Adaptive dynamics and evolutionary branching: Theory and applications


  • Pietro Landi


Adaptive В Dynamics (AD) is a mathematical framework for the study of phenotypic evolution driven by selection in the ecological context [1,2,3]. Its mainВ innovative feature is the formalization of evolutionary branching, that is, theВ sympatric divergence of two morphs under disruptive selection from a singleВ phenotype. Subsequent evolutionary branching events are thus responsible forВ the increase of polymorphism in the community and, possibly, sympatric speciation.

The mathematical conditions for evolutionary branching were introduced inВ the late Nineties [4,5], but the formalization of critical branching events hasВ only recently been developed [6,7]. Moreover, such critical condition triggeringВ evolutionary branching has been systematically used to study the evolution ofВ polymorphism in prey-predator communities [8], in bioeconomic models of fisheries [9], and social systems [10,11]. Current work is addressing the emergenceВ of sympatric diversity in life-history strategies and its role in the emergenceВ of intransitive competitive interactions, as well as the concurrent evolution ofВ dispersal and self-fertilization in plant communities.
