Disruption #1: Habitat Destruction/Loss/Fragmentation/Degradation Deforestation in tropical areas is the greatest eliminator of species. Globally, temperate biomes have been affected more by habitat loss and degradation than have tropical biomes because of widespread economic development in temperate countries over the past 200 years. Island species -- many of them endemic species found nowhere else on earth -- are especially vulnerable to extinction when their habitats are destroyed, degraded, or fragmented. Any habitat surrounded by a different one can be viewed as a habitat island for most of the species that live there. Most national parks and other nature reserves are habitat islands, many of them encircled by potentially damaging logging, mining, energy extraction, and industrial activities. Habitat fragmentation -- by roads, logging, agriculture, and urban development -- Occurs when a large area of habitat is reduced and divided into smaller, isolated patches, or habitat islands. This process can decrease tree populations in forests, block migration routes, and divide populations of a species into smaller and more isolated groups that are more vulnerable to predators, competitor species, disease, and catastrophic events such as storms and fires. Also, it creates barriers that limit the abilities of some species to disperse and colonize new areas, get enough to eat, and to find mates. Adapted from Living in the Environment textbook by Miller 1A) Which biomes have been most affected by habitat destruction and why? 1B) What human activities cause habitat fragmentation? 1C) Explain how habitat fragmentation affects biodiversity.

Disruption #1: Habitat Destruction/Loss/Fragmentation/Degradation Deforestation in tropical areas is the greatest eliminator of species. Globally, temperate biomes have been affected more by habitat loss and degradation than have tropical biomes because of widespread economic development in temperate countries over the past 200 years. Island species -- many of them endemic species found nowhere else on earth -- are especially vulnerable to extinction when their habitats are destroyed, degraded, or fragmented. Any habitat surrounded by a different one can be viewed as a habitat island for most of the species that live there. Most national parks and other nature reserves are habitat islands, many of them encircled by potentially damaging logging, mining, energy extraction, and industrial activities. Habitat fragmentation -- by roads, logging, agriculture, and urban development -- OCcurs when a large area of habitat is reduced and divided into smaller, isolated patches, or habitat islands. This process can decrease tree populations in forests, block migration routes, and divide populations of a species into smaller and more isolated groups that are more vulnerable to predators, competitor species, disease, and catastrophic events such as storms and fires.
