Testing the migration syndrome : Comparative fecundity of migratory and non-migratory nymphaline butterflies
Empirical studies have shown a positive relationship between migration and fecundity, suggesting a ‘migration syndrome’ that also includes delayed reproduction and an extended reproductive lifespan. At the same time, life history theory predicts that the cost of migration should result in lower fecundity because both traits draw from a common resource. We test whether migration is associated with
