The natural protected area Corredor Biológico Chichinautzin (CBC) has a great habitat richness directly related to its geographic, climatic, geologic location and wide altitudinal range. Environmental conditions allows the establishment of a great variety of plant communities with a monocots richness of 24 families, 123 genera and 313 species. Such...
In the present study is determined and analyzed the community structure of bats presents in the cave "El Salitre", located to 3 km in south of Los Ortices, Colima state. The vegetation consisting in relicts of tropical dry forest and the climate is warmsubhumid, with rain season from June to...
El efecto de borde, producto de la fragmentación de la vegetación por cambio de uso del suelo, puede modificar la composición y estructura de las comunidades vegetales con consecuencias críticas en el funcionamiento y la productividad forestal. El objetivo de esta tesis fue evaluar el efecto de borde sobre la...
Las plantas arvenses están asociadas a los cultivos mesoamericanos desde los albores de la agricultura; representan una fuente importante de recursos ya que satisface diversas necesidades básicas durante casi todo el ciclo agrícola (alimento, medicina y forraje, entre otros); su conocimiento y uso se ha transmitido a generaciones consecuentes. Con...
In Cactaceae, the interception of photosynthetic active radiation (PAR) differs among opposite sides of the stem, determining the availability of resources for reproduction, since it has been suggested that there is no translocation of resources between ribs. It has been shown that the production of reproductive structures in columnar cacti...
Se analiza la distribución ecológica de dos ratones silvestres del Género Peromyscus (micromamíferos) en un cuadrante de 55x45 m dentro de un bosque templado de coníferas y latifoliadas en el Parque Nacional Desierto de los Leones (PNDL). El cuadrante quedó integrado por 120 estaciones de muestreo con un área de...
Riparian ecosystems are the interface between terrestrial and aquatic ecosystems. Despite its relevance, the riparian vegetation of these ecological systems is threatened, since it is being displaced by agricultural, industrial and human settlement activities. The objective of this work was to compare the avifauna between sites that belong to different...
Las atmósferas controladas (AC) consisten en proporcionar a los productos hortofrutícolas una mezcla específica y precisamente controlada de gases en su ambiente de almacenamiento, el cual difiere de la composición de aire de la atmósfera normal. Las atmósferas modificadas difieren de las primeras en que el ambiente de almacenamiento no...
Abundance, size structure, reproduction and feeding patterns of Anchoa mitchilli were analyzed in the Pueblo Viejo lagoon, Veracruz, through 12 two-monthly 24-h cycles, in two habitats (with and without submerged vegetation). Abundance did not show differences between habitats, but seasonal significant peaks of abundance occurred during January and March. Moreover,...
The association of the Green Lynx spider, Peucetia viridans (Hentz: Oxyopidae), with Croton ciliatoglanduliferus (Ortega: Euphorbiaceae), or dominguilla as it is locally known, was analyzed in a tropical dry forest of Jalisco, in Western Mexico in 2004 and 2005. The ecological system involving the plant, its pollinators-herbivores and the Green...
