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 ...
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 ...
The Project is located near Manaus. The Biological Dynamics of Forest Fragments Project (BDFFP; or Projeto Dinâmica Biológica de Fragmentos Florestais, PDBFF, in Portuguese) is a large-scale ecological experiment looking at the effects of habitat fragmentation on tropical rainforest.
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 study has found greater pollination and increased fruit production of M. insignis in unfragmented forests verses fragmented forests. [59] As for an example of an antagonistic relationship of nest predation, a study found that there is no increase in nest predation on fragmented forests - thus not supporting the edge effect hypothesis. [60]
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 ]
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 ...
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.
