Hotspots of species richness, threat and endemism for terrestrial vertebrates in SW Europe

2011

The Mediterranean basin, and the Iberian Peninsula in particular, represent an outstanding “hotspot” of biological diversity with a long history of integration between natural ecosystems and human activities. Using deductive distribution models, and considering both Spain and Portugal, we downscaled traditional range maps for terrestrial vertebrates (amphibians, breeding birds, mammals and reptiles) to the finest possible resolution with the data at hand, and we identified hotspots based on three criteria: i) species richness; ii) vulnerability, and iii) endemism. We also provided a first evaluation of the conservation status of biodiversity hotspots based on these three criteria considerin…

Ferula sommieriana (Apiaceae), a new species from Pelagie Islands (Sicily)

2021

Ferula sommieriana, a new species occurring in Lampedusa and Linosa, islands of Pelagie Archipelago in the Sicilian Channel, is described and illustrated. Previously it was attributed to F. communis, from which it differs in several features regarding mainly the morphology and anatomy of terminal leaf lobes and mericarps, as well as the shape and size of reproductive structures. Its ecology, conservation status and relationships with other allied Mediterranean species of the sect. Ferula are provided, as well as the analytical keys of the species belonging to the aforesaid section.

Nothodissotis (Melastomataceae), a new genus from Atlantic Central Africa, including the new species N. alenensis from Equatorial Guinea

2019

Based on morphological and phylogenetic evidence, a new genus of Melastomataceae (Melastomateae), Nothodissotis Veranso-Libalah & G.Kadereit, gen. nov., is described from Atlantic Central Africa. Nothodissotis is distinguished from other African Melastomateae genera by its calyx-lobes that are notched at apex and asymmetrical (vs. entire and symmetrical). Nothodissotis includes two species: the type species N.barteri (Hook.f.) Veranso-Libalah & G.Kadereit, comb. nov. (syn. Dissotisbarteri Hook.f.), and the new species N.alenensis Veranso-Libalah & O. Lachenaud, sp. nov., described and illustrated here. Both species are restricted to open vegetation on rock outcrops w…

Conservation Status of Some Peatbogs in Maramureş County

2016

AbstractPeat bogs and specially raised bogs are vulnerable ecosystems all over the world and they create refuges for some rare plant species. The aim of this paper is to provide information regarding the conservation status of five oligotrophic peat bogs situated in the volcanic mountains in the Oriental Chain of Carpathians, in Maramureș County. The studied peat bogs are: Tăul lui Dumitru (Dumitru Pond), Mlaștina Vlășinescu (Vlășinescu Peat bog), Iezeru Mare (Big Tarn), Tăul Chendroaiei (Chendroaiei Pond) and Tăul Negru (Black Pond), all of them have the status of nature reserve and under the IUCN categories they are included in category IV Habitat/Species Management Area (www.iucn.org, 20…

Helminth parasitizing <em>Iberolacerta cyreni</em> (Müller et Hellmich, 1937) from Gredos Mountains, Iberian Peninsula

2017

A survey of the helminth communities of a population of Iberolacerta cyreni (Müller et Hellmich, 1937), a small lizard endemic to Sistema Central (Iberian Peninsula), was conducted to determine the prevalence, abundance and species diversity of parasites of these reptiles. Four species of helminths were found, one trematode, Plagiorchis molini Lent et Freitas, 1940, one cestode, Nematotaenia tarentolae López-Neyra, 1944, and two nematodes, Skrjabinelazia sp. and Spauligodon carbonelli Roca & García-Adell, 1988. Helminth infracommunities of I. cireny showed very low values of abundance and species richness and diversity, being similar to other European lizards. The parasites found seem t…

Gobio Genus Species Integrated Management System – Târnava Rivers Study Case (Transylvania, Romania)

2019

Abstract The lotic habitats quality indicative congeners species Gobio gobio, Gobio kessleri and Gobio albipinnatus populations’ dynamic in time (2004-2019) and space revealed a decreasing trend in these rivers ecological status. The ADONIS:CE tool has been used to build a backing management system model, based on these indicative fish species habitat needs, indicators for favourable conservation status, pressures and threats. This management system implementation in the field will favour the amelioration of lotic habitats and the ecological status recovering of two of the local fish species of conservative interest (G. kessleri and G. albipinnatus).

Kali dodecanesicum (Chenopodiaceae, Salsoloideae) a new species from Greece

2015

Kali dodecanesicum, a new species from some islands (i.e. Rhodes, Kos and Nisyros) of the Dodecanese in the south-eastern Aegean (Greece), is described and illustrated. According to recent literature, Kali is treated as a distinct genus from the polyphyletic Salsola s.l., which includes several annual species. The new species is morphologically well separated from the other Kali taxa mainly for the shape of the fruiting perianth, showing closer relationships with Kali ponticum. Its ecological requirements, distribution, and conservation status are also examined, together with an analytic key of the Kali species occurring in the Mediterranean area.

A new species of Kali (Salsoloideae, Chenopodiaceae) from Sicily, supported by molecular analysis

2015

Nomenclatural and taxonomical considerations on Kali , a controversial genus recently segregated from the polyphyletic Salsola s. lat. ( Chenopodiaceae ), are provided. The Kali group includes annual plants with leaves ending in a spine and lacking hypodermis, having also a cortex alternate to longitudinal chlorenchymatous striae. The species belonging to this genus mainly have a paleotemperate distribution (Europe, Asia and North Africa), occurring as aliens in North America, Australia and South Africa. A new species collected on Mt. Etna (Sicily), and closely related to K. australe , is described and illustrated as K. basalticum Its morphological and molecular features, karyology (2n=54),…

A new species of Thilachium (Capparaceae) from the Analanjirofo Region, Madagascar

2023

Madagascar is a centre of speciation for the genus Thilachium Lour., which includes several species of small trees and shrubs occurring in a wide range of habitats. A new species of Thilachium, T. latifolium Fici, from the Analanjirofo Region of northeastern Madagascar is here described and illustrated. It is characterised by 1-foliolate leaves, leaf blades widely ovate or elliptic with shortly acuminate or acute apices, flowers in terminal, dense subumbels or corymbs, short pedicels and ellipsoid, ribbed fruit. The new species is related to T. madagascariense Fici, a species recently described from eastern Madagascar, differing in the wider, coriaceous leaves with shorter, mucronulate tip,…
