A location (area 10 km²) of the agile frog (Rana dalmatina Fitz. in Bonaparte) in a southwest part of the Sandomierz Valley (southern Poland), was surveyed during 4 breeding seasons (1999–2002). Eighteen breeding sites of brown frogs were inspected for their characteristics, presence and numbers of egg-batches, and time of egg deposition. Breeding sites were typically temporary, small, and shallow waters (area 5–30 m², depth <50 cm). The agile frog was found to co-occur only with the common frog (Rana temporaria L.) in most of the sites. Based on the number of egg-batches, the agile frog was more numerous (total of 315 batches in year 2002) than the common frog (163). Over the four years of the study, there were no significant fluctuations in the numbers of eggs. The two species did not differ significantly in their choice of the habitats, except for the sites with low water pH, used predominantly by the agile frog. Habitat niche overlap was high (Pianka’s O = 0.86). In the acid peat bogs (water pH about 4.5) most of the eggs degenerated.

This paper analyses the abundance of breeding pairs and the location of nesting sites of partridges as related to vegetation structure in the nest surroundings in two areas with very different partridge densities and arable landscape patterns (Central Germany and Eastern Poland). Study objective was to identify underlying causes of the more than 100 fold difference in population density of this species in these two areas of Central Europe. Our results suggests that the very limited availability of appropriate nesting habitats with an open canopy structure and low leaf area index is one of the key factors being responsible for the very low recent population density, and the past rapid decline, of partridge in the modern agricultural landscape of western Central Europe.
