Etude comparée du comportement de cour de Triturus alpestris alpestris (Laurenti, 1768) et Triturus alpestris cyreni (Wolterstorff, 1932) : approche évolutive. ; A comparative study of courtship behaviour of Triturus alpestris alpestris (Laurenti, 1768) and Triturus alpestris cyreni (Wolterstorff, 1932) : an evolutionary perspective

The species concept in the animal world is very abstract. With diverse methods scientists try to place boundaries between species. But this is generally theoretical. Indeed species are in continuous evolution, located more regularly between two evolutionary categories than inside a well-defined one. In this study we are interested by the courtship of two allopatric subspecies of the Alpine newt, Triturus alpestris alpestris and T. a. cyreni. We investigate the behaviour of two closely related taxa, in experimental conditions, to display the basis of behaviour evolution and isolating mechanisms... Mehr ...
