    Notes: Abstract In this paper we discuss the basic principles of discrete event, individual oriented, data based modelling in ecology, and we present an application of this modelling strategy. The strategy is contrasted with some more conventional modelling strategies with respect to its purpose, its basic units and its heuristic properties. INSTAR applies this modelling strategy to the simulation of the fluctuations of the population structure and density of microcrustaceans through the year. The model encompasses one microcrustacean species at a time, and its interface with the rest of the ecosystem; it has been applied to several Cladocera and Copepoda species in a shallow eutrophic lake in the Netherlands (Vijverberg & Richter 1982a, b). Possibilities for extending the model are discussed.

    Description / Table of Contents: Structure of BenzazarsoleBenzazarsole crystallizes in the space group Pna21 with a = 8.283, b = 5.560, c = 14.647 Å and with 4 formula units per units cell. The structure was determined by X-ray structure analysis and refined to a final R value of R = 0.04. The arsenic atom has the coordination number 2 with significantly different bond lengths to the adjacent carbon atoms (1.82 and 1.92 Å). The estimated bond lengths and the strict planarity confirm the conclusion of benzazarsole being an aromatic molecule. The structure of benzazarsole is compared with the structures of benzimidazole and benzazaphosphole.
    Notes: Benzazarsol kristallisiert in der Raumgruppe Pna21 mit den Gitterkonstanten a = 8,283, b = 5,560, c = 14,647 Å und 4 Formeleinheiten pro Elementarzelle. Die Struktur wurde mittels Röntgenkristallstrukturanalyse bestimmt und bis zu einem R-Wert von R = 0,04 verfeinert. Das Arsenatom ist zweifach koordiniert und zeigt zu den benachbarten Kohlenstoffatomen signifikant unterschiedliche Bindungslängen (1,82 und 1,92 Å). Die gefundenen Bindungslängen und die strenge Planarität stützen die Vermutung, daß Benzazarsol ein aromatisches Molekül ist. Die Struktur des Benzazarsols wird mit den Struktur en von Benzimidazol und Benzazaphosphol verglichen.
