Seaweed Invasions and Novel Chemical Defences
(2012-11-08)
Biological invasions pose a risk to the biodiversity and the functioning of ecosystems in invaded areas. The reasons why some introduced species become dominant and widespread in their new environments is still largely an ...
Evolution of the brown algae Fucus radicans and F. vesiculosus in the Baltic Sea
(2013-04-25)
The aim of my thesis was to investigate neutral and adaptive evolution of a lineage of macroalga (Fucus vesiculosus) that entered the Baltic Sea about 6000 years ago, and later gave rise to a new endemic species, F. radicans. ...
Mate choice and its evolutionary consequences in intertidal snails (Littorina spp.)
(2013-05-06)
The ability to recognise potential mates and choose the best possible partner for reproduction is of fundamental importance for most animal species. This thesis presents studies of mate choice in marine snails of the genus ...
Structural and functional studies of the ATP-dependent Clp proteases in cyanobacteria
(2014-09-17)
Proteins are essential in all living organisms and they are involved in a myriad of biological functions. It is vital for cells to have efficient surveillance and quality control systems that ensure damaged proteins are ...
Carbon and nutrient cycling in Afromontane tropical forests at different successional stages
(2016-11-18)
To date, studies of the carbon and nutrient cycling in tropical montane forests have been restricted to a few, mostly neotropical, sites. This thesis investigated the carbon and nutrient cycling of early (ES) and late (LS) ...
Colour signalling in widowbirds and bishops
(2015-08-28)
Sexual selection, i.e. differential mating success due to contest competition or mate choice, has produced an amazing diversity of elaborate sexual signals across the animal kingdom, not least the dazzling colours of birds. ...
Patterns of evolution in a young species, the Baltic seaweed Fucus radicans
(2015-04-29)
To be able to interpret patterns of biodiversity it is important to understand the processes by
which new species evolve and how closely related species remain reproductively isolated and ecologically differentiated. This ...
Ecophysiology of Polar Sea Ice Microorganisms in a Changing World
(2015-10-05)
Earth’s oceans are predominantly cold, with nearly 90% of their volume having temperatures below 5 °C. Microorganisms commonly referred to as psychrophiles have adapted to the temperatures of these cold waters. The most ...
Assessment of dietary patterns and prey consumption of marine mammals: Grey seals (Halichoerus grypus) in the Baltic Sea
(2012-02-09)
The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. In the ...
Chemical mixtures and interactions with detoxification mechanisms and biomarker responses in fish
(2015-01-09)
Several classes of anthropogenic chemicals are present as mixtures in the aquatic environment. However, information of how wildlife species, including fish, are affected by exposures to chemical mixtures is limited. Chemicals ...
