This paper contempts optical and radar data complementarity for the characterization and cartography of urban landscapes. Our study site, the city of Caiena, is located in French Guiana (4,56º Latitude North). Complex urban dynamics result in a significant diversity of unstable urban habitats, for which optical remote sensing does bring solutions in terms of mapping and monitoring. But because ...

Strategies for conserving plant diversity in agroecosystems generally focus on either expanding land area in non-crop habitat or enhancing diversity within crop fields through changes in within-field management practices. In this study, we compare effects on landscape-scale species richness from such land-sharing or land-sparing strategies. We collected data in arable field, grassland, pasture,...

Streams, as low-lying points in the landscape, are strongly influenced by the stormwaters, pollutants, and warming that characterize catchment urbanization. River restoration projects are an increasingly popular method for mitigating urban insults. Despite the growing frequency and high expense of urban stream restoration projects, very few projects have been evaluated to determine whether they...

We examined temporal changes in macrofaunal α- and β-diversity over several spatial scales (within patches, among patches, across landscapes and across regions) in Long Island Sound on the northeast USA coast. Regional ε-diversity was estimated at 144 taxa, however γ-diversity fluctuated over time as did α- and β-diversity components. Based on additive partitioning, patch- and region-scale β-di...

Urban futures that are more resilient and sustainable require an integrated social-ecological system approach to urban policymaking, planning, management, and governance. In this article, we introduce the Urban Biodiversity and Ecosystem Services (URBES) and the Cities and Biodiversity Outlook (CBO) Projects as new social-ecological contributions to research and practice on emerging urban resil...

Landscape is an important object for research on local culture from a cultural geographical perspective. It is the spatial nature of memory that has seen the integrative study of memory and landscape receive increased attention from human geographers. The Qiqiao Festival is a traditional folk festival in the Lingnan region of Southern China. After half a century of suppression, the Qiqiao Festi...
