Seed Thermal Response, and Morphological and Biochemical Plasticity in <i>Wigandia urens</i> as Indicators of Its Utility for Elevational and Latitudinal Assisted Migration. [PDF]

Ecol Evol
To identify the phenotypic plasticity in germination traits related to the tolerance to changes in temperature resulting from CC and improve the successful of plant cover recovery in elevational and latitudinal gradients, we assessed the amplitude and variability of phenotypic plasticity in the seed response of W.

Evaluación de métodos no paramétricos para la estimación de riqueza de especies de plantas leñosas en cafetales

Botan‪ical Sciences, 2006
Los cafetales, como parte del paisaje, contribuyen a la diversidad regional de especies leñosas. La riqueza de árboles fue evaluada en ocho fincas cafetaleras activas y abandonadas, y se comparó la riqueza observada o muestreada con la riqueza estimada ...
