Dietary restriction (DR) is the most robust environmental manipulation known to increase
active and healthy lifespan in many species. Despite differences in the protocols and the …

Reduced reproduction is associated with increased fat storage and prolonged life span in
multiple organisms, but the underlying regulatory mechanisms remain poorly understood …

Life history theory seeks to explain the evolution of the major features of life cycles by
analyzing the ecological factors that shape age-specific schedules of growth, reproduction …

Summary 1 Resource acquisition and allocation are the physiological mechanisms
integrating foraging and life‐history traits. An understanding of the patterns of acquisition …

Immune function is likely to be a critical determinant of an organism's fitness, yet most
natural animal and plant populations exhibit tremendous genetic variation for immune traits …

While insect cold tolerance has been well studied, the vast majority of work has focused on
the effects of a single cold exposure. However, many abiotic environmental stresses …

A substantial number of Drosophila studies have investigated variation in desiccation and
starvation resistance, providing an opportunity to test for consistent patterns of direct and …

Laboratory studies on Drosophila have revealed that resistance to one environmental stress
often correlates with resistance to other stresses. There is also evidence on genetic …

Most animals face periods of food shortage and are thus expected to evolve adaptations
enhancing starvation resistance (SR). Most of our knowledge of the genetic and …

The regulation of energy homeostasis is fundamental to all organisms. The Drosophila fat
body serves as a repository for both triglycerides and glycogen, combining the energy …
