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 ...
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 ...
Ecophysiological and anatomical mechanisms behind the nurse effect: which are more important? A multivariate approach for cactus seedlings
(2013-11)
"Background: Cacti establish mostly occurs under the canopy of nurse plants which provide a less stressful micro-environment, although mechanisms underlying this process are unknown. The impact of the combination of light ...
Strobilus and seed production of Dioon edule (Zamiaceae) in a population with low seedling density in San Luis Potosí, Mexico
(2013)
"We describe strobilus and seed development in a Dioon edule (chamal, palma, dameu') population characterized by low seedling and high adult tree density, in order to improve conservation decisions for this endangered cycad ...
Tolerance to cadmium of agave lechuguilla (agavaceae) seeds and seedlings from sites contaminated with heavy metals
(Hindawi, 2013)
"We investigated if seeds of Agave lechuguilla from contaminated sites with heavy metals were more tolerant to Cd ions than seeds from noncontaminated sites. Seeds from a highly contaminated site (Villa de la Paz) and from ...
Paths of water entry and structures involved in the breaking of seed dormancy of Lupinus
(Elsevier, 2016)
"Physical dormancy is the water impermeability of the seed coat caused by one or more palisade cell layer(s) called macrosclereids. The specialised structure for water entry sites is the water gap, which serves as a detector ...
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 ...
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 ...
Scientific literature on invasive alien species in a megadiverse country: advances and challenges in Mexico
(Pensoft Publishers, 2019)
"Interest in invasive species has increased around the world over the last several decades. In Mexico, studies on invasive species date as early as 1939 and the number of publications has increased considerably in recent ...
Dispersal of Dioon edule cycad seeds by rodents in a tropical oak forest in Mexico
(PAGEPress, 2021)
"Predation of seeds of the cycad Dioon edule Lindl. by Peromyscus mexicanus (Saussure, 1860) has been previously documented, demonstrating that the seeds’ toxins are not harmful when combined with a varied diet. However, ...
