Impacts of Low‐Level Jets on Moisture Transport to the Pantanal, Brazil

open access: yesInternational Journal of Climatology, EarlyView.
The moisture transports from the tropics to the subtropics by the low‐level jets (LLJs) east of the Andes crossing the Pantanal region. Four LLJs, east of the Andes, were identified and selected with correspondent Lagrangian moisture transport. The LLJ moisture source regions contribute to Pantanal (~63.5%) and precipitation increased (~30%) during LLJ

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Clarifying nomenclatural uncertainties in Jupunba (Caesalpinioideae, Leguminosae)

open access: yesNordic Journal of Botany, EarlyView.
Molecular phylogenetic studies have prompted substantial revisions in the systematics of the former genus Abarema, resulting in the reinstatement of the genera Punjuba and Jupunba, and a re‐circumscription of Abarema. Despite these advances, some taxa still require nomenclatural adjustments to reflect monophyletic lineages.

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

open access: yesOikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.
