Osmoxylon‐like fossils from early Eocene South America: West Gondwana–Malesia connections in Araliaceae

open access: yesAmerican Journal of Botany, Volume 112, Issue 6, June 2025.
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Insights From a New 1‐ha Permanent Forest Plot Reveal Differences Between Habitat Type and Similarities Between Forest Type in the Southwestern Amazon

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
Southwestern Amazon forests are highly diverse, but information on how tree diversity and composition changes between habitat and forest types remains scarce. We conducted floristic analyses to investigate these changes across a precipitation gradient, between habitat types, and between disturbed and old‐growth forest.

Nitrogen and Phosphorus Allocation Strategies in a Chronosequence of Tropical Dry Forests: Plant Coordination and Environmental Drivers

open access: yesBiotropica, Volume 57, Issue 2, March 2025.
We explored the allocation strategies of N and P in leaves and fine roots (metabolic organs) and, in stems and coarse roots (woody organs) of nine dominant tree species in secondary tropical dry forests using scaling analysis. The scaling relationships of P versus N concentrations in non‐leaf organs were isometric across secondary succession and ...
