Biodiversity and ecosystem functioning in angiosperm communities in the Baltic Sea
(Åbo Akademi - Åbo Akademi University, 2013-02-22)
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 ...
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. ...
Marine Food Webs : an Exploration of Past Structure and Function to Prepare for the Future
(Åbo Akademi - Åbo Akademi University, 2022-04-27)
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, 2020-12-18)
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, 2020-06-24)
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, 2020-05-20)
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 ...
Human Ecosystem Engineering : Effects and Feedback in Coastal Benthic Systems
(Åbo Akademi - Åbo Akademi University, 2024-02-16)
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 ...
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, 2023-12-14)
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 ...
Implications of the Integration of a Non-Native Fish into Coastal Communities
(Åbo Akademi - Åbo Akademi University, 2024-03-14)
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 ...
