| The so-called 8.2 ka event represents one of the most prominent cold climate anomalies during the Holocene warm period. Accordingly, several studies have addressed its trigger mechanisms, absolute dating and regional characteristics so far. However, knowledge about subsequent climate recovery is still limited although this might be essential for the understanding of rapid climatic changes. Here we present a new sub-decadally resolved and precisely dated oxygen isotope (5180) record for the interval between 7.7 and 8.7 ka BP 10(3) calendar years before AD 1950), derived from the calcareous valves of benthic ostracods preserved in the varved lake sediments of pre-Alpine Mondsee (Austria). Besides a clear reflection of the 8.2 ka event, showing a good... |

| The freshwater ostracods living exclusively in interstitial and/or interstitial and cavernous habitats belong to the Candoninae, Pseudolimnocytherinae, Timiriaseviinae, Kliellinae and Darwinulidae. An assessment of the antiquity of several interstitial ostracod groups has been attempted using direct evidence from the phylogenetical affinities between living hypogean and fossil ostracod species, and indirect evidence from the morphological characters of the subterranean ostracods and from the bio- and paleobiogeographical distribution of the different ostracod groups. |

| The need for better and more systematic descriptions of the chaetotaxy (especially data concerning the shape, structure and pattern of distribution of the setae) is emphasized. The historical developments of studies in chaetotaxy are reviewed. Two basic types of cuticular processes can be recognized: setae and pseudochaetae. The former have sensorial and mechanical functions, the latter only a mechanical function. A special type of seta is the aesthetasc or the chemosensorial receptor. Using the shape and structure of the setae, most of them can be classified in the following categories: simple, plumed, serrate and chelate. The importance of developmental studies for the establishment of homologies in chaetotaxy is stressed. Examples of functional... |
