Development of species distribution models helps identify source country anomalies in timber supply chains

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract For many timber species, a lack of consistent, comprehensive global distribution data makes validating supply source (country of harvest) difficult. To supplement these data, we developed species distribution models (SDMs) for the American mahogany species (genus Swietenia) to demonstrate how SDMs can assist in the analysis of supply sources ...

Flowering Asynchrony and Temporal Mate Restriction in Tropical Peat Swamp Forest Trees

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Tropical peat swamp forest trees flower asynchronously, restricting mating opportunities between conspecifics. Using an 18‐year dataset from Central Kalimantan, Indonesia, we show that while the same individual trees tend to flower together through time, there is enough turnover in which trees flower contemporaneously that lifetime mate restriction and
