Synergistic impacts of habitat loss and fragmentation on model ecosystems
Habitat loss and fragmentation are major threats to biodiversity, yet separating their effects is challenging. We use a multi-trophic, trait-based, and spatially explicit general ecosystem model to examine the independent and synergistic effects of these processes on ecosystem structure. We manipulated habitat by removing plant biomass in varying spatial extents, intensities, and configurations...
متن کاملHabitat Loss and Fragmentation
Glossary Cover type A term used by the geographers for a type of mapped feature (e.g., forest, freshwater, or grassland). The dominant natural cover type in a landscape is often used to approximate habitat. Fragmentation per se The breaking apart of habitat while keeping habitat amount constant. Habitat The place where an organism normally lives. Habitat fragmentation The breaking apart of habi...
متن کاملHabitat fragmentation and its lasting impact on Earth’s ecosystems
We conducted an analysis of global forest cover to reveal that 70% of remaining forest is within 1 km of the forest's edge, subject to the degrading effects of fragmentation. A synthesis of fragmentation experiments spanning multiple biomes and scales, five continents, and 35 years demonstrates that habitat fragmentation reduces biodiversity by 13 to 75% and impairs key ecosystem functions by d...
متن کاملHabitat fragmentation, species loss, and biological control.
Fragmentation of habitats in the agricultural landscape is a major threat to biological diversity, which is greatly determined by insects. Isolation of habitat fragments resulted in decreased numbers of species as well as reduced effects of natural enemies. Manually established islands of red clover were colonized by most available herbivore species but few parasitoid species. Thus, herbivores ...
متن کاملEffects of Habitat Loss and Fragmentation on Population Dynamics
We used a spatially explicit population model that was generalized to produce nine ecological profiles of long-lived species with stable home ranges and natal dispersal to investigate the effects of habitat loss and fragmentation on population dynamics. We simulated population dynamics in landscapes composed of three habitat types (good-quality habitat ranging from 10–25%, poor-quality habitat ...
