Spatial distributions of phytoplankton in rock pools : metacommunities to molecules
(Åbo Akademi - Åbo Akademi University, 2017-04-28)
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 ...
People and the intertidal : human induced changes, biodiversity loss, livelihood implications and management in the Western Indian Ocean
(Åbo Akademi - Åbo Akademi University, 2012-09-21)
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 ...
Of milquetoasts and daredevils : personalities in female eiders
(Åbo Akademi - Åbo Akademi University, 2014-01-17)
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 ...
Spatial and temporal variation in fish populations and assemblages in coastal waters of the northern Baltic Proper
(Åbo Akademi - Åbo Akademi University, 2015-06-12)
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 ...
Disturbance and ecosystem functioning : the role of changes in benthic biological traits
(Åbo Akademi - Åbo Akademi University, 2013-06-14)
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. ...
Interpreting marine benthic ecosystem functioning in coastal waters: validating the biological trait concept
(Åbo Akademi - Åbo Akademi University, 2014-03-21)
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 ...
Climate driven changes in temperature, pH and food quality : effects on copepod reproduction
(Åbo Akademi - Åbo Akademi University, 2012-10-12)
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, ...
Anti-predator adaptations in aquatic environments
(Åbo Akademi - Åbo Akademi University, 2014-04-11)
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 ...
Effects of algal turbidity on foraging and antipredator behaviour of the three-spined stickleback (Gasterosteus aculeatus)
(Åbo Akademi - Åbo Akademi University, 2015-10-23)
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 ...
Stop bugging me! : diversity in appearance of warning coloration
(Åbo Akademi - Åbo Akademi University, 2013-10-18)
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 ...
