SPRINGERBRIEFS IN EVOLUTIONARY BIOLOGY ROBUST...

Among the unresolved topics in evolutionary biology and behavioral ecology are the origins 
mechanisms  evolution  and consequences of developmental and phenotypic diversity. In an
attempt to address these challenges  plasticity has been investigated empirically and
theoretically at all levels of biological organization-from biochemical to whole organism and
beyond to the population  community  and ecosystem levels. Less commonly explored are
constraints (e.g.  ecological)  costs (e.g.  increased response error)  perturbations (e.g. 
alterations in selection intensity)  and stressors (e.g.  resource limitation) influencing not
only selective values of heritable phenotypic components but  also  decisions and choices (not
necessarily conscious ones) available to individuals in populations. Treating extant mammals 
the primary purpose of the proposed work is to provide new perspectives on common themes in the
literature on robustness (functional diversity  differential resistance to deconstraint of
conserved elements) and weak robustness (the potential to restrict plasticity and evolvability)
plasticity (variation expressed throughout the lifetimes of individuals in a population setting
evolvability potential)  and evolvability (non-lethal phenotypic novelties induced by
endogenous and or exogenous stimuli). The proposed project will place particular emphasis upon
the adaptive complex in relation to endogenous (e.g.  genomes  neurophysiology) and exogenous
(abiotic and biotic  including social environments) organismal features discussed as regulatory
and environmental perturbations with the potential to induce  and  often  constrain variability
and novelty of form and function
