Crassostrea Corteziensis

SummaryThe aim of this investigation was to identify the parasites present in the largely understudied pleasure oyster Crassostrea corteziensis in Sinaloa state in the northwestern Mexican Pacific coast. Inspection of twenty-eight oysters collected on “Ceuta” lagoon revealed the presence of the digenean Stephanostomum sp. (Digenea: Acanthocolpidae) cysts. Metacercariae were found encapsulated and embedded in the digestive gland and mantle tissue of oysters. The prevalence of infection revealed that 84.6 % were infected, the abundance was 13.62, with a mean intensity of 16.09 per host. The members of this genus are characterized by a double crown of spines in the cephalic region surrounding the buccal opening of the worm. Significantly, we report the first incidence of the digenean Stephanostomum sp of the family Acanthocolpidae parasitizing Crassostrea corteziensis. Further we report that this bivalve is now considered a new intermediate host, and the northwestern Mexican Pacific coast is a new geographical distribution area for this digenean. The findings contribute to our understanding of the biology, biodiversity and host preference of these parasites, with implications for health risks posed by human consumption of the pleasure oyster.

A New Species

Chalinidae is a family of haplosclerid sponges with a delicate reticulated chaonosomal skeleton of uni-, pauci- or multispicular primary lines which are connected by unispicular secondary lines, and with an ectosomal skeleton, if present, formed by a regular hexagonal, unispicular, tangential reticulation (Weerdt 2002). Currently, the family harbors only five valid genera (Chalinula, Cladocroce, Dendrectilla, Dendroxea and Haliclona; Soest et al. 2008), although recent molecular studies suggest that a new rearrangement of the present classification is needed (Redmond et al. 2007). Cladocroce was described by Topsent (1892) from specimens collected in the Atlantic Ocean. The principal characteristic of this genus is the presence of multispicular fiber tracts with a rather dense subisotropic reticulation in between (Weerdt 2002). After that, 10 species have been described, most of them from deep waters and cold climates (Putchakarn et al. 2004). Only three species have been found living in shallow waters: C. aculeata Pulitzer-Finali, 1982 from the Great Barrier Reef, C. burapha Putchakarn et al., 2004 from the Gulf of Thailand, and C. tubulosa Pulitzer-Finali, 1993 from the port of Mombasa, in Kenya. Sponge taxonomy studies in the Mexican Pacific coast have been focused mainly on hadromerids, and particularly on boring sponges (Carballo et al. 2008), and the current knowledge of haplosclerids is very scarce (Cruz-Barraza & Carballo 2006). In this paper, a new species of Cladocroce is described and compared with the other species recorded worldwide. With this contribution the genus Cladocroce increases to 12 species.

Natural Time

One of the most important subduction zones in the world is located in the Mexican Pacific Coast, where the Cocos plate inserts beneath the North American plate. One part of it is located in the Mexican Pacific Coast, where the Cocos plate inserts beneath the North American plate with different dip angles, showing important seismicity. Under the central Mexican area, such a dip angle becomes practically horizontal and such an area is known as flat slab. An earthquake of magnitude M7.1 occurred on 19 September 2017, the epicenter of which was located in this flat slab. It caused important human and material losses of urban communities including a large area of Mexico City. The seismicity recorded in the flat slab region is analyzed here in natural time from 1995 until the occurrence of this M7.1 earthquake in 2017 by studying the entropy change under time reversal and the variability β of the order parameter of seismicity as well as characterize the risk of an impending earthquake by applying the nowcasting method. The entropy change ΔS under time reversal minimizes on 21 June 2017 that is almost one week after the observation of such a minimum in the Chiapas region where a magnitude M8.2 earthquake took place on 7 September 2017 being Mexico’s largest quake in more than a century. A minimum of β was also observed during the period February–March 2017. Moreover, we show that, after the minimum of ΔS, the order parameter of seismicity starts diminishing, thus approaching gradually the critical value 0.070 around the end of August and the beginning of September 2017, which signals that a strong earthquake is anticipated shortly in the flat slab.

First Time

Knowledge about the sponge fauna from the Mexican Pacific Ocean has increased substantially in recent years, but most of these modern taxonomic studies have been focused on hadromerids. The aim of this study was to contribute to the knowledge of the order Poecilosclerida. At present, seven species of Mycale have been described or recorded from the Pacific coast of Mexico, but only three of them are considered valid: M. contax, M. cecilia and M. aff. magnirhaphidifera. After a revision of the material collected during the last eight years throughout the East Pacific coast of Mexico, along with the type material, and the literature available, eight species of Mycale are considered valid, three of them; M. magnitoxa sp. nov., M. dickinsoni sp. nov., and M. ramulosa sp. nov., are proposed as new to science. In addition, M. adhaerens is reported for the first time from the Mexican Pacific Ocean. Another Mycale-species that was identified was M. psila, which constitutes its seconLamberd record for the Mexican Pacific Ocean. The systematic, distribution and detailed species descriptions are based on newly collected material and previous descriptions from the literature.
