摘要:
Sexual selection theory predicts a trade-off between premating (ornaments and armaments) and postmating (testes and ejaculates) sexual traits

摘要:
ment in testes size depended on the number of individuals, while male investment in wings and antennae depended upon larval density. In contrast, the size of female

摘要:

摘要:
