Opis:
Cladoceran remains preserve selectively in lake sediments. Possibly all Cladocera species leave at least some identifiable remains in lake sediments. Exosceletal body parts of families Chydoridae and Bosminidae preserve best but other families are only variably represented in sediments by their outer body parts. Identification of all possible remains helps to achieve more precise palaeolimnological reconstruction of past ecosystems by Cladocera analysis. This article describes, together with photograph and line drawing the subfossil post-abdomen and post-abdominal claw of Ceriodaphnia, previously not widely identified.

Sub fos sil head shields of A. protzi were found in sedi ment cores taken from lakes in Den mark, Swe den, Fin land, Es to nia and Po land. De spite the rar ity of the spe cies this sug gests a wide dis tri bu tion of A. protzi in north ern Europe. The ecol ogy of A. protzi is poorly known. The en vi ron mental spec -trum of the find ing sites was wide and ranged from rela tively nu tri ent poor clear wa ter lakes to eutrophic tur bid wa terlakes, in di cat ing that A. protzi is not nar rowly re stricted. Most of the lakes were, how ever, meso- eutrophic with neu tral to high pH, and with a rela tively low abun dance of sub merged mac ro phytes. How ever, we can not ex clude the pos si bility that A. protzi mainly lives in ground wa ter and is only oc ca sion ally trans ported into lakes.

The new form did not dif fer from typ i cal A. harpae in the mor phol ogy of the postabdomen, head pores or any ap pend ages.

Opis:
Subfossil trunks of oak (Quercus robur L. and Q. petraea Lieb.) are fundamental for construction of long dendrochronological standards for southern Poland. In the last three years over 400 new oak trunks from alluvial deposits from the basins of the rivers Vistula and Odra were analysed. Most trunks came from the last 2500 years and the produced local chronologies permitted for improvement of the standard chronology POLAND2, covering the period 474 BC-I 555 AD. Subfossil oak trunks from several sites in the river Vistula basin (Grabie, Wolica, Podolsze and others) and from alluvia of the river Odra in Wrocław enabled construction of a new long chronology C_3000E, spanning the years 1795-612 BC. This chronology was absolutely dated through teleconnection with standards for southern Germany. A row of floating chronologies, dated with the radiocarbon method, was established for the older periods of Holocene. They cover the following intervals: ca. 670-400 BC, ca. 2200-1900 BC, ca. 3400-3100 BC, ca. 3800-3600 BC and ca. 6650-6150 BC. Subfossil oak chronologies constructed by the author, together with standards based on living trees, monuments of wooden architecture, and archaeological timbers from Wielkopolska (449- I 994 AD), Lower Silesia (780-1994 AD) and Małopolska (910-1997 AD) practically allow for absolute dating of oak timbers from the area of southern Poland coming from the last 4000 years.

Of Daph nia spp. which are very com mon in zoo plank ton as sem blages of lakes, usu ally only postab domi nal claws and ephip pia are found.

Daph nia claws, shell mar gins and tail spines were found also in sur face sam ples of 17 Fin nish lakes and thus the abun dance of tail spines could be com pared with that of postab domi nal claws. The re sults showed that in most cases the tail spines are more abun dant than postab domi - nal claws and may give a closer es ti mate of the true abun dance of Daph nia. How ever, in some lakes claws were clearly more fre quent than tail spines.

Opis:
In this study we compared chydorid cladoceran (Chydoridae) taxa and assemblages from sediments of 6 Polish and 6 sq Finnish lakes and investigated if the difference in climate of these two countries can be detected in the cladoceran data. The data were analysed in terms of I) average relative proportions of chydorid taxa during the history of each lake and by 2) redundancy analysis (RDA) to explain the present effect of environmental variables (altitude, area, maximum depth, mean annual temperature, mean summer temperature and length of the growing season) on species abundances. The redundancy analysis (RDA) enabled us to distinguish groups of taxa I) with a high thermal preference 2) associated with small, cold-water lakes and 3) associated with shallow lakes. There are clear differences in the dominant chydorid taxa and in the relative proportions of many other chydorid taxa between the two countries since the end of the last glaciation. Although these differences first of all appear to reflect the climatic difference, the influence of many other environmental factors, controlling the living conditions of particular chydorids have been raised and considered. Further studies with larger data are needed before the role of climate can be reliably separated from other elements of environment.
