The spatial behaviour of 10 Southern river otters Lontra provocax was analysed using radio-tracking data collected in the Queule River, Southern Chile. The estimated otter density was 0.25 individuals km(-1). Females with cubs and adult otters d[...]

Human land use has modified the structure and function of terrestrial landscapes throughout much of the world, with cropping and livestock grazing the major drivers of landscape change. In many tropical, sub-tropical, temperate and Mediterranean[...]

Understanding of how a large landscape or network of conservation areas and habitats of red-listed species change in time is an important topic when addressing the temporal interplay between protected areas and matrix. We developed models of hab[...]

Empirical habitat selection models aid managers by predicting distribution patterns, but recent critiques urge a fuller, application of available methods. We used a suite of habitat modelling techniques to identify factors influencing the distri[...]

Functional connectivity is a measure of the interaction of landscape structure and a species'dispersal ability to determine the degree to which a landscape facilitates movement among patches. Dispersal through an inhospitable matrix requires tha[...]

An effective nature reserve network design should reflect the ecological requirements of target species, while simultaneously considering costs. In this study, we propose a design method that considers the ecological role of the spatial arrangem[...]

Techniques such as rewetting, topsoil removal, diaspore transfer or combinations of these are increasingly applied in fen meadow and flood meadow restoration in Western Europe. In this paper, we present a quantitative assessment of the effective[...]

Projection of species-response to climate change scenarios is a key tool in conservation strategy. Previous studies have projected climate change impacts for animal and vascular plant species using the 'bioclimatic envelope' approach. In this st[...]

We analyze the impact of grazing on dung beetle diversity at the Barranca de Metztitlan Biosphere Reserve, a xeric ecosystem in central Mexico with a long history of use by humans. We compared the community structure, as well as the alpha and be[...]

Impacts of plant invasions are largely scale-dependent and responses to the same exotic species may vary among communities. Since impacts caused by individual trees could anticipate consequences of a closed canopy of an invader, we studied the r[...]

Fragmentation of terrestrial landscapes has exacerbated the need to understand the spatial requirements of organisms, especially those that undergo seasonal migrations, such as pond-breeding amphibians. Pond-breeding amphibians spend much of the[...]

In South-East Asia patterns of forest loss can predict the number of threatened birds. on the oceanic islands of Wallacea, small-scale agriculture, rather than commercial logging, is the main cause of forest loss and conversion, but few studies [...]

In many parts of the world, there is increasing interest among scientists, managers, and communities in merging long-enduring customary practices such as taboos that limit resource use with contemporary resource management initiatives. Here, we [...]

In Europe, many semi-open pasture woodlands with oaks (Quercus robur and Q. petraea) have been invaded by other trees. The management alternatives for such stands are often debated. Protection (i.e. no cutting) versus partial harvest to favour o[...]
