Quelles trajectoires de réhabilitation pour la décharge de l’Île d’Ouessant (29) ? Retour sur dix années de recherche-action
Naturae 2021 (22)
In 2009, the study was launched prior to the closure of the Penn ar Roc’h landfill, surrounded by grasslands and heathlands with high coastal cliffs. Discussions between the engineering consultant in charge of the environmental study and academics from the University of Brest carrying out research on ecological restoration led to the launch of the design of an ecological engineering experiment (heath litter transfers and lawn mowing). During the REVER 2 seminar in Brest in 2010, a visit to the landfill site was carried out just before the ecological operations to benefit from the expertise of the participating researchers and practitioners.
Notes on the bryophytes of Madagascar 5: new records from old collections
Cryptogamie, Bryologie 42 (15)
Investigations into the bryophyte flora of Madagascar as part of the MadBryo project, show that five moss genera (Actinodontium Schwägr., Aulacopilum Wilson, Forsstroemia Lindb., Haplohymenium Dozy & Molk., and Herzogiella Broth.) are new for the island. For three additional taxa we clarify the correct name to use for Malagasy specimens. Ectropothecium perrieri Thér. is placed in synonymy with Herzogiella cylindricarpa (Cardot) Z.Iwats. and Lepidopilum diversifolium Renauld & Cardot is reduced to a synonym of Thamniopsis utacamundiana (Mont.) W.R.Buck. These particular cases highlight the hidden diversity lurking within underutilized natural history collections.
From fin rays to DNA: supplementary morphological and molecular data to identify Mormyrus subundulatus Roberts, 1989 (Pisces: Mormyridae) from the Bandama River in Côte d’Ivoire
Zoosystema 43 (27)
The genus Mormyrus Linnaeus, 1758 has been well studied in western Africa where five species are currently recognized. Mormyrus subundulatus Roberts, 1989 was described in 1989, and, although morphologically and genetically close to Mormyrus rume Valenciennes, 1847, is still considered by the most recent studies as a distinct species. It is endemic to the Côte d’Ivoire and Ghana River systems. It was historically recorded from only three locations but is today very likely extirpated from one of them and threatened in the remaining two. It is categorized as “Vulnerable B1ab(iii)” by the IUCN Red List (Dankwa 2020).
Comparative floral anatomy of some species of Brassicaceae and its taxonomic significance
Adansonia 43 (20)
The diversity of the floral characters in 25 species of Brassicaceae representing seven tribes was studied through tracing their floral organs vascularization. The aim of the present study is to explore the contribution of the micro-floral characters in understanding the relationships among the studied species of Brassicaceae as well as the evolutionary trends in calyx, corolla, androecium and gynoecium. It was concluded that the vascularization of sepals, petals, stamens, nectaries and carpels was considered diagnostic and reliable characters at the specific level. The reduction and presence of vascular complexes was found to be at the top of the floral evolutionary trends.
Garm Roud 2, Iran: bladelet production and cultural features of a key Upper Palaeolithic site south of the Caspian Sea
Comptes Rendus Palevol 20 (40)
For more than twenty years, Iran has focused a great deal of research on the emergence and development of Upper Palaeolithic industries. South of the Caspian Sea, the site of Garm Roud 2, dated to 33878 ± 3300 Cal BP, is one of the few sites, with Mirak, to have yielded stratified evidence of occupation during this period. This paper presents the results of the typo-technological analysis of the lithic assemblage collected during the 2006 to 2008 excavation campaigns. The focus here is on a production of straight and twisted bladelets. Very few similarities have appeared between this assemblage and those from sites in the Zagros and the rest of Iran, which are generally older (about 35 to 40 000 Cal BP).
Saxicolous lichens in the semi-arid Caatinga in Brazil show substratum shifts
Cryptogamie, Mycologie 42 (11)
Saxicolous lichens were investigated for the first time in the southern reaches of the Caatinga biome in Sergipe, NE Brazil. Only 20 species could be identified, and three more are described as new to science: Cresponea quinqueseptata Aptroot & M.Cáceres, sp. nov. with 5-septate ascospores and yellow pruinose discs; Fulgogasparrea intensa Aptroot & M.Cáceres, sp. nov. with a cinnabar red, appressed thallus with marginally elongated lobes; and Peltula nigrotestudinea Aptroot & M. Cáceres, sp. nov. with flat, black, isolated areoles. A number of substrate shifts was observed: 1) The new species of Peltula Nyl.
Five new species of freshwater crabs of the genera Ghatiana Pati & Sharma, 2014 and Sahyadriana Pati & Thackeray, 2018 from India (Decapoda: Brachyura: Gecarcinucidae)
Zoosystema 43 (26)
We recognize two new species of Ghatiana Pati & Sharma, 2014, and three new species of Sahyadriana Pati & Thackeray, 2018, from the Western Ghats of India. Ghatiana durrelli n. sp. is characterized mainly by the proportionately narrower adult carapace, the relatively broader male pleonal somite 6, and the relatively stouter terminal segment of the male first gonopod. Ghatiana rouxi n. sp. is differentiated from congeners by its proportionately narrower adult carapace with the gently convex lateral margins. Sahyadriana inopinata n. sp.
New sperm whale remains from the late Miocene of the North Sea and a revised family attribution for the small crown physeteroid Thalassocetus Abel, 1905
Comptes Rendus Palevol 20 (39)
In spite of a continuously expanding physeteroid fossil record, our understanding of the origin and early radiation of the two modern sperm whale families Kogiidae Gill, 1871 (including the pygmy and dwarf sperm whales, Kogia spp.) and Physeteridae Gray, 1821 (including the great sperm whale, Physeter Linnaeus, 1758) remains limited, especially due to the poorly resolved phylogenetic relationships of a number of extinct species. Among those, based on fragmentary cranial material from the late early to middle Miocene of Antwerp (Belgium, North Sea basin), the small-sized Thalassocetus antwerpiensis Abel, 1905 has been recognized for some time as the earliest branching kogiid.
Les porcs « long châssis » : le péril des mariages ? Comprendre les transformations du bestiaire dotal du Cameroun méridional
Anthropozoologica 56 (14)
The pig in its “long frame” range, that is to say as big as possible, is now in great demand in the bridewealth offerings among the Beti of Cameroon. This change is linked to the popularization of pig breeding. But the analogy between the pig’s reproductive capacity and the fertility wished to the bride and groom also need to be taken into account, for fertility is being the best one can address to them. Moreover, the opinion argues the witchcraft neutrality of the pig, an unhorned animal. However, the principle of the luxuriance of the bridewealth gifts induces families to demand even ten pigs. This implies a huge financial bleeding for the son-in-law. In addition to the recriminations it provokes, this situation blocks and disintegrates marriage plans.
New lichen species and records from the Chapada dos Guimarães, Mato Grosso, Brazil
Cryptogamie, Mycologie 42 (10)
Three species of lichens are described as new from the Chapada dos Guimarães in Mato Grosso (Brazil): Astrothelium muriconicum Aptroot & M.F. Souza, sp. nov. which is the first species in the core group of the genus, the A. conicum-group, with muriform ascospores; Gassicurtia lopesiana M.F.Souza & Aptroot, sp. nov. which is characterized by red apothecium margins and lichexanthone in the thallus; and G. pruinosa M.F. Souza & Aptroot, sp. nov. which has brown pruinose, UV+ green discs and less red pigmantation. A further 191 species are reported new to the state Mato Grosso, 14 of which are first reports from Brazil.
Évaluer la qualité des boisements riverains avec l’Indice de Biodiversité et de Connectivité des Ripisylves (IBCR) : une étude de cas avec les communautés d’oiseaux
Naturae 2021 (21)
In order to assess the carrying capacity of riparian forest stands for biodiversity, we propose a new index that takes into account the longitudinal and cross-sectional dimensions of the hydrosystem : the Index of Biodiversity and Connectivity for Riparian forests (IBCR). Consisting of 15 factors that provide information on criteria related to the stand attributs and its management, the surrounding context, disturbance/pressure and connectivity, the IBCR is a new tool that provides river managers with concrete elements to quickly diagnose the ecological status of riparian forest stands and guide management for the conservation of the biodiversity associated with these linear forests.
The publication date, onomatophore and onymotope of Emoia cyanura (Squamata: Scincidae)
Zoosystema 43 (25)
The publication date, availability and onymotope of the nomen Scincus cyanurus are assessed. The nomen was validly published by Lesson in 1830 and is based on a holophoront, probably from the island of Tahiti. Elements allowing the identification of the nomina cited in the synonymy of Scincus cyanurus are given. Eumeces lessonii Duméril & Bibron, 1839 is a replacement name of this nomen (alloneonym) and Emoia pheonura Ineich, 1987 is a subjective synonym (doxisonym) whereas the nomina Tiliqua lessonii Cocteau and Tiliqua kienerii Cocteau are unavailable as the part of the work of Cocteau proposing these nomina has not been published.
