Floral Integration and Phenotypic Selection on Floral Traits of <i>Ipomoea cavalcantei</i> (Convolvulaceae), a Rare, Endemic, and Endangered Species to the Amazon Ironstone Outcrops. [PDF]
Ecol EvolThis paper analyzed the evolutionary potential of Ipomoea cavalcantei (an endemic species from the Amazon) by using floral integration and phenotypic selection analysis. The analyzed population presented floral integration in style length, probably due to selective pressures from pollinators on floral traits related to pollen deposition.

Journal of Zoological Systematics and Evolutionary Research, Volume 59, Issue 1, Page 277-293, January 2021., 2021 We analyzed sequences from all species and most subspecies of Dendrocolaptes. We recovered the monophyly of Dendrocolaptes and that of most Dendrocolaptes species, except D. picumnus, which was paraphyletic to D. hoffmannsi. A coalescent‐based test supported 15 different evolutionary distinct lineages in Dendrocolaptes, indicating that the genus ...
