The history of diatom research in The Netherlands and Flanders is summarized in this report. A. van Leeuwenhoek observed diatoms as early as 1702. The first inventories were made in The Netherlands by R. B. van den Bosch (1846) and in Flanders by J.-J. Kickx (1867). Diatoms were already used in geological research in the second half of the nineteenth century. The Synopsis by H. van Heurck (1880–1885) enabled many twentieth century workers to do applied research for geological and ecological purposes. 相似文献

Butterfly monitoring started in the Netherlands in 1990 and in Flanders in 1991. During the last few years butterflies have been counted at nearly 300 sites. This high number of transects makes it possible to calculate not only national, but also regional and habitat-indices for many species. Special attention is paid to Red list species in the Netherlands. In the near future the number of sites per species on this list is to be increased to at least 20. This can be achieved by a Red list monitoring scheme, in which monitoring is restricted to the flight period of the species. 相似文献

This paper analyses the actual meaning of a transcendental philosophy of biology, and does so by exploring and actualising
the epistemological and metaphysical value of Kant's viewpoint on living systems. It finds inspiration in the Kantian idea
of living systems intrinsically resisting objectification, but critically departs from Kant's philosophical solution in as
far as it is based in a subjectivist dogmatism. It attempts to overcome this dogmatism, on the one hand by explicitly taking
into account the conditions of possibility at the side of the subject, and on the other hand by embedding both the living
and the knowing system into an ontology of complexly organized dynamical systems. This paper fits into the transcendental
perspective in acknowledging the need to analyse the conditions of knowability, prior to the contents of what is known. But it also contributes to an expansion and an actualisation of the
issue of transcendentality itself by considering the conditions of possibility at the side of the object as intrinsically
linked to the conditions of possibility at the side of the subject. 相似文献
