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

Deciphering fire tolerance of #trees at the Amazonia–Cerrado transition by trait-based approach: Implications from species to communities
Wesley Jonatar Cruz, et al.

doi.org/10.1002/ajb2...
How do trees survive fire at the Amazon-Cerrado transition? This graphical abstract reveals how different strategies, like thicker bark, bud protection, and water use efficiency help species survive (or not) in fire-affected areas. The study findings show that fire not only selects the most resilient trees but also reshapes the entire community structure over time.

Moisture loss rate drives the species-specific sensitivity of shoot flammability to water status
By @azajmahmud.bsky.social , Nursema Aktepe, @schwilk.org ilk.org‬doi.org/10.1002/ajb2...52
Relationship between water status and shoot flammability. (A) The relationship between water potential and ignition delay time (s) across species (F1, 159 = 79.35, P < 0.001). (B) Relationship between LFMC and ignition delay time (s) across species (F1, 159 = 21.03, P < 0.001). (C) Relationship between water potential and heat release (kJ) across species (F1, 159 = 54.94, P < 0.001). (D) Relationship between LFMC and heat release (kJ) across species (F1, 159 = 105.1, P < 0.001). The lines indicate the trend of the response of ignition delay time (s) and heat release (kJ) to changing water status across species from the ANCOVA models.
