1. Can the native shore crabs (Carcinus maenas) become a barrier to the invasion of the round goby (Neogobius melanostomus) in Öresund, southern Baltic Sea?
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : The round goby (Neogobius melanostomus) is a non-indigenous species to the Baltic Sea that has drawn the attention of many researchers in the last decade due to its rapid spreading and its impact on the local fauna. With recent concerns about the dispersal of the round goby towards the North Sea, the aim of this study was to determine if the native shore crab could compete with the invaders and prevent their advance.

2. Effects of global warming on Eurasian perch (Perca fluviatilis) in the Baltic Sea : does the growth response to increased temperatures differ along a latitudinal gradient?
Master-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : Anthropogenically caused climate change, i.e. global warming, is anticipated to affect all living organisms. Particularly ectotherms are predicted to show strong responses to the increased warming, as their body temperature closely tracks ambient temperatures and because body temperature profoundly affects many physiological functions e.

4. Biodiversity assessment for coastal fish communities in the Baltic Sea
Master-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : Biodiversity becomes of increasing concern in management of marine ecosystems. Measures of biodiversity are numerous and have been largely developed. Biodiversity can be partitioned in different components that indicate, for example, spatial and temporal changes in any communities. LÄS MER
5. Changes in size distribution of lakes in the Nadym catchment, northern Russia
Kandidat-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)Sammanfattning : Because of climate change and resource development there is an ongoing increase in the attention directed towards high latitude areas. Over the last years, warming in the Arctic has accelerated quickly. The warming climate can possibly lead to thawing of ground ice, which in turn leads to alterations of the cryosphere. LÄS MER
