Resumen

Antecedentes
Los trópicos del Nuevo Mundo han experimentado un paisaje dinámico a lo largo de la historia evolutiva y albergan una gran diversidad de flora y fauna. Mientras que existen algunos estudios que abordan la diversificación en vertebrados y plantas neotropicales, todavía hay una falta de conocimiento en artrópodos. Aquí examinamos los patrones de diversificación temporal y espacial en la familia de caballitos del diablo Polythoridae, que comprende siete géneros con un total de 58 especies distribuidas en gran parte de América Central y del Sur.
Resultados
Nuestra filogenia calibrada en el tiempo para 48 especies sugiere que esta familia irradió durante el Eoceno tardío (~ 33 Ma), diversificándose durante el Mioceno. Al igual que otros grupos neotropicales, el Ancestro Común Más Reciente (ACMR) de la mayoría de los géneros de Polythoridae tiene un origen primario en los Andes del Norte, aunque el ACMR de al menos un género puede haber aparecido en la cuenca del Amazonas. Nuestro reloj molecular sugiere correlaciones con algunos eventos geográficos importantes, y nuestro modelado biogeográfico (con BioGeoBEARS y RASP) encontró una influencia significativa de la formación de los sistemas de Pebas y Acre en la diversificación temprana de estos damiselas, aunque la evidencia de la influencia del surgimiento de las diferentes cordilleras andinas fue mixta. Las tasas de diversificación han sido uniformes en todos los géneros, excepto en uno -Polythore- en el que un aumento significativo a finales del Plioceno (~ 3 mya) puede haber sido influenciado por el reciente levantamiento andino.
Conclusión
Los modelos biogeográficos implementados aquí sugieren que los Sistemas de Pebas y Acre fueron eventos geológicos significativos asociados con la diversificación de esta familia de damiselas; mientras que la diversificación en el árbol muestra cierta correlación con los eventos de construcción de montañas, es posible que otros cambios abióticos y bióticos durante nuestro período de estudio hayan influido también en la diversificación. La alta tasa de diversificación observada en Polythore podría explicarse por el levantamiento tardío de los Andes del Norte. Sin embargo, es posible que otros factores intrínsecos, como la selección sexual y natural que actúa sobre los patrones de color, estén implicados en la diversificación de este género.

abstract = "Background: The New World Tropics has experienced a dynamic landscape across evolutionary history and harbors a high diversity of flora and fauna. While there are some studies addressing diversification in Neotropical vertebrates and plants, there is still a lack of knowledge in arthropods. Here we examine temporal and spatial diversification patterns in the damselfly family Polythoridae, which comprises seven genera with a total of 58 species distributed across much of Central and South America. Results: Our time-calibrated phylogeny for 48 species suggests that this family radiated during the late Eocene (~ 33 Ma), diversifying during the Miocene. As with other neotropical groups, the Most Recent Common Ancestor (MRCA) of most of the Polythoridae genera has a primary origin in the Northern Andes though the MRCA of at least one genus may have appeared in the Amazon Basin. Our molecular clock suggests correlations with some major geographical events, and our biogeographical modeling (with BioGeoBEARS and RASP) found a significant influence of the formation of the Pebas and Acre systems on the early diversification of these damselflies, though evidence for the influence of the rise of the different Andean ranges was mixed. Diversification rates have been uniform in all genera except one - Polythore - where a significant increase in the late Pliocene (~ 3 mya) may have been influenced by recent Andean uplift. Conclusion: The biogeographical models implemented here suggest that the Pebas and Acre Systems were significant geological events associated with the diversification of this damselfly family; while diversification in the tree shows some correlation with mountain building events, it is possible that other abiotic and biotic changes during our study period have influenced diversification as well. The high diversification rate observed in Polythore could be explained by the late uplift of the Northern Andes. However, it is possible that other intrinsic factors like sexual and natural selection acting on color patterns could be involved in the diversification of this genus. ",
