Biorecovery of Metals from a Stainless Steel Industrial Effluent through Denitrification Performed in a Novel Anaerobic Swirling Fluidized Membrane Bioreactor (ASFMBR)
(American Chemical Society, 2020)"A novel technology was developed for the treatment of a stainless steel wastewater, which contains high nitrate concentration (6.8 g N-NO3–/L), acidic pH (pH 3.3), and high concentration of metals. Denitrification was ... -
Broader Impacts for Ecologists: Biological Soil Crust as a Model System for Education
(Frontiers Media S.A., 2021)"Biological soil crusts (biocrusts) are a complex community of algae, cyanobacteria, lichens, bryophytes, and assorted bacteria, fungi, archaea, and bacteriophages that colonize the soil surface. Biocrusts are particularly ... -
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 ... -
Carbamazepine degradation by visible-light-driven photocatalyst Ag3PO4/GO: Mechanism and pathway
(Elsevier, 2022)"Carbamazepine (CBZ), as one of the most frequently detected pharmaceuticals, is of great concern due to its potential impact on the ecosystem and human health. This study provides an effective approach to remove CBZ by ... -
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
(2016-03)"Ecologists have been largely interested in the description and understanding of the power scaling relationships between body size and abundance of organisms. Many studies have focused on estimating the exponents of these ... -
Chitosan selectivity for removing cadmium (II), copper (II), and lead (II) from aqueous phase: pH and organic matter effect
(Elsevier B.V., 2009-02)"The aim of this study was to investigate the selectivity of chitosan for cadmium, copper and lead in the presence and absence of natural organic matter (NOM) in different pH solutions. Adsorption isotherms of one and three ... -
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 ... -
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 ... -
Coconut endocarp and mesocarp as both biosorbents of dissolved hydrocarbons in fuel spills and as a power source when exhausted
(2018-04)"Health and environmental problems associated with the presence of toxic aromatic compounds in water from oil spills have motivated research to develop effective and economically viable strategies to remove these pollutants. ... -
Combined effect of water potential and temperature on seed germination and seedling development of cacti from a mesic Argentine ecosystem
(Elsevier, 2017)"Global climatic change will be associated with an increase of droughts and heat waves, which can affect seed germination and plant population dynamics. Cactus species from mesic ecosystems are likely to be more affected ... -
Community structure of a southern Chihuahuan Desert grassland under different grazing pressures
(Elsevier, 2009)"The effect of different grazing intensities on the semiarid grasslands of the southern Chihuahuan Desert was studied using a fence-line contrast between a moderately grazed cattle ranch, from which goats and sheep had ... -
