Document Summary
Lecture 6 temperature constraints: microclimate localised short time climate eg. going to shade on a hot day, macroclimate local weather reports, long term eg. precipitation rate, climate of. Edmonton, wind pattern: macroclimate + local landscape = microclimate, landscape features that influence microclimate. Northern aspects face north, shaded in north hemisphere. Southern aspects sace south, shaded in south hemisphere. Colour: darker colour absorb more light warmer low albedo. Boulders and burrows under rocks: warmer than surrounding; burrows experience fewer changes than surrounding, more moderate temperature. In deserts, most animals live in burrows because burrows are less affected by the changing day and night temperature. Topography: aquatic environments are much more resistant to temperature changes. Water has high specific heat energy (3000 times more than air) Heat is absorbed by water as it evaporates. Organisms perform best within a narrow range of conditions.
