Polska - Opis:
- This pa per pres ents the re sults of fos sil Cladocera anal y sis us ing ma te rial ob tained from seven palaeolakes of the Eemian inter gla cial lo cated in Po land. The main aim of this study was to in ves ti gate the state of pres er va tion and diver sity of spe cies in the Eemian Cladocera. The stud ied Eemian lakes were formed at the end of the Wartanian Gla ciation in tun nel and ket tle holes. They had pre served a con tin u ous re cord of en vi ron men tal changes through out the Eemian inter gla cial, un til the Vistulian Gla ci ation. Cladocera fos sils found in Eemian sed i ments were thin ner and had a more dam aged struc ture than fos sils from the Ho lo cene. Low de gree of fos sil pres er va tion forced to de velop an al terna tive method for prep a ra tion of the fos sils for the mi cro scopic anal y sis. Cladocera spe cies found in the ex am inedpalaeolakes cor re sponded to the pres ent-day spe cies in hab it ing Po land and Cen tral and North ern Eu rope. The changes in species composition resulting from climate changes corresponded to the current geographic distribution of Cladocera. De spite the poor con di tion of the ob tained fos sil re mains, the re sults showed that cladoceran fos sils in sed i ments of palaeolakes may be used in the re con struc tion of en vi ron men tal con di tions from the pe riod pre ced ing the last gla ci ation.
