... to investigate traits associated with starvation resistance. While control populations only live a few days without food, selection for starvation resistance results in populations that can survive weeks. We have previously shown that selection for starvation resistance results in increased sleep and reduced...

...Amanda K. Pettersen; Dustin J. Marshall; Craig R. White ABSTRACT Metabolic rate reflects an organism's capacity for growth, maintenance and reproduction, and is likely to be a target of selection. Physiologists have long sought to understand the causes and consequences of within-individual to among...

... will be heritable and maintained after sustained,multiple-generation exposure to hypoxic or hyperoxic atmospheres. We further propose that oxygen can influence the evolution of body size in fruit flies and can act as a limiting factor if flies are artificially selected for large body size. In one experiment, flies...

... intermittency has evolved in lines of house mice ( Mus domesticus ) that have been selectively bred for high voluntary wheel-running (wheel diameter 1.12 m) activity. After 23 generations, female mice from four replicate selection lines ran 2.7 times more revolutions per day than individuals from four random...

...Allen G. Gibbs ABSTRACT An increasingly popular experimental approach in comparative physiology is to study the evolution of physiological traits in the laboratory, using microbial, invertebrate and vertebrate models. Because selective conditions are well-defined, selected populations can...

...Adrienne E. Williams; Michael R. Rose; Timothy J. Bradley ABSTRACT We used laboratory natural selection on insects as a means of investigating the role of patterns of gas exchange in desiccation resistance. We used 15 populations of Drosophila melanogaster : five selected for desiccation resistance...
