“…Long-term changes in the nematode communities from the Kwintebank were attributed to long-term changes in the sedimentological environment in combination with the extra dynamics imposed by the creation and filling up of dredge furrows (Vanaverbeke et al, 2007). Our results show that on a relatively short time scale, the absence of the creation and filling of dredge furrows can lead to the establishment of a more stable nematode community.…”

“…This again suggests that seasonal changes and changes due to unmeasured factors had a minor impact on the observed differences between the central area and the northern area after cessation of the extraction activities. In the northern area, the temporal evolution of stations Kw1 and Kw2 is different as well, which reflects the local impact of sand extraction activities on the nematode communities (Vanaverbeke et al, 2007).…”

“…Analyses in this paper are based on historical data from sampling campaigns conducted in June-September 1978 (Vincx, 1986), February 1997 (Vanaverbeke et al, 2002), December 2001 (Vanaverbeke et al, 2007), and new sampling campaigns in the central and northern area of the Kwintebank in October 2003 and February 2004. The central area was closed for extraction activities in February 2003, while extraction activies continued in the northern part.…”

“…Since federal legislation prohibits further exploitation when a deepening of >5 m with respect to the most recent hydrographical charts occurs, this area had to be closed for extraction activities in February 2003. Nematode community composition at the sandbank changed considerably since the start of the extraction activities, which was attributed to long-term changes in sediment characteristics in combination with additional short-term disturbances by the creation and the filling of dredge furrows (Vanaverbeke et al, 2007). Since nematode communities are generally accepted to be a good monitoring tool for assessing changes in the benthic environment (Kennedy and Jacoby, 1999), we sampled these communities to assess a possible restoration of the community characteristics after cessation of the activities by comparing the post-extraction data with (1) data obtained at the start of the extraction period (Vincx, 1986); (2) data obtained from within the extraction period (Vanaverbeke et al, 2002) and (3) data obtained from the northern part of the Kwintebank where high intensity sand extraction was still ongoing.…”

We investigated short-term changes (two years) in nematode communities (density, diversity, biomass and community composition) in an area on the Kwintebank (Belgian Continental Shelf) that was closed for sand extraction activities and compared these patterns to nematode community characteristics from another area on the Kwintebank were sand extraction was still ongoing. Six stations were sampled in 2003 and 2004 and nematode community composition and univariate measures of diversity were compared with values obtained during the extraction period and with a "pre-impact situation" sampled in 1978. Although nematode density, diversity and biomass did not change two years after cessation of the exploitation, nematode community composition did and was more stable than in the extracted site. This is attributed to the absence of continuous disturbances associated with the extraction activities such as the creation and filling up of dredge furrows. As a consequence of the typical life history traits of nematodes, recovery seems to follow different pathways when compared to macrobenthic recovery from the same impact. (C) 2008 Elsevier Ltd.

“…For example, Vanaverbeke et al (2007) showed that sand extraction affected the nematode community at the base of the food web from the Kwinte sandbank (Southern Bight of the North Sea). Kaiser et al (2004) showed that sandbanks on the Welsh coastline (United Kingdom) hosted distinct fish assemblages foraging on benthic species colonizing the sandbanks.…”

Diversity and composition of macrobenthic community associated with sandy shoals of the Louisiana continental shelf

et al. 2009

Along the Louisiana, USA continental shelf, sandy shoals are shallow, possibly oxygen-rich ''islands'' surrounded by deeper muddy deposits prone to hypoxia. Shoals also contain significant quantities of fine sand that may be mined in the future for coastal restoration. The ecological role of shoals remains poorly understood and we hypothesized that shoals provide critical habitat for benthic invertebrates. Using Ship Shoal as a model system, we assessed the diversity and structure of macrobenthic assemblages and how community structure varies with season and environmental parameters. High biomass (averaging 26.7 g m -2 ) and high diversity (161 species) of macrobenthos was found in 2006. Polychaetes (45%-72 species) and crustaceans comprised most of the species (28%-46 species); spionids and amphipods dominated the polychaete and crustacean groups respectively, both in terms of number of species and abundances. Sharp decreases in diversity, abundance and biomass occurred from spring to autumn. Species diversity and total abundance significantly increased with decreasing sediment grain size and increasing bottom water dissolved oxygen. Across seasons, mole crabs Albunea paretii and amphioxus Branchiostoma floridae typified the community and contributed most of the biomass. The polychaetes Nephtys simoni, Neanthes micromma, Dispio uncinata, Mediomastus californiensis and Magelona sp. A, the amphipod Acanthohautorius sp. A and the burrowing shrimp Ogyrides alphaerostris also contributed to variation in community composition. Cluster analyses quantified seasonal variation, mainly based on sharp decreases in abundance, as well as spatial differences in species composition oriented along both eastwest and north-south gradients. Variation in benthic assemblages was correlated with
