subfossil Cladocera - Opis:
- This pa per pres ents dis cus sion on the re sults of sub fos sil Cla do cera analy ses from five lakes in Po land (Przedni Staw Lake, Per es pilno Lake, Gooeci¹¿ Lake, Imio³ki- fossil lake and Os trow ite Lake). The Cla do cera are rep re sented in sediments by re mains of plank tonic (Bos mini dae, Daph ni dae) and lit to ral (Chy do ri dae) forms. Cla do ceran as sem blage phases (“ecos tra tigra phy”) were de ter mined on the ba sis of changes in domi nance of in di ca tor spe cies and past ecologi cal con di tions were re con structed. The re sults are be ing dis cussed from the view point of cli mate change and anthro po genic ac tiv ity and their role in the lake evo lu tion. Moreo ver, an at tempt to use the cla do ceran phases for stra tigraphic di vi sion of the Late Gla cial and Holo cene was made. Dur ing the Bøl ling/Al lerød in ter sta dial, dis tin guished on the ba sis of pol len analy sis, Cla do cera in di cated short phase of bad con di tion (dry or cold?), proba bly as the Old Dryas cli mate re sults. The be gin ning of Holo cene is char ac ter ized, in moun tain and low land lakes, by high in -crease in the number of spe cies and speci mens of Cla do cera. This de scribed clear warm ing and marked the bound ary Late Gla cial/Holo cene. It was in di cated that the “ecos tra tigra phy” based on Cla do cera can be use ful for cli ma to stratigra phy, if cli mate was the ma jor fac tor con trol ling the de vel op ment of fresh wa ter lakes.
