This paper proposes probable <em>Pterois</em> spp invasion areas on the western coast of Mexico, based on ecological niche and potential distribution models, as well as species occurrence data (1985-2018) and environmental layers (2002-2017). For the environmental database, rasters of temperature, salinity, chlorophyll <em>a</em> and velocity of sea currents were used at average, maximum, and minimum values at the surface level, as well as average temperature and salinity at the seabed level and the type of predominant coast. Results indicated that bottom salinity, type of coast, and average surface temperature contributed 65% to the distribution model. To learn the impact of the possible invasion of <em>Pterois</em> spp. on local biodiversity, a spatial intersection was made between the predicted area with potential for invasion with the geographic distribution of coastal fish and the fishing areas. According to the spatial analysis, the arrival of <em>Pterois</em> spp. could affect almost 200 species, several of which are endemic and of commercial importance. The impact could be even greater, considering that the species is a predator of invertebrates such as crayfish and shrimp, which are important fisheries in the region.</p> Héctor Reyes-Bonilla David Petatán-Ramírez ##submission.copyrightStatement## 2020-10-20 2020-10-20 9 26 10.15359/revmar.12-2.1 Spatio-temporal variation on the ecological structure of the fish community in the Ostión Lagoon, Veracruz, Mexico <p>Although the fish community in the Ostión Lagoon is subject to fishing, ecological studies on it are scarce. The spatial and temporal variation of this community structure was analyzed, as well as the physicochemical parameters of the lagoon’s salinity, temperature, dissolved oxygen, depth, and transparency. Samples were collected bimonthly from March 2007 to January 2008 in eight sampling stations with a shrimp trawl. Significant spatial and temporal differences were evaluated in diversity, richness, evenness, density, biomass, and average weight through analysis of variance. A canonical correspondence analysis (CCA) was used to determine fish associations and their correlation with the environmental factors of the system. A total of 737 individuals were collected with a total weight of 19,081.90 g. The study identified 19 families, 23 genera, and 34 species, of which 12 were new records for the lagoon. Four species were found to be dominant in the system. Community parameters showed a relationship with environmental gradients and climatic seasons. Diversity was higher in May (H´= 2.36) and January (H´ = 2.48), while density was higher in July (0.018 ind./m<sup>2</sup>). The CCA showed that the composition and spatio-temporal distribution of the fish community was conditioned by salinity, temperature, dissolved oxygen, and depth. Knowing the fish’s community structure and biological functions and their interaction with environmental factors in this lagoon is relevant since ongoing studies have not been conducted for this system.</p> Arturo Aguirre-León Silvia Díaz-Ruiz Mariela Gazca-Castro ##submission.copyrightStatement## 2020-10-20 2020-10-20 29 55 10.15359/revmar.12-2.2 Trace metals (Fe, Mn, Zn, Cu) in the polychaete Americonuphis reesei (Class: Polychaeta), in El Salado Beach, Aguadulce, Panamá <p>The concentration of the heavy metals Fe, Mn, Zn, and Cu was determined in a homogenized sample of the polychaete <em>Americonuphis reesei</em> tissue in three sampling stations in Playa El Salado, Parita Bay, during the dry season in 2017. Three sampling locations were established at each station, 50 m apart from each other. Samples were digested with nitric acid, and metal concentration was determined by atomic absorption spectrophotometry. The highest concentration recorded was Fe, with an average of 581.98 µg·gˉ¹, followed by Mn with 25.71 µg·gˉ¹. The lowest values were reported for Zn, 16.05 µg·gˉ¹ and Cu, 3.52 µg·gˉ¹. A significant correlation was found between Fe and Mn (r = 0.95) and Mn and Cu (r = 0.71) <em>P</em> &lt;0.01 as well as a highly significant correlation between Fe and Cu (r = 0.64) <em>P</em> &lt;0.002. The sizes of polychaetes in stations 1 (Rio Santa María) and 3 (Palo Blanco) show no significant differences; however, sizes in station 2 (El Playón) showed differences compared to the other two stations. No correlation was found between length and metal concentration. Metal concentrations between the stations indicate that there is a significant difference in Mn and Fe in stations 1 and 3, and in Fe between stations 1 and 2. Metals detected in the tissue do not pose any risk since the concentrations are below the values of the established standards.</p> Diana Rodríguez Janzel R.
