Selection of flower color phenotype by contrasting #pollinator visual perception in a hybrid zone between two #Calceolaria species

New #AJB research by Alicia Sérsic, Marco Antonetti & Andrea Cocucci

doi.org/10.1002/ajb2... #botany #plantscience #pollination #evolution
Schematic of the methodology for the phenotypic analyses. Reflection: collection of reflectance spectra from three flower parts in 175 individuals. Pollinator perception: measuring predictor variables, values of reflectance spectra based on the stimulation of their photoreceptors. PC1 of the PCA of the stimulation data for all photoreceptors across the three flower parts according to each visual model. Brightness distance (BD) and color distances (CD) between flower parts. Pollination: phenotypic selection analyses combining different fitness variables, pollen grains deposited on the stigma or pollen tubes in the style attributed to pollination by either birds or bees, and predictor variables PC1, BD, and CD for each pollinator.

DNA #metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

New #AppsPlantSci research by Motta, Saranholi, De Godoy & Corrêa Côrtes

bsapubs.onlinelibrary.wiley.com/doi/full/10.... #botany #seeddispersal #PlantEcology #DNAmetabarcoding
Network of bird dropping samples and plants. Plants were identified using seed morphology (left) and metabarcoding (right). Colored nodes represent plants detected by both methods, while black nodes indicate plants detected by only one method. Dropping samples are shown as filled, half-filled, or empty, depending on the overlap between methods. Point positions indicate which method detected more plant taxa. Orange markers next to plant names highlight species with mostly dry, non-fleshy fruits that are not typically consumed by birds. Image credit: Carina Isabella Motta
