Carbonaceous and protein constituents in dairy wastewater lead to a differentiated current generation in microbial fuel cells (MFCs)
(2014)"The effect of real dairy wastewater (DWW) additions on the current density generated by a bioanode was evaluated in a half cell configuration under potentiostatic control, thus simulating the anodic chamber of a Microbial ... -
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 ... -
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 ... -
The andean forest soil seed bank in two successional stages in northeastern Colombia
(2016-12)"Background: Soil seed banks play an important role in post-disturbance regeneration and succession of species from different successional stages. Questions: 1) What is the most effective method for determining the ... -

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 %), ... -
The relevance of burial to evade acorn predation in an oak forest affected by habitat loss and land use changes
(2014-06)"Seed burial was proposed as an effective mechanism to evade seed predation in continuous forests. However, the relevance of burial as a mechanism to evade seed predators may be compromised in fragmented forests intensely ... -
Differential allelopathy between genders of an invasive dioecious tree on desert plants
(2016-06)"The Peruvian peppertree (Schinus molle) is a dioecious species from South America that was introduced into central Mexico five centuries ago. This tree has invaded abandoned agricultural fields from semiarid regions, where ... -
Estructura de un bosque natural perturbado de Pinus tropicalis Morelet en Galalón, Cuba
(2014-09)"Los bosques naturales de Pinus tropicalis Morelet en Cuba han sido alterados por prácticas inadecuadas de aprovechamiento forestal. Esta investigación tiene el objetivo de caracterizar la estructura de un bosque perturbado ... -
Inmovilización de un mediador redox en carbón activado y su aplicación en la reducción biológica de colorantes azo
(2011)"El presente estudio reporta por primera vez la inmovilización de un catalizador con capacidad para transferir electrones (mediador redox) en carbón activado (CA). El CA granular estudiado presentó una gran capacidad de ... -
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 ... -
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 ... -
