Edaphic effects on forest structure and tree species composition in three seasonally dry tropical forest types in Cambodia

open access: yesNordic Journal of Botany, EarlyView.
Soil conditions are critical factors shaping forest structure and tree species composition in seasonally dry tropical forests (SDTFs); however, few studies have evaluated edaphic effects in Cambodia's unique lowland forest landscape, where different forest types coexist under similar climatic conditions.

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.
