Los especialistas en mamíferos (mastozoólogos) frecuentemente señalan que Oaxaca es el estado con mayor diversidad de mamíferos en México, esto se debe, principalmente, a que Oaxaca está ubicado entre la región neotropical y neártica, y a la heterogeneidad ambiental, lo que promueve la presencia de diferentes tipos de vegetación y múltiples hábitat...
Biodiversity is multidimensional and should therefore be characterized using multiple approaches to understand the patterns at various temporal and spatial scales. Taxonomic, functional, and phylogenetic measurements of diversity are now recognized as comprehensive methods for understanding the relationships among species diversity, associated ecol...
Protected sites managed by indigenous people have been used for decades to conserve natural resources. These sites can be considered “conservation islands” and can maintain high biodiversity. This study explores the diversity and structure of medium and large mammals in (1) four protected natural areas in Oaxaca, Mexico, and (2) two different conse...
Urbanization is one of the leading causes of habitat loss, which has increased significantly in tropical regions in recent years, leading to the loss of species, their ecological functions, and evolutionary history. To determine the effect of urbanization on the diversity of bat communities in urban and suburban environments, we analyzed the ↵ and...
En los últimos años, los mamíferos se han visto gravemente afectados por la pérdida de hábitat, la cacería furtiva, las especies invasoras y el cambio climático. Estos vertebrados tienen una variedad de roles funcionales que impactan en el funcionamiento de los ecosistemas. Para evaluar esta diversidad funcional, es necesario contar con una lista d...
El estudio de la biodiversidad va más allá de contar cuántas especies habitan un área. Sin embargo, esta medida ha sido la más utilizada en estudios ecológicos. No obstante, la diversidad filogenética (medida del parentesco evolutivo de las especies) y la diversidad funcional (variedad de funciones de las especies) ofrecen otras perspectivas que ti...
Todos los seres vivos que viven en un ecosistema desempeñan roles funcionales y realizan un trabajo en equipo, de ello depende su existencia y la de su hábitat.
Southern Mexico’s tropical forests are home to the country’s highest richness of mammal species; La Chinantla region is situated within this area, its name from the indigenous group residing in the area and holding territorial ownership, namely the Chinantecos. In La Chinantla, there are no Protected Areas; instead, there are Areas Destined Volunta...
Predator species are essential for ecosystems as they maintain the ecological integrity of the habitat. Particularly, felids populations have declined globally due to their sensitivity to habitat disturbances. Nevertheless, in Mexico, there are areas protected by indigenous communities to preserve a portion of their territory, benefiting multiple s...
Skunks are important for the ecosystems as consumers of fruits, seeds, and insects. The hooded skunk (Mephitis macroura) is a medium-sized mammal common in North America, but its abundance is poorly known throughout its range. In a semiarid location in southern Mexico, we deployed a camera traps array to study the populations of meso-carnivores in...
Sabemos que los ratones tienen hábitos terrestres o arborícolas, que comen hierbas o semillas, pero que naden y se alimenten de peces e insectos acuáticos sí que es increíble de imaginar, pero existen y viven en México.
Estimating density and activity patterns is useful for management and conservation of species. Data for Mexican bobcat (Lynx rufus) populations are scarce. Here we estimated the density of a bobcat population in Oaxaca, southern Mexico, and evaluated its daily activity patterns. We also evaluated macroecological patterns of bobcat density across it...

En este trabajo se analizaron las tendencias mundiales en las ev...
Estamos acostumbrados a ver personajes de ratones en televisión, pero cuando escuchamos la palabra ratón o vemos alguno en nuestra casa, solo queremos huir. ¡¡¡Sin embargo, los ratones son animales increíbles!!!
Wildlife crime, including illegal harvesting, poaching, use, and trade, is a global issue. While studies on wildlife crimes have been performed on a global scale, it is also essential to assess their impact on native species at national scales. Investigating illegal activities involves analyzing law enforcement and seizure data, especially in areas...
Biological collections have become a key tool for biodiversity research. 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 Po...
Interest in the study of mycotic diseases in bats has increased after the identification of bats affected by white-nose syndrome in the northern United States.

Abstract
Bat acoustic libraries are important tools that assemble echolocation calls to allow the comparison and discrimination to confirm species identifications. The Sonozotz project represents the first nation-wide library of bat echolocation calls for a megadiverse country. It was assembled following a standardized recording protocol that aimed...
Understanding the mechanisms that drive the assembly of communities is a central goal in ecology, and phylogenetic approaches allows for the testing of hypotheses related to such mechanisms. We analyzed assembly mechanisms of cricetid rodents in an environmentally heterogeneous region of southern Mexico by assessing their phylogenetic diversity and...
Bat communities' responses to land use change in neotropical montane forests have scarcely been studied. We hypothesized that, like in lowland forests, a montane agricultural area will have a lower species richness, abundance, diversity and species composition of understory phyllostomid bats than a native forest (montane cloud forest and pine-oak f...
Biodiversity is multidimensional and different mechanisms can influence different dimensions. The spatial distribution of these dimensions can help in conservation decisions through the location of complementary areas with high diversity. We analyzed congruence in spatial patterns of species richness and functional diversity of cricetid rodents in...

The tapir plays an important role in its ecosystem as an herbivore and effective seed disperser, as well as being of cultural importance. However, the ecology and ethnozoology of the endangered Baird´s tapir in the north of Oaxaca, Mexico is poorly understood. We used camera-traps to estimate its relative abundance and density and describe the acti...
Barn Owls have a flexible diet for catching their prey based on availability. However, little has been explored about the age class distribution of their main prey. In this work we analyzed the prey diversity, niche width and age class frequency of their main prey from pellets of Barn Owls (Tyto alba) found in a cave surrounded by oak forest in Cen...
The loss and degradation of forests in tropical regions have modified tree cover, creating deforested landscapes. It has been suggested that there are thresholds in these landscapes beyond which the diversity, distribution, abundance, and fitness of different biological groups can be affected. In this study, the ecological habitat thresholds were d...
