Última The Effects of Urban Sprawl on Birds at Multiple Levels of Biological Organization Ecology and Society Blair, Robert; University of Minnesota; blairrb@umn.edu. Urban sprawl affects the environment in myriad ways and at multiple levels of biological organization. In this paper I explore the effects of sprawl on native bird communities by comparing the occurrence of birds along gradients of urban land use in southwestern Ohio and northern California and by examining patterns at the individual, species, community, landscape, and continental levels. I do this by assessing the distribution and abundance of all bird species occupying sites of differing land-use intensity in Ohio and California. Additionally, I conducted predation experiments using artificial nests, tracked the nest fate of American Robins and Northern Cardinals, and assessed land cover in these sites. At the individual level, predation on artificial...

Ano: 2004 Influence of landscape structure on Euglossini composition in open vegetation environments Biota Neotropica Moreira,Eduardo Freitas; Santos,Rafaela Lorena da Silva; Silveira,Maxwell Souza; Boscolo,Danilo; Neves,Edinaldo Luz das; Viana,Blandina Felipe. Abstract The fauna of Euglossini bees is poorly known in savanna regions, making it difficult to understand how these bees use open vegetation environments. The aim of this study was to evaluate the influence of landscape structure on species abundance and composition of Euglossini bees in naturally heterogeneous savanna landscapes. Nine sites were sampled monthly using six traps with chemical baits. Three aromatic essences (eucalyptol, methyl salicylate and vanillin) were used to attract the Euglossini. Surrounding environmental conditions were measured using three independent variables, calculated in multiple scales: index of local vegetation and two landscape indices (Shannon Diversity and area-weighted shape). We compared the competing hypotheses... Tipo: Info:eu-repo/semantics/article Palavras-chave: Bees; Habitat amount hypothesis; Landscape heterogeneity; Landscape configuration.
