The Effect of Habitat Fragmentation on Population ...

One of the greatest challenges in conservation biology is assessing the impacts of habitat loss and fragmentation on population viability and abundance (Brigham, & Schwartz 2003). Loss of suitable habitat not only reduces the population's available resources, but also can increase habitat fragmentation.

Fish and Wildlife Service

Habitat is a combination of environmental factors that provides food, water, cover and space that a living thing needs to survive and reproduce. Habitat types include: coastal and estuarine, rivers and streams, lakes and ponds, wetlands, riparian areas, deserts, grasslands/prairie, forests, coral reefs, marine, perennial snow and ice, and urban.

Assessing Habitat Fragmentation Effects on Primates: The ...

We advocate that habitat fragmentation is a landscape-scale process that involves both loss and the breaking apart of habitat. Hence, independently analyzing both effects is necessary to assess the effects of the breaking apart of habitat while controlling for habitat loss (fragmentation per se).

Effects of Habitat Fragmentation on Biodiversity | Annual ...

Habitat fragmentation per se has much weaker effects on biodiversity that are at least as likely to be positive as negative. Therefore, to correctly interpret the influence of habitat fragmentation on biodiversity, the effects of these two components of fragmentation must be measured independently.

Despite the critical threat of habitat fragmentation, global patterns of fragmentation and its relationship to extinction risk have not been quantified for any major taxon. We developed high-resolution models that provide a global assessment of the degree of habitat fragmentation impacting the world's terrestrial mammals. Results demonstrate that mammals with more fragmentation are at ...

The large-scale movement patterns and extensive connectivity of the system indicate that habitat fragmentation and changes in water flow will adversely affect both species, but most strongly the trout. The reduction in water flow over large and productive stretches of the river might select for less migratory genotypes in both species.

Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (), causing population fragmentation and ecosystem decay.Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation),and human activity such as land .
