Abstract We have studied some aspects of Besdolus ravizzarum biology in the Apennines. This stonefly has a very localized distribution in southeastern France and northern Italy. This species is considered threatened. For this reason it is especially relevant to improve knowledge about its natural history, previously unknown. Despite the large size of nymphs, this species shows a univoltine life cycle. The growth is slow but uniform from October to April or May when the short flight period occurs. The analysis of the gut contents indicates this species is a predator, feeding mainly on Baetidae and Chironomidae. It is notable that the development of this carnivorous species through cold periods coincides with the season with higher richness and density of potential prey in Apennine streams. Further studies are needed to improve knowledge of the distribution of the species and to start planning effective conservation efforts. 相似文献

Cichlid fishes of the East African Rift Valley lakes constitute an important model of adaptive radiation. Explosive speciation
in the Great Lakes, in some cases as recently as 12 400 years ago, generated large species flocks that have been the focus
of evolutionary studies for some time. The studies have, however, been hampered by the paucity of biochemical markers for
phylogenetic reconstruction. Here, we describe a set of markers which should help to alleviate this problem. They are the
class I genes of the major histocompatibility complex. We provide evidence for the existence of at least 17 class I loci in
cichlid fishes, and for extensive polymorphism of three of these loci. Since the polymorphism has a trans-species character,
it will be possible to use it in investigating the founding events of the individual species. The sequences of the cichlid
class I fishes support the monophyly of actinopterygian fish on the one hand, and of tetrapods on the other.
