The Mediterranean species of Hornera Lamouroux, 1821 (Bryozoa, Cyclostomata): reassessment of H. frondiculata (Lamarck, 1816) and description of H. mediterranea n. sp.
Zoosystema 42 (27)
Hornera Lamouroux, 1821, a genus which includes large, rigidly erect, ramified and highly calcified cancellate cyclostome species, is represented in the Mediterranean Sea by two species, H. frondiculata (Lamarck, 1816), the type species of the genus, and a species previously left unnamed or wrongly attributed to the northern H. lichenoides (Linnæus, 1758), and classed under this name as threatened in the Mediterranean (Barcelona Convention, Annex II).
The oldest erymnochelyine turtle skull, Ragechelus sahelica n. gen., n. sp., from the Iullemmeden basin, Upper Cretaceous of Africa, and the associated fauna in its geographical and geological context
Geodiversitas 42 (25)
We describe the skull of Ragechelus sahelica, n. gen., n. sp., a pleurodiran Pelomedusoides turtle, the oldest skull known of the Erymnochelyinae. The specimen comes from the surroundings of Indamane village, from a littoral late Maastrichtian level of the Iullemeden sedimentary basin (southwestern Niger, Africa). It is compared on the one hand to the members of the subfamily including remains from the neighboring Ibeceten locality, but from an underlying continental Senonian, and, on the other hand, particularly to the bothremydid Nigeremys gigantea (Bergounioux & Crouzel, 1968), from a littoral Maastrichtian level close to that of Indamane, and from a closer to Indamane locality than Ibeceten. The associated fauna is reviewed in its stratigraphic context.
Recording a syncarpy form and the first abnormal capsule lid worldwide in Byum dichotomum Hedw. population of Saudi Arabia
Cryptogamie, Bryologie 41 (16)
After quite a while, since 1950, from recording syncarpy “or double capsules” phenomena, the syncarpy is reported in the current study on a sporophyte of Byum dichotomum Hedw. In addition, we record a deformation case of a lid for one capsule carried by the same species to another individual of B. dichotomum population for the first time worldwide. Byum dichotomum was found growing on moist, shaded inclined land of Al-Shafa road, Taif Province in Saudi Arabia. The syncarpy phenomenon and the appearance of an abnormal lid have been discussed and illustrated.
Typification of three Iraqi endemic taxa of Centaurea L. (Asteraceae, Cardueae)
Adansonia 42 (15)
Three Iraqi endemic taxa of Centaurea L. (Asteraceae) are typified, namely Centaurea foveolata Blakelock, C. fusiformis Blakelock, and C. longipedunculata Sch. Bip. ex Boiss.
Création, hiérarchisation, énumération : l’ordonnancement du monde animal dans le chapitre XIII du Bundahišn
Anthropozoologica 55 (15)
The Late antique Zoroastrian texts have the marks of an interest in ordering the animal world. The Middle Persian text of the Bundahišn presents, in chapter XIII, a theoretical structure of order and an enumeration of animal species. The analysis of this structure, consisting of horizontal and vertical categorization lexems, such as the names of given species, invites us to think the way in which religious discourse and interest in the animal world are intertwined in the cosmogonic narrative. The formation of animal categorizations then depends on the Zoroastrian tradition and on the knowledge of the animal world in late antiquity, as well as on willingness for orderly enumeration, which is an important character of the Bundahišn.
Quelle biodiversité urbaine est observée sur les espaces verts, les friches et les cimetières ? Une illustration à Grenoble
Naturae 2020 (10)
The growth of human population has led to increasing pressures on ecosystems and biodiversity. Urban encroachment on natural habitats threaten biodiversity and urban life contributes to a disconnection with nature. One particular question arises in this context: what is the existing biodiversity in cities? A study was carried out through naturalist monitoring in the city of Grenoble (France) and its conurbation, a densely urbanised valley, strongly contrasting with the neighbouring agricultural or natural spaces. Three types of urban sites (recreational parks, wastelands and cemeteries) were compared on the one hand; on the other hand, impact of park management intensities on biodiversity was assessed.
Trophic position of some Late Devonian-Carboniferous (Mississippian) conodonts revealed on carbon organic matter isotope signatures: a case study of the East European basin
Geodiversitas 42 (24)
An isotopic investigation of organic matter of the Late Devonian-Carboniferous (Mississippian) conodont elements of various morphology was carried out. δ13Corg values of conodont elements measured in this study range from -32.6‰ to -22.4‰, with an average value of –26.1 ± 4.8‰. The study taxa represent four types of conodont apparatus, which differ one from another by morphology of P1 elements. In spite of apparently different morphology all the studied conodonts possess close δ13Corg values. Taxonomic control on the carbon isotope composition is insufficient as well. High consistency of the carbon isotope composition of conodont organic matter suggests that the Late Devonian and Carboniferous (Mississippian) conodonts occupied similar trophic levels.
An evaluation of the endemic bryophyte flora of Guadeloupe
Cryptogamie, Bryologie 41 (15)
The Guadeloupe archipelago has a rich bryophyte flora with 633 species, including 19 species considered endemic to Guadeloupe. Most of the endemic species are only known from type material and are of doubtful taxonomic status. An examination of the types and literature leads to the recognition of three confirmed endemic species in the Guadeloupe archipelago: Frullania trigona L.Clark, Jovet-Ast & Frye, Riccardia innovans (Steph.) Pagán and Trichosteleum glaucinum (Besch.) A.Jaeger. All three are very rare and only known from the type. Field searches to locate further populations were unsuccesful. The remaining “endemic” species are not restricted to Guadeloupe and most of them are synonyms of widely distributed taxa.
An Early Cretaceous theropod dinosaur from Brazil sheds light on the cranial evolution of the Abelisauridae
Comptes Rendus Palevol 19 (6)
Abelisaurid theropods dominated the predator role across Gondwana during the Late Cretaceous. They are characterized by highly reduced forelimbs and one of the most specialized cranial morphologies among carnivorous dinosaurs, exemplified by a broad skull, short rostrum, high occipital region, and highly kinetic intramandibular joint, suggestive of a specialized feeding strategy. Late Cretaceous abelisaurids are known from some remarkably complete taxa with well-preserved skulls. However, little is known about the pattern of character transformation that led to their highly modified condition because there are no well-preserved abelisaurids before the Late Cretaceous.
‘Retraction’ of taxonomic papers: the meaning of the word ‘issued’ and related ones in zoological nomenclature
Zoosystema 42 (26)
A basic reason for the diverging interpretations regarding the nomenclatural status of ‘retracted’ publications lies in different understandings of some ‘simple’ terms like ‘issued’, used in Article 8 of the Code but not defined in this text. After a discussion of the questions at stake, formal definitions of some of these terms are provided.
Morphological and molecular taxonomy of Pythium monoclinum Abrinbana, Abdollahz. & Badali, sp. nov., and P. iranense, sp. nov., from Iran
Cryptogamie, Mycologie 41 (11)
Two new species of Pythium Pringsheim isolated from soils of northwestern regions in Iran, are described: P. monoclinum Abrinbana, Abdollahz. & Badali, sp. nov., and P. iranense, sp. nov. Both species are morphologically distinct from all known species. Pythium monoclinum Abrinbana, Abdollahz. & Badali, sp. nov., is morphologically characterized by the presence of a swollen element in oogonial stalks below terminal oogonia, mostly monoclinous antheridia originating at various distances from the oogonia that occasionally arising from inflated part of oogonial stalk and, rarely production of peanut-shaped and double oospores.
Populations of a new morphotype of corrugate Lessonia Bory in the Beagle Channel, sub-Antarctic Magellanic ecoregion: a possible case of on-going speciation
Cryptogamie, Algologie 41 (11)
During a 2007 expedition dedicated to study kelp diversity within the Magellanic region, specimens of Lessonia Bory with corrugate, yellowish blades were found along the Beagle Channel. This type of corrugated Lessonia is uncommon, with exception of two species from New Zealand. Three possible hypotheses for its origin were explored in this study: an introduction of L. adamsiae Hay or L. corrugata Lucas from New Zealand by trans-oceanic dispersal; a hybridization between Chilean Lessonia species and Macrocystis pyrifera C.Agardh, particularly abundant in the region; or the existence of a new, undescribed species.
