Examining variation in the leaf mass per area of dominant species across two contrasting tropical gradients in light of community assembly
(John Wiley and Sons Ltd, 2016-08)
Understanding variation in key functional traits across gradients in high diversity systems and the ecology of community changes along gradients in these systems is crucial in light of conservation and climate change. We ...
Heterochromatin variation in Oziroë argentinensis (Hyacinthaceae) revealed by florescent banding
(Univ Florence Botany Inst, 2006-01)
Previous studies in Oziroë argentinensis (Lillo et Hauman) Speta, have showed variation of heterochromatic regions between and within different populations of the species. In this study, were examined the heterochromatic ...
Geographic Variation in the Acoustic Signals of Dendropsophus nanus (Boulenger 1889) (Anura: Hylidae)
(2020-09-09)
Anurans communicate information during breeding activity to conspecifics mainly through acoustic signals, and different evolutionary forces may produce geographic variation in such communication systems. To understand which ...
