“…Hence, three main zones represented by the lagoon basins can be defined. Despite the ecological importance of the lagoon as part of a Biosphere Reserve, macrobenthos has barely been studied, and only one study including polychaetes information has been published from Río Lagartos (Kuk-Dzul, Gold-Bouchot, & Ardisson, 2012). In this study, low abundance and species richness was detected in the eastern hypersaline basin (i.e.…”

Introduction: The Río Lagartos lagoon, located in the Ría Lagartos Biosphere Reserve, Yucatán, Gulf of Mexico, is a coastal hypersaline system ca. 80 km long (east-west). It comprises three basins: western (close to Río Lagartos fishermen village), middle (Las Coloradas) and eastern (close to El Cuyo fishermen village), that communicate through very narrow natural channels. Despite several studies have been performed on the vertebrate fauna, the aquatic invertebrates, and especially polychaetes, remain largely unknown. Objective: The objective of this study is to describe the composition and distribution of the benthic polychaete community, and to analyse potential environmental drivers. Methods: The biological material was collected in 16 stations distributed along the lagoon during the rainy season (September 2017). Two replicates per station were obtained using a Ponar standard dredge or cores (6” diameter). Environmental variables such as grain size, organic carbon content in the sediments, and salinity, among others, were measured. Results: A total of 827 specimens belonging to 26 species and 16 families were identified. Of these, 23 species are new records for the Río Lagartos lagoon. Community composition changed between the different basins associated with strong gradients in salinity, subaquatic vegetation (algae and seagrasses) proportions in the samples and grain size. No polychaetes were recorded at the easternmost basin (El Cuyo basin), where salinity was between 67-80 psu. In the rest of the lagoon, the distribution of polychaetes was heterogeneous, especially near the mouth (western basin), where the highest and lowest density, species richness and diversity were recorded. The highest density was found at station 6, where dense algal mats of the genus Avrainvillea dominated. The families Syllidae and Nereididae were the most abundant and widely distributed families in the lagoon. The species Syllis lagunae and Nereis pelagica dominated the western basin and Prionospio heterobranchia and Sphaerosyllis taylori dominated the middle basin. Conclusions: The salinity records associated with some species were well above the top limits previously reported, establishing the euryhaline character of many species in the region.

“…Some differences detected between the cruises were probably caused by differences between years and periods (between 2011-2012 and 2015-2016). Although seasonal variations in the coastal and shallow regions of the YCS are usually associated with continental run-off, wind stress and sea surface temperature (Hernández-Arana et al, 2003;Hernández-Guevara, Pech & Ardisson, 2008;Kuk-Dzul, Gold-Bouchot & Ardisson, 2012), climatic variations generate oceanographic conditions that can affect deeper waters. The oceanographic conditions of the Southern GoM during the rainy season include low wind stress (<5 m s −1 ), low mixed layer depth (<40 m) and low net primary production (<250 mg C m −2 day −1 ), while cold front conditions include high wind stress (>6 m s −1 ), a greater mixed layer depth (>80 m) and high primary productivity (>350 mgC m −2 day −1 ) (Müller-Karger et al, 2015).…”

Different hypotheses related to the regional-scale configuration of the Yucatan Continental Shelf (YCS) between the Gulf of Mexico (GoM) and the Caribbean Sea have been proposed. Hypotheses regarding its regional boundaries include: (i) an ecoregional boundary at Catoche Cape, dividing the Western Caribbean and the Southern GoM ecoregions; and (ii) a boundary within the Southern GoM ecoregion at 89°W, separating the West and Mid-Yucatan areas. We tested the hypothesis of no variation in benthic macrofaunal assemblages between regions delimited by the former boundaries using the species and functional traits of soft-bottom macrofauna. We considered that the depth and temporal environmental dynamics might interact with regional variations, generating complex benthic community patterns. The data were collected over five years (2010–2012, 2015–2016) at 86 stations (N = 1, 017 samples, 10–270 m depth), comprising 1,327 species with 45 combinations of functional traits. The variation in species composition and functional trait assemblages were both consistent with the occurrence of three separate regions in the Yucatan Peninsula (West Yucatan, Mid-Yucatan and Western Caribbean). This regional configuration was consistent with changes in assemblage structure and depth zonation as well as temporal variation. Along with spatial and temporal variation, diversity diminished with depth and different regions exhibited contrasting patterns in this regard. Our results suggest that the spatial and temporal variation of soft-bottom macrofauna at YCS demonstrate the complex organization of a carbonate shelf encompassing different regions, which may represent transitional regions between the Caribbean and the GoM.

“…Meador and Rice (2001) used the opheliid Armandia brevis, typical of temperate environments, to evaluate the toxic effects of tributyltin (TBT). For tropical environments another species from the same genus, Armandia agilis, has a high abundance along the Brazilian coast (Amaral, 1980;Amaral et al, 2010;Amaral and Borzone, 2008;Kuk-Dzul et al, 2012;Omena et al, 2012;Silva, 2007;Venturini et al, 2008) and could be considered a potential test organism for sediment toxicity tests.…”

Sediments constitute a key compartment of coastal and marine ecosystems. They also constitute the ultimate sink for most of the chemical substances and a source of contamination to the benthic fauna. In this study, we aimed to develop a protocol for acute toxicity tests using the polychaete Armandia agilis as a model species. To achieve that, we evaluated the species tolerance to the salinity of overlying water (in the presence and absence of sediment), the tolerance to sediments with different particle sizes, the sensitivity to reference substances (potassium dichromate-K 2 Cr 2 O 7 , zinc sulfate-ZnSO 4 ; and Sodium Dodecyl Sulfate-SDS), and the responses to clean and contaminated sediments. The species survives in several latitudes on the American coast (North Carolina, Gulf of Mexico, and South-Southeast of Brazil) in different haline conditions (above 20) in typically sandy textures. In Ilhabela (SE Brazil), the species was available throughout the year. The LC 50-48h values calculated to the K 2 Cr 2 O 7 , ZnSO 4 , and SDS, were 20.94 (33.38-14.04); 4.25 (7.66-2.98); 4.90 (6.59-3.84) mg L-1 respectively; thus A. agilis can be considered as sensitive as other benthic organisms. The responses of A. agilis to environmental sediments were similar to those exhibited by the amphipod Tiburonella viscana, showing that this polychaete is responsive to contaminated sediments. Armandia agilis can be considered a promising organism to be used in sediment toxicity tests.
