The principle of frozen evolution and its manifestation in the fossil record: the brachiopod genus Aegiromena Havlíček, 1961 (Upper Ordovician, Czech Republic)
Mikuláš, Radek
2008 - English
Sled paleopopulací ramenonožců rodu Aegiromena ve svrchním ordoviku Barrandienu vykazuje charakteristické prvky, které lze dobře objasnit aplikací koncepce tzv. zamrzlé evoluce. Počáteční rychlé změny morfologie vyvolané změnami substrátu dna v mělkém moři jsou vystřídány stabilitou morfologie a neschopností účelně reagovat na změny konzistence substrátu (objevují se už pouze drobné změny v konfiguraci svalových vtiskům nepatrné změny tvaru schránky a fluktuace velikosti jedinců); rod posléze vymírá ještě před nástupem drastických změn přírodního prostředí na hranici ordovik-silur. The presented study is in a good agreement with the idea of a frozen evolution of the genus Aegiromena, or, more precisely, it illustrates a gradual disappearance of the ability to respond to the environmental change by a selectively advantageous change in its morphology. After its freezing, further evolution of Aegiromena brings very little news; only subtle changes in the size of adults, subtle and variable changes in the width/length ratio, and a changing variability of muscular imprints can be noted.

Feasibility of karst hydrogeological research in the Loferer Schacht area, Loferer Steinberge, Austria
Žák, Karel
2008 - English
The main purpose of this report is to make a feasibility study for a karst hydrogeological project in the Loferer Schacht cave and adjacent area, Loferer Steinberge, Austria. From a hydrogeological point of view, the known part of this cave system (vertical cave extent +9.8/-796.7 m, mapped length 7,800 m) occurs within the unsaturated (vadose) zone. Based on a pilot field survey, evaluation of the geological structure, and a preliminary study of groundwater residence time using oxygen stable isotopes it can be concluded that the area is not suitable for a detailed project. The most principal obstacles for such a study are: i. the character of the dis-charge sites located in talus accumulation, which do not allow precise measurement of the discharge; ii. the long storage of precipitation in the recharge area as perennial snowfields and ice plugs in swallow holes; and iii. the problematic use of artificial water tracers because the springs are used as drinking water.
