ABSTRACT Aim The centropogonid clade comprising Burmeistera H.Karst. & Triana, Centropogon C.Presl and Siphocampylus Pohl stands out as one of the most rapid plant radiations in Neotropics. We investigated origin diversification to enhance our understanding fruit evolution other non‐floral traits genus. By exploring interplay morphological, ecological geographical factors, we sought provide new insights into how these elements have influenced evolutionary trajectory . Location Time Period Late Pliocene present. Taxon Triana (Lobelioideae: Campanulaceae). Methods Using Hyb‐Seq data from 329 nuclear loci, reconstructed a phylogenetic tree using maximum likelihood RAxML calibrated final with prior age estimates for Lobelioideae. Additionally, estimated species ASTRAL performed various comparative analyses explore historical biogeography across Results originated Western Cordillera Colombian Andes, dispersing rest Northern Andes Central America between Mid‐Pleistocene. Inflated fruits evolved multiple times genus, their distribution varying by region but reaching highest proportion eastern slopes Andes. Higher elevations larger sizes both increased diversification, especially late‐branching characterised inflated berries climbing habit, which underscores role driving diversification.

The role of phenotypic modularity in the evolution skull morphology birds has been a subject debate recent years. Furnariids (ovenbirds and woodcreepers), spectacular avian adaptive radiation, are distinguished their cranial as only passerines with two types kinesis, constituting great model to test whether novelties linked kinesis was associated shifts patterns evolutionary allometry skull. Our analyses by means geometric morphometric tools phylogenetic comparative methods show that beak neurocranium furnariids evolved modular fashion shaped evolution. Besides, species prokinesis higher degree morphological disparity, lower rates, well contribution than proximal rhynchokinesis, suggesting, observed several vertebrates, functional demands degrees promoted rapid integration throughout Prokinetic - robust morphotypes rhynchokinetic gracile morphotypes, have repeatedly convergence both modules, which suggests existence trade-offs long-standing optima related kinesis.
