Data for: Female foraging strategy co-evolve with sexual harassment intensity in the Trinidadian guppy

Sexual harassment is a widespread evolutionary outcome of sexual conflict over mating rates. Male harassment can impose costs on females, and females often change their behaviors to avoid unwanted attention. In Trinidadian guppies (Poecilia reticulata), females experience two potential sources of male harassment: coercive sneak mating behavior (more harmful, and common in high-predation populations) and courtship displays (less harmful, and common in low-predation populations). Here, we tested whether female foraging strategy co-evolves with decreasing levels of male harassment as guppies colonize low-predation environments. We set up outdoor stream mesocosms with ecologically naïve males and females from either a high- or a low-predation population in a 2x2 design and tested whether populations diverge in female response to male harassment. We found that low-predation males used more courtship and fewer sneak tactics than their natural high-predation ancestors. Male sneak behavior redu..., Data was collected on a physical datasheet, entered into an Excel file, and processed in R.
