Microhabitat preferences of Biomphalaria pfeifferi and Lymnaea natalensis in a natural and a man-made habitat in southeastern Tanzania. [PDF]

, 2000
Schistosoma mansoni is an important human parasitic disease which is widespread throughout Africa. As Biomphalaria pfeifferi snails act as intermediate host, knowledge of their population ecology is an essential prerequisite towards understanding disease

Transcending scale dependence in identifying habitat with resource selection functions

, 2012
Multi-scale resource selection modeling is used to identify factors that limit species distributions across scales of space and time. This multi-scale nature of habitat suitability complicates the translation of inferences to single, spatial depictions ...

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Reindeer use of alpine summer habitats [PDF]

, 2006
Alpine areas in the Scandinavian mountain region are used for grazing by semi-domesticated reindeer (Rangifer tarandus tarandus) during the snow-free season. These areas are also used for outdoor recreation and tourism.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Targeting Incentives to Reduce Habitat Fragmentation [PDF]

This paper develops a theoretical model to analyze the spatial targeting of incentives for the restoration of forested landscapes when wildlife habitat can be enhanced by reducing fragmentation.

Spatio‐temporal habitat selection shifts in brown trout populations under contrasting natural flow regimes

, 2013
This study was funded by the Spanish Ministry of Science and Innovation through the research project CGL2008-04257/BOS. I. Parra was funded by a postgraduate contract from the Government of Madrid and the European Social Fund (ESF).Understanding the ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Effects of tourism on seasonal movements and fine-scale habitat selection of African lions and spotted hyenas in Etosha National Park, Namibia

Global Ecology and Conservation
Understanding the drivers of habitat selection for apex predators, such as African lions (Panthera leo) and spotted hyenas (Crocuta crocuta), is a vital component of conservation efforts.

Individual heterogeneity in resource selection has implications for mortality risk in white‐tailed deer

Ecosphere, 2020
Individual animals vary in their selection of habitat as a function of sex, age, and experience. Such individual heterogeneity is important when decomposing segments of the population that may or may not respond to habitat or population management, or ...
