The Auk. This is a variable description of the following files: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Filename: NDVI_data_for_spring.txt Data of spring characterization through NDVI data for each year and land cover category (CORINE 2012 codes). Original and factor variables after the PCA are included. * year = year of the model * CLC.12.Corine = land cover category following CORINE 2012 codes ("211"= non-irrigated arable land, "221"=vineyards, "311"=broad-leaved forest,"321"=natural grasslands,"323"=sclerophyllous vegetation) * n.grids = number of grids included in the gam analyses * n.data = number of data included in the gam analyses * Deviance.exp = deviance explained by the gam model adjusting NDVI data * Day.SS = start of the season (julian day) * Day.end.SS = end of the season (julian day) * Day.max.NDVI = date of maximum productivity (julian day) * Speed.Greenup = spring green-up slope (NDVI units / day) * Speed.Green.down = spring green-down (NDVI units / day) * Max.NDVI = maximum level of NDVI (NDVI units) * NDVI.Day.SS = NDVI level at the start of spring (NDVI units) * NDVI.Day.end.SS = NDVI level at the end of spring (NDVI units) * PC1.Sp.Earl = Spring earliness. It is the factor 1 of a principal component analyses including the following variables (Day.SS, Day.end.SS, Day.max.NDVI, Speed.Greenup, Speed.Green.down) * PC2.Rate.Sp.Adv = Rate of spring advancement. It is the factor 2 of a principal component analyses including the following variables (Day.SS, Day.end.SS, Day.max.NDVI, Speed.Greenup, Speed.Green.down) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Filename = Summer_data.txt Data for each year of summer characterization using temperature and humidity data extracted with a R package RNCEP from the National Centers for Environmental Prediction. Original and factor variables after the PCA are included. * year = year * Tra.Deviance.exp = deviance explained by the gam model with temperature data * Day.max.Tr = day of maximum temperature (julian day) * Max.Tr = maximum temperature reach this year (º c) * Speed.rise.Tr = speed to reach maximum temperature (ºc/day) * Hdad.Deviance.exp = deviance explained by the gam model with humidity data * Day.Min.Hd = day of minimum humidity (julian day) * Min.Hd = minimum humidity (%) * Speed.min.hd = speed to reach minimum humidity (%/day) * PC1.Int.sum.dr = intensity of the summer drought. It is the factor 1 of a principal component analyses including the following variables (Day.max.Tr, Max.Tr, Speed.rise.Tr, Day.Min.Hd, Min.Hd, Speed.min.hd) * PC2.sum.earl = summer earliness. It is the factor 2 of a principal component analyses including the following variables (Day.max.Tr, Max.Tr, Speed.rise.Tr, Day.Min.Hd, Min.Hd, Speed.min.hd) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Filename: Individual_data.txt * ID = individual code * Site = "LM" for Las Minas or "PR" for Presa del Rey * Year = year of capture for this data * Date.min = date of first capture of the bird throughout the year (julian day) * Date.min.st = standardized date calculated within years and separating hatch year birds from other age classes * Age = age of the individual at capture ("HY"= hatch year; "SY" = second year; "ASY" = after second year; "AHY" = after hatch year) * Wing.Avg = average wing length within the year (mm) * Tarsus.Avg = average tarsus length within the year (mm) * Fraction = (Analysis of phenotype-dependent recruitment) "Survival" for recruitments or second year individuals and "Born" for hatch year individuals * Cycle = (Analysis of phenotype-dependent recruitment) Hatch year * Com.Cyc = (Analysis of phenotype-dependent recruitment) "1" complete cycle with data with born and survival individual "0" uncomplete cycle * Size = structural body size (individual PC1 scores of a principal component analysis of wing and tarsus length) * MFA = morphology of the flight apparatus (individual PC2 scores of a principal component analysis of wing and tarsus length) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Filename: Ind_ch_RMark.txt * ID = individual code * ch = individual capture history * n = individual frequency of captures * Site = LM (Las Minas) or PR (Presa del Rey) * MFAst = morphology of the flight apparatus standardized within each age category * Age.min = age at first capture ("HY"= hatch year; "SY" = second year; "ASY" = after second year; "AHY" = after hatch year) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Note: We have used "NA" when data were not available.
