Sulle interrelazioni trofiche in due fiumi italiani: il Po e il Garigliano

Ettore Tibaldi — 1971

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

A description of the trophic structure of the river Po and Garigliano is presented. At the same time a comparison was attempted between the two food-webs. The food-web of the river Garigliano, in general, appears to be more "open", whilst that of the river Po seems more complex but not so rich in energy output. The importance of human activity in the two ecosystems is also taken into consideration.

Indagine sulle colonizzazioni perifitiche di un ambiente laterale del fiume Po

Paola Chierici Magnetti;  Milvia Dotti;  Andreina Paoletti di Chiara;  Elio Smedile;  Ettore Tibaldi — 1971

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

The composition of the periphytic populations by means of the immersion of natural substrata (stones) in a stretch of low marshy land of a river was studied. The results obtained with seasonal experiments are reported. The colonization of the substrata is vast during the entire year and, in terms of biomass, is larger in autumn for vegetation and in winter for animals.
