Emergence of structure in plant-pollinator networks: Low floral resource constrains network specialisation

Specialisation enhances the efficiency of plant-pollinator networks through the exchange of conspecific pollen transfer for floral resources. Floral resources form the currency of plant-pollinator interactions, but the understanding of how floral resources affect the structure of plant-pollinator networks remains modest. Previous theory predicts that optimally foraging animal species will specialise to improve resource acquisition under high resource availability. Although floral resource availability depends on both the plant production and animal consumption of the resources, previous work has assumed that production and availability to be equivalent. This potentially may have led to erroneous inferences on the effect of resource availability on specialisation. We develop a mutualistic Lotka-Volterra consumer-resource model to investigate the influence of floral resource availability on plant-pollinator network structure. The model incorporates animal adaptive foraging behaviour, flor..., This data was simulated with theoretical model which reperesent plant-pollinator community. Parameter are generated abitrarily for each networks which correspond to each row in the spread sheet. Network structure and species' characteristics were estimated and stored for each network. The simulation was carried out with High Performing Computing. The simulations were conducted using R language., , # Yahaya, M.M., Rodger, J.G., Landi, P., Hui.
