“…Although Maldanidae (Axiothella) were present in these conditions, their density was much lower than that recorded in the control. Concerning Capitellidae and Spionidae, various species have been widely defined as indicators of organic enrichment (Pearson and Rosenberg 1978;Rivero et al 2005;Ferrando et al 2010Ferrando et al , 2015Ferrando et al , 2019. In this study, the response of the Spionidae was different according to the genera.…”

“…Caleta Sara was selected for this study due to its predominance of fine sediments, low trace metal content, presence of biogenic hydrocarbons and high biodiversity of macrobenthic assemblages (Ferrando 2015). Although this study describes these assemblages in relation to the environmental characteristics of the Gulf of San Jorge, little is known about assessing the impact of crude oil on these environments (Ferrando et al 2015(Ferrando et al , 2019.…”

“…Due to their typically high species richness and abundance in benthic environments, polychaetes play a fundamental ecological role (Venturini et al 2011). Moreover, they exhibit different degrees of stress tolerance (Pearson and Rosenberg 1978;Dauvin et al 2010;Ferrando et al 2019; among others). Marrero et al (2013), working with the assemblage of Polychaeta in the Rio de la Plata estuary, has shown that the family level is the most appropriate compromise between reducing the cost of identification and the efficiency of statistical results.…”

“…The anthropogenic introduction of hydrocarbons into marine ecosystems can result from large crude oil spills, as well as smaller discharges from fishing activities, urban and industrial effluents, bilge and ballast water from ships (Commendatore and Esteves 2007). In both cases, the effects on the habitat and biota are significant (Lindgren et al 2014;Ferrando et al 2015Ferrando et al , 2019. Crude oil is considered problematic to organisms due to its toxicity, carcinogenicity and mutagenicity (Christensen et al 2002) and can negatively affect different marine organisms in their diet, growth and reproduction at different trophic levels (Alonso-Alvarez et al 2007;Almeda et al 2013).…”

Una de las herramientas aplicadas para determinar el estado de contaminación y estrés de un ambiente es a través de bioindicadores macrobentónicos. Los objetivos de este estudio fueron 1) validar condiciones experimentales ex situ comparando después de 13 días, diferentes variables fisicoquímicas y biológicas entre tratamientos in situ y ex situ; 2) analizar, a través de un experimento ex situ, el efecto producido por dos concentraciones de petróleo crudo (1 g/kg y 20 g/kg) sobre los ensamblajes de poliquetos de Caleta Sara a diferentes profundidades de la columna sedimentaria (0-8 cm y 8-16 cm), y 3) evaluar la aplicación del concepto de suficiencia taxonómica a los datos del experimento con petróleo crudo. La riqueza, la diversidad, la abundancia y la bioturbación disminuyeron significativamente en los sedimentos contaminados con petróleo solo en el nivel superior. Capitella (Capitellidae) y Boccardia (Spionidae) fueron los más abundantes en la concentración más alta de petróleo. Los resultados a ambos niveles taxonómicos fueron similares, indicando que se podría determinar el efecto del petróleo crudo a nivel de familia, sobre todo si las condiciones ecotoxicológicas son agudas. Sin embargo, la relación familias:géneros fue 1:1 en todos los casos, excepto para Spionidae. Por lo tanto, la identificación a nivel de familia debería ser considerada solo para ensamblajes de poliquetos poco diversos. Este estudio es el primero que evalúa en laboratorio los ensamblajes de poliquetos de Caleta Sara en condiciones modificadas por el petróleo crudo. De este modo, se simulan las condiciones naturales y se evita todo impacto negativo en el sitio de estudio.

“…Agustina, Emilia, Catalina, and Luis (2019) measured spinoid polychaete abundance at different depths of field‐collected benthic sediment to assess oil‐induced stress caused by low (1 g/kg) and high (20 g/kg) concentrations of Escalante crude oil. The laboratory experiment consisted of sediment cores and water samples collected from the field in San Jorge Gulf, Argentina.…”

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.
