Priorités de conservation des espèces en Auvergne : l’apport des Listes rouges régionales
Naturae 2020 (1)
Using subnational Red Lists from the former Auvergne region and available occurrence data, multi-group cross-analyses were carried out to provide a synthesis of the conservation status of species of Auvergne and to illustrate the main trends as well as the main issues for local biodiversity. The results show there are a large number of threatened and near threatened species, including more than half of amphibians, bryophytes and birds. The highest proportions of unknown species concern certain vertebrates (amphibians and mammals) and flora. There is a lack of public policy framework or regulatory statutes for more than 170 species listed under the ‘Data Deficient’ category and for as many endangered species.
New Pottiaceae genera to the moss flora of Saudi Arabia and the Arabian Peninsula
Cryptogamie, Bryologie 41 (1)
Hyophila Brid., Leptophascum (Müll.Hal.) J.Guerra & M.J.Cano and Plaubelia Brid. are new genera to the bryoflora of Saudi Arabia while the last two genera are new to the Arabian Peninsula. All these genera are represented by one species each namely; Hyophila baginsensis Müll.Hal., Leptophascum leptophyllum (Müll.Hal.) J.Guerra & M.J.Cano and Plaubelia involuta (Magill) R.H.Zander. Hyophila baginsensis is a new record to the bryoflora of Asia continent. The new recorded species are described and illustrated. Their sites, habitats, distribution, elements and some floristic remarks are given.
The exploitation of molluscs and other invertebrates in Alexandria (Egypt) from the Hellenistic period to Late Antiquity: food, usage, and trade
Anthropozoologica 55 (1)
A number of archaeological salvage excavations conducted in Alexandria (Lower Egypt) by the Centre d’Études alexandrines have provided a corpus of around 2000 fragments of marine, freshwater and terrestrial invertebrates. These archeomalacological remains come from several occupation layers of the same district within the town, the Brucheion, dating from the end of the 4th century BC until the 6th century AD. After macroscopic observations and through a binocular microscope, the analysis of the malacofauna vestiges has provided previously unknown information regarding the exploitation of the aquatic environment by Alexandrians during antiquity. In addition, some residues of mineral material preserved on the shells have been analysed under a scanning electron microscope (SEM).
A review of the genus Coccoglypta Pilsbry, 1895 (Gastropoda: Pulmonata: Camaenidae)
Zoosystema 41 (29)So far, the genus Coccoglypta Pilsbry, 1895 consisted of two species and two subspecies as follows: C. pinchoniana (Heude, 1886) type species of the genus, C. scrobiculata scrobiculata (Gredler, 1885) and C. scrobiculata hupeiana (Gredler, 1887). We examined shells and genitalia, and performed molecular analyses of Coccoglypta specimens from Sichuan Province, which have revealed the existence of a yet undescribed species (Coccoglypta liui Páll-Gergely, n. sp.). Based on conchological information, Coccoglypta scrobiculata does not belong to the Camaenidae Pilsbry, 1895 s.l., but to the Ariophantidae Godwin-Austen, 1883.
Liste de référence fonctionnelle et annotée des Mollusques continentaux (Mollusca : Gastropoda & Bivalvia) du Grand-Est (France)
Naturae 2019 (11)
Collaborative platforms for biodiversity observation, coupled with taxonomic databases, now allow to automatically generate species checklists and/or distribution atlases at various temporal and geographical scales. We assess here the reliability of such automatically generated species checklist using non-marine molluscs from the Grand-Est region as a model. The assessed primary list was generated from the extraction filter of platform of the SINP (Système d’Information sur la Nature et les Paysages) and its associated taxonomic framework TAXREF. This primary list was compared with the taxonomical list independently elaborated by the authors of the present article. We show that the recovery rate between the primary list, citing 233 terminal taxa, and our list is about 90%.
New remains of kollpaniine “condylarths” (Panameriungulata) from the early Palaeocene of Bolivia shed light on hypocone origins and molar proportions among ungulate-like placentals
Geodiversitas 41 (25)
The description of new specimens of kollpaniines “condylarths” from Tiupampa (early Palaeocene of Bolivia) represents a significant addition to the knowledge of the earliest fauna of South American ungulates. Several partial mandibles and maxillae of Molinodus suarezi and Simoclaenus sylvaticus are described. The morphology of the lower premolars of Molinodus, being associated to lower molars, is established and a previous referral of an isolated p4 is rejected. A maxilla of Simoclaenus reveals the morphology of the so far unknown P1-4 of this taxon and allows a discussion on the development of the protocone in Palaeocene “condylarths”.
A complete description and conservation assessment of Riella affinis Howe & Underwood (Riellaceae, Sphaerocarpales) new to continental Europe
Cryptogamie, Bryologie 40 (23)
Riella affinis Howe & Underwood is a rare species that is thus far known from eight populations worldwide. Only half of these were recorded in the last 50 years and none were recollected since first reported. Study of a Spanish population of R. cossoniana Trab., recorded in 2002 from Las Lomas, Malaga province, revealed that it belongs to R. affinis. The correct identity of the populations, which had not been available for study, was already suggested by reproductive and ecological characteristics of the plants mentioned in the original publication. The three main lagoons from the Las Lomas endorheic system, where the plants had been recorded, were sampled and living plants of R.
Duckweeds (Araceae: Lemnoideae) growing on wet, vertical rocks behind a waterfall in Costa Rica, with a new country record of Wolffiella oblonga (Phil.) Hegelm.
Adansonia 41 (15)
A large colony of duckweeds (Araceae: Lemnoideae) grows on the constantly wet, vertical wall of the rock shelter behind the Llanos de Cortés waterfall of the Potrero River, Guanacaste province, Costa Rica, the first such case ever documented. Its unique hygropetric environment is described. The colony covers several square meters distributed in several different patches, and consists almost entirely of Wolffiella oblonga (Phil.) Hegelm., with much fewer individuals of Lemna valdiviana Phil. and L. aequinoctialis Welw. This also constitutes the first case of the genus Wolffiella Hegelm. growing in a hygropetric manner (an extremely rare condition for duckweeds) and the first record of W. oblonga in Costa Rica.
The Oligocene and Miocene fossil lizards (Reptilia, Squamata) of Central Mongolia
Geodiversitas 41 (24)
Lizard material from the early Oligocene and early and late Miocene of the Valley of Lakes, Central Mongolia is described. Besides the Oligocene fossorial squamate published elsewere, the material can be allocated to several major clades: Agamidae, Lacertidae and Anguidae (Glyptosaurinae). The presence of Pseudotinosaurus Alifanov, 1991 in early and late Rupelian localities shows that this taxon has a continuous history in this area from the Eocene to the Oligocene. The same is true for the clade Glyptosaurinae, represented by isolated osteoderms in the early Oligocene locality Hsanda Gol. This might suggest that the Eocene-Oligocene transition did not have such a strong or rapid impact in East Asia, in contrast to the Grande Coupure in Europe, at least among some lizard clades.
Novelties in the hornwort flora of Croatia and Southeast Europe
Cryptogamie, Bryologie 40 (22)
Hornworts are globally the least diverse bryophyte group with respect to species number, with only eight species known from Europe. As for Croatia, only two species are listed in the available literature, with most recent record being more than 85 years old. Our study carried out in Central Croatia identified three new species for the hornwort flora, including two new genera – Notothylas Sull. ex. A. Gray and Anthoceros L. Our finding of very rare Natura 2000 species Notothylas orbicularis (Schwein.) A. Gray, reported hitherto only from four Central European countries, is the first in Southeast Europe and the southernmost in Europe.
Three new species of Ulnaria (Kützing) Compère (Bacillariophyta) from China, with reference to the fine structure of their valvocopula
Cryptogamie, Algologie 40 (11)
Three new species of Ulnaria (Kützing) Compère are described based on light and scanning electric microscopy observations. Ulnaria oxybiseriata D.M. Williams & Bing Liu, sp. nov., has linear-lanceolate to lanceolate valves with apiculate and produced ends, biseriate striae, and a central area mostly forming an incomplete fascia surrounded by shortened striae on one side.
