Evolution and taxonomic split of the model grass Brachypodium distachyon.
The substantial phenotypic, cytogenetic and molecular differences detected among the three B. distachyon sensu lato cytotypes are indicative of major speciation processes within this complex that allow their taxonomic separation into three distinct species.
A systematic approach to subtribe Loliinae (Poaceae:Pooideae) based on phylogenetic evidence
Combined analysis of nucleotide sequences from the nuclear ITS and chloroplast trnL-F regions and structural characters recovered a consensus topology that shows Loliinae to be monophyletic and possessing two main clades-the fine-leaved Festuca clade that includes Ctenopsis, Micropyrum, Narduroides, Psilurus, Vulpia, and Wangenheimia.
A Revision of Plagiochila sect. Plagiochila in the Neotropics
A taxonomic revision emphasizing characters of gametophytes as well as sporophytes is presented for Plagiochila, and the great number of synonyms proposed clearly demonstrates the need for a comprehensive taxonomic revisions of neotropical Plag Antiochila.
Ploidy level variability of some Central European fescues(Festuca subg. Festuca, Poaceae)
Using flow cytometry, ploidy levels for 205 living samples of various European species of Festuca L. subg.Festuca were determined and about 23 taxa and two spontaneous hybrids originating from natural populations from Austria, the Czech Republic,France,Hungary,Germany,Italy,Poland,Romania and Slovakia were studied.
Notes on the infrageneric classification of Festuca L. (Gramineae)
Based on results of recent phylogenetic studies, two new sections of Festuca L. (F. sect. Lojaconoa, F. sect. Dimorphae) are described from the Euromediterranean region. Festuca sect. Lojaconoa is
Novelties in Festuca (Gramineae-Poeae) from southern Bolivia
A new species,Festuca samensis, belonging to theF. lilloi group (subgen.Festuca), is described from the Tarija region in southern Bolivia. The limits of theFestuca lilloi group are revised andF.
A complete digitization of German herbaria is possible, sensible and should be started now
Plants, fungi and algae are important components of global biodiversity and are fundamental to all ecosystems. They are the basis for human well-being, providing food, materials and medicines.
Neoplasia in the Siberian weasel (Mustela sibirica): two case reports of fibrosarcoma and interstitial cell tumour
Two cases of neoplasia occurred in two adult Siberian weasels (Mustela sibirica) in a game reserve in southern Lower Saxony, Germany, and were demonstrated with regard to clinical aspects and discussed on the basis of their pathomorphological features.
