Benthic Nematode assemblages response to seagrass beds spatial heterogeneity in...
Materatski, Patrick; Moens, Tom; Vafeiadou, Anna-Maria; Adão, HelenaAfter a seagrass beds (Zostera noltii) colapse in 2008 of the Mira estuary (SW coast of Portugal) symptoms of early recovery were observed. The principal goal of this study is to assess the evolution and resilience of the benthic nematodes assemblages during the natural recovery of the seagrass beds through analysis of the spatial and temporal differences in structural and functional characteristics of the com...
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...
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...
Benthic Nematodes Assemblages as Indicators of Spatial Heterogeneity in Early N...
Adão, Helena; Materatski, Patrick; Vafeiadou, Anna-Maria; Moens, TomDuring 2008, Zostera noltii seagrass beds of the Mira estuary (SW coast of Portugal) suffered a total collapse. During 2009 symptoms of early recovery were observed. The availability of pre-collapse data and the sequence of sudden collapse followed by early and gradual recovery create a rare natural experiment on recovery and resilience of seagrass ecosystems. The principal goal of this study is to assess the ...

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...
