Episode notes
Energy Trade-Offs Drive Life Decisions
- Life history trade-offs force organisms to allocate limited energy between competing tasks like immunity and reproduction.
- Overinvesting in one function reduces resources for the other, shaping survival and reproductive choices.
Night Fieldwork Reveals Sexy Danger
- Amy recounts collecting wild crickets at night and finding predators like spiders and scorpions near calling males.
- That field experience highlighted the risks males take by broadcasting loud mating calls.
Horsehair Worms Hijack Cricket Resources
- Horsehair worms infect crickets as cysts, grow massively inside hosts, and consume their fat reserves.
- These parasites can manipulate host behavior and take energy that crickets would otherwise invest in reproduction.
