Does allometry of a sexually selected ornamental trait vary with sexual selection intensity? A multi‐species test in damselflies

摘要: Ornaments may show hyperallometry in certain taxa, i.e. large individuals have proportionally larger ornaments than small ones. One hypothesis suggests that higher sexual selection intensity leads to steeper hyperallometric patterns. This study tested whether an ornamental trait subject both intra- and intersexual showed allometric slopes when solely intrasexual selection. The employed the sexually selected male wing pigmentation of 14 calopterygid species (damselflies) differ (intrasexual versus selection). Hyperallometry was not a uniform pattern species. Furthermore, did between intensities. The allometry traits is therefore highly variable even among related Other pressures – probably species-specific at local scale – acting on might explain diversity patterns.
