Effects of pool size and isolation on amphibian communities

摘要: Abstract An investigation of the presence amphibians was carried out in 38 old and 39 recently constructed pools. In order to assess possible effects pool size isolation on number species, characteristics pools surrounding landscape were analysed by means (stepwise) multiple regression analysis. all analyses we corrected for habitat variables concerning pool. Significant found only. both new species turned be positively influenced vicinity a wood. Woodland is considered here as an element increasing connectivity part land amphibians. Pool age best predictor The three most abundant displayed differences colonization rate. These related their abundance.
