Annual cycles in the incidence of b chromosomes in the grasshopper Myrmeleotettix maculatus (acrididae: orthoptera).

abstract：:North Africa is now recognized as a major area for the emergence and dispersal of anatomically modern humans from at least 315 kya. The Mediterranean Basin is thus particularly suited to study the role of climate versus human-mediated changes on the evolutionary history of species. The Algerian mouse (Mus spretus Lata...
