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.

Moreover, effects landscape urbanization changes in floral nesting resource availability network structure with both cultivated wild plants have been poorly studied.

Abstract Determining how and why organisms interact is fundamental to understanding ecosystem responses future environmental change. To assess the impact on plant‐pollinator interactions, recent studies have examined effects of change individual interactions accumulate generate species‐level responses. Here, we review developments in using networks interacting individuals along with their functional traits, where are nested within species nodes. We highlight these individual‐level, trait‐based connect intraspecific trait variation (as frequency distributions multiple traits) dynamic communities. This approach can better explain interaction plasticity, changes probabilities network structure over spatiotemporal or other gradients. argue that only through appreciating such plasticity accurately forecast potential vulnerability follow this general guidance collect analyse high‐resolution data, hope improving predictions for targeted effective conservation.

Abstract Coextinctions may exacerbate the current biodiversity crisis. Yet, we do not understand all factors that shape robustness of communities to loss species. Here analyze how coevolution influences secondary extinctions mutualistic and exploitative communities. We find increases in mutualism but reduces it under interactions. These differences are due altering density interactions Coevolution leads densely connected sparsely magnitude these effects depends on strength size community.
