Forest habitat fragmentation caused by agriculture and residential development have long been recognized as impediments to the ability of plants to geographically track climate change. [171] Several additional human stressors are now also recognized as lessening the ability of trees to adapt to climate change by "migrating poleward."
Increasing and widespread habitat loss and fragmentation, along with the SLOSS debate, have led to the questions the BDFFP originally sought to answer. Overall, Lovejoy’s goal in establishing the project was to determine necessary reserve size and placement for successful habitat and species conservation, hence the original name of the project.
Habitat fragmentation describes spatial discontinuities in a biological system, where ecosystems are broken up into smaller parts through land-use changes (e.g. agriculture) and natural disturbance. This both reduces the size of the population and increases the degree of isolation.
Reduced fragment area, increased isolation, and increased edge initiate changes that percolate through all ecosystems. Habitat fragmentation is able to formulate persistent outcomes which can also become unexpected such as an abundance of some species and the pattern that long temporal scales are required to discern many strong system responses ...
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 ]
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 ).
Path of the Panther played a role in raising awareness about habitat fragmentation and the need to protect the Florida panther’s dwindling population. [21] The documentary was part of a broader impact media project supported by the Florida Wildlife Corridor Foundation and the National Geographic Society.
Habitat loss, fragmentation and degradation; [4] for example habitat fragmentation for commercial and agricultural uses (specifically monoculture farming) [5] Land use intensification (and ensuing land loss/habitat loss); a significant factor in loss of ecological services due to direct effects as well as biodiversity loss [6]
