Effects of combined rising sea temperature and increasing sea level on coral reefs, both factors associated with global warming, have rarely been addressed. In this ~40 y study of shallow reefs in the eastern Indian Ocean, we show that a rising relative sea level, currently estimated at ~11 mm y−1, has not only promoted coral cover but also has pot...
Scallops are bivalve filter-feeding mollusks that can attain a large size and have great importance in terms of their ecological roles and commercial value. Overfishing has led to a decrease in scallop stocks worldwide, leading to intense development of the aquaculture industry. The latter is well-established in Asian countries in the East Sea and...
Road-salt pollution in streams in the Northeastern United States has become a major concern, but historical data are scarce. Freshwater bivalve shells have the ability to record past environmental information, and may act as archives of road-salt pollution. We sampled Elliptio complanata shells from four streams, as well as specimens collected in 1...

El presente trabajo aporta nuevos registros de babosas marinas observadas en cuatro localidades de la zona norte de Veracruz: arrecife Enmedio, arrecife Lobos, espigones de Tuxpan y laguna Tampamachoco; los avistamientos se realizaron entre julio 2022 y marzo 2024. En total se identificaron 12 especies de babosas marinas, de las cuales, tres especies son nuevos registros para el sur del golfo de México, y cuatro son nuevos registros para la zona norte de Veracruz. Estos registros contribuyen al conocimiento de las babosas marinas en el sur del golfo de México, la cual se ha incrementado favorablemente en años recientes.
... While sampling in Arcas, Verde and PM took place from March to August, it is unlikely that seasonal variability in environmental factors are responsible for the differences in sea slug abundance found between the reefs. Differences in temperature and photoperiod, which have been signaled as important factors regulating sea slug temperate populations (Clark 1975;Mondy and Pierce 2005), are less extreme in tropical than in temperate waters, and E. crispata occurs almost all year around in coral reefs of the Southern Gulf of Mexico and Mexican Caribbean (Gavagnin et al. 1997;Sanvicente-Añorve et al. 2012;Zamora-Silva and Ortigosa 2012;Ortigosa and Simões 2019). Moreover, the most contrasting abundances found in this study were between Puerto Morelos and both, Arcas and Verde, yet PM and Verde were both sampled in the same months. ...
Three populations of the solar-powered sea slug Elysia crispata on reefs from the southern Gulf of Mexico and the Caribbean were analyzed. The aim was to describe and compare the changes in abundance and size of this species in different localities, as a function of depth and time-of-day. We hypothesized that differences in abundance would be related to locality, time of the day and depth, and differences in size would be related to locality and time of the day. Using snorkeling and SCUBA diving, all individuals within quadrats were counted and measured. A total of 680 organisms were recorded at Verde, Arcas and Puerto Morelos (PM) reefs at five times of the day (sunrise, morning, zenith, evening, and night) and depths of 0–13 m. Zero inflated negative binomial (ZINB) regressions adjusted to abundance data showed that E. crispata in Arcas and Verde reefs is expected to be more abundant (> 50) in shallow depths (< 2 m) at any time of the day except sunrise, whereas a low abundance (≤ 1 organism) is predicted in PM regardless of depth and time-of-day. According to linear models, size was not related to depth, but was related to locality and time-of-day, with sea slugs from Arcas and Verde having similar size, and both larger than those in PM. This information suggests that this sea slug is capable of moving within the reefs and helps to understand the unique biological phenomena of kleptoplasty.

Cryptic species in coral reefs, such as sea slugs, represent an important portion of their biodiversity, which is usually underestimated. Autonomous Reef Monitoring Structures (ARMS) have been implemented to estimate cryptic diversity in coral reefs. Therefore, this research aimed to contribute to the southern Gulf of Mexico (GM) and the Caribbean Sea (CAR) coral reefs’ sea slugs’ diversity and distribution using ARMS as a collection method. Fifty-eight ARMS were placed at three coral reefs in the GM and CAR, recovered after 1–2 years and then, disassembled at the laboratory. Plates were individually placed in trays with seawater, where we searched for sea slugs. A total of 242 organisms were found belonging to 31 species; 20 of them were identified to the species level, while 11 were determined up to genus or family. More than half of the species (19) were found in Bajo de 10 (GM), while 15 species were found in the CAR localities. Unlike previous studies, we assessed sea slugs’ diversity exclusively by an indirect sampling method. In this work, we found 9.4% of the sea slug diversity recorded in the Caribbean, and we report four determined species for the first time in the country. New records of species, and even one family for the GM stress the gap of information that we still need to fulfil in the area. We recognize ARMS as a useful tool to find juvenile, cryptic and rare species of sea slugs, as well as to standardize their quantification and record their diversity.
... Given that the LTRS is a natural protected area, no organisms were collected. Thus, most of the specimens observed were identified in the field through previous training based on patterns of coloration and of external morphological structures such as cerata, gill position, rhinophores, oral tentacles and surface of the notum, following the existing literature for the Gulf of Mexico and Caribbean (Carmona et al., 2011;Zamora-Silva & Ortigosa, 2012;Camacho-García et al., 2014;Caballer-Gutiérrez et al., 2015;Ortigosa et al., 2015;Goodheart et al., 2016). Likewise, specialized literature was used to distinguish complexes of species (Ornelas-Gatdula et al., 2012;Goodheart et al., 2015;Krug et al., 2016;2018;Valdés et al., 2017;Zamora-Silva & Malaquias 2017;Golestani et al., 2019;Bazzicalupo et al., 2020). ...
... They are common inhabitants of coral reefs, benthic algae, drifting sargassum, seagrass, rocks, and dead coral. Gastropods feed mainly on invertebrates (including other gastropods), small fish, and algae (Valdes et al., 2006;Sanvicente-Añorve et al., 2012a;Zamora-Silva & Ortigosa, 2012). Currently, there is much interest in the study of sea slugs, since they are important components of marine biodiversity (Crocetta et al., 2015). ...
... For the Bank of Campeche and Alacranes reef, there is a greater knowledge of the richness of species (Sanvicente-Añorve et al., 2012b;Ortigosa et al., 2013; with a current record of 94 species of sea slugs (Ortigosa & Simões, 2019). Two of three reef systems of Veracruz concentrate more investigations about sea slugs, being the Veracruz reef system (VRS) the best studied (Zamora-Silva & Ortigosa, 2012;Aguilar-Estrada et al., 2014;Cruz-López et al. 2015;Vital-Arriaga, 2016;Barrera-Correa, 2018;Olmos-García et al., 2019). For the Lobos-Tuxpan reef system, located at the north end of Veracruz state, there are few investigations that provide data about sea slugs species. ...
Background:
In the Lobos-Tuxpan Reef System Protected Natural Area (LTRS), Mexico, the presence of sea slugs has been documented in several scientific investigations, but the information is limited, scattered and out of date.
Goals:
To elaborate an updated list of species with new field data and the compilation of species previously reported in the literature for LTRS.
Methods:
Samplings were carried out in the Lobos reef (during November 2014 and 2017), Enmedio reef (September 2016, April 2017, June 2018, July and November 2019) and the Tuxpan reef (June and October 2016, and April 2017). The list of species was complemented with records of species previously reported for LTRS.
Results:
The updated list comprises up to 27 species of sea slugs. The most representative groups are: Order Cephalaspidea with nine species, Aplysiida with seven species and Superorder Sacoglossa with seven species. The distribution of Cyerce habanensis and Elysia cornigera extends to the north of Veracruz and Lobiger souverbii constitutes a new record for the Southwestern Gulf of Mexico Reef Corridor.
Conclusions:
Our study favorably increases the knowledge of sea slugs for the LTRS. This information could support strategies of conservation and protection for the management plans of this protect natural area.
... In the western Atlantic Ocean, research on this genus has focused mainly on taxonomy and isolated faunistic inventories (Ardila, Báez & Valdés, 2007;Zamora-Silva & Naranjo-García, 2008;Ortea et al., 2012;Zamora-Silva & Ortigosa, 2012;Camacho-García et al., 2014;Caballer-Gutierrez et al., 2015;Galvão-Filho et al., 2015;Goodheart et al., 2016), field guides (Valdés et al., 2006;García, Domínguez & Troncoso, 2008) and new distributional records (Padula et al., 2012;Malaquias, 2014;Ferreira et al., 2015;Ortigosa, Lemus-Santana & Simões, 2015). So far, the most in-depth work is a phylogenetic study of Elysia species from the Caribbean . ...
The western Atlantic Ocean is one of the areas with the largest species richness of sea slugs in the genus Elysia (30 out of the 101 species described have been reported in this region). Nevertheless, the lack of knowledge on many of these species hinders efforts to estimate regional richness and identify the factors affecting their distribution. We used the maximum entropy algorithm Maxent to develop ecological niche models for 14 species of Elysia in the western Atlantic Ocean. These models were meant to show the potential distribution of the genus and identify locations with the highest richness. Input data used to build niche models were presence records (obtained from several sources) and bioclimatic and geophysical variables from the Bio-ORACLE and MARSPEC platforms. Species with less than seven records were considered for the calculation of richness, but not for modelling. Results show low habitat suitability for the species modelled here at the mouth of rivers and in hypoxic zones and low-temperature areas. The two variables that best explained species distribution patterns were the distance to shore and the maximum monthly temperature. From the total area with adequate environmental conditions for the genus, only 20.3% is located within marine areas under some protection category.

Although several studies on the marine heterobranch gastropod fauna have been conducted in the Caribbean region, there is still a lack of knowledge on this group in Honduras. This study presents a checklist of "sea slug" species (Mollusca: Gastropoda: Heterobranchia) resulting from a series of samples taken at two very shallow areas in the Caribbean coast of Honduras, the Blanca Jeannette Kawas Fernández National Park and the Chachaguala Lagoon, located in the Cuyamel-Omoa National Park. A total of 194 specimens were collected and identified. They belong to 30 species, in 5 orders, 14 of which represent new records for Honduras. The present study increased the number of sea slugs known in the Caribbean coasts of Honduras to 93 species, and increased the degree of knowledge of marine heterobranchs of this region. Résumé : Diversité et distribution des limaces de mer (Mollusca : Gastropoda : Heterobranchia) dans deux sites de la côte caribéenne du Honduras. Bien que plusieurs études sur la faune de gastéropodes marins hétérobranches aient été menées dans la région des Caraïbes, il existe encore un grand déficit de connaissances pour ce groupe sur les côtes du Honduras. Cette étude présente une liste d'espèces de "limaces de mer" (Mollusca : Gastropoda : Heterobranchia), issue d'une série d'échantillonnages effectués dans deux zones très peu profondes de la côte caraïbe du Honduras, le Parc National Blanca Jeannette Kawas Fernández et la Lagune de Chachaguala, située dans le Parc National Cuyamel-Omoa. Au total, 194 spécimens ont été collectés et identifiés. Ils appartiennent à 30 espèces, comprenant 5 ordres, 14 d'entre elles représentant de nouveaux signalements pour le Honduras. Cette étude porte le nombre de "limaces de mer" connues le long des côtes caraïbes du Honduras à 93 espèces, et augmente le degré de connaissance de la faune hétérobranche marine de cette région.

Se actualiza el conocimiento de las babosas marinas de Veracruz a partir de registros fotográficos. Fundamentalmente se efectuaron muestreos con equipo de buceo libre para áreas someras y buceo autónomo para las pendientes profundas del Sistema Arrecifal Tuxpan (SAT) durante el periodo 2014-2016. Se identificaron un total de 11 especies de babosas marinas en el SAT de los cuales Navanax gemmatus y Oxynoe antillarum son nuevos registros para el Sistema Arrecifal Lobos-Tuxpan (SALT), mientras Chelinodura hirundinina, Aplysia morio y Flabellina engeli se registran por primera vez para el estado de Veracruz. Se amplía el ámbito de distribución para el Golfo de México de Thuridilla picta, Tyrinna evelinae, y dos individuo de la familia Phyllidiidae. Estos nuevos registros incrementan el inventario faunístico a 22 especies de babosas marinas para el SALT.
... The specimens found by Sanvicente-Añorve et al. (2012a, b) and those of the present study were all empty shells with the sole exception of one single live organism we collected alive. (Moore, 1958;García-Cubas, 1971;Ekdale, 1974;Vokes & Vokes, 1983;Valdés et al., 2006;Vicencio-de la Cruz & González-Gándara, 2006;Rosenberg et al., 2009;Sanvicente-Añorve et al., 2012a, b;Zamora-Silva & Ortigosa, 2012;Ortigosa et al., 2013;Redfern, 2013). ...

We report 37 species of heterobranch sea slugs from the National Park Alacranes reef, located in the Campeche Bank, at the southeastern Gulf of Mexico, of which 18 species are reported for the first time in this reef. With this contribution, the species richness in this national park increases to up to 67. The species Nakamigawaia felis, Petalifera sp., Elysia flava, Elysia pra-tensis and Bulbaeolidia sp. are reported in the Gulf of Mexico for the first time. The geographical distribution ranges for Oxynoe azuropunctata, Elysia ornata, Placida kingstoni, Aphelodoris antillensis and Tritonia hamnerorum are extended westward. Those for Elysia flava, Pleurobranchus areolatus and Felimare ruthae are extended both northward and westward.
... Se tiene conocimiento de 35 trabajos sobre moluscos para el PNSAV, de los cuales, aproximadamente una tercera parte se han realizado en Isla Verde, siendo los principales temas la generación y recopilación de inventarios faunísticos (Pérez, 1973;Castro et al., 1989;Quintana y Molina, 1991;Rosado y García, 1991;Pérez-Rodríguez, 1997; Zamora-Silva y Naranjo-García, 2008; Zamora-Silva y Ortigosa, 2012), ecología (Puig, 1983) y como indicadores de contaminación (Juárez, 2000;Dorantes, 2010), entre otros. ...

Es importante mencionar que, a pesar de que este estudio estuvo enfocado en la clase Gastropoda de la laguna arrecifal de Isla Verde, no se encuentran bien representados gasterópodos opistobranquios, los cuales han mostrado tener una riqueza importante en la zona (Zamora-Silva y Ortigosa, 2012). Este grupo de gasterópodos generalmente se encuentran crípticos, por lo que los estudios malacológicos que no están dirigidos a este tipo de organismos, como sucede también con los micromoluscos, generalmente reportan las especies grandes, como en el presente trabajo en el que se encontraron 3 de las 13 especies reportadas para el arrecife. ...
The community structure of the class Gastropoda in the reef lagoon of Isla Verde, Veracruz, was analyzed in 3 seasons: windy, dry and rainy. The community analysis of gastropods was based on 4 field trips conducted in October 2009, April, August and December 2010. The highest value of Shannon index was 2.422 bit/ind, the most abundant, 472 specimens, bottom was dead coral and the richest, 27 species, season was rainy season of 2010. The total number of records for this location was 111 species of gastropods. With the samplings carried out, the species richness increased 50%, finding a community with a total of 48 species, of which 18 were living representatives. The historical analysis was conducted based on a review of the area specimens deposited in national scientific collections, as well as records of species reported in the literature. Contrasting sampling with historical analysis, we observed a decrease locally critical in the number of species of large sizes and ornamental value, which reflects the urgency to realize and implement a management plan in the area.
