The project was initiated in 1979 by Thomas Lovejoy to investigate the SLOSS debate. Initially named the Minimum Critical Size of Ecosystems Project, [1] the project created forest fragments of sizes 1 hectare (2 acres), 10 hectares (25 acres), and 100 hectares (247 acres). Data were collected prior to the creation of the fragments and studies ...
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.

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 ]
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 ...
Ongoing responses to PADDD include Project Finance for Permanence (PFP), which is an innovative method to secure permanent funding for conservation areas. [20] The largest PFP, Amazon Region Protected Areas (ARPA), permanently financed conservation initiatives in 15 percent of the Brazilian Amazon.
