Habitat fragmentation effects on trophic processes of insect-plant food webs.
Habitat fragmentation is the transformation of once-extensive landscapes into smaller isolated remnants surrounded by new types of habitat. There is ample evidence of impoverished biodiversity as a consequence of habitat fragmentation, but its most profound effects may actually result from functional changes in ecological processes such as trophic interactions. We studied the trophic processes ...

متن کاملEffects of Habitat Fragmentation on Biodiversity
■ Abstract The literature on effects of habitat fragmentation on biodiversity is huge. It is also very diverse, with different authors measuring fragmentation in different ways and, as a consequence, drawing different conclusions regarding both the magnitude and direction of its effects. Habitat fragmentation is usually defined as a landscape-scale process involving both habitat loss and the br...
متن کاملEffects of Grassland Habitat and Plant Nutrients on Soybean Aphid and Natural Enemy Populations
The soybean aphid Aphis glycines Matsumura (Hemiptera: Aphididae) is an invasive economic pest of soybean (Glycine max[L.] Merrill) in the United States. Research has shown the endemic natural enemy community in the United States is capable of suppressing A. glycines below EILs, but this biological control is inconsistent, especially in simple agricultural landscapes. In the course of a 3-yr pr...
متن کاملImplications of Large - Scale Habitat Fragmentation
The field of landscape ecology is an emerging complex area of study encompassing numerous concepts and principles. Landscapes are intricate systems and must remain balanced if ecosystem collapse is to be avoided. However, habitat fragmentation in landscapes of differing characteristics is threatening to upset such interconnectedness. It is the purpose of this investigation to explore the theory...
