Human impacts and aridity differentially alter soil N availability in drylands worldwide
(Wiley, 2016)"Aims Climate and human impacts are changing the nitrogen (N) inputs and losses in terrestrial ecosystems. However, it is largely unknown how these two major drivers of global change will simultaneously influence the N ... -
Factores que influyen en la ocupación de hábitat en la temporada de reproducción del gorrión de Worthen (Spizella wortheni) en el Altiplano Potosino
(2019-09-17)"El Gorrión de Worthen (Spizella wortheni), es una especie endémica y amenazada del Altiplano Mexicano que se asocia a pastizales naturales y matorrales. Su rango de distribución ha disminuido significativamente en los ... -
Impact of emerging, high-production-volume graphene-based materials on the bioavailability of benzo(a)pyrene to brine shrimp and fish liver cells
(Royal Society of Chemistry, 2018)"With increasing commercialization of high volume, two-dimensional carbon nanomaterials comes a greater likelihood of environmental release. In aquatic environments, black carbon binds contaminants like aromatic hydrocarbons, ... -
Graphene oxide triggers mass transfer limitations on the methanogenic activity of an anaerobic consortium with a particulate substrate
(Elsevier, 2018)"Graphene oxide (GO) is an emerging nanomaterial widely used in many manufacturing applications, which is frequently discharged in many industrial effluents eventually reaching biological wastewater treatment systems (WWTS). ... -
Screening of commercial sorbents for the removal of phosphates from water and modeling by molecular simulation
(Elsevier, 2018)"Eight commercial sorbents of different origin and nature were studied in the present work for the removal of phosphate from water using synthetic solutions and a wastewater from an anodizing company. The materials included ... -
Improved conductivity and anti(bio)fouling of cation exchange membranes by AgNPs-GO nanocomposites
(Elsevier, 2018)"Nafion and Ultrex membranes were modified with nanocomposites (NCs) of silver nanoparticles (AgNPs) immobilized on graphene oxide (GO) as a thin film, using a polydopamine adhesive (pda). The morphological, physicochemical, ... -
Soil fungal abundance and plant functional traits drive fertile island formation in global drylands
(Wiley, 2018)"Dryland vegetation is characterized by discrete plant patches that accumulate and capture soil resources under their canopies. These fertile islands are major drivers of dryland ecosystem structure and functioning, yet ... -
Chitosan-macroalgae biocomposites as potential adsorbents of water-soluble hydrocarbons: organic matter and ionic strength effects
(Elsevier, 2018)"Nowadays the recovery of low-molecular soluble aromatic hydrocarbons (HCs) released into natural bodies of water continues to be a challenging task. These contaminants bring sever consequences to the environment and to ... -
Sulfate reduction at acidic conditions: from the sediment to the reactor
(2019-09)"Acid mine drainage is water polluted with heavy metals, sulfate, and acid as the result of some mining activities. Due its physicochemical characteristics, acid mine drainage is toxic, recalcitrant and difficult to treat. ... -
Enhancement of perchlorate removal from groundwater by cationic granular activated carbon: Effect of preparation protocol and surface properties
(Elsevier, 2018)"In order to obtain a high adsorption capacity for perchlorate, the epoxide-forming quaternary ammonium (EQA) compounds were chemically bonded onto granular activated carbon (GAC) surface by cationic reaction. The optimum ... -

Climate change in forest ecosystems: A field experiment addressing the effects of raising temperature and reduced rainfall on early life cycle stages of oaks
(Elsevier, 2018)"Higher temperatures and reduced rainfalls that are expected with the advance of climate change can impair the emergence and establishment of tree seedlings in forest ecosystems. These climatic changes can also decrease ... -
TRUE GRASP: Actors visualize and explore hidden limitations of an apparent win-win land management strategy in a MAB reserve
(Elsevier, 2018)"Win-win solutions might be short-lived. Government permission for smallholder farmers to extract and sell resin from a pine savanna biosphere-reserve in Mexico has settled a long dispute among different stakeholders in ... -
Rheological behavior from light to heavy oils: construction of master curves
(American Chemical Society, 2016)"In this work, the rheological behavior of heavy and light stabilized (dead) oils is presented. The viscosity measurements were carried out in two different apparatuses to ensure the repetitiveness and accuracy: a Stabinger ... -
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 ... -
