Matrix composition mediates effects of habitat fragmentation: a modelling study
نویسندگان
چکیده
Abstract Context Habitat loss has clear negative effects on biodiversity, but whether fragmentation per se (FPS), excluding habitat does is debatable. A contribution to this debate may be that many studies tend use landscapes of fragmented focal-habitat and a single vastly different species-poor intervening land cover (the matrix). Objectives How matrix composition influence the effect FPS biodiversity?. Methods Using an individual-based model investigate configurations relationship between biodiversity focal-habitat. We manipulated number quality types in matrix, their similarity Results Extremely caused order magnitude stronger alpha- gamma-diversity beta-diversity decline. Low led high gamma-diversity. Increasing dramatic decline low diversity. In contrast with more similar had lower diversity under declining little increasing FPS. Having few general compared larger numbers. Conclusions The change depending recommend should consider greater variety help assess which cases not have impact allow better predictions impacts fragmentation. show importance having improving hospitability for species dependent

Habitat fragmentation and reproductive success: a structural equation modelling approach.
1. There is great interest on the effects of habitat fragmentation, whereby habitat is lost and the spatial configuration of remaining habitat patches is altered, on individual breeding performance. However, we still lack consensus of how this important process affects reproductive success, and whether its effects are mainly due to reduced fecundity or nestling survival. 2. The main reason for ...

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...
