1. Population genetic analyses in the orchid genus Gymnadenia : a conservation genetic perspective
Abstract : Small populations are facing a particular risk of extinction due to a lack of appropriate genetic diversity and associated negative effects, factors dealt with in the discipline of conservation genetics. Many orchid species exhibit characteristics that make them a perfect study object in the scope of conservation genetics. READ MORE

2. Seed mobility and connectivity in changing rural landscapes
Abstract : The success or failure of many organisms to respond to the challenges of habitat destruction and a warming climate lies in the ability of plant species to disperse between isolated habitats or to migrate to new ranges. European semi-natural grasslands represent one of the world's most species-rich habitats at small scales, but agricultural intensification during the 20th century has meant that many plant species are left only on small fragments of former habitat.

3. The human pancreatic polypeptide receptor Y4 : Genetic and functional variation
Abstract : Humans are evolutionarily adapted to an environment where food is scarce, but today many live in a world of food abundance. Paired with low physical activity, this may lead to weight gain and obesity. Efficient anti-obesity treatments require understanding of the mechanisms that control hunger, satiety, energy metabolism and body weight. READ MORE

4. Network Based Tools and Indicators for Landscape Ecological Assessments, Planning, and Design
Abstract : Land use change constitutes a primary driving force in shaping social-ecological systems world wide, and its effects reach far beyond the directly impacted areas. Graph based landscape ecological tools have become established as a promising way to efficiently explore and analyze the complex, spatial systems dynamics of ecological networks in physical landscapes.
