“…Es importante destacar que Chaetomorpha linum es la especie más comúnmente registrada como epizoica, tanto en vertebrados como en invertebrados en distintos trabajos (Sentíes et al, 1999;Báez, 2002;Levenets, 2010;Martins et al, 2014), en regiones templadas y tropicales, cuya presencia puede deberse a su condición como especie oportunista (Sorce et al, 2018), misma que además puede ser indicadora de ambientes eutrofizados. En este trabajo, C. linum se registró en el muelle municipal que, de acuerdo con otros autores (Aguilar-Estrada et al, 2017;López et al, 2017), es un área contaminada y con altas tasas de sedimentación, por lo que la presencia de esta especie de alga verde podría ser un indicador de procesos de eutrofización.…”

Antecedentes y Objetivos: El conocimiento ficológico para la región del Pacífico mexicano es amplio, la mayoría de los estudios han estado orientados a conocer la flora adherida a sustratos rocosos. Sin embargo, es reducido el número de trabajos acerca de macroalgas que crecen sobre organismos vivos, como las algas epizoicas. El presente trabajo tiene como finalidad contribuir al conocimiento de la flora algal epizoica en el Pacífico tropical mexicano. Métodos: Se llevaron a cabo cuatro muestreos del molusco Chiton articulatus en dos localidades de Guerrero, México, durante 2014, para conocer las algas que crecen sobre él. Además, se realizó una revisión bibliográfica de estudios en el Pacífico tropical mexicano para obtener los registros de las algas que crecen sobre animales. Finalmente, se determinaron las algas en los moluscos mediante observaciones de talos completos y cortes. Resultados clave: En total se reportaron 124 especies, 81 géneros, 51 familias y 27 órdenes, distribuidos en cuatro divisiones de algas. Los órdenes con mayor riqueza específica fueron Ceramiales (23) y Corallinales (20) y las familias con mayor número de especies fueron Rhodomelaceae (13), Cladophoraceae (11) y Lithophyllaceae (10). Los géneros más diversos fueron Amphiroa y Cladophora (7). Se presentan, para Guerrero, 12 nuevos registros de especies, de los cuales tres son además nuevos registros para el Pacífico tropical mexicano y tres para el Pacífico de México. El estado con mayor número de especies registradas fue Guerrero (58). El sustrato más común fueron los moluscos. El grupo morfofuncional algal predominante fue los filamentos.Conclusiones: Los resultados de este trabajo demuestran que la biodiversidad de algas presente en los sustratos animales es alta, y contribuye notablemente a la riqueza específica registrada para Guerrero y para el Pacífico de México. Se hace patente la importancia de desarrollar más estudios que se enfoquen al conocimiento de la epibiosis algal.

“…Stomach contents were classified by taxonomic group, and each item was identified to the lowest possible taxonomic level. A stereoscopic Stemi 2000-C microscope (Zeiss, Oberkochen, Germany) and specialized literature were used to identify prey of the following groups: echinoderms (Hendrickx 1995a, Solís-Marín et al 2005, Hernández-Herrejón et al 2008, gastropods (Baqueiro et al 1982, Poutiers 1995b, Hendrickx et al 2014, Aguilar-Estrada et al 2017), bivalves (Holguín-Quiñones and González-Pedraza 1994, Poutiers 1995a), malacostracans (Hendrickx 1995b(Hendrickx , 1995cSalgado-Barragán and Hendrickx 2010), and other invertebrates such as annelids, poriferans, and isopods (Brusca 1980, Morris et al 1980. All taxonomic names were verified using the World Register of Marine Species (WoRMS).…”

The Pacific Porgy (Calamus brachysomus) is a commercially important fish in Baja California Sur, Mexico, where it reproduces year-round. The feeding habits of fishes can change during reproductive stages in response to changes in energetic demand. The objective of this study was to characterize the trophic habits of the Pacific Porgy and how these varied by sex, reproductive stage, and season. Monthly samples were obtained from July 2015 to July 2016 in the central Gulf of California. The stomach contents of 235 specimens (108 males and 127 females) were analyzed. The trophic spectrum comprised 90 prey items, including 58 mollusks, 14 echinoderms, 13 arthropods, 2 chordates, 1 annelid, 1 poriferan, and algal remains. According to the prey-specific index of relative importance (%PSIRI), the most important prey items were the bivalves Transennella spp. (7.24%), Argopecten spp. (6.94%), Anadara spp. (6.25%), Septifer zeteki (6.19%), and Tivela spp. (6.1%). The trophic spectrum varied significantly by season but not by sex or reproductive stage. There were no significant interactions between sex and season or sex and reproductive stage. According to the Levin index, C. brachysomus exhibited a narrow trophic niche (Bi = 0.31). Costello graphs indicated the dominance of a few species, with shifts in the relative abundance of prey species. Based on the trophic analysis, C. brachysomus was classified as a tertiary consumer (3.18). Therefore, C. brachysomus represents an important link between upper and lower trophic levels. Based on these results, we inferred that the Pacific Porgy is an opportunistic predator that feeds actively during all reproductive stages. Thus, the energetic requirements needed for reproduction appear to be covered by the prey that comprise the trophic spectrum of C. brachysomus without this species needing to switch to more energy-rich prey.

“…Recently, this has changed a bit and more ecological studies have been published (Corado-Nava et al, 2014;López et al, 2017). Studies including the interactions among both communities are still scarce; one being the research of Aguilar-Estrada et al (2017), who documented the mollusks associated with the macroalgae assemblages in the rocky intertidal from Ixtapa-Zihuatanejo, Guerrero. Given the importance of mollusks as a structuring component of the rocky intertidal communities and the scarce information available about their association with algae, this study aims to describe the composition and coverage of the epibiotic algae associated with Chiton articulatus.…”

Algal epibiont species on Chiton articulatus (Mollusca: Polyplacophora) from a rocky intertidal coast from the Mexican Tropical Pacific

Chiton articulatus, a mollusk endemic to the Mexican Pacific, is a species whose ecological associations with the algae that colonize it are not well known. This work describes the epibionts observed on the shells of this species. We collected chitons in the rocky intertidal of 2 localities in the state of Guerrero, Mexico. Sixty-two chitons were collected that had 50 species of algae. The best represented family was Cladophoraceae with 10 species. Of the total number of specimens, 26 had epibionts whose distribution on the shell was different: 11 species on the valves, 17 on the suture, 1 on the belt, and 22 species shared in the first 2 zones. Five morphofunctional groups of algae were recognized: microscopic, filamentous, crustose, foliose and corticated filaments, with a predominance of filaments. A relationship was found between the size of the chitons and the percentage of algal cover. Studies like the present one are important due to the interaction between both organisms, since chitons offer surfaces of easy colonization for algae. Furthermore, records of species that do not commonly appear in floristic inventories can be found on these.
