Dynamic ecosystems under anthropogenic stress : how does macrotidal sandy fauna respond to green tides?
(Åbo Akademi - Åbo Akademi University, 2016-05-20)
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 ...
Patterns in diversity and function of benthic fauna in a coastal system under environmental change
(Åbo Akademi - Åbo Akademi University, 2017-03-10)
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 ...
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 ...
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 ...
Macroalgae across environmental gradients : tools for managing rocky coastal areas of the northern Baltic Sea
(Åbo Akademi - Åbo Akademi University, 2014-11-21)
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 ...
