“…In this study, we selected bivalve molluscs as typical nearshore animals having their economic importance and ecological relevance among macrobenthic animals [39,40]. Bivalves are often used as sentinel species or environmental indicators owing to their ability to accumulate chemical contaminants, lack of mobility, and wide distribution throughout the coastal waters of the world [41,42]. Moreover, bivalve molluscs have been described as a good target group for nanotoxicology because of their ability to feed on suspensions as well as their highly developed ability for the cellular internalization of nano and microparticles [29,43].…”

Nanoparticles (NPs) have broad applications in medicine, cosmetics, optics, catalysis, environmental purification, and other areas nowadays. With increasing annual production of NPs, the risks of their harmful influence on the environment and human health are also increasing. Currently, our knowledge about the mechanisms of the interaction between NPs and living organisms is limited. The marine species and their habitat environment are under continuous stress owing to the anthropogenic activities, which result in the release of NPs in the aquatic environment. We used a bioassay model with hemocytes of three bivalve mollusc species, namely, Crenomytilus grayanus, Modiolus modiolus, and Arca boucardi, to evaluate the toxicity of 10 different types of NPs. Specifically, we compared the cytotoxic effects and cell-membrane polarization changes in the hemocytes exposed to carbon nanotubes, carbon nanofibers, silicon nanotubes, cadmium and zinc sulfides, Au-NPs, and TiO2 NPs. Viability and the changes in hemocyte membrane polarization were measured by the flow cytometry method. The highest aquatic toxicity was registered for metal-based NPs, which caused cytotoxicity to the hemocytes of all the studied bivalve species. Our results also highlighted different sensitivities of the used tested mollusc species to specific NPs.

“…En ausencia de monitoreo ambiental, el estado de salud de las poblaciones de bivalvos y el conocimiento de la historia de vida de especies particulares, incluyendo la pérdida de la capacidad reproductiva, puede ser un indicador de alteraciones ambientales (Breton et al, 2018), donde los estudios de los factores que definen el sexo son útiles para reflejar la salud de los ecosistemas (Campos et al, 2012). Es así como, en Tegillarca granosa, después de 30 días de exposición a metales pesados (Cu, Zn, Pb y Cd), todos mostraron efectos significativos en la proporción de sexos, aumentando la cantidad de machos, además de reducir los valores del Índice Gonadosomático (Liu et al, 2014), y en Nicaragua se encontró que A. tuberculosa y Larkinia grandis tienen la capacidad de bioacumular metales en sus tejidos, por lo que recomiendan su uso como especies centinelas en los ecosistemas de manglares del Pacífico americano (Aguirre-Rubí et al, 2019).…”

Introducción: El bivalvo Anadara tuberculosa es un recurso pesquero y económico importante en el Pacífico Este Tropical. La proporción sexual varia a lo largo de su área de distribución, con casos de aparición de hermafroditismo, ocasional para algunas poblaciones, normal en otras. Estas características podrían ser una respuesta a presiones antropogénicas y ambientales. Objetivo: Evaluar la proporción sexual y el hermafroditismo en la especie en el Pacífico de Panamá. Métodos: Se analizó información reproductiva de A. tuberculosa generada entre 1994 y 2020 para el Golfo de Montijo, así como datos de 2017 para el manglar de David. Se aplicaron procedimientos macroscópicos, contrastados con histológicos y se generó un factor de corrección para ajustar la proporción sexual macroscópica, debido al efecto, sobre la proporción sexual, que ocasiona los organismos indeterminados. Resultados: Para el Golfo de Montijo, la histología indicó una proporción sexual hembra a macho de 1:1 hasta 3.2:1, entre 1994 y 2017, mientras que la macroscopía varió de 1.9:1 a 5.1:1 entre 2004 y 2020. Para el manglar de David, la histología indicó una proporción sexual de 3.7:1, y de 7.9:1 por macroscopía en el 2017. En ambas localidades, especímenes más grandes mostraron mayor variación en la proporción sexual, pese a la técnica implementada, así como hermafroditismo protándrico no casual en el 2017. Conclusiones: La aparición del hermafroditismo protándrico y los cambios en la proporción sexual indican que la población de A. tuberculosa, en ambas localidades, está respondiendo a presiones antropogénicas y ambientales.

“…The MCSI uses mangrove cover as a core indicator, which is also applied by the Mexican Mangrove Monitoring System (SMMM), but also is complemented by experts' opinions and rapid assessments at the mangrove communities. Still, different authors consider that cover is not sufficient to estimate the conservation [32,33], since it does not take into consideration other impacts on the ecosystems or the integrity of the ecological services they provided.…”

A Practical Index to Estimate Mangrove Conservation Status: The Forests from La Paz Bay, Mexico as a Case Study

et al. 2020

Mangrove cover has declined significantly in recent years in tropical and subtropical areas around the world. Under this scenario, it is necessary to elaborate and implement tools that allow us to make estimations on their conservation status and improve their protection and support decision-making. This study developed an index using qualitative and quantitative data. The criterions used in the index were: (1) Remnant Vegetation Index, (2) Delphi Method Survey, and (3) Rapid Assessment Questionnaire. In turn, the weights of the criterions were defined using the analytical hierarchy process (AHP). Once the values of each criterion were obtained, the index was applied to 17 mangrove communities located in La Paz Bay, Mexico. Finally, according to their score, they were classified based on the IUCN Red List of Ecosystems. The results show that five communities were ranked in the category Minor Concern, eight in Little Threatened, one in Vulnerable, one in Endangered, and two were classified as Deficiency of Data. These results are slightly different from other studies in the region and validate this index as a proper method. Therefore, it could be applied to other sites, especially in areas with little information and/or scarce monetary resources.
