Document Summary
Forest fragments have a long history of study - in particular how there is a difference between the quality of habitat between interior habitat and habitat closer to the edge. Abiotic factors: there is differential movement of solar radiation, temperature, humidity, moisture, and wind between interior and edge habitat. Edge habitats often become intermediate between the two adjacent habitats (e. g. between forest and field, the forest edges become hotter and drier with solar radiation than the interior) Access: when resources are spatially separated and edge provides access to both resources. Species interactions: many incidences of increased nest predation for birds nesting in edge habitats. Population growth is defined as the change in the number of individuals during some period of time. This is calculated using demographic data; population growth rate = birth rate death rate + immigration emigration. D is the number of deaths, i is the number of immigrants, and e is the number of emigrants.
