Titel:
Does testis size track expected mating success in yellow dung flies? 
Abstract:
1. We quantitatively compare the fitness function linking male mating success in the field to body size and the allometric relationship linking testis length (estimating sperm production) to body size, both empirically derived, for the yellow dung fly Scathophaga stercoraria (Diptera: Scathophagidae). 2. We find that both relationships are similarly non-linear (quadratic) and increasing. The most parsimonious interpretation of this congruence is that the evolution of testis size (and hence sperm...    »
