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.) ... -
Combined effect of water potential and temperature on seed germination and seedling development of cacti from a mesic Argentine ecosystem
(Elsevier, 2017)"Global climatic change will be associated with an increase of droughts and heat waves, which can affect seed germination and plant population dynamics. Cactus species from mesic ecosystems are likely to be more affected ... -
Effect of induced global warming on survival and performance of succulent species from Southern Chihuahuan Desert
(2016)"Numerous ecological studies have assessed the potential consequences of climate warming within several ecosystems worldwide. However, the impact of global warming on desert plants is still little studied. Most predictions ... -
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 %), ... -
Germinación de especies de cactáceas en categoría de riesgo del desierto chihuahuense
(Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias, 2011)"Se presenta una síntesis de los principales resultados sobre germinación de semillas de 28 cactáceas con estatus de conservación y cuatro sin estatus, nativas del desierto chihuahuense. Se incluye la información referente ... -
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, ... -
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 ... -
Induced climate change impairs photosynthetic performance in Echinocactus platyacanthus, an especially protected Mexican cactus species
(Elsevier, 2014)"The responses of desert plants to climate warming have been poorly assessed, perhaps due to the overall expectation that desert vegetation will expand as a consequence of this component of climate change. However, determining ... -
Relevancia funcional de los nectarios extraflorales de Cylindropuntia imbricata(Grifth) (Cactaceae).
(2013)"La presente investigación tiene como objetivo estudiar la anatomía de los nectarios extraflorales (NEF) de la Cactaceae Cylindropuntia imbricata, así como evaluar la influencia de la disponibilidad de agua y de la temperatura ... -
Seasonal ecophysiological variations of Echinocactus platyacanthus, a specially protected cactus species: Effect of induced climate warming
(Elsevier, 2021)"Cactus species are key components in American deserts and have a high socioeconomic value. Climate change exerts a threat to biodiversity, structure and functioning within deserts and many cactus species are predicted to ...
