Meeting Abstract 55.8  Sunday, Jan. 5 15:15  Physiological Components of Chick Quality at a Critical Life History Transition CORNELL, A.E.*; WILLIAMS, T.D.; Simon Fraser University; Simon Fraser University acornell@sfu.ca In passerines, the immediate post-fledging stage is marked by high levels of mortality, making the developmental “milestone” from nestling to fledgling a critical life history transition. Although many […]

Meeting Abstract 55.1  Sunday, Jan. 5 13:30  Mosaic physiology from developmental stochasticity: an alternative to phenotypic plasticity WOODS, H. A.; Univ. of Montana art.woods@mso.umt.edu A key problem in organismal biology is to understand the origins of functional diversity. Modern biology proposes two general mechanisms. The first is developmental programs, by which single cells diversify into the organized […]
