Pollen dispersal by insects determines the patterns of reproductive encounters between plants with flowers that have spatially or temporally segregated sexes. Pollinators exhibit varied responses to environmental gradients, such as those in grassland-forest ecotones. Individual-based interaction networks are useful yet underexplored tools understand how interactions vary across these gradients. To test a ecotone gradient affects interactions, we studied pollination Butia odorata individuals, key palm tree species threatened South American grassland ecosystem. We assessed, through Structural Equation Models (SEMs), network metrics (specialization and modularity) pollinator richness abundance (total, peripheral, core) respond gradients habitat population structure ecotone. Networks more isolated palms showed greater specialization modularity. Pollinator was dependent on context role. The peripheral pollinators were negatively affected density. core positively cover, which, turn, associated density proximity forest. Our results suggest can modulate presence pollinators, while increased cover matrix promote diversity decreasing dominance species.

Numerous studies have explored the organization of pollination networks and factors influencing these interactions at various spatial temporal scales. Within networks, species vary in their significance influence on one another (i.e. interactive roles), understanding which determine this enables us to better comprehend interconnected relationships that drive resilience diversity ecosystems. Nevertheless, despite ectothermic nature bees potential impact social behaviour bee foraging patterns plants, amount theoretical empirical information available regarding how thermal tolerance limits sociality affect roles within remains relatively scarce. In study, we assess physiological (thermal tolerance) traits shape role a network coastal environment Gulf Mexico, Mexico. For sociality, classified as eusocial, subsocial, solitary while for tolerance, used both warmest critical maximum, CT max ) coldest minimum, m temperature. general, found bees' explain studied. Specifically, eusocial had greater than subsocial bees. Moreover, observed with lower ax higher less heat cold tolerant) role. Our findings suggest inherent life history are valuable predicting may implications ecological, functional evolutionary processes ecosystems, including impacts resulting from climate change.
