Clarifying nomenclatural uncertainties in Jupunba (Caesalpinioideae, Leguminosae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 5, May 2026.
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.

From flower buds to bolls: how cotton reproductive structures shape boll weevil development, reproduction and survival

open access: yesPest Management Science, Volume 82, Issue 5, Page 4576-4584, May 2026.
Female boll weevils feeding on flower buds promote reproduction regardless of their immature diet, whereas boll feeding increases lipid reserves and lifespan, revealing a nutrition‐driven trade‐off that sustains survival and reproduction in tropical boll weevil populations.

Soybean yield performance in oxisols with varying morphological and physicochemical characteristics

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soybean (Glycine max (L.) Merril) yield in tropical high‐altitude regions is strongly influenced by soil physical and chemical attributes, particularly in highly weathered oxisols, where variability among suborders may affect crop performance.
