“…Anthropogenic inputs are detected in both NW and SE regions, increasing organic matter inputs. It has previously been reported that the presence of diverse hydrocarbons in NW GoM is due to various factors, especially to the organic material discharged by the Laguna Madre, Bravo, Soto La Marina and Pánuco rivers, which contribute to the complex mixture of organic compounds that accumulate in the marine sediments ( Macdonald et al, 2015 ; Aguilera et al, 2019 ). Bacterial taxonomic profiles only showed significant differences for deep and shallow sediments and it was not possible to see the differences between NW and SE regions that the whole-metagenome data showed.…”

The Gulf of Mexico (GoM) is a particular environment that is continuously exposed to hydrocarbon compounds that may influence the microbial community composition. We carried out a metagenomic assessment of the bacterial community to get an overall view of this geographical zone. We analyzed both taxonomic and metabolic markers profiles to explain how the indigenous GoM microorganims participate in the biogeochemical cycling. Two geographically distant regions in the GoM, one in the north-west (NW) and one in the south-east (SE) of the GoM were analyzed and showed differences in their microbial composition and metabolic potential. These differences provide evidence the delicate equilibrium that sustains microbial communities and biogeochemical cycles. Based on the taxonomy and gene groups, the NW are more oxic sediments than SE ones, which have anaerobic conditions. Both water and sediments show the expected sulfur, nitrogen, and hydrocarbon metabolism genes, with particularly high diversity of the hydrocarbon-degrading ones. Accordingly, many of the assigned genera were associated with hydrocarbon degradation processes, Nitrospira and Sva0081 were the most abundant in sediments, while Vibrio , Alteromonas , and Alcanivorax were mostly detected in water samples. This basal-state analysis presents the GoM as a potential source of aerobic and anaerobic hydrocarbon degradation genes important for the ecological dynamics of hydrocarbons and the potential use for water and sediment bioremediation processes.

“…In the Tamaulipas Laguna Madre, the Gulf of Mexico, the use of a wide-ranging battery of biochemical biomarkers (acetylcholinesterase, butyrylcholinesterase, carboxylesterase, alkaline phosphatase, glutathione s-transferase, oxygen radical absorbance capacity) analyzed on the clam Chione elevata as a sentinel organism was integrated into a stress index, the Integrated Biomarker Response (IBR), and complemented by the chemical analysis of metals, organochlorine pesticides, and hydrocarbons in the sediments [60]. The authors underlined the potential of the approach to be a useful tool for monitoring the health status of the sentinel organisms and, in turn, the environmental quality of the MPA.…”

Marine biodiversity is threatened by several anthropogenic pressures. Pollution deriving from the discharge of chemical contaminants in the sea represents one of the main threats to the marine environment, influencing the health of organisms, their ability to recover their homeostatic status, and in turn endangering biodiversity. Molecular and cellular responses to chemical pollutants, known as biomarkers, are effect-based methodologies useful for detecting exposure and for assessing the effects of pollutants on biota in environmental monitoring. The present review analyzes and discusses the recent literature on the use of biomarkers in the framework of biodiversity conservation. The study shows that pollution biomarkers can be useful tools for monitoring and assessment of pollution threat to marine biodiversity, both in the environmental quality monitoring of protected areas and the assessment of the health status of species at risk. Moreover, key areas of the research that need further development are suggested, such as the development of omics-based biomarkers specifically addressed to conservation purposes and their validation in the field, the extension of the biomarker study to a wider number of endangered species, and the development of organic guidelines for the application of the biomarker approach in support to conservation policies and management.

“…Recreational activities, including beach visits and SCUBA diving, were assessed for impacts to several different types of marine organisms. Tire ruts from vehicles driving on beaches of Boa Vista Island, Cape Verde were experimentally found to increase the frequency of disorientation, misorientation, and crawl time in newly hatched loggerhead sea turtles ( Caretta caretta ) (Aguilera, Leija, Torres, & Mendoza, 2019; Aguilera, Medina‐Suarez, et al, 2019). While, the density of human occupancy at tourist beaches near Rio de Janeiro, Brazil did not result in significantly different nematode biological indexes (average number of genera per sample, Shannon index, Pielou’s evenness, and rarefaction index) compared to beaches that are less affected by human presence (Santos, Cardoso, & Maria, 2019).…”

“…The timing of response (during vs. post dredging) was species dependent for EROD and GST. Aguilera, Leija, et al (2019), Aguilera, Medina‐Suarez, et al (2019)) collected clams ( Chione elevata ) from four locations in Laguna Madre, Mexico. AChE, butyrylcholinesterase (BChE), carboxylesterase (CbE, all neurotoxicity biomarkers), alkaline phosphatase (ALP, inflammation) and GST activity and cellular antioxidant capacity were incorporated into an Integrated Biomarker Response (IBR) index to determine the relative health of clams at the four sites.…”

This review covers selected 2019 articles on the biological effects of pollutants, including human physical disturbances, on marine and estuarine plants, animals, ecosystems, and habitats. The review, based largely on journal articles, covers field, and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing, and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, marine debris, dredging, and disposal. Special emphasis is placed on effects of oil spills and marine debris due largely to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and proliferation of data on the assimilation and effects of marine debris microparticulates. Several topical areas reviewed in the past (e.g., mass mortalities ocean acidification) were dropped this year. The focus of this review is on effects, not on pollutant sources, chemistry, fate, or transport. There is considerable overlap across subject areas (e.g., some bioaccumulation data may be appeared in other topical categories such as effects of wastewater discharges, or biomarker studies appearing in oil toxicity literature). Therefore, we strongly urge readers to use keyword searching of the text and references to locate related but distributed information. Although nearly 400 papers are cited, these now represent a fraction of the literature on these subjects. Use this review mainly as a starting point. And please consult the original papers before citing them.
