Repeated shifts out of tropical climates preceded by whole genome duplication. [PDF]

New Phytol
Summary While flowering plants have diversified in virtually every terrestrial clime, climate constrains the distribution of individual lineages. Overcoming climatic constraints may be associated with diverse evolutionary phenomena including whole genome duplication (WGD), gene‐tree conflict, and life‐history changes.

Environmental heterogeneity influences liana community differentiation across a Neotropical rainforest landscape. [PDF]

Ecol Evol
By analyzing liana community variation among land units (LUs) that differ in geomorphology and soil properties along a 640‐ha tropical rainforest landscape in a neotropical reserve, we found strong evidence supporting our hypothesis that environmental heterogeneity, as represented by discrete LUs, promotes differentiation in liana composition across ...

Pollination ecology in the tropical Andes: moving towards a cross-scale approach. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Vertically stratified frugivore community composition and interaction frequency in a liana fruiting across forest strata

Biotropica, Volume 55, Issue 3, Page 650-664, May 2023., 2023
Our findings suggest a continuous shift in the frugivore community composition along the vertical gradient of a plant species fruiting across forest strata, from a few generalized frugivores in the understorey to a diverse set of specialized frugivores in the canopy.

Comparative wood anatomy and origin of woodiness in subfamilies Secamonoideae and Asclepiadoideae (Apocynaceae)

TAXON, Volume 71, Issue 6, Page 1230-1250, December 2022., 2022
Abstract The Apocynaceae subfamilies Secamonoideae and Asclepiadoideae have undergone several transitions during their evolution with regard to growth form and degree of woodiness. In this study, we present a wood anatomical overview of both subfamilies that complements previous work on the remaining Apocynaceae.

Anthropogenic and environmental drivers shape diversity of naturalized plants across the Pacific

Diversity and Distributions, Volume 27, Issue 6, Page 1120-1133, June 2021., 2021
Abstract Aim The Pacific exhibits an exceptional number of naturalized plant species, but the drivers of this high diversity and the associated compositional patterns remain largely unknown. Here, we aim to (a) improve our understanding of introduction and establishment processes and (b) evaluate whether this information is sufficient to create ...
