Abstract. Large isolated trees are a common feature of the agricultural landscape in humid tropical regions originally covered by rain forest. These primarily used as source shade for cattle and people. 13 pastures (totalling ca. 80 ha) currently pasture were studied. In them, we registered 265 belonging to 57 species. 50 most frequent species ( Ficus spp. n = 30 Nectandra ambigens 20) selected examine influence on floristic composition vegetation structure pastures. At each tree, three 4–m...
In the highly fragmented landscape of Los Tuxtlas, Mexico, we studied seed rain, bank, and vegetation established beneath canopies five fig trees (Ficus spp.) isolated in pastures. The area canopy each tree was enclosed with a barbed wire fence to exclude cattle, weeding machete herbicide spraying were stopped. Annual rain 20,936 seeds (1066 seeds/m2) belonging 149 species. Seed dominated by woody species dispersed frugivorous birds bats. Most captured (94%) small (seed diam < 3 mm). A total...
Abstract Forest recovery in tropical pastures is limited by seed dispersal, mainly because the dispersers of woody plants avoid deforested areas. In Los Tuxtlas, Mexico, we fenced isolated fig trees that had been left to provide shade pastures. We monitored deposition under their canopies over a year and sampled established vegetation after 3 y. Dispersal distances were estimated for captured seeds plants, assuming nearest conspecific adult rooted within 75 m tree was mother. Seventy shrub...
In tropical dry landscapes, biodiversity conservation is dependent upon both the protection of natural areas and sustainable management agricultural matrix. We analyzed taxonomic, species functional group diversity ants in three neighboring habitats with different degrees anthropic disturbance Veracruz, Mexico. A total 34,957 ant workers belonging to 89 species, 34 genera, 19 tribes 7 subfamilies were recorded. Primary forest had highest richness most even distribution among taxonomic...
Abstract Ectoparasitism in bats seems to be influenced strongly by the type of roost preferred hosts, and group size; however, effect habitat loss fragmentation on prevalence ectoparasites has scarcely been studied. In northeastern Yucatan, Mexico, we estimated infestation Streblidae flies three phyllostomid bat species with different preferences (caves, trees, or both) two types landscape matrices (tropical semi‐deciduous forest man‐made pastures) that differed area cover number fragments....
Climate change is recognized as an important threat to global biodiversity because it increases the risk of extinction many species on planet. Mexico a megadiverse country and native tree such red cedar (Cedrela odorata) can be used maintain forests while helping mitigate climate change, considered fast growing pioneer with great economic potential in forestry industry. In order assess possible shifts areas suitable for C. odorata plantations ecological niche models, we MaxLike algorithm,...
La Reserva de la Biosfera Los Tuxtlas (RBLT) alberga los últimos remanentes bosque tropical perennifolio (BTP) y mesófilo montaña (BMM) en llanura costera del golfo México. Sin embargo, las últimas décadas ha perdido ~ 60% su cobertura forestal. información precisa detallada sobre dinámica cambio uso suelo es fundamental para implementar planes manejo/conservación pertinentes a situación actual futura una región. El objetivo trabajo fue determinar reciente cambios espacio-temporales vegetal,...
Se analiza la estructura y composición florística de 13 potreros establecidos en áreas originalmente cubiertas por selva alta perennifolia, Sierra Los Tuxtlas, Veracruz. En ellos es común encontrar árboles aislados que su mayoría son remanentes selva, dejados pie porque constituyen importantes fuentes sombra, alimento (principalmente frutos), leña o madera. La los estudiados muy heterogénea, debido a presencia grandes interior, cuales sitios deposición semillas dispersadas aves murciélagos...
RESUMEN Existen pocos datos sobre la dispersión de semillas por aves frugivoras en paisajes fragmentados que se originaron selvas tropicales secas, comparación a los existentes para húmedas. En este trabajo evaluamos el efecto las frugfvoras un paisaje fragmentado localizado Veracruz, México, ocupado actualmente remanentes mediana y baja, pastizal, matorrales dunas arena. Para ello determinamos cuatro caracteristicas relacionadas con aves: especies plantas interactuantes, caracterfsticas...

Forest fragmentation reduces the amount of forest cover and negatively affects habitat quality remnants. Landscape attributes should therefore be evaluated together to improve our understanding how fauna respond fragmentation. We patch (vegetation structure) landscape characteristics influence abundance phytophagous bats in two contrasting types that differ percent matrix type: landscapes dominated by man-made pastures with large tracts continuous (tropical semi-deciduous forest). Bats were...
This study describes the diversity of ectoparasitic bat flies (Diptera: Streblidae) in state Yucatan, Mexico. Fieldwork was carried out from June 2010 to January 2012 seven municipalities where 13 sampling sites were selected capture bats using mist nets. Over 156 nights a total 910 captured; these belonged 19 species four families: Mormoopidae, Phyllostomidae, Natalidae, and Vespertilionidae. Phyllostomidae richest family (13 species), followed by Mormoopidae (3 spp.), Vespertilionidae (2...
251 One of the greatest challenges for Latin America and Caribbean, most biologically culturally diverse region in world, is to halt loss species caused by habitat destruction land degradation. Up now, setting aside protected natural areas considered effective alternative conserve biodiversity. Protected areas, however, are under increasing assault agricultural, silvicultural industrial development that surround isolate them, reducing their quality at landscape scale. Among different types...
Se hizo un inventario de especies plantas fanerógamas y pteridofitas en potreros áreas desprovistas árboles, la zona del volcán San Martín Tuxtla, Los Tuxtlas, Veracruz. Con el fin tener composición florística más completa posible, se realizaron muestreos durante temporada seca lluvia año 1992, dos localidades: ejido Balzapote colonia agrícola-ganadera La Palma. En cada localidad seleccionaron cinco dominados por pastos nativas (conocidos como grama) que prevalece gramínea introducida...
Los acahuales (i.e. selvas secundarias) de zonas tropicales secas o estacionales, suelen ser pobres en especies arbóreas y dominados por unas cuantas arbustos árboles pioneros, usualmente dispersados viento, siendo notable la ausencia plantas del dosel cuyas semillas relativamente grandes dependen vectores animales para su dispersión. Varios estudios han encontrado que siembra directa zoócoras con grandes, pastizales abandonados puede una práctica exitosa enriquecer acelerar sucesión...
Context Dry forests usually have a marked seasonality in resource availability; as consequence, wildlife is subjected to drastic changes food availability during the year. The presence of high-quality sites that provide lean periods crucial these habitats, especially human-modified landscapes where resources are limited and scattered. Aims We assessed whether seasonal fluctuations fruit two contrasting landscape matrices (continuous tropical semi-deciduous forest pasture) affect diet...
