Bivalve Response to Estuarine Eutrophication: The Balance between Enhanced Food Supply and Habitat Alterations
The net effect of eutrophication on bivalves depended on the balance between enhanced food supply and habitat alterations that are mediated by attributes of the receiving estuary, and differences among species, particularly feeding habits, feeding physiology, and tolerance to hypoxia.
Sublethal effects on reproduction in native fauna: are females more vulnerable to biological invasion?
This work shows that the widespread mat-forming invasive alga Caulerpa taxifolia (Vahl) C. Agardh has strong negative effects on the reproductive traits of a native bivalve Anadara trapezia even though the invader has positive effects on recruitment.
The functional role of burrowing bivalves in freshwater ecosystems
A clearer picture is needed of the importance of suspension versus deposit feeding and the potential advantages and tradeoffs between these two feeding modes, as well as the role of resource limitation in structuring bivalve communities.
Role of macrofauna functional traits and density in biogeochemical fluxes and bioturbation
The importance of different functional traits of macrobenthos in benthic processes of the Southern Bight of the North Sea was investigated to estimate the effects of density declines and species loss
Polychaete Richness and Abundance Enhanced in Anthropogenically Modified Estuaries Despite High Concentrations of Toxic Contaminants
The observed response of polychaetes was not a ‘positive’ response to toxic contamination or a reduction in biotic competition, but due to high levels of nutrients in heavily modified estuaries driving productivity in the water column and enriching the sediment over large spatial scales, which suggests differences observed in the survey are related to parameters that covary with estuary modification.
Size matters: implications of the loss of large individuals for ecosystem function
By manipulating bivalve size structure through the removal of large individuals, this work held species identity constant, but altered the trait characteristics of the community, and the number of large bivalves was the best predictor of ecosystem functioning.
Anoxic survival potential of bivalves: (arte)facts.
The combined influence of body size and density on cohesive sediment resuspension by bioturbators
By relating the biota-mediated changes in resuspended sediment to metabolism, this work can place the observations within the broader context of the metabolic theory of ecology and formulate general expectations about changes in biota'smediated sediment resuspension in response to changes in population structure and climate change.
Native species behaviour mitigates the impact of habitat-forming invasive seaweed
Pop-up in Caulerpa allowed similar survivorship to that in unvegetated sediment; however, when Anadara was prevented from popping-up, they suffered >50% mortality in just 1 month; these findings not only highlight the substantial environmental alteration by Caulers, but also an important role for the behaviour of native species in mitigating the effects of habitat-forming invasive species.
