Ecomorphology and history of a recurrent evolutionary adaptation to long-distance bird dispersal in Asteraceae
Background and aims: Genera of Asteraceae, belonging to different tribes, present a repeated pattern of morphological adaptations to epiornithochory and have unique distributions (widely disjunct and/or inhabit remote islands). This pattern requires the interplay between plant morphology and environ...

Background and aims: Genera of Asteraceae, belonging to different tribes, present a repeated pattern of morphological adaptations to epiornithochory and have unique distributions (widely disjunct and/or inhabit remote islands). This pattern requires the interplay between plant morphology and environmental aspects (ecomorphology), and between morphology and the evolutionary history (homology, homoplasy, and phylogeny). Adenostemma and Adenocaulon are investigated to: 1) establish some aspects of morphological and histochemical similarity in their diaspores, and associate that similarity to long-distance dispersal by birds, 2) superimpose these similarities in the phylogenetic tree of Asteraceae to determine whether they are homologous or homoplastic.
M&M: Previous work on Adenostemma and Adenocaulon is reviewed for analyzing their diaspores morphology and histochemistry, geographic distribution, and mode of dispersion. One of the current molecular-based phylogenetic trees of Asteraceae is employed as a template to perform evolutionary inferences. The criteria for distinguishing homology from homoplasy, and parallelism from convergence are applied.
Results: Adenostemma and Adenocaulon are located in the recently radiated crown (tribe Eupatorieae) and in one of the earliest diverging branches (tribe Mutisieae) of the Asteraceae tree, respectively. The set of features shared by both genera in relation to epiornithochory is homoplastic: two parallelisms, one reversion and one functional convergence.
Conclusions: A set of diaspore characters optimal for successful external dispersion (compatible with the ‘Dispersal Syndrome hypothesis’) evolved as homoplasies in several genera of the same family. Similar environmental pressures are expected to elicit similar adaptive morphologies, suggesting that morphological and histochemical homoplasy is often a consequence of natural selection.

Introducción y Objetivos: Géneros de Asteraceae de diferentes tribus presentan un patrón repetido de adaptaciones morfológicas a la epiornitocoria y tienen distribuciones únicas (ampliamente disyuntas y/o habitan islas remotas). Este patrón requiere la interacción entre la morfología de las plantas y el ambiente (ecomorfología), y entre la morfología y la historia evolutiva (homología, homoplasia y filogenia). Adenostemma y Adenocaulon se investigan para: 1) establecer algunos aspectos de similitud morfológica e histoquímica en sus diásporas y asociar esa similitud con la dispersión a larga distancia por aves. 2) superponer estas similitudes en el árbol filogenético de Asteraceae para determinar si son homologías u homoplasias. M&M: Se revisan trabajos sobre Adenostemma y Adenocaulon para analizar la morfología e histoquímica de sus diásporas, distribución geográfica y modo de dispersión. Se emplea un árbol filogenético molecular actual de Asteraceae como base para realizar inferencias evolutivas. Se aplican criterios para distinguir homología de homoplasia, y paralelismo de convergencia. Resultados: Adenostemma y Adenocaulon constituyen un linaje corona que ha experimentado radiación reciente (tribu Eupatorieae) y un linaje tempranamente divergente (tribu Mutisieae) en el árbol de Asteraceae, respectivamente. El conjunto de características que comparten ambos géneros en relación con la epiornitocoria es homoplásico: dos paralelismos, una reversión y una convergencia funcional. Conclusiones: Un conjunto de caracteres de las diásporas óptimos para una dispersión externa (‘Hipótesis del Síndrome de Dispersión’) evolucionó como homoplasias en varios géneros de la misma familia. Presiones ambientales similares provocarían morfologías adaptativas coincidentes, sugiriendo que estas homoplasias son consecuencia de la selección natural.
