6. Antibiotic Resistance in Enterobacteriaceae Isolated from Wild Birds
Abstract : The presence and spread of clinically important antibiotic-resistant bacteria in reservoirs from natural environments are not well studied compared to the clinical environments. The overall aim of this project was to study the presence of clinically important antibiotic-resistant bacteria in a reservoir from natural environments. READ MORE

8. Population Dynamics and Conservation of the Sand Lizard (Lacerta agilis) on the Edge of its Range
Abstract : The sand lizard (Lacerta agilis) reaches the northern periphery of its distribution in south-central Sweden, where small, isolated relict populations occur in pine heath forests on sandy sediments. Modern forestry and fire suppression have reduced the amount of suitable open habitat for the species in this area and seem to be important for its decline. READ MORE

9. Population size and genetic diversity of Nigerian lions (Panthera leo)
Abstract : High growth rate in human populations, agricultural developments and industrialization have impinged negatively on the natural habitats of most large carnivores, causing fragmentation, isolation and consequently reduction in population size. Lions (Panthera leo) that once roamed most parts of Southern Europe, Asia, the Middle East, North America, northern part of South America and most parts of Africa are today found only in parts of sub-Saharan Africa and at a single site in India.
