Revision of the genus Hantzschia (Bacillariophyceae) on Livingston Island (South Shetland Islands, Southern Atlantic Ocean)
Methods – Using both Light Microscopical and Scanning Electron Microscopical techniques, the morphology of all Hantzschia taxa, present in the samples from Livingston Island, has been analysed. Each taxon is compared with all other possible similar Hantzschia taxa, known worldwide.
Key results – Apart from the already known Hantzschia abundans and H. amphioxys f. muelleri, five new Hantzschia species are described: Hantzschia acuticapitata Zidarova & Van de Vijver sp. nov., H. confusa Van de Vijver & Zidarova sp. nov., H. hyperaustralis Van de Vijver & Zidarova sp. nov., H. constricta Van de Vijver & Zidarova sp. nov. and H. incognita Zidarova & Van de Vijver sp. nov.
Conclusions – The obtained results confirm the presence of a typical and highly specific non-marine diatom flora in the Antarctic Region and contradict the generally accepted idea about the cosmopolitanism of diatoms.

Plant Ecology and Evolution (a continuation of Belgian Journal of Botany, incorporating Systematics and Geography of Plants) is an international journal devoted to ecology, phylogenetics and systematics of all 'plant' groups in the traditional sense (including algae, cyanobacteria, fungi, myxomycetes), also covering related fields such as comparative and developmental morphology, conservation biology, ecophysiology, evolution, phytogeography, pollen and spores, population biology, and vegetation studies. It is published by the Royal Botanical Society of Belgium and the Botanic Garden Meise and contains original research papers, review articles, checklists, short communications and book reviews.
