This chapter reports recent malacological research on Chetumal Bay, and particularly on the data from Oxtankah, Quintana Roo. The author collected species present in Chetumal Bay and compared these with archaeological collections from a series of excavations around Oxtankah. He notes that relatively few species are found in the muddy bay bottom itself and, while these were exploited for food, most of the broad range of species identified from archaeological remains stemmed from the Caribbean. A few Pacific species, obvious imports at Oxtankah, are also represented in the collections. Technological use wear studies of tool scars on worked shell objects and replication analysis of worked shells documents shell manufacturing techniques used at the site.

AbstractMillipede diversity in tropical regions, and in Mexico in particular, is still mostly unknown. A modest but recurrent source of new Mexican species is the colonization of exotic species, due to human activity. The invasive speciesCylindrodesmus hirsutusPocock, 1889 has spread from its area of origin in Indonesia or Melanesia and become a virtually pantropical species. Although long known from South and Central America, reports from the Caribbean are sparse and limited to some eastern islands and southern Central America. On 9 March 2016, two adult specimens were found on Cozumel Island, Quintana Roo, in an area of medium semideciduous tropical forest. This paper comprises the first record of this species from Mexico and the northern Caribbean. Given the intense commercial activity in the region, the presence of more populations both in Cozumel Island and in the mainland coast is highly probable.

Additional larval, juvenile, and adult specimens and live photographs of the Caribbean Kuna Goby, Coryphopterus kuna, expand the known geographic range for the species and allow a comprehensive description of all the life stages for this recently-discovered species, including age and growth estimates from daily otolith increments. The Kuna Goby is found widely throughout the tropical western Atlantic, including southern Florida, Quintana Roo on the Yucatan Peninsula of Mexico, Belize, Honduras, Panama, San Andres Island, Bonaire, and Guadeloupe. The additional specimens indicate that C. kuna has a pelvic frenum and that females have a black flag on the outer portion of the first two spinous dorsal-fin membranes, while males have a dark stripe along the mid-length of the spinous dorsal fin. The development of melanophores on pelagic larvae through the transition to settled juvenile is described. The Kuna Goby is a notably small goby: larvae settle around 7–9 mm SL, adults mature at 10–11 mm SL and then only attain about 17 mm SL. Kuna Gobies settle after a 60-day pelagic larval life, and mature rapidly. They are reproductive in as few as three weeks and live for about two months after settlement. This is the first reported fish in which the pelagic larval duration is generally longer than the post-settlement lifespan.

Pesquisadores demonstraram que o vírus SARS-CoV-2, responsável pela pandemia da COVID-19, apresenta membrana lipídica (gordura) em sua estrutura, e o uso do sabão durante a lavagem das mãos é uma das medidas mais eficazes para eliminá-lo, embora muitas localidades não têm acesso à água potável nem, tampouco, ao uso de sabão para higienização. Assim, com o apoio do Programa Hidrológico Intergovernamental para América Latina e Caribe, o Núcleo da Cátedra UNESCO: Água, Mulheres e Desenvolvimento (NuCat) desenvolveu um curso de extensão virtual com o objetivo de disseminar a metodologia de fabricação de sabão, que utiliza óleo de cozinha residual. O curso incluiu três módulos: 1) a importância do sabão e da higiene como auxílio no combate à COVID-19; 2) a educação ambiental como forma de proteção aos recursos hídricos; e 3) introdução aos princípios de empreendedorismo e cooperativismo aplicados à produção de sabão. Entre 18/05/2020 a 23/06/2020, videoaulas sobre o tema foram disponibilizadas no canal do Youtube: “Projeto Recursos Hídricos e Sabão Artesanal”, o qual alcançou mais de 360 inscritos naquele período. Uma sala virtual via plataforma de educação a distância Moodle também foi disponibilizada para os participantes que se interessassem em adquirir certificado. Os resultados mostraram, ao final do curso, mais de 4.400 visualizações no canal do Youtube e 80 participantes certificados. Os participantes deixaram feedback positivo, com 95% deles declarando-se satisfeitos ou muito satisfeitos com o curso. Palavras-chave: Meio Ambiente; Saneamento; Empreendedor; Ensino a distância Artisan Soap and Entrepreneurship: Virtual socio-educational actions for the protection of Water Resources and combating the COVID-19 pandemic Abstract: Researchers have demonstrated that the new SARS-COV-2 virus, responsible for the COVID-19 pandemic, has fats in its composition, making it so that washing hands with soap is one of the most effective measures for its elimination. However, many places do not have access to potable water or soap. Therefore, with the support of the Intergovernmental Hydrological Program for Latin America and the Caribbean, the UNESCO Chair Core: Water, Women, and Development (NuCat) developed a virtual extension workshop aiming at disseminating used-oil-based soap manufacturing techniques. This workshop comprises three modules: 1) the importance of soap and hygiene to fight the COVID-19; 2) environmental education as a way of protecting water resources, and 3) an introduction to the principles of entrepreneurship and cooperativism applied to soap production. Between 18/5/2020 and 23/6/2020, video classes on the topic were made available on a Youtube channel created for this purpose. The channel “Projeto Recursos Hídricos e Sabão Artesanal” reached over 360 subscribers during this period. A virtual room via the Moodle education platform was also made available to participants interested in a certificate. At the end of the workshop, the YouTube channel reached over 4,400 views, and 80 participants were certified. The participants left extremely positive feedback, with 95% of them declaring themselves satisfied or very satisfied with the course.

AbstractOne short-snouted spinner dolphin Stenella clymene individual stranded on the coast of Quintana Roo, Mexico, was examined for stomach and lung nematodes. During necropsy, a large number of nematodes of the species Skrjabinalius guevarai were found in the airways. Additionally, some larval Anisakis sp. were found in the stomach. Both nematode species are reported for the first time from this host. The present is the first helminthological study of the short-snouted spinner dolphin in Mexico and adjacent waters of the Caribbean Sea. S. guevarai is reported for the first time from the western Atlantic Ocean.

Diabetes is a serious public health problem in Mexico with a particular concern in Isla Mujeres. With its sparkling beaches, delicious ceviche, and dazzling sunsets, the Caribbean island of Isla Mujeres in Quintana Roo, Mexico, is paradise to all; nevertheless, an estimated 80 percent of the population has Type 2 diabetes. In a primarily isleño (islander) population, I conducted a mixed method ethnographic study that integrated an anthropological lens with an applied research design. The rate of Type 2 diabetes within this population highlights the need to include in-depth, qualitative exploration of local context, social environment, and isleño culture when considering how to create change. Clinical data, formal and informal interviews, and surveys reveal the need to improve accessible patient education programs. The focus of this ethnography study is to understand the cultural and societal domains of food as a social practice, nutrition, and education that have led to this food-related disease.

Testudines is the crown-group that includes all living forms of turtles and their closest relatives. This group is known from the late Triassic and persists to this day. The fossil record of Testudines in Mexico is scarce and has been previously compiled in several papers. Here we present an update including all osteological and ichnological records from México and Central America. In Mexico, the Testudines fossil record extends from the Late Triassic to the Pleistocene, being widely abundant during the Pleistocene. Kinosternon and Gopherus are the best represented taxa, known from the late Miocene (Hemphillian) to the late Pleistocene (Rancholabrean). Fossil turtles are well represented in Mexico, excluding the states of Campeche, Mexico City, Colima, Guerrero, Queretaro, Quintana Roo and Sinaloa. On the contrary, the ichnological records are only known in Coahuila, Puebla and Zacatecas. In Central America there are records of fossil turtles in El Salvador, Honduras, Costa Rica and Panama, the latter being the country holding most records. Finally, nine new species have been described in the region, six for Mexico (Notoemys tlaxiacoensis, Yelmochelys rosarioae, Mexichelys coahuilaensis, Gopherus donlaloi, G. auffenbergi and G. pargensis, of which G. auffenbergi is synonymous with G. berlandieri and G. pargensis is considered a nomen vanum) and three in Central America (Rhinoclemmys nicoyama from Costa Rica, and Rhinoclemmys panamaensis and Staurotypus moschus from Panama).

Chikungunya virus (CHIKV) is an alphavirus transmitted by Aedes mosquitoes, which causes Chikungunya fever. Three CHIKV genotypes have been identified: West African, East-Central-South African and Asian. In 2014, CHIKV was detected for the first time in Mexico, accumulating 13,569 confirmed cases in the following three years. Studies on the molecular diversification of CHIKV in Mexico focused on limited geographic regions or investigated only one structural gene of the virus. To describe the dynamics of this outbreak, we analyzed 309 serum samples from CHIKV acute clinical cases from 15 Mexican states. Partial NSP3, E1, and E2 genes were sequenced, mutations were identified, and their genetic variability was estimated. The evolutionary relationship with CHIKV sequences sampled globally were analyzed. Our sequences grouped with the Asian genotype within the Caribbean lineage, suggesting that the Asian was the only circulating genotype during the outbreak. Three non-synonymous mutations (E2 S248F and NSP3 A437T and L451F) were present in our sequences, which were also identified in sequences of the Caribbean lineage and in one Philippine sequence. Based on the phylogeographic analysis, the viral spread was reconstructed, suggesting that after the introduction through the Mexican southern border (Chiapas), CHIKV dispersed to neighboring states before reaching the center and north of the country through the Pacific Ocean states and Quintana Roo. This is the first viral phylogeographic reconstruction in Mexico characterizing the CHIKV outbreak across the country.
