The dispersal of the species involves organisms entering and exiting patches to inhabit another patch. Dispersal may affect the distribution of the organism or the overall fitness of the population thus harming the species richness or possible increasing the richness (Ricklefs 2008)....   [tags: Environmental Issues]
