Sexual selection and territory size in male cunners Tautogolabrus adspersus, in Conception Bay, Newfoundland
The occurrence of sexual selection was investigated in the cunner, Tautogolabrus adspersus (Walbaum), in Conception Bay, Newfoundland. Field observations show that the number of spawns was different between territorial males and, consequently, that sexual selection occurs among those males. Correlat...
