Pollinators are an important part of global biodiversity, providing essential ecosystem services to both crops and wild plants. Increasing evidence show that both wild and domesticated pollinators, as well as the plants that rely upon them, are currently declining around the globe (especially Europe and North America) (Potts et al. 2010, Lever et al. 2014). Habitat destruction, parasites, diseases as well as increasing use of pesticides have been linked to this increase in mortality among pollinating insects (Lever et al 2014). The decline of pollinating insects is of increasing concern as a widespread decline will have a negative effect on the wild plant diversity, the wider ecosystem stability, the crop production, as well as human welfare (Potts et al. 2010). Insects, and especially bees, are the main pollinators of most flowering plant species, and a decline in diversity among pollinators and their abundance would presumably bring with it a decline in pollination services for wild plant communities, potentially affecting communities of animal pollinated plants, and thus further reducing floral resources for the pollinators (Potts et al. 2010, Lever et al. 2014).Mutualistic networks, such as those made out of the interactions between plants and their pollinators, are known to display a high degree of nestedness with specialist plants usually being visited by generalist pollinators and specialist pollinators usually having generalist plant hosts (Lever et al. 2014, Petanidou et al. 2008).In a worst-case scenario, the decline of certain pollinators is predicted to trigger cascades of linked declines among the multiple plant species to which they are linked, which would seem to be especially true for generalist pollinators (Pauw 2007). Previous studies such as the study by Memmott et al. (2004) have previously tried to simulate the effect of the removal of pollinators. They showed that a random removal of pollinators resulted in a steadily increasing decline in plant species richness, with most of the plant extinctions occurring suddenly after 70–80% of all pollinators had been removed. A systematic removal beginning with the most specialized pollinators yielded and even slower loss of plant species richness until almost all pollinators had perished, at which point plant species numbers dropped suddenly to zero. Lastly, a systematic loss beginning with generalist pollinators showed a more rapid cumulative loss of plant species and the extinction functions for plants were essentially linear in this case, rather than dropping suddenly in one or more large steps.This study will aim test the results of Memmott et al (2004), whether there is a correlation between network functionality and pollinating insect species richness, and if that is the case whether or not there is a species richness threshold below which the network function collapses into low diversity.
