“…They found that incorporation of adaptive foraging into the dynamics of a pollination network increases network persistence and diversity of its constituent species. Moreover, Song and Fledman (2014) constructed a mathematical model that integrates individual adaptive foraging behaviour and population dynamics of a community consisting of two plant species and a pollinator species. They found that adaptive foraging at the individual level, complementing adaptive foraging at the species level, can enhance the coexistence of plant species through niche partitioning between conspecific pollinators.…”

Our planet is changing at paces never observed before. Species extinction is happening at faster rates than ever, greatly exceeding the five mass extinctions in the fossil record. Nevertheless, our lives are strongly based on services provided by ecosystems, thus the responses to global change of our natural heritage are of immediate concern. Understanding the relationship between complexity and stability of ecosystems is of key importance for the maintenance of the balance of human growth and the conservation of all the natural services that ecosystems provide. Mathematical network models can be used to simplify the vast complexity of the real world, to formally describe and investigate ecological phenomena, and to understand ecosystems propensity of returning to its functioning regime after a stress or a perturbation. The use of ecological-network models to study the relationship between complexity and stability of natural ecosystems is the focus of this review. The concept of ecological networks and their characteristics are first introduced, followed by central and occasionally contrasting definitions of complexity and stability. The literature on the relationship between complexity and stability in different types of models and in real ecosystems is then reviewed, highlighting the theoretical debate and the lack of consensual agreement. The summary of the importance of this line of research for the successful management and conservation of biodiversity and ecosystem services concludes the review.

“…The consequences of adaptive foraging of pollinators for plant coexistence were explored in the theoretical studies of Kunin & Iwasa [6] and Song & Feldman [9]. Both pairs of authors noted that adaptive foraging produces a disadvantage for rare plant species, because optimally foraging pollinators are predicted to ignore a rare resource.…”

“…The original model describes the foraging success of pollinators and the pollination success of plants in relation to pollinator behaviour as specialists or generalists, but not the resulting population dynamics. Song & Feldman [9] added population dynamics of plants and assumed that the ratio of pollinators to plants remains constant, since a higher density of flowers should attract more pollinators from the surroundings to the local patch. By contrast, in this study, I model a closed system in which both plant and pollinator population dynamics depend on their local interactions.…”

)) challenged this view by proposing a mechanism of diversity maintenance based on pollination niche partitioning. In this article, I investigate under which conditions the mechanism suggested by Pauw can promote plant coexistence, using a mathematical model of plant and pollinator population dynamics. Numerical simulations show that this mechanism is most effective when the costs of searching for flowers are low, pollinator populations are strongly limited by resources other than pollen and nectar, and plant -pollinator interactions are sufficiently specialized. I review the empirical literature on these three requirements, discuss additional factors that may be important for diversity maintenance through pollination niche partitioning, and provide recommendations on how to detect this coexistence mechanism in natural plant communities.

In pollen‐limited plant communities, the foraging behavior of pollinators might mediate coexistence and competitive exclusion of plant species by determining which plants receive conspecific pollen. A key question is whether realistic pollinator foraging behavior promotes coexistence or exclusion of plant species. We use a simulation model to understand how pollinator foraging behavior impacts the coexistence dynamics of pollen‐limited plants. To determine whether pollinators are likely to provide a biologically important coexistence mechanism, we compare our results to bee foraging data from the literature and from a novel experimental analysis. Model results indicate that strong specialization at the level of individual foraging paths is required to promote coexistence. However, few empirical studies have robustly quantified within‐bout specialization. Species‐level data suggest that foraging behavior is sufficient to permit pollinator‐mediated coexistence in species‐poor plant communities and possibly in diverse communities where congeneric plants co‐occur. Our experiments using bumblebees show that individual‐level specialization does exist, but not at levels sufficient to substantially impact coexistence dynamics. The literature on specialization within natural foraging paths suffers from key limitations, but overall suggests that pollinator‐mediated coexistence should be rare in diverse plant communities.
