Evolution of Physiological Traits: Natural and Artificial Selection


Organizer:

Pawel Koteja (Jagiellonian Univ., Poland)
Marek Konarzewski (Univ. Bialystok, Poland)

Experimental evolution - experiments with artificial selection or laboratory natural selection - provide a straightforward and methodologically strong method of testing hypotheses concerning correlated evolution of complex morpho-physiological adaptations. The experiments can be used to find out how selection on a defined trait, or selection for an ability to cope with a defined environmental challenge, changes other traits of the organisms. The selected lines provide also a superb model to study biochemical and molecular mechanisms underlining adaptations observed at organismal level. The selection experiments, however, do not provide any information on whether the traits of interest are subject to natural selection. Such an information can be obtained only by studying free-living populations under natural conditions. Recently, modern molecular methods allowed also to get insights into selection processes in ancestors of extant species. However, because of tremendous complexity of natural environment and relations among individuals in the free-living populations, a research on natural selection on physiological traits can hardly provide results allowing strong inferences concerning causal factors. This symposium will provide a platform of communication for evolutionary physiologists and ecologists who approached the questions concerning evolution of physiological adaptations related to energy metabolism applying the two research lines.
