Aspects of differentiation between geographical populations of the harpacticoid copepodTigriopus fulvus

Aspetti del differenziamento tra popolazioni geografiche del copepode arpacticoideTigriopus fulvus

  • 20 Accesses


The results of crosses between Livorno and Trapani strains ofTigriopus fulvus show the presence of reproductive barriers between these populations. Tests to check the possibility of sexual attraction and recognition indicate that chemical signal difference and hence ethological divergence between these strains may also be arising.


I risultati di prove di incrocio tra ceppi di Livorno e Trapani diTigriopus fulvus mostrano la presenza di barriere riproduttive tra queste popolazioni. Esperimenti volti ad accertare la possibilità di attrazione e riconoscimento sessuale tra questi due ceppi indicano che in essi stanno comparendo delle differenze nei segnali chimici e quindi delle divergenze nel comportamento.
