Landscape-scale Edge Effect in Predation Risk in Forest-farmland Mosaics of Central Europe
Springer Science and Business Media LLC - Tập 20 - Trang 927-940 - 2005
Avian nest predation is known to increase with the degree of forest fragmentation. A common explanation is that farmland allows for high densities of generalist predators, and predators penetrating into the forest cause higher nest losses at forest-farmland edges than in forest interiors. In contrast to numerous patch-level studies of forest edge effects conducted earlier, we broadened the spatial......
Research article Canopy dynamics and human caused disturbance on a semi-arid landscape in the Rocky Mountains, USA
Springer Science and Business Media LLC - Tập 20 - Trang 1-17 - 2005
Invasion of grasslands by woody plants has been identified as a key indicator of changes in ecosystem structure and function in arid and semi-arid rangelands throughout the world. We investigated changes in the balance between woody and herbaceous components of a semi-arid landscape in western Colorado (USA) using historical aerial photography. Aerial photographs from 1937, 1965–67, and 1994 were ......
Does habitat fragmentation affect landscape-level temperatures? A global analysis
Springer Science and Business Media LLC - Tập 35 - Trang 1743-1756 - 2020
Habitat fragmentation per se (habitat subdivision independent of habitat loss) is a major driver of biodiversity change, potentially due to its impacts on climate. Habitat fragmentation may make landscapes hotter by increasing the amount of habitat edges, but can reduce landscape-level temperatures due to the “vegetation breeze” phenomenon. The plausibility of these two alternative hypotheses is u......
Incorporating habitat suitability, landscape distance, and resistant kernels to estimate conservation units for an imperiled terrestrial snake
Springer Science and Business Media LLC - Tập 37 - Trang 2519-2533 - 2022
Wildlife distributions are often subdivided into discrete conservation units to aid in implementing management and conservation objectives. Habitat suitability models, resistance surfaces, and resistant kernels provide tools for delineating spatially explicit conservation units but guidelines for parameterizing resistant kernels are generally lacking. We used the federally threatened eastern indig......
Multi-scale use of lands providing anthropogenic resources by American Crows in an urbanizing landscape
Springer Science and Business Media LLC - Tập 24 - Trang 281-293 - 2008
The conversion of forests and farmlands to human settlements has negative impacts on many native species, but also provides resources that some species are able to exploit. American Crows (Corvus brachyrhynchos), one such exploiter, create concern due to their impact as nest predators, disease hosts, and cultural harbingers of evil. We used various measures of crow abundance and resource use to de......
Impact of data integration technique on historical land-use/land-cover change: Comparing historical maps with remote sensing data in the Belgian Ardennes
Springer Science and Business Media LLC - Tập 17 - Trang 117-132 - 2002
Historical reconstructions of land-use/cover change often require comparing maps derived from different sources. The objective of this study was to measure land-use/cover changes over the last 225 years at the scale of a Belgian landscape, Lierneux in Ardennes, on the basis of a heterogeneous time series of land cover data. The comparability between the land-cover maps was increased following a me......
Effects of forest patch size on avian diversity
Springer Science and Business Media LLC - Tập 10 - Trang 85-99 - 1995
The effects of landscape patchiness on the diversity of birds of the Georgia Piedmont were investigated during 1993. Birds were sampled along line transects within relatively large (10–13.25 ha) and small (less than 3.25 ha) forest patches located within nonforest agricultural landscapes. Patterns of habitat use in these patches were compared to those in contiguous forest patches larger than 13.25......
The land use–climate change–energy nexus
Springer Science and Business Media LLC - Tập 26 - Trang 755-773 - 2011
Landscape ecology focuses on the spatial patterns and processes of ecological and human interactions. These patterns and processes are being altered by both changing resource-management practices of humans and changing climate conditions associated, in part, with increases in atmospheric concentrations of greenhouse gases. Dominant resource-extraction and land-management activities involve energy,......
Loss and fragmentation of mature woodland reduce the habitat niche breadth of forest birds
Springer Science and Business Media LLC - Tập 33 Số 11 - Trang 1865-1879 - 2018
A comparison of popular approaches to optimize landscape resistance surfaces
Springer Science and Business Media LLC - Tập 34 - Trang 2197-2208 - 2019
Landscape resistance surfaces are often used to address questions related to movement, dispersal, or population connectivity. However, modeling landscape resistance is complicated by the selection of the most appropriate analytical approach and the assignment of resistance values to landscape features. We compare three common approaches used in landscape genetics to assign resistance values to lan......
