Document Summary
In purple it"s not found even though that area is optimal for them to live in (this is due to competition (bio fac 1) b/w this barnacle and another one: ability to disperse (bio fac 2) In order to live in that area, they have to be able to get inn that area. Individuals respond to environmental variation through acclimatization (acclimation: acclimatization: shift in optimal tolerance range/limits. Ecotypes = locally-adapted populations w/in a species an evolutionary component: not talking about diff species. If the populations separated from each other and selection pressures are diff or intense, can get evolution of new species: this bud feeds on adenostoma sp. Acclimation/acclimatization and adaptation require investment of energy and resources. Reduce solar radiation: organisms can heat up due to solar radiation so move into sun or move into shade, 2. increase convention, turn off fan or get out of wind, 3. Increase conduction: b) energy balance by plants.
