Fruit Traits Reflect Adaptation to Dispersers Along a Tropical Elevational Gradient [PDF]

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates how fruit traits related to frugivore dispersal—specifically diameter, colour and presentation—vary along an elevation gradient in Papua New Guinea. Results showed that fruit diameter decreases with elevation, bird‐attracting colours are more common at higher elevations, and branch‐borne (ramiflorous) fruits increase with ...

Tropical psychotria plants are a rich source for peptide inhibitors of human prolyl oligopeptidase [PDF]

open access: yesNatural Products and Bioprospecting
Peptides from natural sources have often served as valuable leads in drug discovery. Plant-derived protease inhibitors are a notable class, yet their distribution, diversity, and targets remain underexplored. Here, eleven tropical Psychotria species were

Bract size affects resource availability and fruit set in a hummingbird‐pollinated plant with distyly polymorphism [PDF]

open access: yesPlant Biology, Volume 27, Issue 7, Page 1478-1487, December 2025.
In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The
