Animals have evolved a multitude of signaling pathways that enable them to orchestrate
diverse physiological processes to tightly regulate systemic homeostasis. This signaling is …

Metabolic cold adaptation, or Krogh's rule, is the controversial hypothesis that predicts a
monotonically negative relationship between metabolic rate and environmental temperature …

Previous studies have shown that selection for starvation resistance in Drosophila
melanogaster results in delayed eclosion and increased adult fat stores. It is assumed that …

Starvation causes the accumulation of lipid droplets in the liver, a somewhat counterintuitive
phenomenon that is nevertheless conserved from flies to humans. Much like fatty liver …

One of biology's most perplexing ideas is the biological control of an organism's size. Even if
many questions remain unanswered, it can be logically implied that the size of an individual …

Activity patterns tend to be highly stereotyped and critical for executing many different
behaviors including foraging, social interactions, and predator avoidance. Differences in the …

Background Drosophila melanogaster is a leading genetic model for studying the neural
regulation of sleep. Sleep is associated with changes in behavior and physiological state …

Thermal tolerance and preference are traits commonly considered when mass-producing
farmed animals as temperature impacts production. In this study, the impact of age and …

Interactions between sleep and feeding behaviors are critical for adaptive fitness. Diverse
species suppress sleep when food is scarce to increase the time spent foraging …

Food represents a limiting resource for the growth and developmental progression of many
animal species. As a consequence, competition over food, space, or other resources can …
