Environmental DNA analysis indicates that migration barriers are decreasing the occurrence of European eel (Anguilla anguilla) in distance from the s…
2020
Abstract The European eel (Anguilla L.) is considered critically endangered by the IUCN Red List, and recruitment remains low. One of the challenges for the species today is migration barriers that limit their habitat. Along the Norwegian coast, like in other countries, the abundance of eels appears to decrease with distance from the sea. This pattern may be a result of factors like water temperature, water quality, competition, and habitat suitability and availability. This study aims to use environmental DNA (eDNA) analysis to investigate the potential relationship between migration barriers and the decreasing occurrence of eels in distance from the sea by the coast of southern Norway. Si…
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.
On the mend of bryophyte conservation in Spain: preparing a proposal for the inclusion of bryophytes in national species protection catalogues
2018
The Spanish bryoflora contains 1291 taxa, 272 of them included in the Spanish Red List under any threat category. Although bryophytes show a low rate of endemicity compared to vascular flora, Spanish administration’s responsibility for the conservation of these plants is very high, since the country has 63 exclusive or rare species on a European or world scale. However, the representation of this group of plants in the Spanish legislation on species conservation is merely anecdotal. Royal Decree 139/2011 of 4 February develops a list of wild protected species (LESRPE and CEEA, Spanish abbreviations) and includes only 10 species of bryophytes, all of them from the Directive Habitats and the …
European Red List of Grasshoppers, Crickets and Bush-crickets
2016
The European Red List is a review of the conservation status of European species according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level, so that appropriate conservation action can be taken to improve their status. This Red List publication summarises results for all hitherto described native European Orthoptera species (grasshoppers, crickets and bush-crickets). All Orthoptera species (grasshoppers, crickets and bushcrickets) native to or naturalised in Europe before AD 1500 (a total of 1,082 species), have been assessed in this Red List. The geographical scope is continent-wide, extending from Iceland in the…
Red List of vascular plants of Tajikistan – the core area of the Mountains of Central Asia global biodiversity hotspot
2020
AbstractCentral Pamir-Alai, which is located almost entirely within the area of Tajikistan, is one of the world hotspots of biodiversity, harbouring ca. 4,300 species and 1,400 endemic plants. The first application of the IUCN Red List criteria reveals that among all native species occurring in Tajikistan 1,627 taxa (38.11%) are threatened, including 23 extinct (0.54%), 271 (6.34%) critically endangered (CR), 717 (16.79%) endangered (EN) and 639 (14.96%) vulnerable (VU). Globally, 20 taxa are extinct, 711 (16.65%) threatened, including 144 (3.37%) critically endangered, 322 (7.54%) endangered and 245 (5.73%) vulnerable. As we found positive correlation between human density and the number o…
What is a tree in the Mediterranean Basin hotspot? A critical analysis
2019
Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-Europ…

Conservation of Ptilostemon greuteri (Asteraceae), an endemic climate relict from Sicily (Italy): state of knowledge after the discovery of a second …
2022
Ptilostemon greuteri is one of the most endangered and poorly studied woody vascular plant species of the Mediterranean Basin, endemic to Sicily (Italy). Several peculiar traits confer to P. greuteri a character of uniqueness and an enigmatic attractiveness. In fact, at first glimpse the largest individuals of this species remind the most remarkable and peculiar cases of herbaceous genera (e.g., Echium, Senecio) turned woody on insular or insular-like mountain ecosystems. Following the discovery of a second population of this rare species, a project aiming at the study and conservation of P. greuteri was set up. We present here updated information on the distribution, conservation status, b…
A new look atOrthotrichum scanicumGrönvall (Orthotrichaceae, Bryophyta)
2009
Abstract Orthotrichum scanicum Gronvall has been considered a European endemic whose main range corresponded to the central and northern region of the continent, and it is currently included in the 2007 IUCN World Red List as Vulnerable. However, a large number of recent reports and the examination of herbarium specimens have remarkably expanded the limits of its area in the Mediterranean and Caucasian regions. Additionally, the revision of the original collections of Orthotrichum holmenii from Kazakhstan shows that this taxon is conspecific with O. scanicum. An updated description of the species comprising the known range of its morphological variability is provided, and its exclusion from…
<p><strong>Typification of the name <em>Galatella sorrentinoi </em>(Asteraceae)</strong></p>
2020
Tripolium sorrentinoi (Todaro 1858: 42) Raimondo & Greuter (2005: 59) (Asteraceae) is a species endemic to Sicily. In this island, it grows on badlands in the Palermo, Enna, Caltanissetta, and Agrigento Provinces, between the coast and the hinterland mountains. Its phytogeographical interest is remarkable because it occurs in selective habitats, where it is often the sole phanerogamic inhabitant. Due to its small population size and to a continuing decline of mature individuals, T. sorrentinoi was assessed as “Vulnerable” (VU) according to the IUCN criteria (Domina & Troia 2016).
