Conserved and convergent mechanisms underlying performance-life-history trade-offs by Husak, Jerry F, Lailvaux, Simon P

“…Phenotypic trade-offs are inevitable in nature, but the mechanisms driving them are poorly understood. Movement and oxygen are essential to all animals, and as…”

How Do We Measure the Cost of Whole-Organism Performance Traits? by Husak, Jerry F., Lailvaux, Simon P.

“…Whole-organism performance traits, such as maximal speed and endurance capacity are undoubtedly costly, but we know little about how or when all of the costs…”

Exercise training reveals trade-offs between endurance performance and immune function, but does not influence growth, in juvenile lizards by Husak, Jerry F, Roy, Jordan C, Lovern, Matthew B

“…Acquired energetic resources allocated to a particular trait cannot then be re-allocated to a different trait. This often results in a trade-off between…”
