Up-to-date report on the distribution ofHelianthemum lippii(Cistaceae) in Italy
2015
An up-to-date report on the distribution of Helianthemum lippii in Italy is provided also on the basis of the findings by Lojacono-Pojero in 1889 who reported the existence of a relic population in Sicily (southern Italy), which is now thought to be extinct because of human disturbance. Field excursions permitted to confirm the locus classicus reported by Lojacono-Pojero as the other Sicilian localities that have been reported more recently. Based on a careful analysis of the literature the presence of H. lippii is currently excluded in Calabria and Apulia. The main causes that threaten the habitat of H. lippii in Sicily are pointed out according to IUCN Threats Classification Scheme.
A new polyploid species of Limonium (Plumbaginaceae) from the Western Mediterranean basin
2015
A new species of Plumbaginaceae, Limonium irtaensis, is described and illustrated from the Western Mediterranean basin (Iberian Peninsula). The new species is triploid (2n = 26) and shows a papillate stigma and pollen with a fine reticulate exine (B type). A detailed morphological description is given, and its main diagnostic characters are compared with the related species. Conservation status has been assessed according to the IUCN protocol.
Values and challenges in the assessment of coprophilous fungi according to the IUCN Red List criteria: the case study of Poronia punctata (Xylariales…
2020
Coprophilous fungi are specialized microorganisms, playing key roles in ecosystems and in several other contexts, whose protection requires more substantial efforts. This paper aims to highlight and discuss valuable and critical aspects faced during the process of the threat status assessment of Poronia punctata, providing inspirations for future conservation actions.
Widłaczek torfowy Lycopodiella Inundata (L.) Holub w stawach hodowlanych na Śląsku
2017
W pracy przedstawiono przegląd informacji na temat występowania widłaczka torfowego Lycopodiella inundata (L.) Holub oraz opisano nowe stanowiska zlokalizowane w stawach hodowlanych na Śląsku. W Polsce gatunek ten należy do bardzo rzadkich składników flory. W trakcie przeprowadzonych badań stwierdzony został na tym obszarze na 8 stanowiskach. Zagrożeniem dla taksonu na Śląsku, jak i w Europie jest postępująca sukcesja roślinności na stanowiskach.
A case study of the coconut crab Birgus latro on Zanzibar highlights global threats and conservation solutions
2021
Abstract The coconut crab Birgus latro, the largest terrestrial decapod, is under threat in most parts of its geographical range. Its life cycle involves two biomes (restricted terrestrial habitats near the coast, and salt water currents of the tropical Indian and Pacific Oceans). Its dependence on coastal habitat means it is highly vulnerable to the habitat destruction that typically accompanies human population expansion along coastlines. Additionally, it has a slow reproductive rate and can reach large adult body sizes that, together with its slow movement when on land, make it highly susceptible to overharvesting. We studied the distribution and population changes of coconut crabs at 15…
Dwa nowe stanowiska twardziaka pucharowatego Neolentinus cyathiformis w Polsce
2018
Neolentinus cyathiformis (Schaeff.) Della Maggiora & Trassinelli (Gloeophyllaceae, Gloeophyllales, Agaricomycetes) to rzadki grzyb, który na aktualnej Czerwonej liście grzybów wielkoowocnikowych w Polsce posiada kategorię gatunku wymierającego E. Pomimo szerokiego zasięgu (Europa, Azja, Ameryka Południowa) jego stanowiska są nieliczne. W Polsce do tej pory znanych było 20 stanowisk tego gatunku, w tym zaledwie dwa w północnej części kraju. Celem artykułu jest zaprezentowanie dwóch nowych stanowisk: w Ogrodzie Botanicznym Uniwersytetu im. Adama Mickiewicza w Poznaniu (woj. wielkopolskie) oraz w północno-wschodniej części kraju we wsi Rejsztokiemie (woj. podlaskie). Na obu stanowiskach owocni…
A miniature world in decline. European Red List of Mosses, Liverworts and Hornworts
2019
AimThis Red List is a summary of the conservation status of the European species of mosses, liverworts and hornworts, collectively known as bryophytes, evaluated according to IUCN’s Guidelines for Application of IUCN Red List Criteria at Regional Level. It provides the first comprehensive, region-wide assessment of bryophytes and it identifies those species that are threatened with extinction at a European level, so that appropriate policy measures and conservation actions, based on the best available evidence, can be taken to improve their status.ScopeAll bryophytes native to or naturalised in Europe (a total of 1,817 species), have been included in this Red List. In Europe, 1,796 species …

Conservation aspects for chasmophytic species: Phenological behavior and seed strategies of the Central Apennine threatened endemismMoehringia papulo…
2012
Abstract Chasmophytic vegetation growing on the cracks of cliffs in the Mediterranean and in the Euro-Siberian phytogeographic regions shows a great regional diversity, with a large number of endemic plant species, many of them endangered and at risk of extinction. Moehringia papulosa is an example of a threatened plant living in this kind of habitat. It is an endemism of the Marche region in central Italy, whose natural populations are considered as critically endangered (CR) under the IUCN criteria and the habitat is protected by the E.U. (Directive 92/43/EEC) with the habitat 8210 “calcareous rocky slopes with chasmophytic vegetation”. The phenology of natural populations was analyzed, s…
Are Red Lists really useful for plant conservation? The New Red List of the Italian Flora in the perspective of national conservation policies
2013
La nuova Lista Rossa della flora Italiana comprende tutte le "policy" specie italiane e altre specie di nota conservazione e comprende 400 taxa di cui il 65% sono minacciate di estinzione. La Lista Rossa si basa su un enorme data-set georeferenziato utile per gli scopi di conservazione. - The New Red List of the Italian Flora includes all the Italian policy species and other species of known conservation concerns for a total of 400 taxa, 65% of which are threatened with extinction.
