The influence of competition and nest site size on various life-history variables. (a) The correlation of distance to nearest conspecific colony with number of workers (squares, continuous line) and total production (diamonds, dashed line) in the Bavarian community. (b) The correlation of distance to nearest conspecific (diamonds, dashed line) and slavemaking colony (squares, continuous line) with colony per-capita productivity in the NY community. (c) The correlation of size of the nest site with workers (squares, continuous line) and total production (diamonds, dashed line) in the Bavarian community. (d) The correlation of nest site size with number of slaves (black squares, continuous line) and slavemaking workers (white squares, dashed line) in the Bavarian community, and of nest site size with number of slaves (grey diamonds, grey line) in the WV community. All variables are log transformed.
