[The Simuliidae (Diptera, Nematocera) of Tunisia. II. Keys for the identification of species actually collected]. / Les Simuliidae (Diptera, Nématocera) de la Tunisie. II. Clés pour la reconnaissance des espèces actuellement recensées.

The authors give keys for the knowledge of species of Simuliidae (larval, pupal and adult stages). The collected samples represented 44 localities situated on the main tunisian hydrographic networks.

[Chemically induced ectropodia in the Lacerta viridis embryo and formation of styliform limbs in reptiles]. / Ectropodie par voie chimique chez l'embryon de Lacerta viridis et formation des membres styliformes chez les Reptiles.

Administered into the eggs of Lacerta virifis on days 10 and 11 of incubation (at 25 degrees C), Cytosine-arabinofuranoside induces ectropodia in embryos, with a high frequency, which may reach 66%. The resulting styliform limbs display a general structure similar to that of the limbs of several species of serpentiform Reptilia.
