Trophic interactions between indigenous and non-indigenous species in Lampedusa Island, Mediterranean Sea Universiteit Gent
Trophic ecology of intertidal harpacticoid copepods, with emphasis on their interactions with bacteria Universiteit Gent
In the era of rapidly changing natural environments, there is an urgent need for understanding biodiversity-ecosystem functioning. Trophic interactions play a key role in structuring the ecosystem. In marine systems, the feeding ecology of the larger-sized species i.e. (top) predators of food webs, is fairly well documented, yet at the basal level of food webs, the complexity of grazer interactions is much higher and trophic linkages are ...
Drought altered trophic dynamics of an important natural saline lake: A stable isotope approach KU Leuven
Climate change and associated droughts threaten the ecology and resilience of natural saline lakes globally. There is a distinct lack of research regarding their ecological response to climatic events in the Global South. This region is predicted to experience climatic events such as El Niño-Southern Oscillation (ENSO) more often and with greater severity with the potential to alter the structure and functioning of aquatic ecosystems ...
Trophic and non-trophic interactions between macrophytes and macroinvertebrates in lowland streams Universiteit Antwerpen
Through their form and functioning, aquatic macrophytes can have a great impact on the macroinvertebrate community in temperate lowland streams. Effects of macrophytes range from abiotic, such as the impact of growth form on water flow, to biotic, such as a macroinvertebrate food source. Although certain interactions between macrophytes and macroinvertebrate have been studied before, much is still unknown about the role of macrophytes within the ...
Dispersal-mediated trophic interactions can generate apparent patterns of dispersal limitation in aquatic metacommunities KU Leuven Universiteit Gent
Ecology Letters (2012) ABSTRACT: Dispersal is a major organising force in metacommunities, which may facilitate compositional responses of local communities to environmental change and affect ecosystem function. Organism groups differ widely in their dispersal abilities and their communities are therefore expected to have different adaptive abilities. In mesocosms, we studied the simultaneous compositional response of three plankton communities ...
Trophic structure of an African savanna river and organic matter inputs by large terrestrial herbivores: A stable isotope approach KU Leuven
© 2018 John Wiley & Sons Ltd Knowledge of trophic structure is important to understand sources and pathways of energy resources in community ecology and to identify determinants of ecosystem changes. Yet, little is known from rivers of African savanna receiving large inputs of terrestrial organic matter and nutrients by large mammalian herbivores. We used Stable Isotope (δ13C and δ15N) Bayesian Ellipses in R (SIBER) and Layman's ...
Determination of fish trophic levels in an estuarine system Universiteit Antwerpen
The concept of trophic level is particularly relevant in order to improve knowledge of the structure and the functioning of an ecosystem. A precise estimation of fish trophic levels based on nitrogen isotopic signatures in environments as complex and fluctuant as estuaries requires a good description of the pelagic and benthic trophic chains and a knowledge of organic matter sources at the bottom. In this study these points are considered in the ...
Influence of salt farming on the habitat, trophic ecology and genetic population structure of macroinvertebrates in mangroves Vrije Universiteit Brussel
The increase in population pressure coupled with ignorance and poverty has promoted human activities responsible for the loss, degradation and fragmentation of mangrove ecosystems along the Western Indian Ocean coast. Solar salt farming is one of the human activities that threaten the mangrove ecosystem. The impacts of solar salt farming on the mangrove ecosystem have received little attention but in some countries its impacts they are on a par ...
Higher trophic levels in the southern North Sea “TROPHOS” Instituut voor Natuur- en Bosonderzoek
TROPHOS is a co-operation between five Belgian institutes (RUG-Marine Biology, KULeuven-Aquatic Ecology, Institute of Nature Conservation, MUMM and VLIZ) and one Dutch institute (NIOO-CEMO) and aims at a better understanding of processes structuring the higher trophic levels in the North Sea. As we will not ignore the link between ecosystem functioning and aquatic biodiversity, our results will also serve in aspects of sustainable management for ...
