Indagine sulle colonizzazioni perifitiche di un ambiente laterale del fiume Po
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.
