Effects 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...

Habitat fragmentation and biodiversity collapse in neutral communities

Models of habitat fragmentation have mainly explored the effects on a few-species ecologies or on a hierarchical community of competitors. These models reveal that, under different conditions, ecosystem response can involve sharp changes when some given thresholds are reached. However, perturbations, recruitment limitation and other causes may prevent competitive hierarchies from actually opera...

The Effects of Habitat Fragmentation and Connectivity on Plant Disease

JOHNSON, BRENDA LYNN. The Effects of Habitat Fragmentation and Connectivity on Plant Disease. (Under the direction of Nick M. Haddad.) Within a large-scale habitat corridor experiment, I performed both experimental and observational studies to determine the effects of habitat fragmentation, habitat edge, and patch connectivity on the movement and incidence of fungal plant diseases. Increased sp...
