Group size affects predation risk and foraging success in Pacific salmon at sea
… especially by improved predator avoidance and foraging efficiency. However, such theories are difficult to test in the wild, especially in marine environments where observing individuals is challenging, and quantifying predation risk or foraging success is often impossible. To overcome these …

Waggle Dance Your Own Way: Individuality, Network Structure, and an Herbicide Stressor in Recruitment, Foraging, and Neurobiology in the Honey Bee (Apis mellifera L.)
… structure, function, role in the regulation of collective foraging in the context of the hive as a super-organism, and even its utility as a study system for understanding sublethal behavioral effects of pesticide exposure. This dissertation presents three novel studies of the waggle dance. In …

Sociality in African mole-rats : exploring how rainfall affects dispersal and genetic exchange in the Natal mole-rat (Cryptomys hottentotus natalensis)
… group size, highlighting the benefits of collective foraging. But during winter body condition decreased with increasing group size, likely due to low quality of food and a necessity to continue foraging through winter. Interestingly, the body condition in reproductive females increased …
