Document Summary
Bio220 lecture 12: climate effects on organisms, phenology, and interactions. Sometimes changes in the environment happens slow enough for migration to occur in some species. If changes are developing too fast, animals will not be able to fully adapt and evolve. Optimal elevation is higher than previous years. Some kind of globally coherent signal in the distributions. Everything seems to be shifting to the poles. Areas that warm faster, more altitudinal and latitudinal changes of species in their locations. Assume that where species now, is where they are most suitable. Measure the ecological conditions in that location create an envelop of suitability . Gcm is used to predict how ecological conditions will change. Estimate where conditions will be suitable in the future. Above all, we can figure out how far species will have to shift. Pika"s are known for their adaptations in high, cold, mountains. Modeling species loss from sky islands due to climate change.
