S. Via ; A. Bouck ; S. Skillman | 2000Sympatric races of pea aphids on alfalfa and red clover are highly ecologically specialized and significantly reproductively isolated. Much of the restriction of gene how between the specialized populations is due to habitat choice behavior of t[...]article/chapitre/communication
M. Caillaud ; S. Via | 2000Not only is ecological specialization a defining feature of much of Earth's biological diversity, the evolution of specialization may also play a central role in generating diversity by facilitating speciation. To understand how ecological speci[...]article/chapitre/communication
D. Aguinpombo | 2002The limited importance ascribed to sympatric speciation processes via host race formation is partially due to the few cases of host races that have been reported among host populations. This work sheds light on the taxonomy of Alebra leafhoppers[...]article/chapitre/communication
M. Caillaud | 1999Host specialization plays a central role in the diversification of herbivorous insects and yet we know very little about the evolution of this trait. Populations of the pea aphid, Acyrthosiphon pisum (Harris), are specialized and locally adapted[...]article/chapitre/communication
