“…In the 537 present study, both species showed distinctive patterns. Even if both organisms were 538 able to develop mechanisms that allow their survival in the contaminated area of the 539 estuary (BAR), considering their high abundance in both areas (Piló et al 2015), they 540 seem to present different degrees of adaptation/acclimatisation. C. edule clearly 541 reflected the metal contamination in the sediments from both areas of study.…”

CitationPropensity edule. In the light of current findings, the information of C. edule as a bioindicator 47 should be complemented by that provided by another infaunal species under field 48 studies, since tolerance mechanisms to metals can hinder a correct diagnosis of 49 sediment contamination and the system's health. Overall, the present study contributed 50 to improve the lack of fundamental knowledge of two widespread and common 51 estuarine species, providing insights of the metal accumulation profiles under a 52 scenario of chronic contamination. Finally, this work provided useful information that 53 can be applied in the interpretation of future environmental monitoring studies. 54 3

Abstract. Anthropogenic warming and nutrient over-enrichment of our oceans have resulted in significant, and often catastrophic, reductions in dissolved oxygen (deoxygenation). Stress on water-breathing animals from this deoxygenation has been shown to occur at all levels of biological organization: cellular; organ; individual; species; population; community; and ecosystem. Most climate forecasts predict increases in ocean deoxygenation, thus it is essential to develop reliable biological indicators of oxygen stress that can be used by regional and global oxygen monitoring efforts to detect and assess the impacts of deoxygenation on ocean life. This review focuses on indicators of low-oxygen stress that are manifest at different levels of biological organization and at a variety of spatial and temporal scales. We compare particular attributes of these indicators to the dissolved oxygen threshold of response, time-scales of response, sensitive life stages and taxa, and the ability to scale the response to oxygen stress across levels of organization. Where there is available evidence, we discuss the interactions of other biological and abiotic stressors on the biological indicators of oxygen stress. We address the utility, confounding effects, and implementation of the biological indicators of oxygen stress for both research and societal applications. Our hope is that further refinement and dissemination of these oxygen stress indicators will provide more direct support for environmental managers, fisheries and mariculture scientists, conservation professionals, and policy makers to confront the challenges of ocean deoxygenation. An improved understanding of the sensitivity of different ocean species, communities and ecosystems to low oxygen stress will empower efforts to design monitoring programs, assess ecosystem health, develop management guidelines, track conditions, and detect low-oxygen events.

“…The macrobenthos is a key component of shallow marine ecosystems 23 , 24 , and biodiversity surveys are needed to examine spatial and temporal changes in community structure. Those changes, which may involve homogenization, local shifts in dominant fauna, or pollution gradients 2 , 6 , 7 , 25 , 26 , may indicate diverse ecosystem responses to variable anthropogenic pressures, particularly in coastal habitats. Assessments of regional ecosystem structuring may inform us as to the ecological impact of natural environmental drivers 11 , 22 , 27 , 28 and/or anthropogenic pressures 2 , 6 , 7 , 25 , 26 .…”

Despite its importance for quantifying ecosystem responses to environmental and anthropogenic drivers, our understanding of spatial heterogeneity in marine communities remains inadequate. Studies in coastal marine benthic habitats are sparse, and predominantly target single higher taxonomic groups. Here we describe macrobenthic marine invertebrate community surveys from 52 localities in Onslow Bay (Beaufort, North Carolina, U.S.A.), over an extensive geographic area (~200 km2). The data consist of 11,467 individuals, 175 species, and 7 phyla. The data include species abundance data for each sample at all localities, and corresponding species lists and locality information. The metadata describe the sampling protocols and localities. The data provided here will facilitate examination of assemblage heterogeneity with regards to spatial and temporal patterns, and depth gradient analyses.
