Journal of Animal Ecology, EarlyView.This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...

El efecto del aprendizaje en la dinámica evolutiva de la polinización por engaño
Revista IntegraciónEn este trabajo proponemos una función tipo gaussiana para modelar el aprendizaje de los polinizadores en un sistema de interacción planta-polinizador cuando las plantas recurren a la polinización por engaño, es decir, las plantas atraen a sus ...

Coinvasional disruptions to island pollinator networks
Conservation Biology, EarlyView.Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Synthesis of Pollinator‐Friendly Management in European Protected Areas
Conservation Biology, EarlyView.Effectiveness of pollinator‐friendly management in European protected areas. Abstract Pollinators are important to humans and nature due to their role in ecosystem functioning and services. Research on the effects of pollinator management in protected areas is insufficient compared with that on farmlands and urban areas, potentially hindering ...

New Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

RELEVAMIENTOS DE INSECTOS POTENCIALES POLINIZADORES DE TRÉBOL ROJO
Boletín de la Sociedad Zoológica del Uruguay, 2020 The reduction of pollinator populations globally generates a lot of concern about the impact it can have on the maintenance of ecosystems and cultivated species. In this work, the different insects that visited the red clover flowers, a forage legume with pollination problems in Uruguay, are reported, and their importance as pollinators is discussed.
