Biogeographic affiliation and centers of richness as predictors of elevational range‐size patterns for Malesian flora

open access: yesEcography, Volume 2024, Issue 5, May 2024.
Our goal was to interrogate the idea that “mountain passes are higher in the tropics” by investigating ecological and biogeographic drivers of elevational range‐sizes patterns among equatorial flora. We used herbarium records for 60 species‐rich plant families, representing 18 535 species total, to estimate distributions over a 4500 m elevational ...

The southern Brazilian tropical forest during the penultimate Pleistocene glaciation and its termination

open access: yesJournal of Quaternary Science, Volume 39, Issue 3, Page 373-385, April 2024.
ABSTRACT To describe the composition of the penultimate glacial Brazilian Atlantic forest, we analyzed pollen, charcoal and diatoms deposited in the section from 871 to 1400 cm of core CO14 drilled in the Colônia basin in southeastern Brazil. The landscape was characterized by a cool grassland with three conifer genera: Araucaria, Podocarpus and ...

A molecular phylogeny of scaly tree ferns (Cyatheaceae)

open access: yesAmerican Journal of Botany, 2007
Tree ferns recently were identified as the closest sister group to the hyperdiverse clade of ferns, the polypods. Although most of the 600 species of tree ferns are arborescent, the group encompasses a wide range of morphological variability, from diminutive members to the giant scaly tree ferns, Cyatheaceae.

Epiphytic biomass of a tropical montane forest varies with topography [PDF]

open access: yes, 2012
The spatial heterogeneity of tropical forest epiphytes has rarely been quantified in terms of biomass. In particular, the effect of topographic variation on epiphyte biomass is poorly known, although forests on ridges and ravines can differ drastically ...
