Non-eusocial bees are understudied with respect to foraging strategies and decision making, such as flower preferences. Understanding whether...

... túngara frogs and fringe-lipped bats generally rely on acoustic mating signals to find male túngara frogs in a mating or foraging context, respectively. However, two additional cues (vocal sac inflation and water ripples) can enhance detection and choice behavior. To date, we do not know the natural...
