... 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...

...Bianca F. Menezes; Judit Salces-Ortiz; Heloïse Muller; Nelly Burlet; Sonia Martinez; Marie Fablet; Cristina Vieira ABSTRACT Phenotypic variance is attributed to genetic and non-genetic factors, and only the former are presumed to be inherited and thus suitable for the action of selection. Although...

...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...
