Controllo genetico della fosfoesosoisomerasi (Phi) in Tisbe clodiensis (Copepoda, Harpacticoida)

Paolo M. Bisol;  Vittorio Varotto;  Bruno Battaglia — 1976

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

A method is described which permits the application of electrophoretic techniques for the study of enzyme polymorphisms to single individuals of the Copepod Tisbe. The method has been tested with F and, occasionally, F individuals obtained by crossings between two geographic populations of T. clodiensis. The electrophoretic analysis carried out for the Phi, shows that this enzyme is under the control of three codominant alleles at the same locus. Gene frequencies in the two populations have been...

Influenza della temperatura e della salinità su alcuni parametri del ciclo biologico del copepode arpacticoide Tigriopus brevicornis

Paolo Maria Bisol;  Marisa Renier;  Emanuela Tombolan;  Vittorio Varotto — 1979

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

A study on the life cycle of the Copepod Tigriopus brevicornis has been carried out at three temperatures (9°C, 10°C, 27°C) and two salinities (17‰, 34‰). The results show that (a) temperature influences minimum generation time, duration of life and survival; (b) salinity affects sex ratio by a differential mortality of females at low concentrations; (c) both factors modify the fertility values. Moreover, the results indicate that this Copepod has a long life cycle and an exceptionally high adaptability...
