. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. 94 Renate van den Elzen The wide acceptance of the first symposium and the international efforts sketched above are indications that the scientific community has recently adopted a more positive attitude towards taxonomical expertise, historical aspects of ornithology and phylogenetic research. Articles on these topics published in the Journal für Ornithologie, the official organ of the German Ornithologists' Society (DO-G), have been summa- rized since WWII (Fig. 1; shown in pentades). One can observe well that, after a period of stagnation between 1970 and 1990, the number of articles on avian systematics and phylogeny has slowly increa- sed. The „record" height of historical and taxonomic articles in 2000 is due to the 150''^ anniversai7 of DO- G, when ornithological research traditions received special attention. 20. 1951 1960 1970 1980 1990 2000 Fig. 1: The amount of papers on systematics, taxonomy and phylogeny published in Journal of Ornithology shown in pen- tades. Not only have new molecular methods led to a new interest in species limits and phylogenetic research, but also the worldwide loss of biodiversity at both geographic and taxonomic levels has found a political response, reflected in increased funding for biodiver- sity programmes over the last decade. ;/'r¿/- watchers, ornithologists and bird conservation organ- (Herkenrath 2002)... also institutions housing scientific bird collections play an important part in this respect (Collar 2003).
