Effect of biological soil crusts on the germination of three plant species under laboratory conditions
(2014-06)"Semiarid grasslands in northeastern Mexico contain many endemic plants and animals and are an important refuge for resident and migratory animals. Here, as in many other semiarid areas, biological soil crusts are a key ... -
Effect of Cathodic Protection on Reinforced Concrete with Fly Ash Using Electrochemical Noise
(MDPI, 2021)"Corrosion of steel reinforcement is the major factor that limits the durability and serviceability performance of reinforced concrete structures. Impressed current cathodic protection (ICCP) is a widely used method to ... -
Effect of cold storage, heat, smoke and charcoal on breaking seed dormancy of Arctostaphylos pungens HBK (Ericaceae)
(2011)"We evaluated the effect of cold storage and fire-related cues on seed germination of Arctostaphylos pungens HBK (Mexican Manzanita), a common shrub in poorly managed pine-oak forests in Durango, Mexico. Because this shrub ... -
Effect of light on seed germination of succulent species from the southern Chihuahuan Desert: comparing germinability and relative light germination
(2010)"Light requirements for cactus seed germination have been considered to be associated with their life form, but this has not been thoroughly studied for other succulent species. In this study, we performed a light and ... -
Effects of burial depth on seed germination and seedling emergence of Mexican oaks: a glasshouse experiment
(2012)"Despite the interest in restoring oak forests in Mexico, very little is known about their regeneration ecology. We assessed the influence of acorn burial depth on seed germination and seedling emergence for eight Mexican ... -
Effects of experimental warming on peroxidase, nitrate reductase and glutamine synthetase activities in wheat
(Estonian University of Life Sciences, 2019)"Given the effects of climate change and its significant consequences on plant productivity, it is necessary to evaluate the enzymatic responses of the most important crops such as wheat (Triticum durum L.). We examined ... -
Effects of five Lacandon Maya agroforestry trees on soil nematode trophic group composition
(Springer, 2018)"The Lacandon Maya have managed their lands in Chiapas, Mexico for hundreds of years without long-term soil degradation by applying their traditional swidden agroforestry system. Lacandon land managers plant and care for ... -
Effects of shade on germination traits of the endangered cycad Dioon edule (Zamiaceae)
(2016-03)"The endangered cycad Dioon edule requires shade provided by filtered sunlight under the canopy of trees or maternal plants during initial growth stages. It is known that germination improves under shade, but there is no ... -
Effects of spine-shading on aspects of photosynthesis for three cactus species
(2016-06)"We evaluated the effect of spine removal on three cactus species varying in spine-shading of stems. Turbinicarpus schmiedickeanus showed the greater spine shading (c. 61 %), followed by Mammillaria zephyranthoides (43 %), ... -
Effects of surface-engineered nanoparticle-based dispersants for marine oil spills on the model organism Artemia franciscana
(American Chemical Society, 2014)"Fine particles are under active consideration as alternatives to chemical dispersants for large-scale petroleum spills. Fine carbon particles with engineered surface chemistry have been shown to stabilize oil-in-water ... -
Effects of wetting and drying cycles on the germination of nine species of the Chihuahuan Desert
(2016-06)"Plants from drylands have developed strategies to germinate even in places where available humidity is sporadic with large periods of drought. Previous works determined germination of cacti species as a response to ... -
Electrodos de pasta de carbón modificados con partículas de hierro y su aplicación como sensores en la detección de As(V)
(2017)"La detección electroquímica de arsénico(V) fue evaluada en un electrodo de pasta de carbón modificado con partículas de hidro(óxidos) de hierro en medio electrolítico de NaNO3. El polvo de grafito modificado se preparó ... -
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 ... -
Enhancing saccharification of Agave tequilana bagasse by oxidative delignification and enzymatic synergism for the production of hydrogen and methane
(Elsevier, 2018)"Agave tequilana bagasse is a suitable lignocellulosic residue for energy production. However, the presence of lignin and the heterogeneous structure of hemicellulose may hinder the availability of polysaccharides. In this ... -
Epiphytic orchids Stanhopea tigrina and Prosthechea cochleata are differentially affected by drought in a subtropical cloud forest
(Institute of Experimental Botany CAS, 2019)"We investigated the physiological responses of two epiphytic orchids under three light regimes of 20, 50, and 70% of total daily radiation under drought and rewatering conditions. Stanhopea tigrina was the one more affected ... -
Escontria chiotilla (Cactaceae): fruit development, maturation and harvest index
(2015)"Introduction. The edible fruit of jiotilla (Escontria chiotilla (Weber) Rose), a cactus endemic to Central Mexico, mature asynchronously and are characterized by the presence of bracts in the fruit peel (pericarpel). In ... -
