Effect of induced global warming on survival and performance of succulent species from Southern Chihuahuan Desert
(2016)
"Numerous ecological studies have assessed the potential consequences of climate warming within several ecosystems worldwide. However, the impact of global warming on desert plants is still little studied. Most predictions ...
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.) ...
Role of the intrinsic properties of partially reduced graphene oxides on the chemical transformation of iopromide
(Elsevier, 2016)
"The role of the intrinsic properties of graphene oxide (GO) and partially reduced graphene oxide (rGO), and their use as redox mediator (RM) is reported, for the first time, on the chemical transformation of iopromide ...
Rangeland systems in developing nations: conceptual advances and societal implications
(Springer, 2017)
"Developing-country rangelands are vast and diverse. They are home to millions who are often poor, politically marginalized, and dependent on livestock for survival. Here we summarize our experiences from six case-study ...

Role of indigenous microbiota from heavily contaminated sediments in the bioprecipitation of arsenic
(Elsevier, 2017)
"High arsenic concentrations have been detected in alluvial aquifers of arid and semi-arid zones in Mexico. This work describes the potential of microbial arsenate reduction of the indigenous community present in sediments ...
Influence of human activities on some medium and large-sized mammals’ richness and abundance in the Lacandon Rainforest
(2016)
"We evaluated the influence of six human activities (related variables) on the richness and abundance of large and medium-sized mammals in the southern portion of the Lacandon Rainforest, including protected and non-protected ...
NMR analysis and crystal structure of hydroxyclerodanes from Mexican Salvia species
(2017)
"NMR and single crystal X-ray diffraction analysis of seven clerodanes from Mexican Salvia species was performed. We focused on clerodanes with tertiary hydroxyl group at C-4, C-8, and C-10, in which the establishment of ...
Efecto del Mn en el hábito cristalino de los (oxi)hidróxidos de hierro anclados en carbón activado: adsorción de As(V)
(2016)
"Se anclaron (oxi)hidróxidos de hierro sobre la superficie del carbón activado por
medio de un proceso hidrotermal asistido por microondas (M-H) para
incrementar su capacidad de adsorción del arsénico en solución acuosa. ...
Influencia de la estructura vegetal, del paisaje y disponibilidad de presas sobre la ocupación de hábitat del cernícalo americano (Falco sparverius) en el Altiplano Potosino Zacatecano
(2016)
"El cernícalo americano es un ave rapaz con una amplia distribución en el
continente Americano. Las poblaciones del norte del continente han disminuido su
abundancia en los últimos años y se ha considerado que la causa de ...
