“…In addition, clams from SL displayed most of the alteration indicators at levels that were intermediate between those for SR and the control site. This finding confirms that mining pollution partially extends to SL, as reported by Muñoz-Barbosa and Huerta-Díaz ( 2013), although with a lower impact on the reproductive health of species, as reported by Yee-Duarte et al (2020) for M. squalida.…”

Objective Prolonged exposure to heavy metals, such as Pb, Hg, or Cu, has multiple adverse effects on marine organisms at the cellular, physiological, and population levels. Bivalves' histopathology provides a sensitive biomarker of pollutant‐induced stress and environmental health. Gonad tissue deterioration is of particular concern, as it affects the reproductive success of a species. This study aimed to examine the histopathological alterations caused by metal exposure in the gonad of the white clam Dosinia ponderosa. Methods Organisms were sampled from three locations in the Gulf of California: Santa Rosalia (SR), a former Cu mining town; San Lucas beach (SL), a nearby site influenced by pollution; and Escondida beach (EB), which served as a control site. Histological and histochemical stains were used, and the prevalence and intensity level of each alteration were calculated. Result The prevalence of alterations was higher in the ovaries of SR clams (92% compared to 60% in SL clams and 32.7% in EB clams), during spawning (91.4% compared to 20% in SL clams and 4.7% in EB clams), and in winter (93.5% compared to 30% in SL clams and 17.4% in EB clams). Conclusion These findings suggest a significant deterioration in the gonads of white clams from SR, probably linked to the chronic exposure to high concentrations of Cu and possibly other heavy metals; hence, the reproductive health of the clams is likely compromised.

“…According to these authors, metals and metalloids (mining activities), nutrients and pesticides (shrimp farming or intensive agricultural discharges) are the main sources of pollution having toxic effects on marine organism (Páez‐Osuna et al., 2017; Ribeiro‐Prado et al., 2008; Vezzone et al., 2019). Within the Gulf of California, Santa Rosalia, Baja California Sur, stands out for its historical mining activities (Roldán‐Wong et al, 2018; Yee‐Duarte et al., 2020) reporting anomalies such as xanthism in Mycteroperca rosacea (Irigoyen‐Arredondo et al., 2017) and histopathological alteration in Megapitaria squalida (Yee‐Duarte et al., 2018). These anomalous specimens have a home range quite restricted to Santa Rosalia, when compared with the motility of the batomorphs.…”

Although morphological abnormalities in several rays and skate species around the American continents have frequently mentioned, their numbers are unknown. The present work record morphological abnormalities in four Urotrygonidae species. Two anophthalmic specimens were detected (Urotrygon microphthalmum and Urobatis halleri). Two individuals lacked caudal fins (Urobatis maculatus and Urotrygon chilensis). Two round rays showed incomplete fusion of the pectoral fin to the head (U. microphthalmum and U. chilensis). Vertebral compression and fusion were found in a 6‐year‐old female Urotrygon rogersi. In addition, 118 abnormal batomorph specimens were gathered from the available bibliography, spanning the last six decades (1959–2021). Amblyraja doellojuradoi was the species with the highest number of abnormalities (18). The most common anomaly was an incomplete fusion of the pectoral fin with the head. Since 2010, at least 30 anomalous batomorphs have been recorded every 5 years. Sixty‐nine abnormal specimens occurred in the Northern Hemisphere (1.00–60.00 N). The Cortezian (Pacific) and Southeastern Brazil (Atlantic) marine ecoregions stood out with the highest number of these specimens. Mexico recorded 58 anomalous specimens, followed by Brazil (n = 36). Biological, abiotic and anthropogenic factors are probably the leading causes. However, additional studies are necessary to elucidate these speculations.

“…El contenido de Calcio y Magnesio, contenido en más del 50 % de las muestras, se atribuye al origen geológico de la provincia Sierra Madre del Sur. Tal como lo observaron recientemente, Camacho et al (2020), en donde aproximadamente el 72 % de las aguas estudiadas en la misma red hidrográfica, fueron bicarbonatadas magnésicas-cálcicas. Los cationes Ca y Mg, provienen de la intemperización de las calizas y dolomías del Cretácico, material geológico del cual están conformadas las montañas de la Sierra Madre del Sur (Velázquez & Ordaz, 1992).…”

Benitez RESUMENAntecedentes. En el Golfo de México, el Sistema Lagunar de Alvarado (SLA) destaca por sus dimensiones y pesquerías. Los rotíferos están entre los grupos más abundantes del zooplancton en estos ecosistemas. La información sobre su composición y dinámica estacional es escasa a pesar de su importancia estructural y funcional. Objetivos. Evaluamos la diversidad, variación estacional e influencia del pH, transparencia, salinidad y temperatura sobre la estructura de las comunidades de rotíferos en el SLA. Métodos. Se recolectaron muestras de zooplancton y se registraron parámetros fisicoquímicos durante septiembre 2017 a mayo 2018, en distintas épocas climáticas en cuatro zonas del SLA según el gradiente de salinidad. El zooplancton fue separado por grupos y los rotíferos se identificaron hasta especie. Se estimaron índices de Shannon-Weiner y diversidad efectiva calculando números de Hill Q1 y Q2, analizando diferencias entre zonas y temporadas. Se realizó análisis de conglomerados para determinar similitudes en la composición biológica entre diferentes zonas y temporadas. Se realizó el análisis de correspondencia canónica transformando datos de parámetros fisicoquímicos y abundancia de especies de rotíferos. Resultados. Se observó comportamiento oligohalino en lluvias a mesohalino en secas y la gran influencia de ríos durante lluvias en todo el SLA. Se identificaron 24 especies de rotíferos y cuatro especies de cladóceros, todos nuevos registros, siendo la familia Brachionidae la más abundante. La mayor diversidad ocurre en la zona sur en lluvias y la menor en nortes. La salinidad y transparencia estuvieron relacionadas con la distribución de las especies de Brachionidae. Conclusiones. El comportamiento hidrológico y variabilidad del gradiente de salinidad concuerda con lo reportado para el SLA.
