A Systematic Review on Opuntia (Cactaceae; Opuntioideae) Flower-Visiting Insects in the World with Emphasis on Mexico: Implications for Biodiversity Conservation
(MDPI, 2022)"Opuntia spp. are cacti with high ecological, economic and conservation interest in semiarid environments, particularly in Mexico. We conducted a systematic search of the existing peer-reviewed literature about the state ... -
Allometry of root branching and its relationship to root morphological and functional traits in three range grasses
(Oxford University Press, 2011)"The study of proportional relationships between size, shape, and function of part of or the whole organism is traditionally known as allometry. Examination of correlative changes in the size of interbranch distances (IBDs) ... -
Are nurse plants useful for facilitating the reintroduction of mid- and late successional tree species in tropical montane cloud forests?
(Sociedad Botánica de México, 2023)Background: In Mexico, where 50 % of the original Tropical montane cloud forest (TMCF) has been lost due to human activities, the restoration of these forests is essential. Questions and/or hypotheses: (1) Liquidambar ... -
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.) ... -
Community structure of a southern Chihuahuan Desert grassland under different grazing pressures
(Elsevier, 2009)"The effect of different grazing intensities on the semiarid grasslands of the southern Chihuahuan Desert was studied using a fence-line contrast between a moderately grazed cattle ranch, from which goats and sheep had ... -
Coupled plant traits adapted to wetting/drying cycles of substrates co?define niche multidimensionality
(Wiley, 2020)"Theories attempting to explain species coexistence in plant communities have argued in favour of species' capacities to occupy a multidimensional niche with spatial, temporal and biotic axes. We used the concept of ... -
Densidad de semillas y plántulas de Zanthoxylum fagara en México y Zanthoxylum coco en Argentina: influencia de plantas bajo las cuales ocurren y borde de la vegetación
(Sociedad Botánica de México, 2021)"Antecedentes: La distribución de plantas depende de dispersores que transportan semillas a hábitats adecuados y de plantas que faciliten o inhiban germinación y establecimiento. Es importante conocer cómo estos factores ... -
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 ... -
Distribution Patterns of Invasive Buffelgrass (Cenchrus ciliaris) in Mexico Estimated with Climate Niche Models under the Current and Future Climate
(MDPI, 2022)"In Mexico, buffelgrass (Cenchrus ciliaris) was introduced in the middle of the 20th century. Currently, buffelgrass has become an invasive species and has colonized various ecosystems in the country. In addition to its ... -
Effect of aridity on species assembly in gypsum drylands: a response mediated by the soil affinity of species
(Oxford University Press, 2020)"Previous studies found that plant communities on infertile soils are relatively resistant to climatic variation due to stress tolerance adaptations. However, the species assemblies in gypsum soil habitats require further ... -
Effect of storage time and pre-germination treatments on nine native herbaceous species with the potential to restore degraded soils of La Primavera Forest, Jalisco
(Sociedad Botánica de México, 2023)Background: Percentage and speed of germination are crucial factors that can restrict processes involved in plant succession during ecological restora-tion. Pre-germination treatments and the effect of storage time on ... -
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 %), ... -
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 ... -
Experimental drought on seedlings in a canopy gap and understory of a tropical cloud forest, Veracruz, Mexico
(Instituto de Ecología, A.C, 2022)"Background and Aims: Droughts induced by climate change are expected to affect tropical cloud forests. As functional traits are useful indicators of plant species performance, this study aimed to determine the effect of ... -
Fenología, sincronía floral y éxito reproductivo de Neolloydia conoidea (Cactaceae)
(Sociedad Botánica de México, 2019)"Antecedentes: Los estudios sobre los patrones de floración, sincronía floral y éxito reproductivo en cactáceas son incipientes y de muchas especies se desconoce prácticamente su biología reproductiva como ocurre con ... -
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 ... -
Interaction between plants growing together from germination to 2 years: A test of competition and phylogenetic closeness for Northeastern Mexico
(Universidad de Concepción, 2022)"Competition and facilitation are important factors affecting seedling survival. These factors probably affect plant distribution and abundance. Interactions between species relate to phylogeny, in that closely related ... -
Mechanisms of fasting-mediated protection against renal injury and fibrosis development after ischemic acute kidney injury
(MDPI, 2019)"Ischemia-reperfusion injury of the kidney may lead to renal fibrosis through a combination of several mechanisms. We recently demonstrated that fasting protects the rat kidney against oxidative stress and mitochondrial ... -
Morphological differences of Turnera diffusa (Turneraceae) in two populations differing in rainfall at Northeastern Mexico
(Sociedad Botánica de México, 2019)Background. Plant morphology is the expression of a set of characteristics in response to environmental conditions and therefore to the availability of resources. Questions. Are the populations of Turnera diffusa ... -
Niche conservatism in a plant with long invasion history: the case of the Peruvian peppertree (Schinus molle, Anacardiaceae) in Mexico
(Meise Botanic GardenRoyal Botanical Society of Belgium, 2020)"Background and aim - Invasive plants should only colonize habitats meeting the environmental conditions included in their native niches. However, if they invade habitats with novel environmental conditions, this can induce ...
