Abstract

The goal of this study was to broaden current floristic understanding of five ravines, with different altitudes and characteristics, present along the Umbro-Marchegian Apennine chain, and to examine how the distribution of the bryoflora is conditioned by geomorphological and microclimatic aspects, as well as man's intervention. The flora list derives almost exclusively from unpublished data of explorations conducted in 2006 and 2007. Initial analysis of this list indicates that the bryoflora is more characterized by the presence of the river at the base of the ravine than by the size of the ravine itself, for there is a considerable number of species of aquatic and stillicidous environments, rather than species related to climatic factors. In addition, the imperviousness of the ravines limits the presence of tourists, which generally determines the entrance of cosmopolite species of high ecological importance, reducing the quality of a given ecosystem. In addition, the presence of Conocephalum salebrosum is signalled for the first time in Italy. [ABSTRACT FROM AUTHOR]

Abstract

The objective of this study is to provide an updated conservation status of all liverworts and hornworts in the Italian territory, evaluated according to IUCN's Guidelines for Application of IUCN Red List Criteria at Regional Level. Overall, 27.4% of taxa assessed in this study are assigned to a risk category and, therefore, considered threatened in Italy. Four liverworts are considered as Extinct, two liverworts and one hornwort Possibly Extinct at regional level. Moreover, a further 9.8% are assessed as Near Threatened, 10.8% as Data Deficient and 49.7% as Least Concern. Most threats are co-occurring, indicating that many taxa are subjected to a set of correlated adverse processes. The main IUCN major threats identified were natural system modifications (i.e. dam construction, increases in fire frequency/intensity, and water management/use), climate change (mainly increasing frequency of droughts and temperature extremes), agriculture (including pollution from agricultural effluents) and aquaculture.
