To determine if the different approaches would yield different projections regarding bee visitation rates, we made CCG 50014 number of comparisons to investigate the effects of landscape complexity and the potential to predict one high quality floral patch drawing bees away from nearby lower quality patches. First, to investigate if the models’ different treatment of foraging resulted in qualitatively different predictions regarding how bees distribute in the landscape, we compared how bees leaving from a single nest were distributed in contrasting synthetic landscapes. Second, to investigate if the models generate different predictions for bee distribution in real landscapes, we compared the two models’ predictions for three different real landscapes that varied in the amount of pollinator-friendly habitat and landscape complexity. Finally, to specifically investigate the consequences of the two approaches for predicting the effect of adding pollinator friendly habitat (hedgerow or flower strip, which provides nesting and/or flowering resources) on crop pollination, we applied the models to a new set of synthetic landscapes with and without a hedgerow adjacent to a crop field. For simplicity we consider the same species throughout the paper, described with its life history in Table 1.
