Food sources of macrobenthos in an estuarine seagrass habitat (Zostera noltii) ...
Vafeiadou, Anna-Maria; Materatski, Patrick; Adão, Helena; De Troch, Marleen; Moens, TomStable carbon and nitrogen isotope analysis was used to examine the resources and position of macrobenthos in an estuarine seagrass food web in two sampling moments, during summer and winter. The contribution of each food source to the carbon requirements of consumers was estimated by a mixing model. The used carbon sources were largely seagrass associated, although seagrass tissues were utilized by only few sp...
Sample acidification effects on carbon and nitrogen stable isotope ratios of ma...
Vafeiadou, Anna-Maria; Adão, Helena; De Troch, Marleen; Moens, TomAcidification treatment has been used in most stable isotope studies to eliminate inorganic non-dietary carbon, allowing d13C measurement of organic carbon needed for trophic studies. Because only limited information about the acidification effects on isotopic ratios exists in the literature, we provide an assessment of such effects for a wide range of benthic macroinvertebrates from estuarine intertidal sedime...
Food web analysis of meiobenthos in estuarine seagrss bed.
Vafeiadou, Anna-Maria; Materatski, Patrick; Adao, Helena; De Troch, Marleen; Moens, HelenaThis study examines the resource use and trophic position of nematodes and harpacticoid copepods at a genus/species level in an estuarine food web in Zostera noltii beds and in adjacent sediments, using natural abundances of stable carbon and nitrogen isotopes. Microphytobenthos is among the main resources of most taxa, but seagrass-associated resources also contribute to meiobenthos nutrition, with seagrass de...
Recovery of benthic nematode assemblages after a major collapse of Zostera nolt...
Materatski, Patrick; Vafeiadou, Anna-Maria; De Troch, Marleen; Moens, Tom; Adão, HelenaDuring 2008, Zostera noltii seagrass beds of the Mira estuary (SW coast of Portugal) suffered a total collapse, though during 2009 slight symptoms of their recovery were already observed. This association of events, in a short period of time, creates a rare opportunity for obtaining new knowledge concerning natural recovery of ecosystems and habitats. The principal goal is to analyse nematode community response...
