The way in which fragmentation changes and re-shapes these interactions can occur in many different forms. Most prey species have patches of land that are a refuge from their predators, allowing them the safety to reproduce and raise their young.
A fragmented state has several noncontiguous pieces of territory. Archipelagos such as Philippines, Indonesia, and Fiji are examples of fragmented states. [1] A prorupted or protruded has an extension that protrudes from the main territory. [3] Thailand is an example of a prorupted state. [1] A perforated completely surrounds another state ...
Population fragmentation causes inbreeding depression, which leads to a decrease in genetic variability in the species involved. [4] This decreases the fitness of the population for several reasons. First, inbreeding forces competition with relatives, which decreases the evolutionary fitness of the species. [ 4 ]
A wildlife corridor in Brazil.. A wildlife corridor, also known as a habitat corridor, or green corridor, [1] is a designated area that connects wildlife populations that have been separated by human activities or structures, such as development, roads, or land clearings.
Urbanization is causing humans to continuously fragment landscapes and thus increase the edge effect. This change in landscape ecology is proving to have consequences. [ 2 ] Generalist species, especially invasive ones, have been seen to benefit from this landscape change whilst specialist species are suffering. [ 3 ]
Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new ...
An example of the effects of abiotic factors on species distribution can be seen in drier areas, where most individuals of a species will gather around water sources, forming a clumped distribution. Researchers from the Arctic Ocean Diversity (ARCOD) project have documented rising numbers of warm-water crustaceans in the seas around Norway's ...
Biogeography now incorporates many different fields including but not limited to physical geography, geology, botany and plant biology, zoology, general biology, and modelling. A biogeographer's main focus is on how the environment and humans affect the distribution of species as well as other manifestations of Life such as species or genetic ...
