According to the Evolution of Increased Competitive Ability (EICA) hypothesis and Enemy Release Hypothesis (ERH), comparing the plants from the same species, individuals from the invasive range will outperform those from the native range. However, not all recent...

Sex-role reversal, in which males care for offspring, can occur when mate competition is stronger between females than males. Secondary sex traits and mate attracting displays in sex-role-reversed species are usually more pronounced in females than in males. The...
