Marine Food Webs : an Exploration of Past Structure and Function to Prepare for the Future
(Åbo Akademi - Åbo Akademi University, 27.04.2022)Food webs depict species and their trophic interactions arranged in a network. Changes in food web structure ultimately beget changes in functioning. In recent years, environmental and anthropogenic pressures have reshaped ... -
Facilitation and Feedbacks in Seagrass Communities : Testing the Role and Context-Dependency of Ecosystem Engineers
(Åbo Akademi - Åbo Akademi University, 18.12.2020)In physically unstable habitats such as coastal soft sediments, facilitative interactions are essential for structuring associated ecological communities. Here, habitat amelioration by ecosystem engineers such as seagrasses, ... -
Coastal Habitats and their Importance for the Biodiversity of Faunal Communities
(Åbo Akademi - Åbo Akademi University, 24.06.2020)Coastal habitats represent highly productive areas serving important functions for multiple organism groups. These shallow areas generally maintain high faunal biodiversity, providing important ecosystem goods and services, ... -
Drivers of plankton populations in the Baltic Sea
(Åbo Akademi University, 20.05.2020)Plankton are at the base of the food chain, and identifying their drivers is important for understanding how climate change will impact populations and communities. The main aim of my thesis was to quantify the effects of ... -
Flavobacterium psychrophilum adhesion and biofilm formation
(Åbo Akademi - Åbo Akademi University, 18.05.2018)Flavobacterium psychrophilum causes serious infections in farmed rainbow trout (Oncorhynchus mykiss) and subsequent substantial economic losses to fish farmers, globally. Over the past years, few studies have conclusively ... -
Spatial distributions of phytoplankton in rock pools : metacommunities to molecules
(Åbo Akademi - 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 - 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 - 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 - 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 - 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 - 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 - 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 - 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 - 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 ... -
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. ... -
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 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 ... -
Phase variation in Flavobacterium psychrophilum : influence on host-pathogen interactions
(Åbo Akademi - Åbo Akademi University, 28.05.2014)- -
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 ... -
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 ...
