    Distribución actual y futura de áreas potenciales para el establecimiento de plantaciones forestales de Cedrela odorata l, en la Península de Yucatán. por Manzanilla Quijada, Gyorgy Eduardo

    Publicado 2018
    “…ABSTRACT In the world and in Mexico, the main problem of forests and jungles is the overexploitation of tree species considered as valuable woods. Ecological niche models are a tool that allows us to know areas suitable for the growth and development of a species, in turn, they help predict the possible impacts of climate change on the distribution of species. …”

    Insectos asociados a biomodelos simulando cuatro condiciones de hallazgo de cadáveres. por Briones Espinoza, Héctor Eduardo

    Publicado 2018
    “…The biological material collected was transferred to the Laboratory of Entomology and Arthropods, of the Faculty of Biological Sciences for its identification and curatorial process, a database was elaborated that were analyzed by ecological indexes and non-parametric statistics. During the study, biomodels developed different periods of decomposition, due to the effect of environmental variables. …”

    Microbiota gastrointestinal y síndrome de intestino irritable por García Mazcorro, José Francisco, Cruz Valdez, Julio César, Marroquín Cardona, Alicia Guadalupe, Sánchez Casas, Rosa María

    Publicado 2014
    “…Microbiota is the correct word, defined as the community of living microorganisms residing in a determined ecological niche, and we use it, not only in the title, but throughout the article (79 times to be exact), whereas the less precise but commonly used flora is employed only 5 times.2 Secondly, the 16S ribosomal RNA (rRNA) gene is one of the components of the small subunit (30S) of the ribosome and is present in all bacteria and archaea. …”

    Camarones penaeidos y carideos como bioindicadores de contaminación y su relación con variaciones en la fisicoquímica de los sedimentos en Laguna Madre, Tamaulipas, México por Herrera Barquín, Hiram

    Publicado 2019
    “…At population and community levels, we chose caridean and penaeid shrimp communities to assess environmental health through the calculation of diversity, biotic and condition indices, which, in general, exposed poor water quality, polluted and very polluted water, significant–severe biological condition of the ecosystem, and poor ecological status. Nevertheless, these results were influenced by natural induced variations in species abundance and richness given the observed low levels of sediment pollutants content. …”
