Pollinators visit related plant species across 29 plant–pollinator networks
Understanding the evolution of specialization in host plant use by pollinators is often complicated by variability in the ecological context of specialization. Flowering communities offer their pollinators varying numbers and proportions of floral resources, and the uniformity observed in these floral resources is, to some degree, due to shared ancestry. Here, we find that pollinators visit rel...
متن کاملUnderstanding Linkage Rules in Plant-Pollinator Networks by Using Hierarchical Models That Incorporate Pollinator Detectability and Plant Traits
The analysis of mutualistic networks has become a central tool in answering theoretical and applied questions regarding our understanding of ecological processes. Significant gaps in knowledge do however need to be bridged in order to effectively and accurately be able to describe networks. Main concern are the incorporation of species level information, accounting for sampling limitations and ...
متن کاملConsequences of plant invasions on compartmentalization and species' roles in plant-pollinator networks.
Compartmentalization-the organization of ecological interaction networks into subsets of species that do not interact with other subsets (true compartments) or interact more frequently among themselves than with other species (modules)-has been identified as a key property for the functioning, stability and evolution of ecological communities. Invasions by entomophilous invasive plants may prof...
متن کاملImplicit Feedback Recommendation for Plant-pollinator Networks
Examining and evaluating complex ecological communites is a popular study area of significant ecological value. Mutualistic plant-pollinator networks are an especially important community because of the crucial role of pollinator in food production, yet much is still unkown about the underlying community structures of these networks, as well as their stability under enviornmental pertubation. W...
متن کاملRareness and specialization in plant-pollinator networks.
Most rare species appear to be specialists in plant-pollinator networks. This observation could result either from real ecological processes or from sampling artifacts. Several methods have been proposed to overcome these artifacts, but they have the limitation of being based on visitation data, causing interactions involving rare visitor species to remain undersampled. We propose the analysis ...
