Document Summary
Ecosystems: climate effects on ecosystems, plants and animals can grow, survive, and reproduce only in specific climate conditions, can cause disruption to species, non-climate effects on ecosystems, many non-climate driving forces affect species: Individual butterflies don"t move: just species in colder locations have been more successful: quino checkerspot butterfly, quino checkerspot: subspecies od edith"s checkerspot, endangered, biggest threat is urban development. First species for which climate change is officially listed as a threat and factor that must be considered for recovery: recovery would be easiest in southern range of species because less development is occurring there. In addition to moving in location (higher latitudes or higher elevation), species can shift in time too. Spring is happening 5-15 days earlier: timing events in nature: Leaf coloring, leaf fall: bird migration, amphibian chorusing (calling to start mating season, appearance/emergence of butterflies, timing of biological activity.
