Germinación, infestación y viabilidad en bellotas de Quercus polymorpha (Schltdl. & Cham.) tras un año de almacenamiento
(2013)"Los encinos blancos tienen semillas recalcitrantes que se mantienen viables por corto tiempo. Sin embargo, esta información es escasa para encinos mexicanos. Este es el caso de Quercus polymorpha, una especie tolerante a ... -
Germinación, supervivencia y respuestas funcionales de Quercus Eduardii (Fagaceae) en escenarios de cambio de uso de suelo y de cambio climático
(2017)"Human-induced climate change can modify the functioning of forest ecosystems. Tree recruitment is sensitive to this change and, in Mexico, oak trees can be particular threatened (Quercus spp., Fagaceae). Further, Mexican ... -
Germination characteristics of Gymnocalycium monvillei (Cactaceae) along its entire altitudinal range
(2017-04)"Germination characteristics are important for understanding how species cope with environmental variation. The aims of this work were to analyze the effect of different temperatures (25 and 32 °C), water potentials (0, ... -
Germination of seven species of shrubs in semiarid central Mexico: Effect of drought and seed size
(Sociedad Botánica de México, 2020)"Background: In semiarid ecosystems, many plant species are tolerant to drought. However, increased aridity as a result of climatic change could modify the capacity of germination and establishment. Hypothesis: Under ... -
Gold recovery from very dilute solutions from a mine in closing process: adsorption-desorption onto carbon materials
(Elsevier B.V., 2017-08)"The aurocyanide complex recovery by precipitation with zinc decreases when gold concentration drops to < 20 μg L− 1. Therefore, a technology capable of recovering gold from very diluted solution is necessary. Adsorption ... -
Graphene oxide triggers mass transfer limitations on the methanogenic activity of an anaerobic consortium with a particulate substrate
(Elsevier, 2018)"Graphene oxide (GO) is an emerging nanomaterial widely used in many manufacturing applications, which is frequently discharged in many industrial effluents eventually reaching biological wastewater treatment systems (WWTS). ... -
Grazing effects on fungal root symbionts and C and N storage in a shortgrass prairie in Central Mexico.
(2005)"La ganadería extensiva es una de las principales formas de uso de suelo en los pastizales semiáridos del centro de México. A pesar de la vasta extensión y de su alta degradación la cual está asociada al sobrepastoreo, la ... -
Growth and ecophysiology of succulent seedlings under the protection of nurse plants in the Southern Chihuahuan Desert
(2015-03)"In arid zones, light and water are two important factors that limit seedling development. The shade provided by nurse plants can reduce overheating, excessive transpiration, and photoinhibition in protege seedlings. The ... -
Habitat suitability models to make conservation decisions based on areas of high species richness and endemism
(Springer, 2018)"Biodiversity positively relates with the provisioning of ecosystem services and preserving areas with elevated diversity of highly-functional species could help to ensure human well-being. Most studies addressed to make ... -
Haemosporidian parasite prevalence, parasitemia, and diversity in three resident bird species at a shrubland dominated landscape of the Mexican highland plateau
(2016-05)"Background: Studies of avian haemosporidians allow understanding how these parasites affect wild bird populations, and if their presence is related to factors such as habitat loss, degradation and fragmentation, and ... -
Heat shock effect in breaking physical dormancy in seeds of Lupinus elegans and L. rotundiflorus from Jalisco, Mexico
(2014-03)"Most Lupinus spp. (Fabaceae) grow in pine and pine-oak forests with natural and induced fires, and their seeds have physical dormancy, which could be broken in response to appropriate environmental signals, such as high ... -
Hidrocoria en semillas de Agave victoriae-reginae T. Moore, especie en peligro de extinción: Morfología y anatomía como facilitadores de la hidro-dispersión y germinación
(2017)"Agave victoriae-reginae es una especie endémica del Desierto Chihuahuense y crece sobre paredes en cañones. Posee semillas aplanadas que pueden ser dispersadas durante eventos episódicos de inundación. La presente ... -
High tolerance to high-light conditions for the protected species Ariocarpus kotschoubeyanus (Cactaceae)
(2017-07)"We determined the seasonal ecophysiological performance under perennial plants and under high solar radiation for adult individuals from the "living rock" cactus Ariocarpus kotschoubeyanus, which occurs equally under nurse ... -
Human impacts and aridity differentially alter soil N availability in drylands worldwide
(Wiley, 2016)"Aims Climate and human impacts are changing the nitrogen (N) inputs and losses in terrestrial ecosystems. However, it is largely unknown how these two major drivers of global change will simultaneously influence the N ... -
Humic Substances Mediate Anaerobic Methane Oxidation Linked to Nitrous Oxide Reduction in Wetland Sediments
(Frontiers Media S.A., 2020)"Humic substances are redox-active organic molecules, which play pivotal roles in several biogeochemical cycles due to their electron-transferring capacity involving multiple abiotic and microbial transformations. Based ... -
Hydrogen metabolic patterns driven by Clostridium-Streptococcus community shifts in a continuous stirred tank reactor
(Springer, 2018)"The hydrogen (H2) production efficiency in dark fermentation systems is strongly dependent on the occurrence of metabolic pathways derived from the selection of microbial species that either consume molecular H2 or ... -
Identificación del "hueco de agua" y su relación con la latencia física en semillas del género Lupinus spp.de Jalisco,México.
(2011)"Latencia de semillas es el estado en el cual una semilla viable no germina aunque se le coloque en condiciones de humedad, temperatura y concentración de oxígeno idóneas para hacerlo. Se considera que la función principal ... -
Immobilization of bimetallic oxyhydroxides on graphitic matrices to remove arsenate and fluorides from water
(2022-06-28)"The excess of arsenic and fluoride in the water has led to serious health problems, which is why they are considered a priority pollutant to be eliminated from drinking water by the World Health Organization (WHO). Various ... -
