Spatial distributions of phytoplankton in rock pools : metacommunities to molecules
(Åbo Akademi University, 28.04.2017)Ecological studies on how populations and communities assemble and function traditionally focussed on the effects of local environmental conditions and species interactions. Still, no species, the consequences of its actions ... -
Copepods in a changing sea : ocean acidification, long-term changes and short-term variability
(Åbo Akademi University, 19.05.2017)The rapid increase in atmospheric carbon dioxide is causing global warming but also changes in the ocean chemistry. When carbon dioxide dissolves in seawater it changes the carbonate chemistry towards lower levels of ... -
Ocean acidification in the Baltic Sea : implications for the bivalve Macoma balthica
(Åbo Akademi University, 12.04.2017)The Baltic Sea is one of the most human-impacted sea areas in the world and its ecosystems are exposed to a variety of stressors of anthropogenic origin. Large changes in the environmental conditions, species and communities ... -
Phosphorus in the sediments of the northern Baltic Sea archipelagos : internal P loading and Its impact on eutrophication
(Åbo Akademi University, 31.03.2017)In the 20th century Eutrophication as a result of anthropogenic enrichment of nutrients has become a global problem in marine coastal waters. In the Baltic Sea, eutrophication is considered the most severe environmental ... -
Patterns in diversity and function of benthic fauna in a coastal system under environmental change
(Åbo Akademi University, 10.03.2017)Increasing changes in environmental conditions are reshaping marine ecosystems and their communities on a global scale. Coastal areas are particularly vulnerable as environmental stressors have a stronger impact due to the ... -
Dynamic ecosystems under anthropogenic stress : how does macrotidal sandy fauna respond to green tides?
(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 ... -
Effects of algal turbidity on foraging and antipredator behaviour of the three-spined stickleback (Gasterosteus aculeatus)
(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 ... -
Genetic diversity and phenotypic variability of phytoplankton populations in the Baltic Sea
(Åbo Akademi University, 18.09.2015)- -
Spatial and temporal variation in fish populations and assemblages in coastal waters of the northern Baltic Proper
(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 ... -
Macroalgae across environmental gradients : tools for managing rocky coastal areas of the northern Baltic Sea
(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 genes to communities : stress tolerance in eelgrass (Zostera marina)
(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 ... -
Phase variation in Flavobacterium psychrophilum : influence on host-pathogen interactions
(Åbo Akademi University, 28.05.2014)- -
Anti-predator adaptations in aquatic environments
(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 ... -
Interpreting marine benthic ecosystem functioning in coastal waters: validating the biological trait concept
(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 ... -
Of milquetoasts and daredevils : personalities in female eiders
(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 ... -
Stop bugging me! : diversity in appearance of warning coloration
(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 ... -
Disturbance and ecosystem functioning : the role of changes in benthic biological traits
(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. ... -
Biodiversity and ecosystem functioning in angiosperm communities in the Baltic Sea
(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 ... -
Dispersal and metacommunity dynamics in a soft-sediment benthic system : how well is the seafloor connected?
(Åbo Akademi University, 19.12.2012) -
Climate driven changes in temperature, pH and food quality : effects on copepod reproduction
(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, ...
