C. elegans integrates food, stress, and hunger signals to coordinate motor activity
In the presence of a bacterial food source, the small nematode C. elegans greatly reduces its rate of locomotion. While mechanical agitation greatly stimulates the locomotion of well-fed animals on bacteria, it does not greatly stimulate the locomotion of food-deprived animals on bacteria. Thus, …

Evolutionary and proximate constraints on egg size in butterflies
… as well as the quantity and quality of available food during the larval and adult stage affect variation in reproductive traits to a high degree. In the butterfly B. anynana, larval and adult densities had surprisingly little effects on female reproduction, whereas dietary limitations yielded …

Some factors affecting the feeding ecology and socio-biology of the samango monkey, cercopithecus albogularis schwarzi roberts, 1931
… structure in an environment of apparently rich food supply, the food resources, feeding behaviour and ranging behaviour of the samango monkey was studied in forest on the Eastern Transvaal Escarpment. The taxonomy of the samango monkey in southern africa is discussed, as well as it•s …

Surviving Alpha: Using sequential analysis to examine the behaviours of Black-legged Kittiwake chicks during sibling pecking attacks
… Onset of this behaviour is attributable to food stress brought about by environmental conditions which impact parental foraging success within breeding seasons. Size differences between siblings, due to asynchronous hatching, allow alpha chicks to dominate parental feeds and pecking attacks …

The ontogeny of feeding behavior of Nicaraguan mantled howler monkeys (Alouatta palliata)
… their mothers’ milk during periods of seasonal food stress, and that juvenile mortality increases when tough resources are an important dietary component. To evaluate these predictions, I followed two groups of mantled howler monkeys—collecting behavioral data on juveniles, adult females, and …

Wild Civility: Cultivating the Foundations of Social Justice through Participation in a Wilderness Program
This heuristic inquiry examined if the foundations of social justice knowledge and beliefs were developed as a result of participation in a wilderness program and what knowledge and beliefs were developed. There were six participants in this study. Data collection involved participants completing …

Moult as a dynamic link in the annual cycle of birds: insights from seabirds and a long-distance migratory raptor
… strategies are influenced by differences in food availability or habitat quality. To explore these questions, I describe moult strategies in three seabird species (Cape Gannet Morus capensis, White-chinned Petrel Procellaria aequinoctialis and Whitecapped/Shy Albatrosses Thalassarche …
