AbstractForest fragmentation is a pervasive threat to forest ecosystems throughout the world. Reduced overall numbers of individuals, decline in mean population sizes and the separation of forest remnants by non-forest land can affect the main genetic processes of genetic drift, gene flow, selection and mating.

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,Pashkevich, Michael, Turner, Edgar

Forest fragmentation: another perspective
Trends in Ecology & Evolution, 1998In 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.

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 ...

The Paradox of Forest Fragmentation Genetics
Conservation Biology, 2008Abstract: 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 ...

Cognitive Mapping of Forest Fragments
2021The analysis of spatial cognition (i.e., people's ability to locate sites in the geographic space) can help land planning and forest management by predicting the behavior and reactions of people towards specific landscapes. To achieve this goal, it is of utmost importance to design robust, replicable methods; this is the purpose of this study.

Nature, 1998
Twenty years ago a unique ecological experiment was set up, to monitor the effects of a rapid influx of people into one of the most sparsely populated areas in the world — the Amazon. Scientists have now met in Manau, Brazil, to discuss the results of this experiment.

Forest Fragmentation: Implications for Sustainable Private Forests
Journal of Forestry, 2000Abstract The long-term trend for private forests in the United States is that of more people owning smaller pieces of wooded land for amenity values. This trend shows no sign of slowing, and indications are that it may be speeding up. The fragmenting of forests into smaller pieces appears to be driven by powerful social and demographic ...

This book provides a comparative analysis of the various approaches to environmental federalism and a consideration of what each system might learn from the others. Each chapter focuses on a different regime, and together they offer a broad overview of the field as well as original theory and policy analysis that is sure to meaningfully contribute to ...
