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 ...
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 ]
Often, the changes are detrimental to both the size of the habitat and to species. Examples of human impacts include: Introduction of invasives/exotics; Higher severity and frequency of fires; Companion animals (pets) acting as predators and competitors; Trails; Pollution, erosion; Loss of foraging habitats; Habitat fragmentation; Deforestation ...
Habitat degradation, fragmentation, and pollution are aspects of habitat destruction caused by humans that do not necessarily involve over destruction of habitat, yet result in habitat collapse. Desertification , deforestation , and coral reef degradation are specific types of habitat destruction for those areas ( deserts , forests , coral reefs ).
The study of habitat fragmentation found its roots early, with Aldo Leopold’s ideas on edge effect and Robert MacArthur and E. O. Wilson’s studies and models of island biogeography laying a foundation for the field (Laurance and Bierregaard 1997). These concepts offer potential applicable and hypothetico-deductive value for the study of ...
Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, [60] introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation.
Habitat fragmentation can be caused by roads. When humans start to cut down the trees for logging, secondary roads are created that will go unused after its primary use. Once abandoned, the plants of the rainforest will find it difficult to grow back in that area. [37] Forest fragmentation also opens the path for illegal hunting.
