Rindifilum ramosum gen. nov., sp. nov., a new freshwater genus within the Ulvales (Ulvophyceae, Chlorophyta)
Cryptogamie, Algologie 43 (8)
The present paper provides a phylogenetic and morphological study of two strains that turn out to represent a new genus and species, Rindifilum ramosum gen. nov., sp. nov., within the family Ctenocladiaceae (Ulvales). Rindifilum ramosum gen. nov., sp. nov. grows in association with the lichenized ascomycetes genus Verrucaria Schrader. Phylogenetic reconstructions based on the rbcL, 18S rRNA and tufA genes showed that the investigated strains belonged to a lineage distinct from those sequenced so far. Moreover, comparisons based on morphological observations revealed no differences between the two strains. The newly genus Rindifilum gen. nov.
Parabintoniella papierae n. gen., n. sp., a new Triassic representative of the Bintoniellidae, a poorly known extinct family of Orthoptera (Insecta)
Geodiversitas 44 (21)
A new species of stem-Orthoptera, Parabintoniella papierae n. gen., n. sp., is described from the Grès à Voltzia Formation (Middle Triassic) of the Vosges (France). This new species, represented by two forewings, can be confidently assigned to the Mesozoic family Bintoniellidae, but it differs from the known representatives by its unique combination of character states, including a simple MA and numerous branches of CuA+CuPaα. The size difference between the two forewings is probably due to sexual dimorphism. This discovery complements our knowledge of the disparity of the various stem-groups of Orthoptera which emerged during the Permian and became extinct during the Mesozoic.
La prairie permanente non pâturée : un habitat souvent délaissé pour la conservation des Squamates du bocage
Naturae 2022 (10)
Best habitat management practices for the conservation of terrestrial Squamate reptiles mainly focus on edge habitats, and often neglect open habitats such as meadows. Monitoring of a community of Squamate reptiles during a whole year took place within the Loire-Atlantique department through direct visual observation and by searching under a network of coverboards positioned on the edges and centre of an ungrazed permanent meadow. The analysis of data showed that there are discrepancies in the exploration of ungrazed meadow according to species, mode of thermoregulation, time of year, and age of individuals. Lacertids tend to stay in the vicinity of the hedges, while snakes and slow worm display a more exploratory behaviour and are found away from the hedges as time of year advances.
The maximum and the minimum: two new species of Tovomita Aubl. (Clusiaceae) from the Guiana Shield with an unusual number of stamens
Adansonia 44 (16)
Two new species of Tovomita Aubl. (Clusiaceae) from the Guiana Shield are described and illustrated. Tovomita maxima Molino & J.Engel, sp. nov., known from French Guiana, Guyana and Brazil, stands out by its large size (up to 30 m high), large leaves with eucamptodromous venation, calyptrate bracteoles and an unusual variation in the number of stamens (74-145). Tovomita saulensis J.Engel & Molino, sp. nov., probably endemic to central French Guiana, is an understory tree with small leaves with brochidodromous venation and flowers with few stamens (9-15). Illustrations, descriptions, photographs in vivo, a preliminary conservation status, distribution map and comments on the morphology of related species are provided.
DNA analysis of the lectotype specimen of Ulva nematoidea Bory (Ulvaceae, Chlorophyta) determines its synonymy with Ulva lactuca L.
Cryptogamie, Algologie 43 (7)
Ulva nematoidea Bory is a currently accepted species distributed in the south eastern Pacific Ocean from Mexico to Chile. Its identity however remains unknown because no DNA sequences have been obtained from the type specimen. To determine its identity and taxonomic status, we performed high-throughput sequencing on a fragment of the lectotype specimen of U. nematoidea. Genetic analyses of the rbcL, tufA and nuclear ITS DNA found that U. nematoidea is identical in sequence to U. lactuca L. These results indicate that U. nematoidea is a synonym of U. lactuca and further highlight the need for sequencing additional type specimens of Ulva L.
A cool-water bryozoan association from the La Pola Formation (Sandbian, Ordovician) of Argentine Precordillera
Geodiversitas 44 (20)
Nineteen bryozoan species belonging to 18 genera are described from the La Pola Formation (Sandbian, Upper Ordovician) of Argentine Precordillera. Two trepostome genera each with one new species, respectively, are new: Albardonia bifoliata n. gen., n. sp. and Argentinopora robusta n. gen., n. sp. Five more species are new: a cystoporate Xenotrypa argentinensis n. sp., two trepostomes Heterotrypa enodis n. sp. and Nicholsonella spinigera n. sp., as well as two ptilodictyines Pseudostictoporella simplex n. sp. and Chazydictya ornata n. sp. The studied fauna shows some connection with Laurentia and Baltica on the species level and is similar to Siberia on the generic level.
Fusulinid Biostratigraphy of the Moscovian-Lower Kasimovian of Hadim Nappe, Central Taurides, southern Turkey
Geodiversitas 44 (19)
The Hadim Nappe which is one of the allochthonous tectonic units in the Tauride Belt includes continuous stratigraphic successions from Middle(?)-Late Devonian to Late Cretaceous. The well exposed successions of the Moscovian to lower Kasimovian are selected for fusulinid biostratigraphy along three sections (Yassıpınar, Gölbelen and Bademli) in the Central Taurides. The Lower-Middle Pennsylvanian boundary was determined by the first appearance datum of the Aljutovella aljutovica (Rauzer-Chernousova, 1938) and Solovievaia ovata ovata (Rauzer-Chernousova, 1938).
Bryophytes from Martírios-Andorinhas Mountain Ridge, a highly impacted Amazonia-Cerrado transition zone in southeastern Pará, Brazil
Cryptogamie, Bryologie 43 (7)
The Martírios-Andorinhas Mountain Ridge, in southeastern Pará, is located in a transition zone between two important biomes in Tropical America, Amazonia and the Brazilian Cerrado. The aim of this study was to inventory the bryophyte flora in different vegetation formations of the Martírios-Andorinhas Mountain Ridge, as a contribution to the evaluation of the environmental conservation status of the area. A total of 1784 specimens (1093 of mosses, 691 of liverworts) were gathered, with a prevalence of mosses over liverworts. In terms of species richness, however, liverworts (65 spp.) were as diverse as mosses (65). The number of specimens was higher in secondary forest (799), followed by gallery forest (670), riparian forest (208), and savanna (107).
Les déplacements des espèces volantes : vers la mise en œuvre d’une « Trame aérienne » dans le cadre de la politique Trame verte et bleue ?
Naturae 2022 (9)
While many animals use the airspace, human activities also occupy this space significantly. In this article we consider four types of obstacles – aircrafts, buildings, wind turbines and power lines – to illustrate their impacts on birds, bats and insects. Litterature shows that these airborne obstacles cause mortality through collisions, electrocutions and barotrauma, in addition to generating disturbance and habitat loss/fragmentation. However, the quantification of these problems remains highly variable depending on the obstacles and species, and is generally poorly known in France (except for aircraft and, to a lesser extent, wind turbines). We then present various management measures that are already being implemented or tested to reduce these impacts.
The type specimens of extant asteroids (Echinodermata) in the Muséum national d’Histoire naturelle of Paris
Zoosystema 44 (11)
Since its foundation in 1793, type specimens of 441 asteroid species and subspecies have been deposited in the Muséum national d’Histoire naturelle of Paris. The annotated catalogue of all these taxa is drawn up including species whose type material could not be found in the collection. Today the Paris museum houses 1011 asteroid type specimens representing 398 nominal species and subspecies, most of which were described by Lamarck (1816), Müller & Troschel (1842), Perrier (between 1869 and 1896) and Koehler (between 1895 and 1923). Though originating worldwide, species coming from the Atlantic and Indo-West Pacific Oceans, and Antarctic waters are more numerous.
Quantifying and interpreting nestedness of bryophytes in the Zhoushan Archipelago, China
Cryptogamie, Bryologie 43 (6)
The distribution data of 18 categories (including 446 species) of bryophytes in 66 islands of the Zhoushan Archipelago, China were complied. By using the matrix temperature and the NODF metrics under six null models, we evaluated their nestedness levels and explored possible mechanisms to form nested distribution with partial Spearman correlation and the random placement model.
Une révision de Dendrobium Sw. sect. Rhizobium Lindl. en Nouvelle-Calédonie
Adansonia 44 (15)
Dendrobium Sw. sect. Rhizobium Lindl. is revised and illustrated for New Caledonia. This section consists of three species for the territory: Dendrobium bowmanii Benth, D. casuarinae Schltr. and D. vagans Schltr. The latter species, reported in 1981 in the Province Sud, has been rediscovered. It is also mentioned for the first time in the Province des Îles Loyauté. Lectotypes of D. bowmanii, D. seemannii L.O. Williams (syn. of D. vagans) and D. casuarinae are designated. The IUCN status of the three species is proposed. Identification keys in French and English are given.
