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 ... -
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 ... -
Breeding during a Predation Regime Shift : Behavioural and physiological responses of female common eiders facing the recovery of their native predator
(Åbo Akademi University & CNRS–La Rochelle Université, 14.12.2023)Predation is a key selective force driving prey trait evolution. Yet, the extent to which predator-consumptive and predation risk effects shape phenotypes is still poorly understood. Since predation risk increases the cost ... -
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, ... -
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, ... -
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 ... -
Dispersal and metacommunity dynamics in a soft-sediment benthic system : how well is the seafloor connected?
(Åbo Akademi - Åbo Akademi University, 19.12.2012) -
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 ... -
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. ... -
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 ... -
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 ... -
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, ... -
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 ... -
Genetic diversity and phenotypic variability of phytoplankton populations in the Baltic Sea
(Åbo Akademi - Åbo Akademi University, 18.09.2015)- -
Human Ecosystem Engineering : Effects and Feedback in Coastal Benthic Systems
(Åbo Akademi - Åbo Akademi University, 16.02.2024)In the attempt to enhance their environment, humans are causing changes in ecosystems worldwide, by acting as ecosystem engineers. Changes in ecosystems, caused by any ecosystem engineering species, have the potential to ... -
Implications of the Integration of a Non-Native Fish into Coastal Communities
(Åbo Akademi - Åbo Akademi University, 14.03.2024)The Baltic Sea ecosystem is undergoing unprecedented changes in abiotic conditions due to the combined effects of climate change, eutrophication, and bottom-water deoxygenation. Non-native species, introduced outside their ... -
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 ... -
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 ... -
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 ... -
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 ...
