Bark anatomy of lianescent Bignoniaceae: a generic synopsis
Adansonia 45 (12)
Species with lianescent habit account for half of the diversity of Bignoniaceae. Recent molecular phylogenetic studies have provided the basis for new circumscriptions of entire liana lineages within tribes Bignonieae and Tecomeae s.s., where only monophyletic taxa are recognized. However, some clades remain without good morphological synapomorphies. In search of features of taxonomic potential, we collected, sectioned, and analyzed the bark of 83 lianescent species of the Bignoniaceae, covering all 20 genera from tribe Bignonieae currently recognized, plus three of the most widely cultivated lianas of Tecomeae s.s. Detailed bark descriptions are given to major lineages within both tribes, following their most recent phylogenetic hypotheses and classifications.
Neither fish nor fowl. Isotopic evidence of a plant-based diet in (captive?) brown bears from Roman Augusta Raurica, Switzerland
Anthropozoologica 58 (5)
In Roman times, the brown bear (Ursus arctos Linnaeus, 1758) was one of the most important hunted wild animal species. Bears were killed for e.g. their furs, their teeth and their meat. One of the reasons for catching bears alive was for their use in the context of public entertainment, i.e., animal hunts in amphitheatres. Bear bones from the Roman settlement of Augusta Raurica, NW Switzerland, attest the tradition of hunting (or trading?) bears in this part of the Roman Empire. Archaeozoological investigations of several complete bear skeletons from this site indicated that at least one bear was kept in captivity for some period.

Adansonia 45 (11)
Typification of three names in the genus Blumea DC. (Asteraceae) viz. B. solidaginoides (Poir.) DC., B. floresiana (Sch.Bip. ex Miq.) Boerlage and B. dregeanoides Sch.Bip. ex A.Rich. is discussed and lectotypes are designated.
Les premiers sauroptérygiens (Reptilia, Sauropterygia) découverts dans le Trias français par Charles Antoine Gaillardot et leur interprétation par Georges Cuvier
Geodiversitas 45 (8)
Charles Antoine Gaillardot (1774-1833), a former military doctor in the French army, who returned to his hometown of Lunéville (Meurthe-et-Moselle department, north-eastern France), was the first to report the presence of bones in the Upper Muschelkalk (Ladinian, Middle Triassic) of Rehainviller and Mont-sur-Meurthe (France). He communicated these specimens to Georges Cuvier (1769-1832) who described and illustrated them in the last volume of the new edition of his Recherches sur les ossemens fossiles published at the end of 1824. According to Cuvier, these bones were those of an unknown “saurian” exhibiting supposed affinities with crocodiles, ichthyosaurs, plesiosaurs and monitors (varans). Cuvier also thought he recognized the bones of a so-called “very large sea turtle”.
Woznikella triradiata n. gen., n. sp. – a new kannemeyeriiform dicynodont from the Late Triassic of northern Pangea and the global distribution of Triassic dicynodonts
Comptes Rendus Palevol 22 (16)
Despite nearly two centuries of intensive research of dicynodont diversity and distribution, the progress of the last two decades makes the early 21st century a dicynodont renaissance. Here we introduce Woznikella triradiata n. gen., n. sp., a Late Triassic European kannemeyeriiform with stahleckeriid affinities that may represent an early diverging lineage of that family, preceding its split into Placeriinae King, 1988 and Stahleckeriinae Lehman, 1961. Woznikella triradiata n. gen., n. sp. is distinguished from other dicynodonts by its autapomorphic, slender scapula with distinctly expanded dorsal and ventral parts, acromion directed anterodorsally, and inconspicuous scapular spine.
The Epiphytic Bryophyte Vegetation of Buxus sempervirens L. forests in the Fırtına Valley (Rize, Turkey)
Cryptogamie, Bryologie 44 (5)
The Fırtına Valley forests are of the 100 forests in the world whose conservation is a priority due to the natural old forests they have. In this study, the epiphytic bryophyte vegetation of the Buxus sempervirens L. forests located in the Fırtına Valley (Rize, Northern Turkey), which is one of the nine hotspots in Turkey and Turkey’s only boxwood forest, was investigated. The relevés taken from living tree trunks in 2020 were analyzed according to the Braun-Blanquet methodology, and ordinated and classified using the Detrended Correspondence Analysis (DECORANA) and the Two-Way Indicator Species Analysis (TWINSPAN). As a result of the analyses, Exsertotheco crispae-Allenielletum besseri ass. nov.
Fréquentations des réseaux karstiques profonds par Néanderthal. Nouveaux exemples à la grotte de Saint-Marcel (Ardèche, France)
Comptes Rendus Palevol 22 (15)
Saint-Marcel Cave, in the terminal part of the Ardèche Gorge, is a vast karstic network, and also a key Mousterian site close to the Rhône Valley. Numerous occupations dated between the last interglacial (MIS 5e) and the end of MIS 3/beginning of MIS 2 are well documented beneath the natural porch. Recently, two discoveries of Mousterian lithic industries in the entrance gallery, 150 and 500 m from the porch, have been uncovered. They attest to deep incursions by Neanderthals into very large galleries in the karst network, at considerable distances from the daylight zone. The association of these lithic industries with Pleistocene faunal assemblages, mainly from cave bear dens, suggests that Neanderthals exploited Ursidae.
The French Polynesian Atractocarpus Schltr. & K.Krause (Rubiaceae): circumscription of A. tahitensis and description of A. teamotuaitaui sp. nov., both microendemic and critically endangered species in the Society Islands
Adansonia 45 (10)
French Polynesia possesses the most eastward species of the genus Atractocarpus Schltr. & K.Krause in the Pacific Ocean. The genus was known from a single species in the Society Islands, Atractocarpus tahitensis (Nadeaud) Puttock, restricted to Tahiti and Raiatea. The species remained unseen there for more than a century. Field prospections from poorly explored altitudinal areas of Tahiti Nui allowed to find new populations of the species. Moreover, another taxon bearing very atypical features, including shortly petiolate and basally cordate leaves (vs long petiolate and basally attenuate leaves), is here recognized and described as a species new to science, Atractocarpus teamotuaitaui sp. nov., restricted to Tahiti’s peninsula (Tahiti Iti).
Phylogenetic analysis of the red algal tribe Ceramieae reveals multiple morphological homoplasies but defines new genera
Cryptogamie, Algologie 44 (2)
Despite the importance of morphological characters for classification, molecular data are now more widely used than morphology in phylogenetic reconstructions, particularly in studies of algae. The tribe Ceramieae C.Agardh ex Greville (Ceramiaceae) is a widespread, speciose, and morphologically diverse group of valuable red algae with many identified bioactives. We aimed to elucidate phylogenetic relationships in the tribe to delimit genera and provide a new classification. Generic delimitation is currently based on morphological characters, and there has been no overall reassessment of generic circumscriptions and evolutionary relationships using molecular data. We used three molecular markers (mitochondrial COI-5P, plastid rbcL and nuclear LSU).
First report of complete mitogenome for an Itarinae species (Orthoptera, Grylloidea) with phylogenetic analysis
Zoosystema 45 (8)
The subfamily Itarinae Shiraki, 1930 belongs to the cricket family Gryllidae Laicharting, 1781 based on morphology. However, there is no phylogenetic research on Itarinae and the relationships of Itarinae within Gryllidae remain to be solved. Mitochondrial genomes (mitogenomes) have been extensively used as markers to infer the phylogenetic relationships between some families in Orthoptera. Here, we reported the first complete mitogenome of subfamily Itarinae and the mitogenome features of Itara minor Chopard, 1925. The mitogenome of this species is 17342 bp which contains 37 genes (13 protein-coding genes, 2 ribosomal RNA and 22 transfer RNA) and a control region, and is conserved in structure as most of species in Gryllidae.
Cenozoic diversity and distribution of the mangrove- and mudflat-associated gastropod genus Terebralia Swainson, 1840 (Potamididae: Caenogastropoda) in Europe
Comptes Rendus Palevol 22 (14)
We analyse the distribution of the potamidid genus Terebralia Swainson, 1840 in the European fossil record (middle Eocene to Miocene). Extant Terebralia contains species restricted to mangroves and mudflats, rendering it a reliable element for detecting these coastal environments in the fossil record. Our contribution summarizes the European fossil record of this taxon and highlights the presence of this genus within coastal environments in the European realm. Distribution in the Cenozoic is interpreted based on ecological preferences, dispersal modes and climatic restrictions of recent species.
A small penguin cranium (Aves, Spheniscidae) from the Late Miocene of Bahía Inglesa Formation, Atacama Desert, Northern Chile
Comptes Rendus Palevol 22 (13)
A new cranium of penguin from the Late Miocene of the Bahía Inglesa Formation (Northern Chile) is described here. Specimen SGO.PV.22245 exhibits a unique combination of characters that suggests it belongs to a new species of either Eudypula Bonaparte, 1856, Spheniscus Brisson, 1760, or more probably to a more basal taxon related to them. The specimen is notably smaller than the fossil species of Spheniscus and more similar in size to the extant Spheniscus. The fossa glandulae nasalis narrows caudally, the crista nuchalis transversa and the crista temporalis are expanded like short wings, and a short crista nuchalis sagittalis connects with the rounded and cranially projected eminentia cerebellaris.
