Quantitative, time-limited samplings in monthly intervals from June 1995 to August 1996, in combination with the measurement of carapace width of juvenile and adult spiders has revealed the life cycle patterns of the riparian wolf spiders Pardosa wagleri and Pirata knorri and showed the effect of floods on their abundance at the Isar River (Germany, Bavaria). Adults and juvenile spiders are heavily affected by floods but the populations of both species are able to recover quickly. The life cycles of both species are synchronized with the season and display a spring/summer stenochrony. P. wagleri shows a second reproductive phase in early summer. This reproductive behaviour supports the persistence of populations in this disturbed environment.
