Assessment of endocrine disrupting activities in the aquatic environment
(Åbo Akademi - Åbo Akademi University, 16.01.2009)Hormonstörande ämnen är syntetiska eller naturliga ämnen som stör organismers hormonsystem och bidrar till könsförvirring och sterilitet. Sådana ämnen kommer i ökande takt ut i vattenmiljön genom rester av läkemedel, ... -
Distribution and role of macrophytes in coastal lagoons : implications of critical shifts
(Åbo Akademi - Åbo Akademi University, 26.11.2010)Crossroads, crucibles and refuges are three words that may describe natural coastal lagoon environments. The words refer to the complex mix of marine and terrestrial influences, prolonged dilution due to the semi-enclosed ... -
Patterns and processes of littoral zooplankton composition in relation to the trophic state of the environment
(Åbo Akademi - Åbo Akademi University, 31.08.2012) -
People and the intertidal : human induced changes, biodiversity loss, livelihood implications and management in the Western Indian Ocean
(Åbo Akademi - Åbo Akademi University, 21.09.2012)The intertidal zone in the Western Indian Ocean (WIO) provides several important ecosystem services, but the intertidal is experiencing an accelerating loss of habitats and biodiversity, due to among other factors, an ... -
Climate driven changes in temperature, pH and food quality : effects on copepod reproduction
(Åbo Akademi - Åbo Akademi University, 12.10.2012)Increased emissions of greenhouse gases into the atmosphere are causing an anthropogenic climate change. The resulting global warming challenges the ability of organisms to adapt to the new temperature conditions. However, ... -
Dispersal and metacommunity dynamics in a soft-sediment benthic system : how well is the seafloor connected?
(Åbo Akademi - Åbo Akademi University, 19.12.2012) -
Biodiversity and ecosystem functioning in angiosperm communities in the Baltic Sea
(Åbo Akademi - Åbo Akademi University, 22.02.2013)The biological variation in nature is called biodiversity. Anthropogenic pressures have led to a loss of biodiversity, alarming scientists as to what consequences declining diversity has for ecosystem functioning. The ... -
Disturbance and ecosystem functioning : the role of changes in benthic biological traits
(Åbo Akademi - Åbo Akademi University, 14.06.2013)Rapid changes in biodiversity are occurring globally, as a consequence of anthropogenic disturbance. This has raised concerns, since biodiversity is known to significantly contribute to ecosystem functions and services. ... -
Stop bugging me! : diversity in appearance of warning coloration
(Åbo Akademi - Åbo Akademi University, 18.10.2013)In nature, many animals use body coloration to communicate with each other. For example, colorations can be used as signals between individuals of the same species, but also to recognise individuals of other species, and ... -
Of milquetoasts and daredevils : personalities in female eiders
(Åbo Akademi - Åbo Akademi University, 17.01.2014)Traditionally biologists have often considered individual differences in behaviour or physiology as a nuisance when investigating a population of individuals. These differences have mostly been dismissed as measurement ... -
Interpreting marine benthic ecosystem functioning in coastal waters: validating the biological trait concept
(Åbo Akademi - Åbo Akademi University, 21.03.2014)Coastal areas harbour high biodiversity, but are simultaneously affected by rapid degradations of species and habitats due to human interactions. Such alterations also affect the functioning of the ecosystem, which is ... -
Anti-predator adaptations in aquatic environments
(Åbo Akademi - Åbo Akademi University, 11.04.2014)Predation is an important selective force that has led to the evolution of a variety of fascinating anti-predator adaptations, such as many types of protective coloration and prey behaviours. Because the evolution of ... -
Phase variation in Flavobacterium psychrophilum : influence on host-pathogen interactions
(Åbo Akademi - Åbo Akademi University, 28.05.2014)- -
From genes to communities : stress tolerance in eelgrass (Zostera marina)
(Åbo Akademi - Åbo Akademi University, 31.10.2014)Shallow coastal areas are dynamic habitats that are affected by a variety of abiotic and biotic factors. In addition to the natural environmental stress, estuarine and coastal seagrass ecosystems are exposed to effects of ... -
Macroalgae across environmental gradients : tools for managing rocky coastal areas of the northern Baltic Sea
(Åbo Akademi - Åbo Akademi University, 21.11.2014)Macroalgae are the main primary producers of the temperate rocky shores providing a three-dimensional habitat, food and nursery grounds for many other species. During the past decades, the state of the coastal waters has ... -
From genotype to phenotype : diversity and population structure of Flavobacterium psychrophilum
(Åbo Akademi - Åbo Akademi University, 29.05.2015)Flavobacterium psychrophilum is the etiological agent of bacterial cold-water disease (BCWD) causing high fish mortalities and significant economic losses to the freshwater salmonid aquaculture industry around the world. ... -
Spatial and temporal variation in fish populations and assemblages in coastal waters of the northern Baltic Proper
(Åbo Akademi - Åbo Akademi University, 12.06.2015)The distribution and traits of fish are of interest both ecologically and socio-economically. In this thesis, phenotypic and structural variation in fish populations and assemblages was studied on multiple spatial and ... -
Genetic diversity and phenotypic variability of phytoplankton populations in the Baltic Sea
(Åbo Akademi - Åbo Akademi University, 18.09.2015)- -
Effects of algal turbidity on foraging and antipredator behaviour of the three-spined stickleback (Gasterosteus aculeatus)
(Åbo Akademi - Åbo Akademi University, 23.10.2015)The aim of this thesis was to examine how aquatic organisms, such as fish, behave in an altered environmental condition. Many species of fish use vision as their primary tool to gain information about their surrounding ... -
Dynamic ecosystems under anthropogenic stress : how does macrotidal sandy fauna respond to green tides?
(Åbo Akademi - Åbo Akademi University, 20.05.2016)Highly dynamic systems, often considered as resilient systems, are characterised by abiotic and biotic processes under continuous and strong changes in space and time. Because of this variability, the detection of overlapping ...
