Bats are abundant and effective seed dispersers inside the forest, but what happens when a forest is fragmented and transformed into pasture? The landscape at Los Tuxtlas, Mexico, originally rainforest, is greatly fragmented and covered with pastures. We analyzed the seed rains produced by frugivorous bats and birds under isolated trees in pastures...

El objetivo de esta revisión es responder a dos preguntas básicas: (1) ¿contribuyen los murciélaigos frugívoros neotropicales como agentes dispersores de semillas, a la regeneración de selvas? y (2) ¿cuáles podrían ser las consecuencias ecológicas si los murciélagos frugívoros desaparecieran de los potreros del Trópico húmedo? Se revisó la infoimac...

La transformación de las selvas tropicales en pastizales ýreas de cultivo frecuentemente conduce a la pérdida de especies locales. Sin embargo, falta información sobre el papel de algunos elementos aislados del paisaje fragmentado en el mantenimiento de la biodiversidad. Este estudio registró la presencia de murciélagos frugívoros durante todo el a...

Emerging infectious diseases (EIDs) of zoonotic origin appear, affect a population and can spread rapidly. At the beginning of 2020 the World Health Organization pronounced an emergency public health advisory because of the SARS-CoV-2 coronavirus outbreak, and declared that Covid-19 had reached the level of a pandemic, rapidly spreading around the...

Infundadamente se han mencionado a los murciélagos como los portadores del SARS-CoV-2 y como los causantes de la actual pandemia COVID-19, sin embargo, ellos nos proporcionan grandes beneficios y servicios como depredadores de insectos transmisores de enfermedades y plagas de nuestros cultivos, como polinizadores y dispersores de semillas, entre ot...

Chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), has been related to rapid population declines and extinction in amphibians around the world. Bd has been associated with a severe decline in amphibian populations in southern Mexico. We compare the prevalence and intensity of Bd infection in two tree frogs in southern Mexic...

In this study, we document the prevalence and intensity of Batrachochytrium dendrobatidis infection in a population of the Chimalapas Toad (I. tutelarius) in southern Mexico.

Seguramente en algún momento te has preguntado: ¿por qué existen estos fastidiosos mosquitos y las cochinas cuca rachas?, ¿de qué sirven las ratas?, ¿para qué hay murciéla gos? La respuesta es muy simple: es porque hay alimento disponible y estos animales lo aprovechan. Si no hay qué comer… desaparecen. Aquí hablaremos de los murciélagos, los único...

La pérdida de los bosques tropicales del mundo es una de las principales amenazas para la biodiversidad a nivel global, ya que al menos dos tercios de las especies terrestres habitan en los trópicos. La fragmentación del bosque trae como resultado la creación de “islas” de la vegetación original (remanentes), rodeadas de una matriz, generalmente de...

Animal crowding from different regions in live animal markets can cause zoonosis. Caged animals promotes interactions and pathogen transmission among different taxa. These interactions among different taxa never would occur in natural conditions. Laws to protect wildlife should be firm and clear, with international regulations and sanctions for cou...

Las zoonosis, como la rabia, el paludismo o el dengue, han afectado a los humanos desde nuestro origen. Ante la COVID-19, nuestro objetivo es destacar que los murciélagos no son los culpables de la pandemia; por el contrario, son muchos los servicios que proporcionan al ser humano en la salud, la agricultura, la alimentación y la economía.

Los murciélagos han sido culpado injustamente como los responsables de la pandemia del Covid-19. En realidad aportan enormes beneficios a nuestro planeta. A excepción de algunas aves, como búhos y lechuzas, los murciélagos son los únicos vertebrados voladores nocturnos, lo cual les permite aprovechar recursos como flores, frutos, insectos y pequeño...

Diariamente estamos en contacto directo con algo donde los murciélagos participan y nos benefician. Por mencionar algunos ejemplos, si usas ropa de algodón, si desayunaste cualquier cosa que tenga maíz, tomate, chile, azúcar, si tu comida la acompañas con arroz, calabaza, pepi-nos, un mezcal o un tequila y de postre un chicoza-pote, y cenas un tama...

Although cases of independent adaptation to the same dietary niche have been documented in mammalian ecology, the molecular correlates of such shifts are seldom known. Here we used genome‐wide analyses of molecular evolution to examine two lineages of bats that, from an insectivorous ancestor, have both independently evolved obligate frugivory: the...

A large part of the natural vegetation in the tropics has been replaced by pastures and crop fields. To evaluate the value of mango orchards in the conservation of phyllostomid bats in a fragmented, heterogeneous landscape in Veracruz, Mexico we compared species richness, total abundance, dominance, evenness and abundance per feeding guild of bats...

Chytridiomycosis caused by fungus Batrachochytrium dendrobatidis (Bd) is one of the decline global causes of amphibians. Currently, it is distributed throughout a broad range of climates and ecosystems around the world. An epidemic wave of chytridiomycosis began in North America, resulting in population decline and local extinction of many species,...

In Mexico, the Long-tailed Wood-Partridge (Dendrortyx macroura) is distributed in the mountains of the Trans-Mexican Volcanic Belt, Sierra Madre del Sur and Sierra Norte de Oaxaca; while the Bearded Wood-Partridge (D. barbatus) is distributed in the Sierra Madre Oriental (SMO). There is a controversial overlap in distribution (sympatry) between the...

For birds, we tested the efficacy of a technique used to obtain faecal samples and their seed content from bats by placing plastic sheets below mist nets. This method was compared with that of collecting faecal samples using cotton bags. Plastic sheets were placed below each of eight mist nets to obtain faecal samples from birds caught in cloud for...

Morphometric variation and leaf symmetry was characterized in a population of Platanus mexicana along a riparian altitudinal gradient in Veracruz. A total of eight morphometric characters were evaluated in 1,800 leaves from 15 trees per site, collected at 70, 200, 600 and 1,700 m. Morphometric differences among sites (F (24, 5189) = 21.1, P < 0.05)...

Species can co-exist within a community when their use of limiting resources is differentiated. To test whether differentiation facilitates coexistence, we quantified differences and overlap in habitat use, fruit consumption, morphological characteristics, and the relationship with vegetation structure for two pairs of ecologically similar frugivor...

Forest conversion to anthropogenic uses is a generalized phenomenon throughout tropical Latin America. We evaluated whether patches of secondary forest, which develop relatively rapidly after field abandonment, contribute to conservation of phyllostomid bat assemblages. Our objective was to compare patterns of phyllostomid bat abundance and the str...

It has become clear that native species are incorporated na- turally under the canopy of many tree plantations. This process of incorporation (facilitation) can be used as an opportunity to create successional models in restoration and species reintro- duction projects. The need to incorporate basic ecological in- formation is a critical issue in t...

The current distribution of the endemic Perote ground squirrel (Xerospermophilus perotensis) and its future potential response to climate change have not been addressed. Thus, in this work, we focus on both aspects of this species by means of ecological niche modeling, using different general circulation models and Intergovernmental Panel on Climat...

Most studies on frugivorous bat assemblages in secondary forests have concentrated on differences among successional stages, and have disregarded the effect of forest management. Secondary forest management practices alter the vegetation structure and fruit availability, important factors associated with differences in frugivorous bat assemblage st...

Recently it was proposed that Centurio senex specializes on hard fruit because of its strong bite compared to other similar-sized frugivorous bats; however, this hypothesis has not been tested. We tested the hardness of 5 fruit species eaten by bats, including Sideroxylon capiri (Sapotaceae), here reported for the 1st time as part of the diet of C....

Species-specific traits of trees affect ecosystem dynamics, defining forest structure and understorey development. Ochroma pyramidale is a fast-growing tree species, with life-history traits that include low wood density, short-lived large leaves and a narrow open thin crown. We evaluated forest succession in O. pyramidale-dominated secondary fores...

We studied Phyllostomidae bat assemblage structure in patches of secondary forest dominated by the pioneer tree Ochroma pyramidale, largely (>85%) or partially (<35%) surrounded by a matrix of tropical rain forest, to test 3 hypotheses: the highest bat diversity and richness is observed in the matrix rain forest in comparison to secondary forest pa...

Seed dispersal is a key process for plant colonization and for the establishment of many plant populations in tropical environments. A large proportion of all tropical woody plants with fruits and seeds depend on frugivorous vertebrates for their dispersal, and frugivorous bats are essential for the dispersal of seeds from many tropical plants. Man...

Frugivorous bats respond differently to changes in the landscape, depending on their morphological and ecological characteristics, so only some species cross deforested areas and disperse seeds in these environments. In this study we analyzed the plant species dispersed by bats in tropical rain forest and patches of secondary vegetation of a forest...

Abies religiosa (Pinaceae) is native to mountains of central and southern Mexico and western Guatemala, A. hickeli is found only in Mexican states of Veracruz and Oaxaca. Fir forests grow at altitudes of 2000 to 3600 m and account for only 0.16% of the total area of the country. Megastigmus (Hymenoptera: Torymidae) larvae damage up to 57% of the se...

We evaluated how the abundance and richness of frugivorous and nectarivorous bat species differs among three types of common agroecosystems (diversified coffee plantations, simple coffee plantations and pastures) in Veracruz, Mexico, that represent a gradient of structural and floristic complexity. Using mixed effects models we demonstrated that bo...
