The absence of Potamogeton lucens L. in an area of Traunsee, Austria, which is heavily impacted by industrial sludges was related to these deposits. The hypothesis that P. lucens L. is affected by the industrial tailings was confirmed by growth experiments of the translocated plants in the field. At the unpolluted reference site of the lake, the plants grew better, they were longer and produced more leaves than at the emission site. 相似文献

The epiphytic invertebrates found on Potamogetonperfoliatus L. in Traunsee, an oligotrophic Alpine lake inAustria, were investigated in August and October 1998 in orderto study the impact of industrial tailings discharged into thelake. 113 taxa were found, 54 could be identified to thespecies level. Their total abundance varied between ca.190,000 and 1,138,000 ind. m-2 lake bottom area. Thisepiphytic assemblage was dominated by Dreissenapolymorpha and Sida crystallina, which resulted in avery low overall species diversity. Multivariate statisticalanalyses revealed significant differences in the communitystructure between three sites, each of them was located at adifferent distance from the site of industrial waste emission.These differences were interpreted as variations which reflectthe patchiness within highly structured habitats rather thanas being the result of the industrial pollution. 相似文献
