Father glue deposition and daughter preference. Least-squares mean probability of examining mates of father species over other (non-father) species (logit-transformed values shown) plotted against least-squares mean number of glue depositions by fathers. Symbols, limnetics (open), benthics (filled), heterospecific foster father (diamonds), conspecific foster father (circles) and biological father (triangles). Spearman rank correlation: r = 0.943, n = 6, p = 0.0048.
