All-female salamanders engage in two biotic states: hybridism and reproductive parasitism. Hybrids should occupy areas transitional to those used by parental species, whereas parasites that engage in competition with… more

P. pediculata was the most abundant and widespread, yielding 1272 specimens out of 2211, and it was found in all provinces… more
