Molecular analyses reveal the presence of Corynecladia J.Agardh (Rhodophyta, Rhodomelaceae) in the Mediterranean Sea with two new species, C. millarii sp. nov. and C. mediterranea sp. nov.
Cryptogamie, Algologie 45 (2)
The findings of this study expanded the geographic distribution of the genus Corynecladia J.Agardh, thought to be endemic to Australia. It is recorded for the first time as present in Europe, with two newly proposed species: C. millarii sp. nov. and C. mediterranea sp. nov. New collections belonging to the Laurencia complex were sampled from the Sicilian coasts of Italy. Examination of this material was carried out using both morphological comparisons and phylogenetic analyses of chloroplast (rbcL) and mitochondrial (COI-5P) nucleotide sequences. The resulting phylogenetic trees divided the Mediterranean specimens into two supported, separate branches, within the genus Corynecladia.
Geographic differentiation in the freshwater crab Potamon persicum Pretzmann, 1962 (Decapoda, Potamidae) in the Zagros Mountains: evidence from morphometry
Zoosystema 46 (4)
The freshwater crab Potamon persicum Pretzmann, 1962 in Iran is distributed along the western Alborz Mountains, its range extending southeast through the whole Zagros Mountains. We expected a high geographic differentiation within Potamon persicum between the main drainage systems in the region (Khalij Fars-Oman, Markazi and Urmia basins). To test this hypothesis, we conducted conventional morphometric and geometric-morphometric analyses. Comparison of males and females between populations of three main drainage systems showed significant differences of eleven traits. We also detected significant sex-specific differences among the three main drainage systems.
A methodology for skull reconstruction
Comptes Rendus Palevol 23 (9)
The reconstruction process of the skull and skeleton represents a critical step in the study of fossil vertebrates and is often responsible for how the evolutionary history of a taxon is interpreted. It is also an important step in any test of the researcher’s understanding of the anatomy of the fossil. Even so, there is no recognized method for its completion, leaving the actual process to the individual undertaking the investigation. While this is often accomplished in an appropriate manner, there remains extensive room for error.
Observer le comportement animal dans l’Antiquité – Induction des protocoles à partir des pratiques actuelles en écologie comportementale
Anthropozoologica 59 (2)
Historians of thought often interpret ancient discourse, including in natural sciences, as being influenced by ideological stances. In response to this intellectual bias, we believe it would be valuable to take the risk of relying on experiential evidence and cumulative observation when considering ancient natural history as a tradition. To put this approach to the test, which assumes a different origin of naturalist knowledge, we scrutinize Aristotle’s descriptions of the behavior of two groups of birds, namely the swallow and the partridge, primarily found in books VIII and IX of the History of Animals.
First report in the fossil record of a shark tooth embedded in a pinniped bone
Comptes Rendus Palevol 23 (8)
There are now many examples in the fossil record of shark bite marks preserved on biogenic materials including coprolites, ammonoids, sea star ossicles, an echinoid, and bone and calcified cartilage. These exceptional fossils document evidence of exploratory behavior, active predation, and/or scavenging. However, only a small subset report on the presence of shark teeth embedded in fossilized bone or cartilage. Although a few shark tooth-marked seal bones are known from the fossil record, no direct evidence of predation or scavenging in the form of a shark tooth embedded in a fossil seal bone has yet been documented.
A new monachine seal (Monachinae, Phocidae, Mammalia) from the Miocene of Cerro La Bruja (Ica department, Peru)
Geodiversitas 46 (3)
In the present study, we present a new monachine phocid, Magophoca brevirostris n. gen., n. sp., the fifth monachine described from the Pisco Formation (Peru). Coming from the Cerro la Bruja level at the locality of the same name, Magophoca n. gen. is the geologically oldest known seal from the Neogene of the southeast Pacific, dated at least to the late Tortonian, c. 8.4 Ma. Magophoca n. gen. is the second Monachinae (with Noriphoca gaudini) found to possess six upper incisors instead of four as in the other members of the sub-family. Further characters, such as the deep fossa for the m.
Characterization of the Podospora anserina (Rabenh.) Niessl peroxidase gene family
Cryptogamie, Mycologie 45 (2)
Major role of peroxidases in plant biomass degradation is well-established in the white rot basidiomycetes. On the contrary, peroxidases are not used for this purpose by brown rot basidiomycetes, which use instead a non-enzymatic mechanism. In the case of the ascomycetes, not much is known although these fungi have peroxidase genes. Here, we identify and characterize the peroxidase genes of Podospora anserina (Rabenh.) Niessl, an ascomycete used to study development and lignocellulose degradation. We show that this fungus has one class II peroxidase, one hybrid B peroxidase, one haloperoxidase, four functional aromatic peroxygenases, one glutathione peroxidase, one cytochrome C peroxidase and one alkyl peroxidase, but lacks a dye peroxidase.
La reconnaissance des espèces basée sur l’ADN : applications, perspectives et défis en milieu continental terrestre
Naturae 2024 (3)
In response to ongoing global changes, the challenge of monitoring the dynamics of biodiversity is growing and leads to a strong demand for rapid and detailed assessments of changes in biodiversity. Molecular identification of species is increasingly used to replace or complement more traditional ecological monitoring methods. Metabarcoding is considered a tool for inventorying, learning about biology (predators, prey, pollinators, etc.) and even discovering the history of ecosystems. It can generate biodiversity data quickly, accurately and reliably on a wide range of organisms. This type of methodology is particularly interesting for monitoring systems lacking the expertise to distinguish the many species of hyper diverse groups such as insects or those that are difficult to survey.
Three new species of Satsuma Adams, 1868 (Gastropoda, Camaenidae) from Taiwan
Zoosystema 46 (3)Three new species of the genus Satsuma Adams, 1868, Satsuma hsuehshan n. sp., Satsuma nivnu n. sp., and Satsuma sunlinksea n. sp. from western Taiwan are described. Satsuma hsuehshan n. sp. is characterized by a dextral shell, curved basal lip, and the presence of a penial pouch. Satsuma nivnu n. sp. is characterized by a dextral shell, whorl not descending behind aperture, curved basal lip, and the presence of a penial pouch. Satsuma sunlinksea n. sp. is characterized by a dextral shell, straight and slightly downward basal lip, and the absence of a penial pouch. The penial pouch is a newly discovered structure in the reproductive system of Satsuma. The three new species were collected in a mountainous, middle altitude mixed forest.
Visual methods for documenting the preservation of large-sized synapsids at Richards Spur
Comptes Rendus Palevol 23 (7)
Large isolated skeletal elements, including those of sphenacodontid and ophiacodontid synapsids from the upland cave systems of the Richards Spur locality, Oklahoma, are described. Multiple forms of visual representation, including coquille and stipple drawings, are used to document and examine the isolated elements. A fragmentary anterior portion of a dentary has the sphenacodontid four-leaf clover plicidentine attachment within the tooth roots, but the teeth are all of uniform size, and the symphyseal area is relatively slender and does not curve upward, suggesting that the specimen may not belong to any known member of the clade.
Novitates neocaledonicae XV: Two new species of Endiandra R.Br. (Lauraceae) from New Caledonia
Adansonia 46 (3)
Two new species of Endiandra R.Br. are described from New Caledonia. Endiandra humboldtiana Munzinger & McPherson, sp. nov. is distinguishable from Endiandra lecardii Guillaumin and E. neocaledonica Kosterm. only by rather subtle details of flower size (3 mm long versus 2-2.5mm), leaf indument and distribution, even though molecular data indicate that it is genetically closer to an undescribed species from Roches de la Ouaième. Endiandra trichogyna Munzinger & McPherson, sp. nov. had previously been confused with E. baillonii (Pancher & Sébert) Guillaumin, but is easily distinguished from that and all other species present in New Caledonia by its densely pubescent ovary. A preliminary identification key is presented.
