Effects of exurban development on biodiversity: patterns, mechanisms, and research needs
Andrew J. Hansen,Richard L. Knight,John M. Marzluff,Scott Powell,Kathryn Brown,Patricia H. Gude,Kingsford Jones +6 more
TL;DR: In this article, the authors examined the patterns of biodiversity response and the ecological mechanisms that may underlie these responses and found that many native species have reduced survival and reproduction near homes, and native species richness often drops with increased exurban densities.
Journal ArticleDOI
Increasing isolation of protected areas in tropical forests over the past twenty years
TL;DR: In this paper, the authors used multiple sources of satellite data to estimate the extent of forest habitat and loss over the last 20 years within and surrounding 198 of the most highly protected areas (IUCN status 1 and 2) located throughout the world's tropical forests.
Journal ArticleDOI
Ecological mechanisms linking protected areas to surrounding lands
Andrew J. Hansen,Ruth DeFries +1 more
TL;DR: This paper presents a conceptual model of protected areas embedded within larger ecosystems that often include surrounding human land use, and explores a comprehensive set of ecological mechanisms by which land use on surrounding lands may influence ecological processes and biodiversity within reserves.
Journal ArticleDOI
Global change in forests: responses of species, communities, and biomes
Andrew J. Hansen,Ronald P. Neilson,Virginia H. Dale,Curtis H. Flather,Louis R. Iverson,David J. Currie,Sarah L. Shafer,Rosamonde R. Cook,Patrick J. Bartlein +8 more
TL;DR: In this article, the authors synthesize current knowledge of interactions among climate, land use, and biodiversity, and summarize the results of new analyses on the potential effects of human-induced climate change on forest biodiversity.
Book
Landscape boundaries : consequences for biotic diversity and ecological flows
TL;DR: In this paper, the effect of ecotone patterning on community diversity and landscape functioning is examined, and the role of the ecotones in controlling energy, material and organisms between ecosystems is explored.
