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

“…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. …”

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

“…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. …”

Taxonomía, distribución e importancia de las algas de Nuevo León por Aguirre Cavazos, Diana Elena

“…For Nuevo León, there were only 21 specific registers until 2006 which represent scarcely a 0.64% of the country richness. Due to ecological and economical importance of certain algal groups or species, in this study, we sought to determine the presence of species of economic importance and indicators in different freshwater bodies of the state of Nuevo León, as well as identify them and know their taxonomic status. …”

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

“…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. …”
