Abstract:

In shallow lakes, floating-leaved plants can produce dense lakebeds that dramatically alter freshwater ecosystems and impact macrobenthic communities. Shorebirds are morphologically diverse and utilize different foraging strategies; they can partition food resources to achieve coexistence due to differences in food availability. In this study, we defined shorebird foraging guilds using a principal component analysis and explained differences in shorebird composition in terms of food availability by comparing macrobenthic and shorebird communities in Euryale ferox artificial planting areas, Tra

Abstract:

Macrobenthic assemblages were examined in three fish estuarine nurseries and related to environmental variables, as well as fish and macrocrustaceans, in order to assess and compare the potential foraging ground value of these systems. Macrobenthos was sampled in spring 2007 in the Canche, Authie and Somme estuaries (eastern English Channel, France). A total of 17, 28 and 23 macrobenthic taxa, with a clear dominance of amphipods (mainly Bathyporeia sarsi), polychaetes and bivalves, were recorded in the three estuaries respectively. Although predators (fish and macrocrustaceans) were abundant,

Abstract:

The mass planting of mangroves has been proposed as a mitigation strategy to compensate for mangrove loss. However, the effects of mangrove vegetation on the abundance and community composition of macrobenthos remain controversial. The macrobenthic communities in four intact mangrove forests with different conditions and the adjacent nonvegetated mudflats of two mangrove species with distinct stand structures on the western coast of Taiwan were examined. Some macrobenthic taxa occurred only in the mangroves, suggesting macrobenthic critical habitats. Seasonal shift in community composition was

This pattern is indicative of disturbance, and results in dominance by trophic groups that live near the sediment–water interface (early benthic-community succession).

Abstract:

The paper presents the proportion of animals encountered in the coastal meiobenthos of Lake Krivoe (Karelia) which are typical for the majority of water bodies of the North-West of Russia: eumeiobentthic organisms – water mites, nematodes, cladocerans, harpacticoids, ostracods, benthic cyclops; organisms of pseudomeiobenthos – chironomids and oligochaetes. The main part in the biomass of meiobenthos in this zone accounts for water mites, chironomids and oligochaetes. In macrobenthos of this zone are registered: amphipods, larvae of caddis flies, mayfly larvae, larval Megaloptera, larval stonef

Abstract:

Human pressures have placed many tropical estuaries in developing countries under increased levels of stress. The Caroni Swamp Ramsar Site, the largest mangrove swamp along the west coast of Trinidad, has been subjected to high levels of anthropogenic impacts including hydrological alteration and pollution from land-based sources since the 1920’s. While most of these impacts have been well documented, limited information exists on the macrobenthic communities in the swamp. This study addresses the paucity of information. The macrobenthic fauna in the main waterways of Caroni Swamp was sampled

Abstract:

We assessed how multi- and univariate models reflect marine environmental health based on macrobenthic community responses to three environmental stressor categories: hydrodynamics, organic enrichment and metal contamination. We then compared the models with the benthic index AMBI (AZTI Marine Biotic Index). Macrobenthic community and physicochemical variables were sampled at 35 sites along Babitonga Bay, a subtropical estuary in Southern Brazil. Distance-based linear modelling identified depth, grain size and organic matter as well as Cu and Zn as key stressors affecting the macrobenthos. Usi

Abstract:

Sediment mud content is a significant predictor of macrobenthos abundance in marine soft-bottom habitats. However, the mechanisms behind the non-linearity generally shown in mud–macrobenthos relationships have not been examined. The present study analysed spatial distributions of sediment properties and macrobenthos in a tidal flat system of the north-east coast of Japan and tested the hypothesis: the non-linearity of mud–macrobenthos relationship corresponds to changes in bed elevation variability and sediment cohesiveness. For two macrobenthos species studied, Nuttallia olivacea (Bivalvia) a

About 108,000 macrobenthic specimens were collected, belonging to Oligochaeta (Naididae) (62%), Diptera (Chironomidae) (37%), and only 1.5% to other invertebrate taxa. Eighteen chironomid taxa were found.

In the first decade after zebra mussels (Dreissena polymorpha) appeared in the Hudson River, the biomass of zooplankton and deepwater macrobenthos fell by ∼50%, while the biomass of littoral macrobenthos rose by >10%. These changes in the forage base were associated with large, differential changes in the abundance, geographic distribution, and growth rates of openwater and littoral fish. In recent years, populations of zooplankton and deepwater macrobenthos have risen towards pre-invasion levels, while littoral macrobenthos remained unchanged.
