the most extreme threats, and has the highest population densities. Typical vegetation: mesic habitats (not too dry, not too humid) Higher diversity especially on south- facing slopes: e. g. eardley escarpment in the gatineau, niagara escarpment. Forestry: for construction, royal navy masts in the 19th century (pine, selective cut: no large forests remain in this ecozone. South march highlands, 20 min west of downtown ottawa, voted #1 on list of great places in. Mixed-wood plain: biodiversity hotspot in canada, but also a hotspot of every kind of human activity!
