April Randle's research is broadly focused on how ecological factors shape the behavioral and morphological traits of species and influence species' distributions and interactions. She has conducted research on a range of taxa including: tropical trees (forest restoration), primates (foraging behavior), temperate flora (plant ecology, mating system evolution, plant-pollinator interactions), marine mammals (population size estimation of large cetaceans), tropical freshwater fish (adaptations to extreme environments), and amphibians (impacts of pesticides, toxicology).
Her most recent work focuses on ecological factors that influence the evolution of plant mating systems, and how the mating system can drive species diversification and influence species distribution.
