The male then entices a female to enter the nest and deposit her eggs for him to fertilize. The male stickleback makes the nest with pieces of plant material glued to an underwater plant stem with special cement secreted from his kidneys. He lures the female into his nest and convinces her to lay her eggs there – then he takes care of everything else. For example, he fans a current of water through the nest over the incubating eggs.

This selection on nest depth means that variance in fitness changed predictably across microhabitats, altering the opportunity for sexual selection to act on other traits. Previous studies have shown plasticity in stickleback nest construction in response to changing flow regimes. In an earlier experimental study, river‐caught males were exposed to rapid switches in flow conditions and allowed to construct nests under both flowing‐ and still‐water regimes within 7 days (Rushbrook et al. 2010). The nest site characteristics of the freshwater three‐spined stickleback, Gasterosteus aculeatus (form leiurus), were quantitatively investigated in springs and the main stream of the Yamayoke and the Tsuya River system, central Japan. Most nests (93·4%) were on a muddy or sandy substratum, at depths of 10–40 cm (84·3%), in water velocities less than 15 cm s−1 (76·2%) and in the 2020-05-11 Indeed, nest depth was a much stronger predictor of male mating success than more commonly studied targets of sexual selection in stickleback (size, condition, shape, color, infection status).
