(2015)"La contaminación del agua por fluoruros (F- ) y arsénico (As) es un problema de importancia mundial, ya que el agua subterránea de varios países excede los límites permisibles establecidos por la Organización Mundial de ... -
Agave bagasse biorefinery: processing and perspectives
(Springer, 2018)"Agave bagasse (AB) is the main solid waste generated by the tequila industry in Mexico, which is an environmental concern due to its considerable volume of production (377,000 Ton in 2016). AB is a lignocellulosic biomass ... -
Algunos aspectos sobre el nodrizaje en Astrophytum myriostigma Lem. (1839) (Cactae: Cactaceae), en la Sierra El Sarnoso, Durango, México
(2009)"La condición de nodrizaje es una estrategia de plantas de zonas áridas, radica en que los propágulos se establecen bajo plantas o rocas (consideradas nodrizas), obteniendo los beneficios de disminución de la temperatura, ... -
Allometry of root branching and its relationship to root morphological and functional traits in three range grasses
(Oxford University Press, 2011)"The study of proportional relationships between size, shape, and function of part of or the whole organism is traditionally known as allometry. Examination of correlative changes in the size of interbranch distances (IBDs) ... -
An overview of reclaimed wastewater reuse in gold heap leaching
(Taylor & Francis, 2016)"The intensive use of groundwater by the gold mining industry is an important sustainability concern, especially in arid and semiarid regions where groundwater is a scarce resource. Alternatives, such as water reuse, ... -
Anaerobic methane oxidation driven by microbial reduction of natural organic matter in a tropical wetland
(2017-06)"Wetlands constitute the main natural source of methane on Earth due to their high content of natural organic matter (NOM), but key drivers, such as electron acceptors, supporting methanotrophic activities in these habitats ... -
Análisis del concepto de sostenibilidad en la legislación mexicana usando el paradigma de desarrollo de las zonas secas
(2012)"Utilizando el paradigma de Desarrollo de las Zonas Secas (DDP, por sus siglas in ingles) este trabajo analiza la relación entre el discurso legal, el desempeño de las instituciones gubernamentales y el manejo de sistemas ... -
Antioxidant activity and in vitro antiglycation of the fruit of Spondias purpurea
(2018)"Hyperglycemia in diabetes mellitus causes irreversible life-threatening micro- and macrovascular complications. There is evidence that the glycation reaction leads to a chemical modification of the proteins contributing ... -
Are seed mass and seedling size and shape related to altitude? Evidence in Gymnocalycium monvillei (Cactaceae)
(Canadian Science Publishing, 2015)"Several studies reported a negative relationship between altitude and seed mass. In cactus species, seed mass has been also related to seedling morphology (size and shape). Here we studied Gymnocalycium monvillei (Lem.) ... -
Beetle diversity in fragmented thornscrub and isolated trees
(2017-02)"Due to land use change mainly for induced agriculture, Tamaulipan thornscrubin northeast Mexico has been cleared and transformed into small patches of vegetation as small as isolated trees surrounded by agricultural fields. ... -
Biomasa aérea de Vochysia guatemalensis en una selva alta perennifolia de La Chinantla, Oaxaca
(Universidad Juárez Autónoma de Tabasco, 2017)"Se estimó la biomasa aérea de Vochysia guatemalensis Donn. Smith., una especie de importancia ecológica y económica en el sur-sureste de México. Se derribaron siete árboles de cuatro categorías diamétricas (10, 15, 20 y ... -
Bioreactores empacados con fibras de carbón activado como mediadores redox en la biotransformación anaerobia de 4-Nitrofenol hacia 4-Aminofenol
(2017)"La función de los grupos funcionales superficiales sobre los carbones activados es de gran interés en procesos biológicos con actividad redox porque tales grupos pueden incrementar la eficiencia de biotransformación de ... -
Butterfly conservation within cities: a landscape scale approach integrating natural habitats and abandoned fields in central Mexico
(2016-06)"Growing urbanization and the expansion of the agricultural frontier in tropical ecosystems have generated patchy landscapes composed of remnants of natural habitats and abandoned fields. This scenario offers an opportunity ... -
Carbonaceous and protein constituents in dairy wastewater lead to a differentiated current generation in microbial fuel cells (MFCs)
(2014)"The effect of real dairy wastewater (DWW) additions on the current density generated by a bioanode was evaluated in a half cell configuration under potentiostatic control, thus simulating the anodic chamber of a Microbial ... -
Changes in body size spectra of benthic caridean shrimps (Decapoda: Caridea) and snails (Gastropoda) as response to seasonal variability
