Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

How vulnerable are amphibians to climate change? A mechanistic perspective

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Amphibians are frequently identified as highly vulnerable to climate change, yet the mechanisms driving this sensitivity remain uncertain. Approaches that explicitly link physiological mechanisms to environmental variation provide powerful tools for forecasting climate ...

Managing the development of nurse plant species to improve tree growth and soil fertility in Mediterranean areas [PDF]

, 2008
In the Mediterranean basin, overexploitation has lead to the loss of most primeval forests and an increase of the surface area covered by shrublands that represent stages of degradation of mature forests.

Distribución y conservación de especies amenazadas en Mesoamérica, Chocó y Andes tropicales

Revista Mexicana de Biodiversidad, 2011
En este estudio se modeló el nicho ecológico proyectado como distribución potencial de 313 especies amenazadas en Mesoamérica, Chocó y los Andes tropicales, según las listas de la UICN. De estas especies, 285 fueron plantas y 28 fueron vertebrados terrestres. La superposición de las distribuciones de las especies amenazadas cubrió prácticamente toda la

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

Forest type and leaf habit mediate thermal and drought tolerance across a tropical elevational gradient

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how local climate patterns select for thermal and drought tolerance traits is needed to predict differential responses to climate change across complex ecosystems.

EVALUACIÓN DE UNA PLANTACIÓN CON DOS ESPECIES TROPICALES CULTIVADAS EN DIFERENTES TIPOS DE ENVASES

Revista Mexicana de Ciencias Forestales, 2018
Para contrarrestar la deforestación en México se han impulsado las plantaciones forestales; sin embargo, sus índices de supervivencia son de 35%. El objetivo de la presente investigación fue evaluar en campo la supervivencia y crecimiento de árboles de Tabebuia rosea y Enterolobium cyclocarpum, propagados en contenedores de ...
