    De samenstelling van de Nederlandse flora gerelateerd aan de kans op uitsterven (verdwijnen) van plantesoorten in de 20ste eeuw (1995)
    Nationaal Natuurhistorisch Museum [etc.], Leiden
    Details
    Publication Date: 2024-02-08
    Description: Tussen 1840 en 1990 zijn 73 plantesoorten uit Nederland verdwenen (tabel 3); daarnaast zijn in de laatste 25 jaar 14 soorten teruggevonden die als verdwenen werden beschouwd (tabel 4). Het aantal verdwijnende soorten is vanaf 1920 min of meer constant in de tijd: ca. 20 soorten per 20 jaar. Ook recent is er geen toename van het aantal verdwenen soorten geconstateerd, dit ondanks de toename van de bedreiging van veel biotooptypen. De studie toont aan dat er een zeer duidelijk verband bestaat tussen het areaaltype van de soort en de kans op verdwijnen. Soorten met een voorpost-areaal en met een marginaal areaal hebben een veel grotere kans te verdwijnen dan soorten met een centraal of subcentraal areaal; het verdwijnen van zulke soorten is een natuurlijk proces.

    Verspreidingskaarten van de botanische kwaliteit in Nederland uit FLORBASE (1995)
    In:  Gorteria: tijdschrift voor de floristiek, de plantenoecologie en het vegetatie-onderzoek van Nederland vol. 21 no. 1/2, pp. 3-59
    Details
    Publication Date: 2024-02-08
    Description: A method is presented for the assessment of the botanical quality in the Netherlands. This quality is derived from the large national database FLORBASE which contains per square km, data on the presence of indigenous plant species in the period 1975-1990 (in all 4.5 million records). 7 Species were grouped into 28 \xe2\x80\x98ecological groups\xe2\x80\x99 according to the \xe2\x80\x98ecotope classification\xe2\x80\x99 system. 21 According to the fact whether a species is assigned to several ecological groups or a single one, it gets an indication-value ranging from 1/3 up to 1. From each square kilometer the indication-values are counted for each ecological group to form a score. Scores of different ecological groups are not mutually comparable because, for instance, each ecological group has its own number of characteristic species. Therefore scores are normalized to four quality classes. For each ecological group, separate class boundaries are established. According to the score, a square km can be classified as \xe2\x80\x98noise\xe2\x80\x99, \xe2\x80\x98moderately developed\xe2\x80\x99, \xe2\x80\x98good developed\xe2\x80\x99 or \xe2\x80\x98very good developed\xe2\x80\x99. These values are depicted in the maps 5\xe2\x80\x9432 with the colours grey, blue, yellow and red, respectively. The maps thus give the distribution as well as the quality of 28 ecological groups in the Netherlands. The maps are corrected for regional differences in the intensity with which the plant inventories have been carried out. Maps of this kind can be used for various purposes in the national planning on nature related subjects.

    The phylogeny and taxonomic status of the Chlorocystini (sensu stricto) (Homoptera, Tibicinidae) (1995)
    In:  Contributions to Zoology vol. 65 no. 4, pp. 201-231
    Details
    Publication Date: 2024-01-12
    Description: The \xe2\x80\x9cBaeturia and related genera complex\xe2\x80\x9d, as defined earlier (De Boer, 1990) by shared aedeagal characters, is identified as the tribe Chlorocystini (sensu stricto). The Prasiini (sensu stricto) are identified as the sister group of the Chlorocystini (sensu stricto), while the genus Muda is recognized as the nearest outgroup. The phylogeny and biogeography of the sister group and outgroup is briefly discussed. Baeturia kuroiwae Matsumura is transferred to the genus Muda. A phylogenetic reconstruction of all 147 species of the Chlorocystini (sensu stricto) is presented, based on 154 characters and 409 character states. The computer program PAUP 3.1.1 (Swofford, 1993) was used for analysing the data; the genera Prasia and Muda were used as outgroups in this analysis. The results obtained from the computer analysis were slightly modified a posteriori, favouring some presumably phylogenetically important characters over strongly fluctuating ones. These final modifications were carried out with the aid of the computer program MacClade 3.0 (Maddison & Maddison, 1992). A complete data matrix and a list of characters and character states are given in an appendix; for descriptions and illustrations of these characters one is referred to previous publications.
