Nuevos registros y extensiones de distribución de mamíferos para guanajuato, méxico

Abstract: RESUMEN . La presente publicacion tiene dos objetivos principales: 1. dar a conocer varias especiesde mamiferos que son nuevos registros para Guanajuato y 2. mencionar localidades adicionales paraalgunas especies de mamiferos que han sido colectadas previamente en el estado, incrementando sudistribucion en la entidad. Los ejemplares se colectaron durante los anos 2003 a 2006 en variaslocalidades de la Reserva de la Biosfera “Sierra Gorda de Guanajuato” y se depositaron en la Coleccionde Mastozoologia de la Escuela Nacional de Ciencias Biologicas del Instituto Politecnico Nacional.Ademas de los colectados, se incluyeron otros animales que ya se encontraban en dicha coleccion. Sepresentan 11 nuevos registros y 14 especies que aumentan su distribucion conocida en Guanajuato,representados por 364 especimenes de 5 familias, 14 generos y 25 especies (20 roedores y 5murcielagos). De estas especies destacan tres roedores endemicos de Mexico ( Peromyscus difficilis, P.levipes y P. melanophrys ). De los murcielagos,

The emergence of vampire bat rabies in Uruguay within a historical context

Abstract: Pathogen spillover from wildlife to humans or domestic animals requires a series of conditions to align with space and time. Comparing these conditions between times and locations where spillover does and does not occur presents opportunities to understand the factors that shape spillover risk. Bovine rabies transmitted by vampire bats was first confirmed in 1911 and has since been detected across the distribution of vampire bats. However, Uruguay is an exception. Uruguay was free of bovine rabies until 2007, despite high-cattle densities, the presence of vampire bats and a strong surveillance system. To explore why Uruguay was free of bovine rabies until recently, we review the historic literature and reconstruct the conditions that would allow rabies invasion into Uruguay. We used available historical records on the abundance of livestock and wildlife, the vampire bat distribution and occurrence of rabies outbreaks, as well as environmental modifications, to propose four alternative hypotheses to explain rabies virus emergence and spillover: bat movement, viral invasion, surveillance failure and environmental changes. While future statistical modelling efforts will be required to disentangle these hypotheses, we here show how a detailed historical analysis can be used to generate testable predictions for the conditions leading to pathogen spillover.

Los mamíferos del Área Reservada para la Recreación y Educación Ecológica San Juan del Monte, Las Vigas de Ramírez, Veracruz, México

Abstract: The Recreation and Ecological Education Reserved Area San Juan del Monte is located in the municipality of Vigas de Ramirez, Veracruz, Mexico, and it is important due to its primary vegetation and it historically has been a key regarding the knowledge of mammals in the state of Veracruz; however, previous to this work there was no taxonomic list of its mastofauna. Field work was done between 2002-2005 and April, 2007 including direct and indirect methods and the review of specialized literature. Thirty six species grouped into 15 families and 7 orders are reported; 7 species are endemic to Mexico, 12 are shared with North and South America, 11 are only shared with North America and only 1 is shared with South America. Three species are listed in a Mexican risk category. Through fieldwork, records of 18 species were obtained and a highlight of 4 new records for the locality, literature refers to 31 species, 8 for which Las Vigas is the holotype locality. This mammal set of species equals 19% of mammal species for Veracruz and 31.5% just for the mountains of this state. The species richness of the San Juan del Monte area may be due to its geographical location on the Transmexican Volcanic Belt which has distinctive ecological and geographical features.

Sinopsis de los mamíferos silvestres del estado de Guanajuato, México, y comentarios sobre su conservación

Abstract: Introduction. Alfred Duges (1826-1910) began the formal study of wild mammals in the state of Guanajuato, Mexico. After his death the subject remained virtually forgotten for almost a hundred years. In the early years of the XXI century several authors began a period of revision of this state fauna based on recent field surveys, museum specimens and previously unnoticed literature. Objectives. The objectives of the present contribution were: to integrate a synopsis of the mammalian fauna of Guanajuato, documenting details for species and subspecies, recognizing proportions of its components at the family level; diagnose the current state coverage of records at the municipality level; outline general biogeographic affinities of the mammal fauna; develop a general conservation view with emphasis on endangered species and protected areas (but without losing sight of other species, spaces and policy instruments), and indicate pending aspects. Methodology. Results of previous literature reviews and museum specimen searches served to summarize mammal species richness, general state distribution and conservation status of taxa. Faunal affinities were outlined considering mammal species whose distribution is clearly associated with large physiographic-biogeographic regions converging in Guanajuato. Information on species at risk, protected areas, priority species, species management units and trade regulations, was gathered and collated to build an integrated conservation diagnostic. Lack of information on other conservation aspects was also addressed and main gaps were identified. Results. Ninety three species of 20 mammal families are known from Guanajuato, mainly Rodentia, Chiroptera and Carnivora. Records were found for 30 of 46 municipalities; but are still unrepresentative. Only 25 species have been recorded in more than five municipalities. The mammal fauna has affinity with the Mexican Plateau, with the slopes of the Gulf of Mexico and of the Pacific, and the Neovolcanic Belt. Most of the territory in Guanajuato is considerably disturbed; main conservation strongholds for species at risk are related to protected areas. Discussion and Conclusions. The 93 recorded species were catalogued with data on subspecies, general state distribution, and comments on taxonomy and conservation status. Guanajuato still needs systematic sampling; current records are not yet representative of the territory. This mammal fauna is a complex with different biogeographical components, which should guide any conservation strategy. Alteration of territory calls for effective conservation within protected natural areas (PNA), particularly for species at risk, but some PNAs do not have a validated mammal inventory. Management units (UMA) are scarce and aim at fostering a few species of economic interest; these units need to reorient their overall support for conservation of native biota. Some species are officially considered as priority ones, which can induce/enhance conservation in Guanajuato. Besides deepening the knowledge of species per se , several conservation aspects are pending, as examples: generate management plans for species at risk in PNAs and outside them, check the operation of UMA with emphasis on the subspecies of whitetail deer that have been introduced and managed, combat exotic and invasive species in the wild (this includes reducing extensive grazing), and characterize the social perception about conservation of mammals and their natural habitat.

Avistamientos recientes del águila real (Aquila chrysaetos) en la Reserva de la Biosfera Sierra Gorda de Guanajuato, México, y sus implicaciones en el plan de manejo de la reserva

Abstract: Documentamos por primera vez la presencia del aguila real ( Aquila chrysaetos ) dentro de la Reserva de la Biosfera Sierra Gorda de Guanajuato ( rbsgg ) en el estado de Guanajuato, Mexico. En mayo de 2015 observamos una pareja de aguila real cazando en la localidad de Mesita del Tigre, municipio de Victoria, Guanajuato. Nuestro registro tiene implicaciones en las politicas de uso de suelo contenidas en el Plan de Manejo de la rbsgg , donde sugerimos incluir medidas explicitas de proteccion del habitat de la especie y el establecimiento de programas de monitoreo en aquellas subzonas donde se ha registrado al aguila real o existe potencial para la anidacion de la especie.
