“…El estado de Yucatán ha sido aparentemente el más explorado; sin embargo, algunos sitios de la franja costera e inmediaciones fronterizas con Campeche y Quintana Roo no han sido estudiados. Esto concuerda con lo encontrado por Sosa-Escalante et al (2013) en su estudio sobre los mamíferos terrestres de la Península de Yucatán.…”

“…Éste es el caso para O. couesi, cuya subespecie O. couesi cozumelae está catalogada como amenazada, situación similar a lo que ocurre con P. leucopus cozumelae y R. gracilis insularis (SEMARNAT 2010). El ratón vespertino O. hatti también está considerado como amenazado ante la pérdida de su hábitat (Sosa-Escalante et al 2013) y R. spectabilis como un especie amenazada (SEMARNAT 2010) y por la IUCN como en peligro crítico (IUCN 2015). Es relevante mencionar que estas especies y subespecies, aún no cuentan con estudios que permitan conocer el estado actual de sus poblaciones silvestres.…”

“…Esta riqueza de especies ha estimulado la formación de numerosos científicos dedicados al estudio de los mamíferos terrestres en México, generando información numerosa y variada (Guevara-Chumacero et al 2001;Sosa-Escalante et al 2013). Como resultado, ha incrementado el número de especies registradas en el país que se debe no sólo a los nuevos descubrimientos, sino también al uso de nuevas técnicas de investigación que incluyen la genética y la ecología molecular (Vázquez-Domínguez et al 2009;Ramírez-Pulido et al 2014).…”

“…trampas cámara, detectores ultrasónicos, radio transmisores con rastreo satelital; O´Connell et al 2011;Díaz-Pulido y Payán 2012;Boonman et al 2013), han ayudado a comprender de mejor manera los cambios en la nomenclatura y las relaciones taxonómicas, patrones de distribución y uso de hábitat de especies elusivas. A escala regional, el número de especies registradas para cada entidad federativa cambia de manera frecuente, ya sea por la publicación de nuevos registro qs, o por cambios taxonómicos o de nomenclatura, lo que demuestra la importancia de actualizar periódicamente las compilaciones en existencia (Sosa-Escalante et al 2013).…”

“…En México, el Orden Rodentia está representado por ocho familias, que incluyen 233 especies de las cuales 180 corresponden a los pequeños roedores (Ramírez-Pulido et al 2014). Estos pequeños mamíferos resaltan como componentes clave en los procesos de sucesión y regeneración de las selvas tropicales, jugando un papel fundamental como agentes depredadores (DeMattia et al 2004) En la Península de Yucatán, provincia biogeográfica separada de las adyacentes por una flora y fauna particular en la que resaltan numerosas especies endémicas (Morrone et al 2002; Vázquez-Domínguez y Arita 2010), se distribuyen tres familias de pequeños roedores, Heteromyidae, Cricetidae y Muridae con un total de 15 especies, de las cuales ocho son endémicas de Mesoamérica (53.3 %) y una de México (6.6 %; Hernández-Betancourt et al 2010;Sosa-Escalante et al 2013). En esta península se han desarrollado estudios que han incrementado el conocimiento de las comunidades de pequeños roedores en diferentes puntos geográficos (Hernández-Betancourt et al 2010;Guzmán-Soriano et al 2013;Sosa-Escalante et al 2014;Vargas et al 2014).…”

Studies conducted on small mammals, such as tropical rodents, have generated great interest since they can easily provide information concerning to their populations. The present article presents an analysis of the bibliography and sampling locations of small rodents of the Yucatán Peninsula in Mexico. In addition, the information contained within the literature is revised in order to identify the geographic and thematic coverage of the species records for the purpose of analyzing perspectives in the study of small rodents and in order to contribute to the efforts being made towards their protection and conservation. Publications of periodical journals, books and book chapters published between 1901 and 2015 were reviewed and analyzed. The literature covered research of the 15 small rodent species that are distributed on the Yucatán Peninsula. The studies were grouped into 10 themes, an accumulation curve was prepared by decade for each state of the Yucatan Peninsula and a map of distribution was generated detailing the locations of the records of each species. A total of 212 references were obtained, of which 162 corresponded to articles in periodical publications and 50 to books and book chapters. The most studied species were Peromyscus yucatanicus, Heteromys gaumeri and Ototylomys phyllotis; in contrast, those for which practically no information exists were Tylomys nudicaudus, Reithrodontomys spectabilis and Heteromys desmarestianus. The State of Yucatán has been the most explored and has the greatest number of sites and records of small rodents, followed by Quintana Roo and finally Campeche. The most commonly addressed themes were distribution, taxonomy, phylogeny, diseases and parasitism. Gaps in the information were detected for the majority of the species in the different themes such as feeding, reproduction, anatomy and morphology. For this reason, it is important to carry out studies in these themes in order to further the knowledge of the small rodents of the Yucatán Peninsula. These studies could provide information with the aim to propose changes to their conservation status in both Mexican and international legislation, or take appropriate decisions regarding protection of their specific habitats.Los estudios realizados en pequeños mamíferos, como los roedores tropicales, han cobrado gran interés ya que proporcionan con cierta facilidad información acerca de sus poblaciones.

In Mexico, few studies have explored how environmental conditions in tropical dry forests (TDF) influence bat fly load even though, according to climate change scenarios, this ecosystem will experience a drier and warmer climate. Such an extension of the dry season in these ecosystems could have dramatic consequences for biodiversity, particularly in regions with plains where animals do not have elevational climate shifts. The present study therefore evaluates the effect of prevailing environmental conditions during 2015–2019, as well as host body conditions, on the infestation and abundance of bat-specific ectoparasites and the composition and bat fly load in the dry season of a TDF in Yucatan. Since Yucatan has an essentially flat and low-lying topography, organisms cannot escape from the predicted extreme conditions with elevational shifts. This region is therefore an excellent location for assessment of the potential effects of warming. We collected 270 bat flies from 12 species. Three streblid species (Nycterophilia parnelli Wenzel, Trichobius johnsonae Wenzel, and Trichobius sparsus Kessel) are new records for Yucatan. Our overview of the dry season bat ectoparasite loads reveals low values of richness and prevalence, but high aggregation. Our models detected significant differences in ectoparasite infestation and abundance over the years, but the environmental and body host condition variables were unrelated to these. We report that pregnant females are parasitized to a greater extent by bat flies during the dry season, which generally represents the season of most significant nutritional stress.

Survey on helminths of bats in the Yucatan Peninsula: infection levels, molecular information and host–parasite networks

Helminth species of Neotropical bats are poorly known. In Mexico, few studies have been conducted on helminths of bats, especially in regions such as the Yucatan Peninsula where Chiroptera is the mammalian order with the greatest number of species. In this study, we characterized morphologically and molecularly the helminth species of bats and explored their infection levels and parasite–host interactions in the Yucatan Peninsula, Mexico. One hundred and sixty-three bats (representing 21 species) were captured between 2017 and 2022 in 15 sites throughout the Yucatan Peninsula. Conventional morphological techniques and molecular tools were used with the 28S gene to identify the collected helminths. Host–parasite network analyses were carried out to explore interactions by focusing on the level of host species. Helminths were found in 44 (26.9%) bats of 12 species. Twenty helminth taxa were recorded (7 trematodes, 3 cestodes and 10 nematodes), including 4 new host records for the Americas. Prevalence and mean intensity of infection values ranged from 7.1 to 100% and from 1 to 56, respectively. Molecular analyses confirmed the identity of some helminths at species and genus levels; however, some sequences did not correspond to any of the species available on GenBank. The parasite–host network suggests that most of the helminths recorded in bats were host-specific. The highest helminth richness was found in insectivorous bats. This study increases our knowledge of helminths parasitizing Neotropical bats, adding new records and nucleotide sequences.
