Seasonal ecophysiological variations of Echinocactus platyacanthus, a specially protected cactus species: Effect of induced climate warming
(Elsevier, 2021)"Cactus species are key components in American deserts and have a high socioeconomic value. Climate change exerts a threat to biodiversity, structure and functioning within deserts and many cactus species are predicted to ... -
Seasonal Precipitation Legacy Effects Determine the Carbon Balance of a Semiarid Grassland
(Wiley, 2019)"Semiarid grasslands are water‐limited ecosystems where precipitation (PPT) controls the onset and duration of the growing season; however, this variable does not fully explain interannual variability of productivity at ... -
Seed germination of Opuntia species from an aridity gradient in Central Mexico
(2010)"In the Mexican highlands there are several aridity gradients affecting Opuntia species composition and its biological function. Since environmental variations can affect plant traits like seed morphology as well as related ... -
Seed integrity, effect of temperature and storage time on germination of Populus luziarum and P. primaveralepensis, endangered subtropical species from Mexico
(Sociedad Botánica de México, 2022)"Background: Populus luziarum and P. primaveralepensis are endemic species of western Mexico; growing in riparian forests they are critically endangered. The best way to conserve their seeds is unknown, which could be ... -
Seed traits and germination in the Cactaceae family: A review across Americas
(Sociedad Botánica de México, 2020)"Background: Cactaceae is the fifth taxonomic group with the highest proportion of threatened species and among the angiosperms, the most vulnerable to human disturbance. One way to contribute to the preservation of this ... -
Semillas de cáctaceas: factores internos y externos que influyen en su germinación
(2020)"Las semillas representan uno de los estadios más cruciales en el ciclo de vida de las plantas, ya que de ellas depende el establecimiento de nuevos individuos y la perpetuación de la especie. La germinación de semillas ... -
Shared pollinators and sequential flowering phenologies in two sympatric cactus species
(Meise Botanic GardenRoyal Botanical Society of Belgium, 2021)"Background and aims – The reproductive characteristics of sympatric Cactaceae are important because they help to understand interfering or facilitating mechanisms that allow their coexistence. Globose Cactaceae show ... -
Shifts in Climatic Niche Occupation in Astrophytum Coahuilense (H. Möller) Kayser and Its Potential Distribution in Mexico
(MDPI, 2019)"It has frequently been reported that species with strong niche conservatism will not be able to adapt to new climatic conditions, so they must migrate or go extinct. We have evaluated the shifts in climatic niche occupation ... -
Shopping for Ecological Indices? On the Use of Incidence-Based Species Compositional Similarity Measures
(MDPI, 2022)"β-diversity has been under continuous debate, with a current need to better understand the way in which a new wave of measures work. We assessed the results of 12 incidence-based β-diversity indices. Our results of gradual ... -

(2009)"Los incendios forestales son un problema ambiental global que afecta los ecosistemas forestales del planeta. La quema de biomasa ocasiona daños en la vegetación, pérdida de especies animales, pérdida de cobertura de suelo ... -
Simultaneous adsorption of Pb(Ii)-Cd(Ii), Pb(Ii)-phenol, and Cd(Ii)-phenol by activated carbon cloth in aqueous solution
(2015-01)"The aim of the present work was to determine the effect of the simultaneous adsorption of lead(II)-cadmium(II), lead(II)-phenol, and cadmium(II)-phenol by activated carbon cloths (ACCs). Three commercial ACCs were ... -
Simultaneous nitrification and autotrophic denitrification in fluidized bed reactors using pyrite and elemental sulfur as electron donors
(Elsevier, 2023)In this study, simultaneous nitrification and autotrophic denitrification (SNAD) with either elemental sulfur or pyrite were investigated in fluidized bed reactors in mesophilic conditions. The reactor performance was ... -
