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

    Published 2018
    “…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. …”

    Efecto potenciador de inhibidores de fenoloxidasas (PO) en la infección de hongos entomopatógenos sobre el gusano soldado Spodoptera exigua Hübner (Lepidoptera: Noctuidae). by Pérez Rodríguez, Ricardo

    Published 2017
    “…ABSTRACT: Nowadays, the main concern for the pest control consist reduce the use of chemical insecticides as a result of a series of adverse effects that these cause (resistance, resurgence, non-selectivity, environmental damage and human health), therefore, nowadays biological control represents an ecological alternative to chemical insecticides. Entomopathogenic fungi represent an alternative within the biological control area, as these were the first microorganisms reported as causing insect diseases. …”

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

    Published 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. …”
