Historische Rollbilder: Biologie im Blick. Zufallsfund an der Universität Jena

Historical wall charts Different kinds of wall charts (botanical, zoological, human biological), together with the microscope, are important teaching materials for biological education in classrooms and universities. Fallen into oblivion during structural alteration works at the zoological institute, 370 wall charts were sheltered in a special university building (the so‐called “Bunker”). By accident, the collection was rediscovered by members of the research group of Didactics of Biology at the University of Jena at the beginning of 2011. They found 26 zoological wall charts illustrated by the Viennese botanist Paul Pfurtscheller and 28 by the zoologist Rudolf Leuckart from the University of Leipzig.     

Le site de Tögi Ndrawa, île de Nias, Sumatra nord : les premières traces d'une occupation hoabinhienne en grotte en Indonésie

The site of Tögi Ndrawa, Island of Nias, North Sumatra: The first record of a Hoabinhian cave occupation in Indonesia. Although in Indonesia, Hoabinhian sites usually refer to large shell midden dated back from the Holocene period, the Tögi Ndrawa cave in the Island of Nias (North Sumatra) has revealed a thick shell accumulation, sealed in a cavity, and beginning with the end of the Late Pleistocene. Excavations have produced classical Hoabinhian pebble artefacts, a forest and coastal fauna, and human bones. Beyond the new chronological landmarks provided by these findings, they question the extension of the Hoabinhian phenomenon originating from continental Asia, and provide hints about human settlement and use of the environment at this period of prehistory.

Morphometrische Studien anValeriana officinalis s. l. Auswahl,Analyse und Aufbereitung der Merkmale

Valeriana officinalis s. l. is an extremely polymorphic polyploid complex. A multivariate morphometric study is the only adequate method to cope with the diversity largely based on quantitative differences. 50 morphological characters have been carefully chosen with regard to their expected taxonomic relevance. The use of program packages for (multivariate) statistical and taxometric evaluation of the data has been made possible by the development of a series of computer programs. They allow different manipulations of the data as well as the extraction of distance or similarity matrices from mixed-type data (i.e. data containing quantitative as well as binary characters). In addition, a computer-based study of the relationships between variables has been carried out by a grouping of variables into subsets according to their B-coefficients (being defined as the ratio of the average of the intercorrelations among the variables of a group to their average correlations with the remaining variables). This technique can also be applied in cases where parts of the material show extremely different correlation patterns, as inValeriana officinalis s. l.
