Abstract

The mitochondrial cytochrome b gene was amplified by PCR and sequenced directly in 21 shearwaters and 14 gulls. Within the monophyletic herring gull complex which is closely related and of recent origin, the Mediterranean herring gull (L. cachinnans) appears to be genetically distinct, thus confirming our preliminary study (Wink et al., 1994). The genetic speciation ofP. puffinus andP. yelkouan (Wink et al., 1993b) was also corroborated. Within theCalonectris diomedea-complex, the existence of at least three different maternal lineages became obvious besides a genetic differentiation between the 2 subspeciesC. d. diomedea andC. d. borealis, a pair of maternal lines was found within theC. d. diomedea group. Since birds belonging to one of these 2 maternal lineages were found in 3 to 5 of the mediterranean populations, a dispersion of female shearwaters throughout the range is suggested.
