Rapid industrialization, urbanization, and growth in population have resulted in massive deforestation and consequential habitat loss around the world. Among the potential regional effects of habitat loss on diversity loss beyond simply losing the habitats of endemic species include: (1) reductions in the total numbers of ponds left in the landscape, (2) reductions in the total surface area of ponds left in the landscape or (3) reductions in the habitat connectivity (and likely dispersal) among the ponds remaining in the landscape. Students will be presented with examples of each and what happens when diversity is absent. Biodiversity loss can have indirect effects on human well-being as well.
By disrupting ecosystem function, biodiversity loss leads to ecosystems that are less resilient, more vulnerable to shocks and disturbances, and less able to supply humans with needed services. Threats to biodiversity - overexploitation, extinction, habitat loss, invasive species, disrupting connectivity of ecosystems; Biodiversity - Bill Nye ... 12 Biodiversity.ppt (5503k) distinguish between habitat loss and habitat fragmentation per se, i.e., the breaking apart of habitat after controlling for habitat loss.

Destruction of Habitat The destruction of habitat, such as the clearing of tropical rain forests, has a direct impact on global biodiversity. LOSS OF BIODIVERSITY ' Habitat loss and degradation ' Habitat loss and degradation create the biggest single source of pressure on biodiversity worldwide ' For terrestrial ecosystems, habitat loss is largely accounted for by conversion of wild lands to agriculture, which now accounts for some 30% of land globally ' In some areas, it has recently been partly driven by the demand for biofuels 14 Habitat loss refers to the disappearance of natural environments that are home to particular plants and animals. it is the most significant cause of biodiversity loss globally.
