These datafiles contain the plant-pollinator interaction data collected by Paul CaraDonna et al. at the Rocky Mountain Biological Laboratory in Gothic, CO, USA during the 2013, 2014 and 2015 growing season. These data were collected to investigate temporal variation in plant-pollinator interactions; specifically, these data were collected in a manner to allow for the construction of weekly plant-pollinator interaction networks in order to investigate fine scale temporal variation in plant-pollinator interactions. The data represent extensive community-wide field observations of animal...

Datasets describe the frequency of visits observed for each pollinator-plant interaction. More info in Bartomeus et al 2008 Oecologia 155 : 761-770. The study involved pollinator surveys in 3 sites per study species. Pairs of invaded and uninvaded plots were samples in all sites. Sites were sampled every 2 weeks during the entire flowering period of both C. affine acinaciformis and O. stricta. Each plant species was sampled during 6 minutes. Each species was sampled for a total of 36...

Interaction networks are widely used as tools to understand plant–pollinator communities, and to examine potential threats to plant diversity and food security if the ecosystem service provided by pollinating animals declines. However, most networks to date are based on recording visits to flowers, rather than recording clearly defined effective pollination events. Here we provide the first networks that explicitly incorporate measures of pollinator effectiveness (PE) from pollen deposition on stigmas per visit, and pollinator importance (PI) as the product of...

Data analyzing if managed bees drive parasite spread and emergence in wild bees

Given widespread concerns over human-mediated bee declines in abundance and species richness, conservation efforts are increasingly focused on maintaining natural habitats to support bee diversity in otherwise resource-poor environments. However, natural habitat patches can vary in composition, impacting landscape-level heterogeneity and affecting plant-pollinator interactions. Plant-pollinator networks, especially those based on pollen loads, can provide valuable insight into mutualistic relationships, such as revealing the degree of pollination specialization in a community; yet, local and landscape drivers of these network indices remain...
