Based on a normative vision of ecotourism, these indicators (i) assess the natural conditions that determine the potential long-term conservation of this species, and (ii) provide indices for evaluating the social and professional potential of the populations that reside near fragments of the rainforest for developing ecotourism services capable of generating socially-balanced economic benefits. Based on fragments of rainforest with extant troops of A. palliata in the northern Isthmus of Tehuantepec, we demonstrate the applicability of the indices in decision-making founded upon transparent, multivariable criteria related to assigning economic and human resources to foment ecotourism in specific regions.

This paper confirms the presence of Gerrhonotus infernalis for the state, expanding the range of the distribution known for the northeast of the state based on three records from the Sierra Gorda.

In August 2009 in the state of Hidalgo, we caught one Sturnira ludovici and one Artibeus lituratus (both females) exhibiting leucism. In addition, one leucistic Macrotus waterhousii was caught in April 2010 in Guerrero. Leucism has been infrequently reported and may be more common than suggested by published results. In order to evaluate this supposition, we checked the mammals collection of Escuela Nacional de Ciencias Biologicas (Instituto Politecnico Nacional) to look for other evidences of leucism in bats. We found six more specimens, three Artibeus jamaicensis and three Tadarida brasiliensis (collected in different years in the states of Aguascalientes, Hidalgo, and Puebla) that manifested leucism. These specim...

These records are within western versant of the Sierra Gorda at Sierra Gorda de Guanajuato. Evidence is given that supports the idea that the area supports a herpetofaunal assemblage of tropical affinities.<br>Se presentan 5 nuevos registros de reptiles para el estado de Guanajuato; Lampropeltis triangulum dixoni, Leptodeira annulata cusiliris, Oxybelis aeneus, Tropidodipsas sartorii y Scincella silvicola caudaequinae. Todos localizados en la vertiente oeste de la sierra Madre Oriental, en la sierra Gorda de Guanajuato. Se proporciona evidencia de un ensamble herpetofaunístico de afinidad tropical a subtropical presente en la región.

La presencia de ambas especies en el desierto sin duda es clave para mantener la dinámica del ecosistema en equilibrio, sin embargo los estudios realizados previamente en esta localidad se han enfocado principalmente en los pequeños mamíferos herbívoros (roedores, lagomorfos y venados) y escasamente sobre estos depredadores. El presente estudio tiene como objetivo principal determinar algunas de las principales características sobre la ecología de gatos monteses y coyotes relacionadas con su papel como depredadores y su relación con sus principales presas (interacciones depredador-presa) que permitirán implementar un plan de monitoreo de ambas especies en la Reserva de la Biosfera de Mapimi, con las que podrá conocerse parte de la dinámica del ecosistema desértico que habitan....

Molecular work based on mitochondrial and nuclear markers proposed the existence of four haplogroups within P. melanophrys. Peromyscus mekisturus (Puebla deer mouse) was included in one of these haplogroups. We tested the consistency between this hypothesis and external morphology, quantitative and qualitative cranial attributes, and ecological data for a sample of 1,155 specimens spanning the species distribution. We found ecological and morphological consistency with the phylogenetic pattern for P. melanophrys but not for P. mekisturus. We reassessed the taxonomic and nomenclatural status of the populations and type specimens formerly included in P. melanophrys. We concluded that these populations constitute four species: P. zamorae (Zamora deer mouse), distributed in the Mexican Plateau at elevations > 1,500 m; P. micropus (small-footed deer mouse), from lowland tropical de...

They are repositories of germplasm and data on modified or extinct natural populations, providing valuable information for understanding anthropogenic impacts on the natural world. We appraised the scientific value of the three mammal collections maintained by the Instituto Politécnico Nacional of Mexico (IPN): Escuela Nacional de Ciencias Biológicas (ENCB), CIIDIR Durango (CRD), and CIIDIR Oaxaca (OAXMA). We evaluated their specimen inventory, geographic coverage, and scientific importance for mammalogy. We assessed their physical conditions and provided insights into their future as data sources for understanding natural changes in the 21st century. We measured the scientific importance of the collections in terms of the number of specimens and taxa held and their geographic coverage. We also quantified research projects, publications, theses, and dissertations that have used at least one specimen, associated...

In order to describe the bat community of San Luis de la Paz, México, abundance, size and trophic guild of the specimens were associated with their habitat, and diversity, equitativity, species richness, and dominancy were estimated. The highest diversity was shown in succulent-roset desert shrub. The most frequent family was Phyllostomidae and the most abundant species was Sturnira lilium. Insectivorous bats constituted the most diverse guild. High species richness shown by this community may be due to its location in the transition zone between the Nearctic and Neotropical regions, to the presence of endemic species, and to its diversity of habitats and food resources.
