Myricaria germanica in four alpine river basins of north-eastern Italy
The article provides a picture, updated to 2017, of the presence, abundance, distribution and characteristics of the populations of Myricaria germanica in northeastern Italy in 146 sites distributed in four watersheds (Adige, Brenta, Piave, Tagliamento), subject to different levels of natural and anthropogenic disturbance, but comparable in terms of climate, geology and biogeography. It describes the influence of human activities on river geomorphology and its interactions with M. germanica scrub (habitat Natura 2000 3230), assessing its current threats and future prospects.
In this work the eight species of beetles of the genus Tropiphorus present in Trentino-Alto Adige (Italy) are presented. Tropiphorus norici Yunakov, 2013 is confirmed as a species to be added to the Italian checklist of Curculionidae. Tropiphorus ochraceosignatus is reported for the first time from Piemonte and Friuli Venezia Giulia. Tropiphorus paulae and T. bertolinii are endemic species with a more or less restricted range. Ecological notes of all species are reported, also unpublished ones.
The Geological Map of the Western Dolomites is based on the new mapping and compilation of the entire sedimentary cover
of the Autonomous Province of Bozen/Bolzano. It was carried out as part of the project “Geological Base Map of South Tyrol”.
In the course of this new mapping, new lithostratigraphic terms were introduced, or conventional ones redefined, across the
boundaries of official map sheets. This was not always in line with the Italian national mapping programme CARG. New and
newly defined lithostratigraphic terms are explained below. Their position is shown in the lithostratigraphic table
The finding of a young adult slow worm, coloured black-blue, from the upper Eisack Valley / Valle Isarco (South Tyrol / Alto Adige [Italy]) is reported. The colouring is attributed to a lack of yellow colour pigments (axanthism). Potential advantages and disadvantages that arise from the colouration are discussed. It is believed that the unusual colouration is due to a spontaneous mutation.
At the time of writing this article the specific status of the slow worm occurring in this region is not known. It could be either a specimen of Anguis fragilis Linnaeus, 1758 or one of Anguis veronensis Pollini, 1818, as well as a hybrid form between these two taxa.
Seven species (Cephalozia ambigua, Harpanthus flotowianus, Isopaches decolorans, Schljakovianthus quadrilobus, Solenostoma pumilum, Andreaea nivalis and Dicranella staphylina) are reported for the first time for South Tyrol, three of them (Schljakovianthus quadrilobus, Solenostoma pumilum and Dicranella staphylina) as new for the region of Trentino-Alto Adige/Südtirol. Solenostoma gracillimum, Liochlaena lanceolata and Conostomum tetragonum were re-found after more than 100 years, and seven further species are considered to be very rare (Lophozia ascendens, Nardia compressa, Scapania
uliginosa, Crossidium squamiferum, Dicranum majus, Grimmia anomala and Grimmia caespiticia). A survey of published literature since 2006 is given.
