Big-bang reproduction is a semelparous strategy, favored when offspring survival is low. When each offspring has only a small chance of making it to adulthood, concentrating energy into a single, large reproductive event increases the chance that at least some offspring will survive. If survival is generally higher, investing in fewer offspring with more parental care across multiple events becomes more advantageous. Likewise, a long generation time makes a single massive reproductive effort less useful, since there are fewer opportunities to reproduce, shifting toward repeated, smaller bouts of reproduction.
