Global patterns of tropical forest fragmentation

Nature, 2018
Remote sensing enables the quantification of tropical deforestation with high spatial resolution. This in-depth mapping has led to substantial advances in the analysis of continent-wide fragmentation of tropical forests. Here we identified approximately 130 million forest fragments in three continents that show surprisingly similar power-law size and ...

The Paradox of Forest Fragmentation Genetics

Conservation Biology, 2008
Abstract:  Theory predicts widespread loss of genetic diversity from drift and inbreeding in trees subjected to habitat fragmentation, yet empirical support of this theory is scarce. We argue that population genetics theory may be misapplied in light of ecological realities that, when recognized, require ...

Forest Fragments and Fragmentation

Forest fragmentation is the process of splitting large, continuous areas of forest into increasingly small and separate patches. This process typically reduces both the area of continuous forest and creates fragments that can become isolated and impacted by the surrounding environment. Key drivers of forest fragmentation include agricultural expansion,

Climbers in forest fragments in Togo.

2005
AbstractTogo is located in the Dahomey Gap which separates the West African tropical moist forest from that of Central Africa. Farmland, fallow lands and savannahs essentially characterize the predominantly open landscape. In forest fragments in southern Togo, climbing plants represent one third of the total number of species.

Forest fragmentation: another perspective

Trends in Ecology & Evolution, 1998
In his recent (and very favorable) review of our edited book, Tropical Forest Remnants[1xLeigh, E.G Jr. Trends Ecol. Evol. 1997; 12: 414Abstract | Full Text PDFSee all References][1], Egbert Leigh raised some issues of general interest to those who study the ecology of fragmented habitats.

Forest fragmentation and avian nest predation in forested landscapes

Oecologia, 1988
The size of forest fragments, the use of land bordering fragments, and the distance of nests from an edge all affect the frequency of predation upon bird nests in Maine (USA), an area where the forest has been fragmented by roads, but not significantly reduced in area.

Insects in fragmented forests: a functional approach

Trends in Ecology & Evolution, 1996
Insects are highly susceptible to the adverse effects of forest fragmentation. It is now beyond any doubt that fragmentation-induced changes in abundance and species richness occur in many insect groups. However, the study of insects in fragmented forests is still in its infancy and lacks real direction.

Fragmented Forest

1992
Abstract Scattered throughout southeastern Brazil, from Bahia in the north to Sao Paulo in the south, and inland into Minas Gerais, are isolated stands of what remains of the Brazilian Atlantic forest. It once carpeted the chain of mountains running along the eastern coast of Brazil from the states of Rio Grande do Soul to Rio Grande ...
