“…A relevant difference is observed with only eight genera of bivalves found in this study with respect to 55 genera recorded in the subtropical Mazatlán Bay in Mexico [43]. 75% of the genera collected in TSB were gastropods; this high percentage has also been observed in Sinaloa coastal region where 70% of the species belong to this class [28], and according to Castillo-Rodríguez [44] the class Gastropoda is usually more diverse than Bivalvia.…”

This study describes the relationship between mollusks, physicochemical properties of seawater, and sediments under natural conditions of low impact. Thirty-nine stations were sampled in October 1994 using a Van Veen grab (0.1 m −2 ). Temperature, salinity, and dissolved oxygen (DO) concentrations of bottom water were obtained with a CTD. Organic matter content and sediment grain analysis were determined. A total of 836 mollusks were collected. Gastropoda was the most abundant (52%) and diverse class with 27 genera, followed by Bivalvia with eight genera and Scaphopoda with only one genus. According to CCA analysis, dominant mollusks were significantly related with high DO concentrations. Donax, Natica, Acteocina, Bulla, Anachis, Odostomia, and Crucibulum can be classified as sensitive genera because they were found mainly in high oxygen concentrations (3.1-5.6 mL L −1 ); on the other hand, Cardiomya, Nuculana, Laevicardium, Chione, Truncatella, and Dentalium can be classified as tolerant genera (1.0-5.6 mL L −1 ). Todos Santos Bay hosts a diverse malacological fauna (36 genera); our results show that the dominant genera were mainly related to high dissolved oxygen concentrations. Mollusks can be a useful tool in environmental monitoring programs related with oxygen depletion in coastal areas.

“…La estacionalidad parece no afectar notoriamente la abundancia y la rique-za de los moluscos según Ojeda et al (2014), ya que en su estudio los móviles tienden a aumentar ligeramente su densidad durante el verano austral y en los filtradores sésiles se mantienen casi constante y/o incluso registran su máxima abundancia en invierno. Otro factor importante por considerar para un inventario taxonómico es la sobreevaluación de macromoluscos (especies conspicuas), donde los micromoluscos (taxones menores de 10 mm) suelen ser ignorados debido a la dificultad que representa su determinación taxonómica (Esqueda-González et al 2014).…”

Riqueza y distribución vertical de los moluscos del litoral rocoso de la provincia de Islay, Arequipa, al sur del Perú

El litoral rocoso es un ecosistema heterogéneo en el que se distinguen una franja supralitoral, una zona mediolitoral y una franja infralitoral, al reconocer a las especies de moluscos como indicadoras de una zonación vertical. Este trabajo contribuye al conocimiento de la riqueza y la distribución vertical de los moluscos intermareales para la provincia de Islay, Arequipa, Perú. Se realizó una búsqueda intensiva en los meses de noviembre y diciembre del año 2013, para poder determinar la riqueza y se establecieron tres cuadrantes de 25 x 25 cm de lado distribuidos perpendicularmente a la línea costera con 14 repeticiones en los 7 sitios de estudio, para establecer su distribución vertical. Se utilizó un análisis de componentes principales (ACP), un escalamiento multidimensional no métrico (nMDS) y curvas de rango-abundancia para la determinación de la distribución vertical, y un análisis de similaridades (ANOSIM) para determinar diferencias entre la composición de moluscos entre los sitios de estudios y las subzonas del litoral. Se encontraron un total de 57 taxones, donde Echinolittorina peruviana fue la especie más representativa en la franja supralitoral, Perumytilus purpuratus para la zona mediolitoral y Tegula atra para la franja infralitoral. No se presentaron diferencias significativas en la composición de moluscos entre los sitios de estudio, pero sí entre las subzonas, al ser la zona mediolitoral la que presentó mayor riqueza y abundancia de organismos. La similitud fue mayor entre las subzonas medio e infra- con respecto a la supralitoral.

“…The Mexican Pacific coast has greater diversity of marine mollusks with 2567 species compared with a total of 2067 recorded together in the Gulf of Mexico and the Mexican Caribbean (Castillo-Rodríguez, 2014). However, most of the subtidal studies in the Mexican Pacific were carried out in soft bottoms (Martínez-Cordoba, 1996;Zamorano et al, 2007;Ríos-Jara et al, 2008, 2009Zamorano and Hendrickx, 2011;Hendrickx et al, 2014;Esqueda-González et al, 2014;Kuk-Dzul and Díaz-Castañeda, 2016), while the malacological description of subtidal hard bottoms has been a more recent undertaking (González-Medina et al, 2006;Landa-Jaime et al, 2013).…”

The objective of this study was to determine the structure of molluscan communities in shallow subtidal rocky bottoms of Acapulco, Mexico. Thirteen samplings were performed at 8 stations in 2012 (seven samplings), 2014 (four), and 2015 (two). The collection of the mollusks in each station was done at a maximum depth of 5 m for 1 h by 3 divers. A total of 2086 specimens belonging to 89 species, 36 families, and 3 classes of mollusks were identified. Gastropoda was the most diverse and abundant group. Calyptreaidae, Columbellidae, and Muricidae had >5 species, but Pisaniidae, Conidae, Fasciolariidae, and Muricidae had ≥15% of relative abundance. Most species found in this study were recorded in the rocky intertidal zone, and 10 species were restricted to the rocky subtidal zone. The affinity in the composition of the species during 2012-2015 had a low similarity (25%), but we could differentiate natural and anthropogenic effects according to malacological composition. In addition, 46% of the species recorded in this study are commercial fishing resources. We concluded that the rocky subtidal malacological fauna of Acapulco is highly diverse (89 species), and it has remained similar in space and time during this study.
