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

open access: yesEcol Evol
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 ...

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

open access: yesPlant Biol (Stuttg)
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
