Parasorex depereti (Crochet, 1986) (Lipotyphla, Mammalia), from the Upper Messinian (MN13) fissure filling of Brisighella (Faenza, Northern Apennine,…
2013
A large-sized species of Parasorex is rather common in the MN13 mammal assemblages from the uppermost Messinian sandy - marly fissure fillings within the Gessoso Solfifera Formation at Brisighella (Northern Apennine). This erinaceid had been originally classified as Galerix sp. in the first papers on the Brisighella fauna. Later on, it was described in detail in an unpublished dissertation by Fanfani (1999) who referred it to Galerix depereti. Unfortunately, the study remained virtually unknown to the scientific community. Hoek Ostende (2001) included G. depereti in the genus Parasorex, while Ziegler (2005) accommodated it in Schizogalerix. Hoek Ostende’s (2001) opinion is followed here. Pa…
Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 8
2019
The paper presents new records of 24 vascular plant species from 11 Eurasian countries. One taxon (Orobanche laxissima) is reported from Armenia ; one (Epipactis condensata) from Azerbaijan ; two (Phragmites americanus, Polygala multicaulis) from Belarus ; one (Stipa caucasica) from Egypt ; one (Puccinellia hauptiana) from Kyrgyzstan ; three (Aquilegia xinjiangensis, Geranium saxatile, Ranunculus songaricus) from Mongolia ; one (Stipa roborowskyi) from Pakistan ; three (Echinochloa muricata, Erigeron acris subsp. podolicus, Hypericum majus) from Poland ; six from Russia, whereof one (Zanthoxylum armatum) from the European part of Russia and five (Chaerophyllum aureum, Elsholtzia densa, Poa …
Diversity of leaf katydids (Orthoptera: Tettigoniidae: Phaneropterinae) of Dzanga-Ndoki National Park, Central African Republic, with selected record…
2013
Forty-four species of Phaneropterinae are recorded from Dzanga-Ndoki National Park in the Central African Republic. Eight species collected within the park are described as new to science: Phlaurocentrum morettoi n. sp., P. paratuberosum n. sp., P. elegans n. sp., Myllocentrum raggei n. sp., Poreuomena sanghensis n. sp., Cestromoecha longicerca n. sp., C. magnicerca n. sp., and Goetia purpurea n. sp. An additional new species from Guinea is described from specimens preserved in the Museo Nacional de Ciencias Naturales of Madrid, Poreuomena huxleyi n. sp. Eurycorypha stylata Stål, 1873 is recorded for the first time from Burkina Faso and Brycoptera lobata Ragge, 1981 from Ivory Coast. The fo…
Kretzoiarctos gen. nov., the oldest member of the giant panda clade
2012
The phylogenetic position of the giant panda, Ailuropoda melanoleuca (Carnivora: Ursidae: Ailuropodinae), has been one of the most hotly debated topics by mammalian biologists and paleontologists during the last century. Based on molecular data, it is currently recognized as a true ursid, sister-taxon of the remaining extant bears, from which it would have diverged by the Early Miocene. However, from a paleobiogeographic and chronological perspective, the origin of the giant panda lineage has remained elusive due to the scarcity of the available Miocene fossil record. Until recently, the genus Ailurarctos from the Late Miocene of China (ca. 8–7 mya) was recognized as the oldest undoubted me…
Genetic and Ecotypic Differentiation in a Californian Plant Polyploid Complex (Grindelia, Asteraceae)
2014
Studies of ecotypic differentiation in the California Floristic Province have contributed greatly to plant evolutionary biology since the pioneering work of Clausen, Keck, and Hiesey. The extent of gene flow and genetic differentiation across interfertile ecotypes that span major habitats in the California Floristic Province is understudied, however, and is important for understanding the prospects for local adaptation to evolve or persist in the face of potential gene flow across populations in different ecological settings. We used microsatellite data to examine local differentiation in one of these lineages, the Pacific Coast polyploid complex of the plant genus Grindelia (Asteraceae). W…
PESI - a taxonomic backbone for Europe
2015
Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations, however, presents a serious challenge for end-users of taxonomic concepts. Users need standardised and continuously harmonised taxonomic reference systems, as well as highquality and complete taxonomic data sets, but these are generally lacking for nonspecialists. The solution is in dynamic, expertly curated web-based taxonomic tools. The Pan-European Species-directories Infrastructure (PESI) worked to solve this key issue by providing a taxonomic e-infrastructure for Europe. It strengthened the relevant social (…
Fauna Europaea: Diptera – Brachycera
2015
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all extant multicellular European terrestrial and freshwater animals and their geographical distribution at the level of countries and major islands (east of the Urals and excluding the Caucasus region). The Fauna Europaea project comprises about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. Fauna Europaea represents a huge effort by more than 400 contributing taxonomic specialists throughout Europe and is a unique (standard) reference suitable for many user c…
Allium paniculatum L., una specie critica ed erroneamente interpretata della flora europea
2010
Dalle indagini morfologiche e cariologiche condotte è emerso che Allium paniculatum è una specie ben differenziata dagli altri taxa della sez. Codonoprasum, con corredo cromosomico poliploide, esaploide o triploide, probabilmente originatosi in seguito all’adattamento ad ambienti sinantropici in territori con bioclima marcatamente mesico, come si desume dalle esigenze ecologiche, dal periodo di fioritura estivo e dalla distribuzione geografica.
Flora d'Italia
2017
This second edition of the Flora of Italy, complemented by the Digital Flora of Italy, summarizes the results of the botanical exploration in Italy during the last two hundred years. Italy is not only a beautiful country of extraordinary landscapes, rich environments, valleys and mountains along the whole Apennine Peninsula, in its centre the Eternal City and from north to south filled with many towns with incomparable art treasures. Placed in the mid of the Mediterranean Sea, Italy has also an astoundingly rich flora spreading from the shores to the highest mountains, with floristic environmental hotspots in the Alps (Dolomites, Mt. Baldo, Maritime Alps), along the Tyrrhenian coast, and on…
