On the conspecificity of Carinaulus coreensis (Kim) and C. inexpectatus (Balthasar) (Coleoptera, Scarabaeidae, Aphodiinae)
No full textThe genus Carinaulus Tesař, belonging to the scarab beetle subfamily Aphodiinae, currently includes 20 valid species distributed across the Eastern Palearctic and Oriental Regions. The genus is characterised by the following elytral features: broad and deep striae; striae prominently punctate and distinctly crenulate; intervals tectiform with a median carina; and the sixth and eighth intervals joined at the pre-apical area, though lacking a carina in that region. Two species are recognised in the Korean Peninsula, Carinaulus inexpectatus (Balthasar, 1935) in North Korea and Carinaulus coreensis (Kim, 1986) in South Korea. Carinaulus inexpectatus (Balthasar, 1935), with Vladivostok designated as its type locality, occurs in the Russian Far East and North Korea, whereas C. coreensis (Kim, 1986) is considered endemic to South Korea.During examination of Korean Carinaulus Tesař, we compared several specimens of Carinaulus coreensis (Kim, 1986), including a paratype and C. inexpectatus (Balthasar, 1935) collected from North Korea. We found that the two nominal species cannot be distinguised by the morphological characters, including labrum chaetotaxy and male genitalia. Accordingly, it is proposed that Aphodius coreensis Kim, 1986, is a subjective junior synonym of Aphodius nexpectatus Balthasar, 1935
Morphology and phylogeny of two new species of deep-sea mushroom soft corals (Octocorallia, Corallidae, Anthomastinae) from the Southern Mid-Atlantic Ridge
No full textMembers of the subfamily Anthomastinae Verrill, 1922, commonly known as mushroom soft corals, are characterized by their capitate or mushroom-shaped red colonies and large autozooids. Deep-sea mushroom corals of this subfamily remain poorly documented in the South Atlantic. This study describes two new Anthomastinae species, Neoanthomastus longistylus sp. nov. and Anthomastus mirabilis sp. nov., from the Southern Mid-Atlantic Ridge at depths of 1,553–2,145 m. Neoanthomastus longistylus sp. nov. is characterized by a slender stalk, siphonozooids distributed on the capitulum and the upper third of the stalk, and tentacular sclerites that are predominantly straight rods and rods with one end curved. Anthomastus mirabilis sp. nov. is distinguished by the presence of dumbbells in its tentacles, clubs and dumbbells in the anthocodial wall, and the absence of spindles. The mitochondrial genome of N. longistylus sp. nov. contains 14 PCGs, 2 rRNAs, and 1 tRNA, while that of A. mirabilis sp. nov. comprises 17 PCGs, 2 rRNAs, and 1 tRNA, with three duplicated genes – ND3, ND6, and ND4L – that are identical in sequence. Phylogenetic analyses based on the partial mtMutS gene and 13 PCGs from the mitochondrial genomes (mtMutS not included) reveal the phylogenetic relationships within the subfamily Anthomastinae. These are the first records of both genera from the Southern Mid-Atlantic Ridge, enriching the known species diversity and providing critical baseline data for future biodiversity assessments
Development of Pickering emulsion stabilized by Peperomia pellucida L. extract and beta-glucan: an in vitro study for wound healing applications
No full textExcessive reactive oxygen species (ROS) impair wound healing by inducing oxidative stress and compromising fibroblast function. To address this, we developed a novel Pickering emulsion (PESUBG) incorporating Peperomia pellucida extract, rich in flavonoids, and beta-glucan, a bioactive polysaccharide. The formulation exhibited small droplet size, low interfacial tension, and robust stability under thermal stress, freeze-thaw cycles, and prolonged storage. Amphiphilic flavonoids contributed to interfacial stabilization and antioxidant activity, with PESUBG demonstrating the highest radical-scavenging capacity among all tested formulations. In in vitro assays, PESUBG (50 μg/mL) significantly enhanced fibroblast viability compared to the base emulsion control (100.32 ± 11.47%) and improved cell survival under H₂O₂-induced oxidative stress (22.00 ± 2.66% increase), while also promoting collagen synthesis. These findings suggest that PESUBG is a promising bioactive and biocompatible formulation with the potential to mitigate oxidative stress and support tissue regeneration. Further studies are warranted to optimize formulation parameters and validate its wound-healing efficacy in vivo
A new species of Nitocra Boeck, 1865 (Copepoda, Harpacticoida) from Vietnam
No full textAn undescribed taxon of the species-rich genus Nitocra was found during a survey on the harpacticoid copepods from the hyporheic zone in Vu Gia–Thu Bon Rriver, Central Vietnam. The new species, N. duyxuyenensis sp. nov., is morphologically similar to the American N. evergladensis Bruno & Reid, 2002. These two species can be separated by the number of marginal spinules on the anal operculum, the relative length of the baseoendopod of the female fifth leg, the structure of the antenna, the number of setae on the female fifth leg, the number of setae on the inner margin of the first endopodal segment of the second to fourth swimming legs of the males, and the number of setae on the third endopodal segment of the third swimming leg. Additionally, some comments on the groups and subgroups of the genus defined so far are given, with the proposal of the lacustris species subgroup for group III of Gómez et al. (2012)
A new species of Myotis from China with notes on the siligorensis species group (Chiroptera, Vespertilionidae)
No full textOn the basis of molecular and morphological studies of samples collected in China, a new Myotis species belonging to the siligorensis group is described, Myotis kalkoae Tiunov, Jiang, & Liu, sp. nov. The species rank of M. sowerbyi and M. alticraniatus was confirmed. All three taxa under consideration belong to different genetic lines and can be distinguished from each other and from other morphologically similar species based on the shape of their baculum and tragus. The difficulties of taxonomy within the M. siligorensis species group are discussed
Late Oligocene petrified wood remains from alluvium sediments of Radomir Depression, Bulgaria
No full textThe paper presents a xylotomic study of some samples of petrified wood collected from alluviums in the Vladimir village (Radomir Depression, Bulgaria). Most likely they were transported from Late Oligocene coal-bearing sediments (Chattian) of Pernik or Bobov Dol areas. The samples have been identified as wood of Taxodioxylon taxodii, a fossil equivalent of the recent species of Taxodium distichum. The latter is a tree which grows presently in restricted areas of South USA, Mexico and Guatemala, but used to be widespread in the fossil records of the European Cenozoic flora as leaf imprints, wood remains and even as an important member in the Tertiary coal forests
A century of treeline and forest line data for Betula pubescens subsp. czerepanovii across high elevations in Norway
No full textThe global climate is warming, especially in northern regions due to high-latitude amplification. This high-latitude warming leads to range expansion with advancing tree- and forest-lines (TFLs) in the Northern Hemisphere. However, empirical studies can rarely provide a well-documented elevational expansion rate, especially for timescales longer than 40–50 years. This study provides a unique long-term dataset on TFL dynamics of Betula pubescens subsp. czerepanovii in Norway, based on a combination of resampled historical data (n = 319) and new field registrations (n = 447).Our dataset includes a total of 766 registrations from five counties in Norway. In total, the dataset contains 439 treelines and 327 forest lines, most likely representing the highest recorded TFLs for the region at the given time. For all data, both resampled and new, locality, coordinates, elevation, aspect and spatial uncertainty and the resampling/sampling methods and definitions are provided. The entire material is stored and available for download through the Global Biodiversity Information Facility (GBIF) portal.This dataset includes newly-resampled TFLs, based on 57–127-year-old registrations. The entries provide elevational changes, georeferenced localities and potential sites for monitoring climate change effects. The entries enable regional analyses of TFL dynamics on intermediate timescales, including the effect of time lags. The material is available for modelling TFL range shifts along the boreal-alpine ecotone. This dataset most likely provides the highest registered Betula pubescens subsp. czerepanovii locations within their specific regions, thus representing the contemporary ecophysiological range limits for the life-form tree. Additional high-elevation TFL sites and localities have been added to make the material suitable for future remapping and monitoring of climatic TFL dynamics
New species and newly recorded species of the family Strophariaceae (Agaricomycetes, Agaricales) in China
No full textTwo new species, Pholiota songjiangensis and Pyrrhulomyces pileocystidiatus, and one species newly recorded in China, Agrocybe eduardii, are described in this study. All of these species belong to the family Strophariaceae. Pholiota songjiangensis is characterized by a pallid pileus with appressed and concentric squamules, a white stipe covered with light yellowish-brown small scales, ellipsoid to ovoid basidiospores with an obvious germ pore, pleurocystidia as chrysocystidia, and cheilocystidia with two shapes: elongate-cylindrical with a capitulate apex and narrowly lageniform. Pyrrhulomyces pileocystidiatus is characterized by a bright orange-red to ochraceous brown pileus with an obtuse umbo, bitter taste, blackening basidiomata, pleurocystidia as chrysocystidia, and broadly clavate and orange-red pileocystidia. The specimens of Agrocybe eduardii collected from China in the present study closely matched the original morphological description of this species. These three species are described and illustrated, and phylogenetic analysis of a multigene dataset (ITS+nrLSU) is presented. Morphological and phylogenetic analyses confirmed that Pholiota songjiangensis and Pyrrhulomyces pileocystidiatus were distinctly different from other Pholiota and Pyrrhulomyces species, respectively. The Chinese samples formed a monophyletic group with the holotype of Agrocybe eduardii, confirming its newly recorded status from China when combined with the morphological evidence. Keys to species of Pyrrhulomyces, Agrocybe from China, and Pholiota subgenus Pholiota from China are provided
