Document Summary
Causes and consequences of dispersal in plants + animals. Dispersal: movement of individual away from pop where they were bon to diff location where they will settle + reproduct. Natal: first movement ever from its birth site to the site it first attempts to reproduction. Adult dispersal: changing location in space after reaching repro maturity and moving from one habitat patch to another. Relocation to a new site = adaptive trait. Active: movement of the entire organism on its own (adult + juvenile animals) Vary among species depending on factors like social structure. Ex) social systems that rely on only one adult male for r force younger males to disperse. Density-dependent process where magnitude depends on a local pop size, resource competition, and habitat quality/size. Local pop conditions may affect juvenile + adult diff, so vary between age groups. Highly vagile = most efficient at active dispersal= greatest cap for long distance dispersal.
