Urban Landscapes and Sustainable Cities
Provedor de dados: 7
Autores: Andersson, Erik; Stockholm University; erik.andersson@ecology.su.se.
Ecological research targeting sustainable urban landscapes needs to include findings and methods from many lines of ecological research, such as the link between biodiversity and ecosystem function, the role of humans in ecosystems, landscape connectivity, and resilience. This paper reviews and highlights the importance of these issues for sustainable use of ecosystem services, which is argued to be one aspect of sustainable cities. The paper stresses the need to include social and economic factors when analyzing urban landscapes. Spatially explicit data can be used to assess the roles different green areas have in providing people with ecosystem services, and whether people actually have access to the services. Such data can also be used to assess...

Despite the documented negative effects of roads on wildlife, ecological research on road effects has had comparatively little influence on road planning decisions. We argue that road research would have a larger impact if researchers carefully considered the relevance of the research questions addressed and the inferential strength of the studies undertaken. At a workshop at the German castle of Rauischholzhausen we identified five particularly relevant questions, which we suggest provide the framework for a research agenda for road ecology: (1) Under what circumstances do roads affect population persistence? (2) What is the relative importance of road effects vs. other effects on population persistence? (3) Under what circumstances can road effects be...

Riparian wildlife richness along the Luján River
Provedor de dados: 67
Autores: Guichón,M Laura; Cassini,Marcelo H.
Riparian environments are usually characterized by high biological diversity, however, habitat degradation results from intensive use of the bank and the water course, and exploitation of the surrounding land. The Luján River basin, located in East-central Argentina, shows two distinct geomorphologic portions: the Pampean and the Deltaic portions, which in turn can be subdivided based on physiographic and land use features. Our objective was to compare riparian wildlife richness among the three zones of the Pampean portion (upper, middle, and lower), and between the two zones of the Deltaic portion (protected and antropic). From March to October 1997, 82 transects were randomly placed along the banks of the Luján River. We surveyed the presence of coypus,...

Bird diversity along a gradient of fragmented habitats of the Cerrado
Provedor de dados: 42
Autores: JESUS,SHAYANA DE; PEDRO,WAGNER A.; BISPO,ARTHUR A.
ABSTRACT Understanding the factors that affect biodiversity is of central interest to ecology, and essential to species conservation and ecosystems management. We sampled bird communities in 17 forest fragments in the Cerrado biome, the Central-West region of Brazil. We aimed to know the communities structure pattern and the influence of geographical distance and environmental variables on them, along a gradient of fragmented habitats at both local and landscape scales. Eight structural variables of the fragments served as an environmental distance measurement at the local scale while five metrics served as an environmental distance measurement at the landscape scale. Species presence-absence data were used to calculate the dissimilarity index. Beta...
