ReadMe for P.R. Martin and F. Bonier, ms. Species interactions limit the occurrence of urban-adapted birds in cities This readme file describes the variables in the file subset.quant.data.for.analysis.csv that was used in a supplemental analysis in the above manuscript. The format is comma delimited (csv). The file corresponds to the R code analysis also archived with this file (see line 2344). This subset of the original data includes only data for species pairs for which quantitative dominance data was accessible and could be reanalyzed, or species pairs for which experimental data (song playback experiments) were used to ascertain dominance relationships (N=80 species pairs). For any further queries please contact: pm45@queensu.ca entry = numbered rows of data that correspond to the full dataset, sorted by the taxonomic order of species pairs [following Gill, F. & Donsker, D. IOC World Bird List (v 6.2), http://www.worldbirdnames.org/ (2016)], then continent, then country.city, then dominance. spp.pair.num = species pair number from the full dataset (N=142 species pairs), sorted by the taxonomic order of species pairs (Gill and Donsker 2016) animal = 'Genus_species' for each data row, following the taxonomy of Gill and Donsker (2016); used as a random factor in analyses that control for phylogeny tax.order = taxonomic order of the focal species in each row (following the taxonomy of Gill and Donsker 2016) tax.family = taxonomic family of the focal species in each row (following the taxonomy of Gill and Donsker 2016) genus.species = taxonomic Genus.species of the focal species in each row (following the taxonomy of Gill and Donsker 2016) dominance = the relative position of a species in a behavioural dominance hierarchy, relative to its closely-related focal congener; either 'dominant' or 'subordinate' sympatry = status of range overlap for the closely-related focal congeners (dominant and subordinate species) at the location of the focal city in that row; either 'allopatric' when ranges did not overlap, or 'sympatric' when ranges did overlap, at the location of the focal city breed.occur = the breeding occurrence of the focal species in the focal city, ranging from 0 (absent from urban habitats) to 3 (widespread breeder in urban habitats) breed.propensity.max = the propensity for each species pair to breed in urban habitat within cities (one value per focal dominant-subordinate species pair); calculated for each paired dominant and subordinate species as the maximum breeding occurrence within a species pair for each city, averaged across all focal cities that overlapped their breeding ranges mean.breed.occur = the propensity for each species pair to breed in urban habitat within cities (one value per focal dominant-subordinate species pair); calculated for each paired dominant and subordinate species as the mean breeding occurrence within a species pair for each city, averaged across all focal cities that overlapped their breeding ranges sd.breed.occur = the standard deviation of the mean.breed.occur continent = the continent that holds the focal city for each row ('Africa', 'Asia', 'Europe', 'North America', 'South America'); note that for the purposes of this study, Central America and the Caribbean were included within 'North America' and New Zealand was included within 'Australia' country.city = Country.City for the focal row latitude = the latitude of the focal city in decimal degrees; negative values denote the southern hemisphere longitude = the longitude of the focal city in decimal degrees; negative values denote the western hemisphere ave.temp = mean annual temperature (degrees C) for the location of the focal city; calculated as the average temperature across all 12 months NPP = annual net primary productivity (g carbon/square m/year) for the location of the focal city econ.develop = the level of economic development of the country of the focal city, as designated by the United Nations (World Urbanization Prospects: The 2014 Revision. United Nations, 2015); coded as: developing economies (3), economies in transition between developing and developed (2), and developed economies (1) population = the number of people reported as living in the focal city no.obs = the number of observers completing surveys for the focal city obs.ability = the average of the self-reported abilities (i.e. knowledge of the breeding birds of the focal city) across all observers that completed surveys for the focal city; individual values range from 1 (the observer knows the city's birds a little bit) to 5 (the observer knows the city's birds very well) spp.per.city = the number of species for each focal city for which we obtained breeding occurrence data used in our analysis symp.urban.spp.per.city = the number of species for each focal city for which we obtained breeding occurrence data that were used in our analysis, and that were both sympatric with the other member of their species pair, and had high propensities to breed in urban habitats within cities (above a value of 1.743 breakpoint) centroid.x = the area-weighted mean longitude of the breeding range of the focal species, recorded as decimal degrees; negative values denote the western hemisphere centroid.y = the area-weighted mean latitude of the breeding range of the focal species, recorded as decimal degrees; negative values denote the southern hemisphere centroid.continent = the continent holding the area-weighted mean latitude and longitude point for the species' breeding range (centroid.y, centroid.x); in cases where the centroid fell within an ocean, we recorded the geographically closest continent to the centroid city.vs.cent.cont = whether or not the focal city occurs within the same continent as the centroid.continent for the species range; recorded as 'inside' if the focal city and species' centroid share the same continent, and 'outside' if they do not continent.for.dom.data = the continent(s) from which behavioural dominance data were obtained for the focal species pair city.vs.cont.for.dom.data = whether or not the focal city occurs within the same continent as the continent.for.dom.data - the continent from where the dominance data were collected; recorded as 'same' if the focal city is in the same continent as where the dominance data were collected, and 'different' if the focal city and dominance data are from different continents
