✦ Synopsis

The composition of gas in the vesicles of Sargassum of. Ieptopodum So~nv.g has been investigated. The oxygen content depends upon the oxygen partial pressure of the surrounding medium. It does not depend upon the photosynthetic activity of the vesicle. Evidence is provided that the lower limit of the vertical distribution zone of Sargassum cf. leptopodum So~n~a is not controlled by the vesicles' capability of resisting hydrostatic pressure.

## Abstract In 2001 nine temporary pools of the northern Apennines (Italy) were visited on 13 occasions during the ice‐free season (May to October). The aims of this research were to define the relationships between hydroperiod and other environmental variables and the zooplankton. In total, 49 zoo
