1. 1. Predicting bat occurrence : evaluation of a connectivity-based habitat index for Swedish bats

   University essay from SLU/Dept. of Ecology

   Author : Gesa von Hirschheydt; [2018]
   Keywords : bats Chiroptera ; bat habitat index; ecological impact assessment; flight friction; cost distance analysis; landscape permeability;

   Abstract : Ecological impact assessments are required for all large infrastructure or exploitation projects because of their effects on environment and species. Methods that would make such assessments more standardised, efficient and reliable are highly desirable in today’s society, where many species are decreasing due to human-induced habitat modifications.

3. 2. EU tree density limits in wooded pastures and their effects on bat populations within traditional agricultural landscapes

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Heather Wood; [2016]
   Keywords : ;

   Abstract : The European Union’s Common Agricultural Policy (CAP) recommends subsidies are only granted for wooded pastures with less than 100 trees per hectare. This arbitrary guidance exists despite these habitats being among the most biodiverse in rural Europe. READ MORE

4. 3. Influence of landscape scale and habitat distribution on individual bat species and bat species richness

   University essay from Linköpings universitet/Biologi; Linköpings universitet/Tekniska högskolan

   Author : Martin Brüsin; [2013]
   Keywords : Bat species; Species richness; habitat; habitat fragmentation; scale dependent;

   Abstract : Habitat fragmentation is one of the most important factors affecting species extinction and biodiversity loss, Species habitat response expects to differ with habitat feature at different spatial scales and this study was to identify how bat diversity and individual bat species respond to different habitat amounts. The local bat species richness was observed in 156 different locations in Östergötland and the proportion of different habitats were calculated for circular areas with diameters ranging from 400 m.

5. 4. Bat species richness and activity in forest habitats close to lakes versus far from lakes,  in Sweden

   University essay from Institutionen för biologi och miljö (BOM)

   Author : Silvia Zuniga; [2013]
   Keywords : bats; bat species richness; bat activity; lakes; wind farming; Sweden;

   Abstract : The long-term effects of large-scale changes in forestry, agriculture and other land use on habitats and the large-scale expansion of wind farming  affects bats foraging environments. In order to predict consequences of exploitations on local bat species and populations, good surveys are important. READ MORE

6. 5. Seasonal variations in distribution patterns and movements of bats in relation to habitat characteristics

   University essay from SLU/Swedish Biodiversity Centre

   Author : Artiom Bondarenco; [2009]
   Keywords : key habitats; bats; Moldova; critical seasons; distribution; movements;

   Abstract : Different types of land use, such as forestry and agriculture, change the distribution and composition of habitats in the landscape. In order to understand the consequences of that for different organisms, and to find methods for combining conservation with production of crops, timber and other products it is important to collect information on distribution pattern, habitat selection and movements of different organisms.
