First record for the flora of Italy and lectotypification of the name Linum elegans (Linaceae)
2017
Linum elegans has been detected in calcareous rocky garrigues on the Gargano promontory (Apulia, SE-Italy), representing the first record for the Italian flora and the first one outside the Balkan Peninsula. The geographical disjunction may provide evidence for past amphi-Adriatic/amphi-Ionic terrestrial connections. The population found was ascribed to L. campanulatum in the past. As a consequence, a comparison between these two species is undertaken. Furthermore, the name L. elegans is here lectotypified on a specimen preserved at G, and the IUCN assessment of the species in Italy is briefly discussed.
Staying alive on an active volcano: 80 years population dynamics of Cytisus aeolicus (Fabaceae) from Stromboli (Aeolian Islands, Italy)
2020
Abstract Cytisus aeolicus is a narrow endemic species restricted to the Aeolian archipelago (SE Tyrrhenian Sea, Italy) and it is one of the most evolutionarily isolated plants in the Mediterranean flora. Historical and literature data suggest that both metapopulations and isolated individuals of C. aeolicus are gradually shrinking. Field investigations and drone images demonstrate that the C. aeolicus metapopulation from Stromboli experienced a strikingly fast increase during the last decades. As of 2019, more than 7000 ± 3000 mature individuals occur on Stromboli, i.e. 14 to 20 times more than those counted during the last census, 25 years ago. The diachronic analysis of aerial photos conc…
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 …
Habitat fragmentation and anthropogenic factors affect wildcat Felis silvestris silvestris occupancy and detectability on Mt Etna
2019
International audience; Knowledge of patterns of occupancy is crucial for planning sound biological management and for identifying areas which require paramount conservation attention. The European wildcat Felis silvestris is an elusive carnivore and is classified as ‘least concern' on the IUCN red list, but with a decreasing population trend in some areas. Sicily hosts a peculiar wildcat population, which deserves conservation and management actions, due to its isolation from the mainland. Patterns of occupancy for wildcats are unknown in Italy, and especially in Sicily. We aimed to identify which ecological drivers determined wildcat occurrence on Mt Etna and to provide conservation actio…
Notas taxonómicas y distributivas sobre <em>Serapias lingua</em> subsp. <em>tunetana</em> (Orchidaceae), una rara espècie end…
2019
Serapias lingua subsp. tunetana, una rara orquídea endémica con área de distribución restringida en Túnez, al norte de Túnez, ha sido redescubierta lejos de su localidad tipo después de 22 años. Desde su primer hallazgo en 1996 y su descripción publicada en 2005, la subespecie no se había encontrado nuevamente y se presume que se extinguió o fue identificada erróneamente. En este trabajo se proporciona una descripción detallada de la subespecie que justifica una enmienda a su descripción, y se aporta asimismo un mapa de distribución y varias fotografías. Se listan las principales afinidades de la subsp. tunetana con los táxones más estrechamente relacionados dentro del grupo de S. lingua qu…
Hieracium pollinense (Asteraceae), an endemic species to the Pollino National Park (Southern Italy) rediscovered
2017
Abstract The presence of Hieracium pollinense Zahn in Italy is confirmed here after 132 years since its first description based on a single collection made in 1877 in the Mt. Pollino. It is a calcicolous species, so far represented by one population, belongs to the H. sect. Villosa. In line with the IUCN criteria its conservation status assessment is “endangered”.
The use of ecological traits in extinction risk assessments: A case study on geometrid moths
2008
Identifying ecological traits that make some species more vulnerable than others is vital for predictive conservation science. By identifying these predisposing traits we can predict which species are most prone to decline and gain an understanding of the reasons behind the decline. The aim of this study was to determine the ecological traits that best predict extinction risk and distribution change in Finnish geometrid moths and to develop an understanding of the biological connections between these traits and threats. We found that larval specificity, overwintering stage and flight period length predicted distribution change and extinction risk. There was also an interaction effect betwee…
An annotated checklist of bryophytes of Europe, Macaronesia and Cyprus
2020
Introduction. Following on from work on the European bryophyte Red List, the taxonomically and nomenclaturally updated spreadsheets used for that project have been expanded into a new checklist for the bryophytes of Europe. Methods. A steering group of ten European bryologists was convened, and over the course of a year, the spreadsheets were compared with previous European checklists, and all changes noted. Recent literature was searched extensively. A taxonomic system was agreed, and the advice and expertise of many European bryologists sought. Key results. A new European checklist of bryophytes, comprising hornworts, liverworts and mosses, is presented. Fifteen new combinations are propo…
The relevance of urban agroforestry and urban remnant forest for avian diversity in a densely-populated developing country: the case of Port-au-Princ…
2021
9 pages; International audience; Urban green spaces can contribute to conserve some of the original avian diversity in urbanized landscapes. However, the relative contribution of urban agriculture vs. urban forest remnants to the preservation of the avifauna in large cities, particularly in developing countries in the tropics, remains poorly documented. We assessed bird assemblages in the densely-populated capital city of Port-au-Prince in Haiti, one of the poorest countries in the world. From early January to late April 2018, 10 censuses per site were conducted in 16 urban green sites, consisting of 8 unexploited, private forest patches and 8 agroforestry plantations, embedded within the u…
New national and regional bryophyte records, 67
2021
Bulgaria. Samokov Region, Rila Mountains, Rila National Park, N slopes of peak Deno, on granite slabs and scree, collected with occasional sporophytes, 42.19709°N, 23.60322°E, 2780 m a.s.l, 17 September 2019, leg./det. R. Natcheva s.n. (SOM 9811-B). This arctic-alpine species has a north Holarctic circumpolar distribution and this is the first report of Andreaea blyttii for SE Europe. It is its southernmost locality and extends its range further south in Europe. The Rila Mountains are the highest in the Balkan peninsula and A. blyttii was found near the highest summit (Mussala, 2925 m a.s.l.). In Bulgaria the genus Andreaea is also represented by A. alpestris (Thed.) Schimp. and A. rupestri…
