Effect on hemoparasite infection, song structure, and population genetics in the Black-throated sparrow (Amphispiza bilineata) of habitat modification at a portion of the Mexican highland plateau
(2017-11)"La comunidad científica ha buscado estrategias para evaluar los impactos de las actividades humanas en el sistema del planeta Tierra. La degradación del hábitat en las tierras secas se caracteriza por una reducción en ... -
Effect on the variation of root exudates from Agave lechuguilla Torr. over the diversity and activity of nutrient-improvement rhizobacteria
(2022-03-01)"The wide distribution of Agave lechuguilla Torrey has drawn attention to the mechanisms that enable its survival in the Chihuahuan Desert. This success could be attributed to the association of lechuguilla with plant-growth ... -
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 ... -
Electroadsorción de fluoruros por electrodos de carbón activado modificados con Lantano(III)
