Niche analyses and the potential distribution of four invasive bumblebees worldwide [PDF]

open access: yesEcology and Evolution
The introduction of bees for agricultural production in distinct parts of the world and poor management have led to invasion processes that affect biodiversity, significantly impacting native species. Different Bombus species with invasive potential have

Pollination success increases with plant diversity in high-Andean communities [PDF]

open access: yesScientific Reports, 2021
Pollinator-mediated plant–plant interactions have traditionally been viewed within the competition paradigm. However, facilitation via pollinator sharing might be the rule rather than the exception in harsh environments.

Delayed differentiation of epidermal cells walls can underlie pedomorphosis in plants: the case of pedomorphic petals in the hummingbird-pollinated Caiophora hibiscifolia (Loasaceae, subfam. Loasoideae) species [PDF]

open access: yesEvoDevo, 2022
Background Understanding the relationship between macroevolutionary diversity and variation in organism development is an important goal of evolutionary biology.

Ecological convergence in phytochemistry and flower-insect visitor interactions along an Andean elevation gradient. [PDF]

open access: yesEcol Evol, 2023
In this study, we detected patterns of ecological convergence along elevation in floral volatiles as well as cost–benefit ratio in seed versus pollinated seeds. Our results suggest that these evolutionary patterns are the result of biotic and abiotic pressures.

3D pollination biology using micro-computed tomography and geometric morphometrics in Theobroma cacao. [PDF]

open access: yesAppl Plant Sci, 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Gene Flow and Vertical Stratification of Pollination in the Bat-Pollinated Liana <i>Marcgravia longifolia</i>. [PDF]

open access: yesEcol Evol
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

An elevational gradient in floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus in Peru. [PDF]

open access: yesEcol Evol, 2023
We analyzed floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus along a steep elevational gradient in Peru. Results show floral traits and pollinator assemblage variation along the elevational gradient. We examined our results considering two hypotheses: (1) local adaptation to different bee assemblages ...
