Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Bivalve genomics [PDF]

Aquaculture, 2006
Interest in bivalve genomics has emerged during the last decade, owing to the importance of these organisms in aquaculture and fisheries and to their role in marine environmental science. Knowledge of bivalve genome structure, function and evolution resulting from 20th century "single gene" approaches is limited, but genomic technologies are called to ...

Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

Environmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Massive populations of the non-indigenous bivalve species Electroma vexillum (Reeve, 1857) and its effects on native phytal benthic communities of tropical coastal reefs

Discover Oceans
The Vulsellidae is a family of marine bivalves distributed worldwide, with several species recognized as invasive. The present study reports, for the first time, a massive population of the vulsellid Electroma vexillum in macroalgae of coastal sandstone ...

Acute heat tolerance (CTmax) of two invasive parasitic copepods differs across species, life cycle stages and acclimation temperatures

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change is increasing the frequency and severity of heatwaves with potential consequences for host–parasite dynamics. While the acute heat tolerance of free‐living organisms has been intensively studied, much less is known about it for parasites and their life ...

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Analysis of microbial communities on the coloured mantle surface of three common bivalves

Aquaculture Reports
As economically significant species, bivalves maintain intimate contact with external microorganisms during respiration and filter feeding, rendering them prime candidates for investigating microbial communities.

Heavy metals in the clam Tivela mactroides Born, 1778 (Bivalvia: Veneridae) from coastal localities with different degrees of contamination in Venezuela

Ciencias Marinas, 2004
We compared heavy metal levels (manganese, iron, zinc, cadmium, copper, chromium, and lead) in tissues and shells of juveniles (13±2.2 mm), medium-size organisms with mature gonads (25±4.1mm), and adults (35±1.2 mm) of the clam Tivela mactroides from ...

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...
