...Megan Elizabeth Deeter; Lucy A. Snyder; Charlotte Meador; Vanessa Corby-Harris ABSTRACT Honey bee abdominal lipids decline with age, a change thought to be associated with the onset of foraging behavior. Stressors, such as pesticides, may accelerate this decline by mobilizing internal lipid...

...Camille Mirmiran; Maia Fraser; Leonard Maler ABSTRACT We analyzed the trajectories of freely foraging Gymnotus sp., a pulse-type gymnotiform weakly electric fish, swimming in a dark arena. For each fish, we compared the its initial behavior as it learned the relative location of landmarks and food...

... pollinators. Research into bee behaviour and foraging decisions has typically centred on managed eusocial bee species, including Apis mellifera and Bombus terrestris . 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...

... to consume relatively less L, which could be linked to low carotenoid absorption and transport as well as poor signal coloration. Sex-specific macronutrient foraging strategies have been previously observed in free-ranging birds ( Machovsky-Capuska et al., 2016b ). In our study, females in the MN group...

... delayed matching-to-sample tasks. Honey bees potentially process temporal signals during foraging activities, but the extent to which they can use such information is unclear. Here, we investigated whether free-flying honey bees could use either illumination colour or illumination duration as potential...

...Rikesh Jain; Axel Brockmann ABSTRACT We performed an RNA-seq-based comparison of gene expression levels in the antennae of honey bee drones and time-trained foragers (workers) collected at different times of the day and different activity states. Interestingly, olfaction-related genes [i.e. odorant...

... the outward journey, but not as effective when facing in the opposite direction on the homeward journey. We further showed that foraging routes improved through individual experience over multiple trips but not through the social transfer of route information via tandem running. We discuss our findings...

However, novel approaches that allocate video time to target prey capture events is required to obtain diet information for species that make long foraging trips over great distances. We...

Responses to tomato were consistent with this plant being a stressor for T . urticae , including reduced fecundity and reduced...

Hawaiian monk seals are opportunistic marine predators and their ability to adapt their feeding strategy and behavior to specific foraging...

However, other topics like foraging behaviour, social interactions or environmental acoustics can now be addressed as well and offer...

Using playback experiments at natural roosts, we tested whether two bat species, differing in their hunting strategies and foraging habitats, use rain noise...

Specifically, we found a negative relationship between exploratory behavior and the expression of the foraging ( Lhfor ) gene. Finally, we determine how colonies allocate exploratory individuals in natural conditions...

...Olivier Bles; Jean-Louis Deneubourg; Stamatios C. Nicolis ABSTRACT Insect societies are often composed of many individuals, achieving collective decisions that depend on environmental and colonial characteristics. For example, ants are able to focus their foraging effort on the most rewarding food...
