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.

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.

Estimación del servicio de polinización en un cultivo de alfalfa (Medicago sativa L.) mediante la cuantificación de flores disparadas

open access: yesEcología Austral, 2022
La polinización biótica afecta de forma directa al rendimiento de la mayoría de especies vegetales cultivadas. Por eso es importante monitorear el estado del servicio de polinización en un lote; sin embargo, es raro que esto se lleve a cabo.
