Published: 11 November 2022
...Camille Mirmiran; Maia Fraser; Leonard Maler We analysed the trajectories of freely foraging Gymnotus sp. , a pulse type gymnotiform weakly electric fish, swimming in a dark arena. We compared the fish's initial behaviour as it learned the relative location of landmarks and food, to its behaviour...

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

In ecology, the process of search has been dominated by the field of optimal foraging theory, namely, the marginal value theorem ( Charnov, 1976 ; Schoener, 1971 ; Nonacs, 2001 ) and satisficing ( Carmel...

... 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...

Interestingly, olfaction-related genes [i.e. odorant...
