Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. [2] Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment [3] (suspected of being one of the ...
The SLOSS debate was a debate in ecology and conservation biology during the 1970's and 1980's as to whether a s ingle l arge o r s everal s mall (SLOSS) reserves were a superior means of conserving biodiversity in a fragmented habitat. Since its inception, multiple alternate theories have been proposed. There have been applications of the ...
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
Habitat destruction. Map of the world's biodiversity hot spots, all of which are heavily threatened by habitat loss and degradation. Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or ...
In ecology, edge effects are changes in population or community structures that occur at the boundary of two or more habitats. [ 1 ] Areas with small habitat fragments exhibit especially pronounced edge effects that may extend throughout the range. As the edge effects increase, the boundary habitat allows for greater biodiversity.
the movement of a population away from other individuals of that species, such as the natural introduction of wolves and moose on Isle Royale, geologic processes, such as landslides or volcanoes, dividing a habitat. rising sea levels separating islands from what was once a common landmass, global warming, especially when coupled with mountains ...
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 ...
Canopy cover surrounding Madison, Wisconsin. Landscape ecology is the science of studying and improving relationships between ecological processes in the environment and particular ecosystems. This is done within a variety of landscape scales, development spatial patterns, and organizational levels of research and policy. [ 1 ][ 2 ][ 3 ...
