FRAGMENTATION ON OF HABITAT EFFECTS BIODIVERSITY

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…

Landscape modification and habitat fragmentation are key drivers of global species loss. Their effects may be understood by focusing on: (1) individual species and the processes threatening them, and (2) human-perceived landscape patterns and their…

Habitat loss and fragmentation are among the largest threats to amphibian populations. However, most studies have not provided clear insights into their population-level implications. There is a critical need to investigate the mechanisms that…

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…

Landscape fragmentation has often been seen as an only ecological problem. However, fragmentation also has a societal perspective, namely, in how humans perceive landscape fragmentation and in how landscape fragmentation potentially influences human…

Five hypotheses were tested to explain the pattern of galling insect species richness in four neotropical savanna physiognomies, 'canga', 'campo sujo', 'cerrado' s. st., and 'cerradao', that occur in Minas Gerais, southeastern Brazil. We found 125…

The objective of this study was to develop and apply a landscape ecology study method to a coastal promontory, aiming to understand the processes that involve its formation and its maintenance. This research related the spatial structure of the…

In their review of the recent ''explosion of spatially explicit theory'' in ecology Kareiva and Wennergren (1995) suggest a number of emerging principles for species conservation. One of these principles is that how habitats are arranged in space…

The effects of woodlot size and isolation, in relation to habitat fragmentation, on the distribution of the red squirrel were studied. In The Netherlands, 50 woodlots (0.55 - 13.78 ha) were surveyed in an agricultural landscape for the presence of…

Studies comparing dispersal in fragmented versus unfragmented landscapes show that habitat fragmentation alters the dispersal behavior of many species. We used two complementary approaches to explore Florida Scrub-Jay (Aphelocoma coerulescens)…
