Larus Audouinii

At the Ebro River delta colony in the western Mediterranean Sea, Audouin's gull, Larus audouinii, breeds in discrete aggregations called subcolonies, which showed strong differences in breeding parameters such as egg volume or breeding success. Egg parameters (such as size of both eggs and clutches) are strongly influenced by food availability. As all subcolonies are in the same area, differences in egg parameters might reflect different individuals' foraging efficiency. We measured mean clutch volumes in different subcolonies and chose those subcolonies that showed the greatest differences in this measure, which should indicate differences in parental body condition. Between these subcolonies we would expect, in turn, differences in offspring sex ratios. We took blood samples at hatching and fledging from chicks at these subcolonies and compared offspring sex ratios by means of molecular sexing. The proportions of young breeders differed between these subcolonies, and the subcolony with the greater proportion of young breeders produced smaller eggs and had lower breeding success. However, we did not detect any bias in progeny sex ratio, which probably indicates that if parental condition is not extremely reduced, selective pressures are insufficient to overcome the constraints imposed by Mendelian segregation of chromosomes.

Larus Audouinii

The possibility of persistent pollutants playing an adverse role in the reproductive success of Audouin's Gull in the western Mediterranean was examined through chemical analyses of 7 eggs of this species that did not hatch. Residues of organochlorine compounds and mercury were found.The conclusion has been reached that a further increase of present levels of DDE may well lead to a decline of the reproductive success of the species in the western Mediterranean, especially in the northern part. These observations, although limited, could have implications for further species as is already indicated by other work cited.

Podarcis Lilfordi

A survey of the helminth communities of Podarcis pityusensis (Boscá, 1883) and Podarcis lilfordi (Günther, 1874) (Sauria: Lacertidae) from the Pityusic and Gimnesic islands, respectively, in the Balearic Islands, Spain, was conducted. Both host species harbour similar though not identical helminth infracommunities. An analysis of the patterns of diversity for all helminths revealed that both lizards have depauperate isolationist infracommunities, possibly as a result of factors such as host ectothermy, the simplicity of their digestive canal, low vagility, and generalist feeding.
