Document Summary
Environmental management: understanding autecology (dynamics of species population and how they interact with the envr) Island biogeography is the study of the distribution of species or ecosystem(s) over a geographic area over a geological time. It attempts to explain how isolation and habitat size affects probable mixes of species through species influx/migration/extinction (ex. Debate over what is better: a large habitat, or smaller, fragmented habitats. Succession is the process by which ecological communities undergo changes following a disturbance. Primary succession (what happens from a massively disturbed area, like a post-tsunami ecosystem. Secondary succession is something that happens recurrently, or on previously existing substrate, from smaller disturbances. Example: fireweed jack pine spruce tree. Getting more and more fire vulnerable (disaster complex) Often, areas of freshwater eventually dry out to become woodland. Over this time, marshes and swamps will succeed each other. Wicken fen has been flooded many times before (once part of the ocean).
