Title cicada_final
Downloaded 28 times
Description Contains the data used in the final repeated-measures analyses. Data include the BBS route information (STATE, ROUTE, RTCODE, LAT, LONG), the number of years of data (NYEARS), whether the site includes data for all (cicada) years or not (EMALL), the type of cicada (13 or 17 year; TYPE) and brood number (BROOD), and the mean standardized bird data for each year vis-a-vis the cicada cycle from emergence - 4 (YM4) through year 12 after emergence (Y12) for sites within the range of 13-year broods or year 16 after emergence (Y16) for sites within the range of 17-year broods. Missing values are listed as -9.

Title bbs_cicada_data
Downloaded 29 times
Description This file contains the original BBS data for the 15 bird species used in the analyses along with the associated cicada brood data. Each line contains the following data: SPECIES (AOU number), STATE, ROUTE, OBSNUM {observer number), LATitude, LONGitude, YEAR, BIRDS (N birds observed), log-transformed N birds, N birds standardized to mean of 0 and SD=1, YRSFRMEM (years from the last emergence), TYPE (13-year or 17-year), BROOD number, NYEARS (of data for that site overall), EMEVENT (whether the data for that site includes an emergence year or not), EMALL (whether the data for that site includes values for all years of the relevant cicada cycle), XMASS (mass of the bird species).
