Genetic and ecological data on the Anisakis simplex complex, with evidence for a new species (Nematoda, Ascaridoidea, Anisakidae).
A new distinct gene pool was detected, showing different alleles with respect to A. simplex sensu stricto and Anisakis pegreffii, widely extending the geographic ranges and the number of hosts of these 2 species.
Allozyme diversity of European freshwater crayfish of the genus Austropotamobius
The genetic erosion observed in Austropotamobius populations stresses the need to restore their genetic variability, e.g. by controlled restocking, for successful programs of recovery and management of these endangered crayfish.

Genetic markers in the study of Anisakis typica (Diesing, 1860): larval identification and genetic relationships with other species of Anisakis Dujardin, 1845 (Nematoda: Anisakidae)
The present findings represent the first established records of intermediate/paratenic hosts of Anisakis typica and extend its range to Somali waters of the Indian Ocean and to the Eastern Mediterranean Sea.
Genetic variation and natural hybridization betweenOrchis laxiflora andOrchis palustris (Orchidaceae)
The data indicate that hybrids are only partially fertile, with a very limited mixing up of the two parental gene pools; this is shown by the lack of significant lowering of genetic distances when sympatric and allopatric heterospecific samples are compared.
Molecular Taxonomy of European Plethodontid Salamanders (Genus Hydromantes)
Data from two contact zones in Italy indicate that taxa showing comparable levels of genetic differentiation have not reached the same level of reproductive isolation, and attempts are made to explain their genetic relationships.
Hybrid zones between two genetically differentiated forms of the pond frog Rana lessonae in southern Italy
Two distinct population groups of the pond frog Rana lessonae were detected in peninsular Italy and Sicily by multilocus electrophoresis, and the wide hybrid zone, diversity of genotypes and the agreement with Hardy‐Weinberg expectations suggest complete hybrid fertility.
