1. 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.

2. Plant community assembly during succession from arable fields to semi-natural grassland
Abstract : Large areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. READ MORE

3. Dispersal of ticks and their microorganisms by African-Western Palaearctic migratory birds
Abstract : In Europe, tick-borne diseases are the most widespread and common vector-borne diseases and their geographical distribution is increasing. The dispersal of ticks depends on the movements of their vertebrate hosts. Avian hosts are more likely to be involved in long-distance range expansion of ticks due to their migration pattern.

4. HOST EPIGENETIC REGULATOR BMI1 AND VIRAL FIBER PROTEIN FOR EQUILIBRIUM BETWEEN ADENOVIRUS AND HOST
Abstract : Human adenoviruses (Ads) are broadly used in cancer gene therapy, vaccine development and gene delivery. The modified Ad5 or Ad2 viruses have been successfully used as oncolytic agents in pre-clinical studies. However they could not be translated into clinic utility due to a number of limitations including inefficient Ad spread among tumor cells. READ MORE

5. Bark beetles facilitate the establishment of wood decay fungi
Abstract : Forests in the northern hemisphere are largely dominated by conifers and provide a key habitat for a multitude of species. Wood decay fungi, i.e. basidiomycetes, are important for nutrient cycling. READ MORE
