Bee diversity patterns in urban and adjacent natural ecosystems: high species turnover makes urban parks biodiversity refuges
Description
All these files enable to reproduce the results shown in the paper "Bee diversity patterns in urban and adjacent natural ecosystems: high species turnover makes urban parks biodiversity refuges" -metacom_early and metacom_late: bee metacommunities (presence/absence data) in the early and late season. -db_flowers: flowering species richness in each site and season (early and late). ecosystem type (urban vs natural) is indicated. -db_bees: nestedness contribution for each bee species in the early and late season. rank in the packed nested matrix is given, and whether the species is idiosyncratic or not is indicated. information on distribution (number of occurrences, i.e. sites occupied) and abundance (mean abundance where the bee is present) is also given. -db_sites: nestedness contribution for each site (ecosystem type -urban vs natural- is indicated) in the early and late season. rank in the packed nested matrix is given, and whether the site is idiosyncratic or not is indicated. -db_beta: pairwise betadiversity between sites in the early and the late season. type of betadiversity is indicated (nestedness, turnover, total) as well as type of site combination (uu: urban vs urban; nn: natural vs natural; nu: natural vs urban)

Steps to reproduce
We characterized bee communities in 7 urban parks and 3 natural areas scanning all the flowers and recording the presence and frequency of each bee species. Surveys took place once/month between March and October. Data analyses consisted in evaluatig diversity patterns in both ecosystems (alpha and betadiversity), as well as the nested structure of communities. We calculated idiosincrasy level of the species and relate this to distribution and abundance.
