“…These exoskeletons might be preserved under certain circumstances, especially in peatland, lake and bog sediments, forming subfossil or fossil taphocenoses (Erickson, 1988;Krivolutsky et al, 1990;Solhøy & Solhøy, 2000). These and the subfossils of aquatic Oribatida, may contribute important information on environmental changes (Schelvis, 1990;Erickson, 1996;Solhøy, 2001;Erickson et al, 2003).…”

Oribatid mites are primarily terrestrial. Only about 90 species (less than 1% of all known oribatid species) from 10 genera are truly aquatic, with reproduction and all stages of their life cycle living in freshwater. Adaptation to aquatic conditions evolved independently in different taxa. However, many terrestrial species can also be found in aquatic habitats, either as chance stragglers from the surrounding habitats, or from periodic or unpredictable floodings, where they can survive for long periods. In spite of their low species richness aquatic oribatids can be very abundant in different freshwater habitats as in lentic (pools, lakes, water-filled microhabitats) or flowing waters (springs, rivers, streams), mainly on submerged plants. The heavily sclerotized exoskeletons of several species enables subfossil or fossil preservation in lakes or bog sediments.

For technical reasons the number of authors shown on this cover page is limited to 10 maximum. IntroductionIn 2004 a large, more than 4 m deep building excavation was made in Wageningen ( Fig. 1) in order to prepare the foundation of a new university building (so-called Forum Building). Dr Monique Heijmans of the Nature Conservation and Plant Ecology Group of Wageningen University informed the first author about a peat deposit, covered by a lake deposit, as it was exposed in the profiles of the building excavation. The Wageningen-Forum site is situated in a former Saalian tongue basin. During the Weichselian this basin was filled in with alternating fluvial meltwater deposits from the ice-pushed ridges and aeolian cover sands. During relatively humid phases drain water from the ice-pushed ridges caused seepage in the basin and therefore lakes and fens could develop in the depressions in the landscape. Lake sediments and peat deposits were overblown with sand during periods of aeolian activity. The Forum site shows an example of well-preserved peat and lake sediments covered by aeolian sand. In the same tongue basin northwest of Veenendaal a peat deposit of Allerød AbstractBotanical microfossils, macroremains and oribatid mites of a Weichselian interstadial deposit in the central Netherlands point to a temporary, sub-arctic wetland in a treeless landscape. Radiocarbon dates and OSL dates show an age between ca. 54.6 and 46.6 ka cal BP. The vegetation succession, starting as a peat-forming wetland that developed into a lake, might well be linked with a Dansgaard-Oeschger climatic cycle. We suggest that during the rapid warming at the start of a D-O cycle, relatively low areas in the landscape became wetlands where peat was formed.During the more gradual temperature decline that followed, evaporation diminished; the wetlands became inundated and lake sediments were formed. During subsequent sub-arctic conditions the interstadial deposits were covered with wind-blown sand. Apart from changes in effective precipitation also the climate-related presence and absence of permafrost conditions may have played a role in the formation of the observed sedimentological sequence from sand to peat, through lacustrine sediment, with coversand on top. The Wageningen sequence may correspond with D-O event 12, 13 or 14. Some hitherto not recorded microfossils were described and illustrated.Keywords: Dansgaard-Oeschger cycles, macrofossils, non-pollen palynomorphs, Oribatida, pollen...

“…Nevertheless, some species adapted also to xeric conditions or high values of humidity. These minute arthropods are usually preserved well enough in lacustrine or fluvial sediments and in sufficient numbers to be useful as proxies in investigations of Quaternary paleoclimate, paleoecology and stratigraphy (Solhøy and Solhøy, 2000;Solhøy, 2001;Polyak et al, 2001). Five species were identified in the studied samples and four of them are new to science.…”

Invertebrate fossils from cave sediments: a new proxy for pre-Quaternary paleoenvironments

et al. 2011

Abstract. Five samples of clastic sediments from interior cave facies taken in three Slovenian relic caves (Trhlovca, Račiška pečina, and a cave inČrnotiče Quarry, Classical Karst, SW Slovenia) provided invertebrate fossil remains. Most of them belong to Oribatida but sparse individuals of Cladocera and insects were also identified. They represent the first pre-Quaternary invertebrate fossils found in sediments of continental temperate climate. The Pliocene/Pleistocene age of the sediments was determined by paleomagnetic dating chronologically calibrated by micromammal biostratigraphy. Invertebrate fossils could be validated as new proxy for the study of cave sediments due to their suitability for ecological and paleogeographic correlations in caves and outside the caves. They also bring additional information about cave formation and karst hydraulic regime in the area. Although the number of remains was very low, it is evidence that climatic conditions in caves allow a better preservation of fossil remains of some groups as compared to most of the surface habitats. This may open a new direction in the study of cave sediments.
