Última Een margriet is een margriet is ... Naturalis Haveman, R.. In the Netherlands, usually only one Leucanthemum species is recognised, L. vulgare Lam. Recent field observations suggest that the Leucanthemum species that occurs abundantly in the Netherlands is the tetraploid species L. ircutianum DC instead. A few Dutch specimens in the herbarium collection of Naturalis in L, however, have been identified as belonging to the 'true' diploid L. vulgare. The latter seems to be rare in the Netherlands, and might be confined to a few relict populations. In Nederland word slechts één Leucanthemum-soort onderscheiden die hier bekend staat onder de naam L. vulgare Lam., een diploïde soort. Op basis van veldobservaties moet echter worden geconcludeerd dat de algemeen voorkomende Margriet in Nederland waarschijnlijk de...

Ano: 2017 URL: http://www.repository.naturalis.nl/record/627814 De kleine wrattenbijter Gampsocleis glabra herontdekt in Nederland (Orthoptera: Tettigoniidae) Naturalis Berg, A. van der; Haveman, R.; Hornman, M.. Gampsocleis glabra rediscovered in the Netherlands (Orthoptera: Tettigoniidae) Until recently, Gampsocleis glabra was considered to be extinct in the Netherlands since 1987. In 1999, this species was found in large accounts at the military firing range Oldebroek in the province of Gelderland. Gampsocleis glabra seems to prefer open heath (Genisto-Callunetum danthonietosum) and grassland communities (Galia hercynici-Festucetum ovinae) with a low moss abundance. On the Oldebroekse Heide the vegetation is burnt periodically, with a cyclus of 8 years. It is remarkable that on the Lüneburger Heide (Niedersachsen, Germany) the vegetation is burnt on a large scale too. This is the only other site where G. glabra survived in northwestern Europe.

Ano: 2000 URL: http://www.repository.naturalis.nl/record/215240 Gestolen kenmerken: wat zijn soorten in Rosa sect. Caninae? Naturalis Haveman, R.. In 2011 verscheen in dit tijdschrift een overzicht van de rozensoorten in ons land. Bakker et al hanteren in dit overzicht een artificieel, typologisch soortconcept om orde te scheppen in de chaos van Rosa sect. Caninae, waarbij de variatie via morfologische kenmerken wordt verdeeld in eenheden, waaraan vervolgens de status van soort wordt toegekend. De stand en duurzaamheid van de kelkbladeren, alsmede de doorsnede van het stijlkanaal spelen daarbij een belangrijke rol. Deze kenmerken blijken echter volgens een al in 2003 gepubliceerd artikel10 geheel overerfd te worden via het mannelijke erfelijk materiaal. Bij het doorgeven van erfelijk materiaal aan de nieuwe generatie vindt waarschijnlijk geen recombinatie plaats en worden de vrouwelijke kenmerken,...

Ano: 2016 URL: http://www.repository.naturalis.nl/record/606377 Nieuwe vindplaatsen van de zadelsprinkhaan Ephippiger ephippiger op de noordelijke Veluwe (Orthoptera: Tettigoniidae) Naturalis Delft, J.J.C.W. van; Berg, A. van der; Haveman, R.. New records of Ephippiger ephippiger in the Netherlands (Orthoptera: Tettigoniidae) Ephippiger ephippiger Fiebig, 1784 is one of the most endangered Orthoptera species in The Netherlands. In recent years populations are only known from the central Dutch region Veluwe, heathlands south of the city of Nijmegen and the Brunssummerheide in the province of Limburg. In 1999 several new records from the northern part of the Veluwe became known. The species was found in older parts of the heath where some shrubs and/or large heather plants were present. The management of the heath differs between the sites. At the Oldebroekse Heide one of the largest populations of E. ephippiger in north-western Europe is present, as well as a large population of the extremely...

Ano: 2000 URL: http://www.repository.naturalis.nl/record/217234 Revision of Bolboschoenus (Asch.) Palla (Cyperaceae) in the Netherlands Naturalis Simons, E.L.A.N.; Haveman, R.; Kleyheeg, E.. In the last decades, Van der Meijdenʼs editions of the Heukels’ Flora recognized only a single taxon in the 'Bolboschoenus maritimus group’ for the Netherlands: Bolboschoenus maritimus (L.) Palla, formerly known as Scirpus maritimus L. This is probably because the previously recognized infraspecific taxa were solely based on inflorescence architecture. These characters, however, vary between and within populations, and even within clones or individuals. However, in Central Europe the study of a new character, pericarp morphology, resulted in new insights in the taxonomy of the ‘Bolboschoenus maritimus group’. A species new to science, B. laticarpus Marhold, Hroudová, Ducháček & Zákr., has been reported to occur in the Netherlands as well. In this...
