title: Discovery of the mountain glass snail, Hessemilimax kotulae (Westerlund, 1883) (Mollusca, Gastropoda, Vitrinidae), in the High Vosges Mountains (northeast France) and its conservation

description: This dataset contains the digitized treatments in Plazi based on the original journal article Bichain, Jean-Michel, Ryelandt, Julien (2023): Discovery of the mountain glass snail, Hessemilimax kotulae (Westerlund, 1883) (Mollusca, Gastropoda, Vitrinidae), in the High Vosges Mountains (northeast France) and its conservation. Zoosystema 45 (11): 409-419, DOI: 10.5252/zoosystema2023v45a11ABSTRACTWe report here four new localities for the mountain glass snail Hessemilimax kotulae (Westerlund, 1883) in the northeast part of France. These new records extend the range of this species considerably within the Vosges Mountains, where it was previously known from only a single site. Specimens were found at the base of or in scree slopes facing mainly north or northeast or along streams in fir or mixed forests, at elevations between 863 and 1145 m. Because H. kotulae is difficult to find and identify, we provide the description of habitats where the species has been found and the associated gastropod assemblages as well as morphological and anatomical characters in order to facilitate its identification by non-malacological conservationists. Finally, we revised the species conservation status on the French Red List. We further discuss the conservation of land snails that reach the upper limit of their distribution at the highest elevations of the low mountain ranges in north-eastern France, in the context of global warming.

title: Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain

description: This dataset contains the digitized treatments in Plazi based on the original journal article Pyron, R. Alexander, Beamer, David A. (2022): Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain. Zootaxa 5188 (6): 587-595, DOI: 10.11646/zootaxa.5188.6.6AbstractMost swamp-dwelling dusky salamanders of the genus Desmognathus from the Coastal Plain were long treated as a single species (Desmognathus auriculatus) ranging from east Texas to southeastern Virginia. This taxon concept was based on the name Salamandra auriculata Holbrook, 1838 with type locality Riceboro, Liberty County, Georgia and a type series that could not be located by later authors. Recent workers have been unable to locate or verify swamp-dwelling populations from east Texas and western Louisiana, which appear to be extirpated and may not have represented a distinct taxon from co-occurring lineages of D. conanti. Recent molecular phylogenies have supported at least four distinct species-level taxa within D. auriculatus. Populations from the Gulf Coastal Plain in eastern Louisiana, Mississippi, and southwestern Alabama were recently described as D. valentinei Means, Lamb, and Bernardo, 2017 and D. pascagoula Pyron, O’Connell, Lamb, and Beamer, 2022. This leaves two remaining species-level lineages with uncertain taxonomy and nomenclature: D. auriculatus A (Alabama, Florida, and Georgia), and D. auriculatus B/C (Georgia, South Carolina, and North Carolina), both of which occur near the type locality. We recently located a specimen at the Muséum national d’Histoire naturelle in Paris (MNHN 0.4675) that we concluded is one of Holbrook’s syntypes and designated it as the lectotype, but without allocation. Here, we use linear morphometrics to confidently allocate it to D. auriculatus A, bolstered by examination of three historical topotypic collections. This requires a new name for D. auriculatus B/C, which we describe as D. valtos sp. nov. (suggested common name: Carolina Swamp Dusky Salamander) from Otter Creek, Craven County, North Carolina. Other related and sympatric species of Desmognathus remain to be described from the Atlantic Coastal Plain and adjacent Piedmont of the southeastern United States.

title: Distribution, natural history, and conservation of Cambarus dubius in Pennsylvania

description: This dataset contains the digitized treatments in Plazi based on the original journal article Allison, Patrick F., Lieb, David A., Loughman, Zachary J. (2022): Distribution, natural history, and conservation of Cambarus dubius in Pennsylvania. Journal of Natural History 56 (13 - 16): 829-848, DOI: 10.1080/00222933.2022.2069056, URL: http://dx.doi.org/10.1080/00222933.2022.2069056ABSTRACTDue to their burrowing lifestyles that make them difficult to sample, the distributions and habitat associations of most burrowing crayfishes are poorly understood. A distributional study was conducted in south-western Pennsylvania to better understand the range and habitat associations of the primary burrowing crayfish Cambarus dubius within the state. A total of 790 new sites and six previously surveyed sites were sampled between the Chestnut Ridge and Allegheny Mountains, with the majority of these localities being roadside ditches. Crayfish were collected using a combination of burrow excavation, baited lines, and by hand. We utilised permutation-based t-tests to determine differences in habitat variables between sites with and without C. dubius and sites with and without any burrowing crayfish species. Cambarus dubius was collected from 61 total sites, and active crayfish burrows were observed at 137 additional sites. Cambarus carinirostris was collected from 13 sites, Lacunicambarus thomai was collected from six sites, and an exuvia of Procambarus acutus was collected from a stream at one site. New behavioural observations for C. dubius juveniles were observed while collecting specimens with baited lines. Sites with C. dubius had significantly more canopy cover and deciduous forest land cover and significantly less pasture-hay land cover than sites without C. dubius. Sites with burrowing crayfishes (all species) had significantly more canopy cover and deciduous forest land cover and significantly lower elevation, depth to the water table, percent sand substrate and pasture-hay land cover than sites without burrowing crayfish. In Pennsylvania, Cambarus dubius has not expanded its range in comparison to its historical range, and populations appear to be concentrated primarily in the southern valleys of the Chestnut Ridge and Allegheny Mountains.

title: Why the Fine-Structure Constant Appears Everywhere: Coherence as the Universal Grammar of Physics

description: Abstract

The fine-structure constant \(\alpha \approx 1/137.035999206\) is not a coupling strength—it is the universal phase-coherence margin of the primordial torsion field \(\mathcal{M}_\mu\) in Generalized Mass as Twisted Time (G-MaTT). We demonstrate that α appears across atomic, nuclear, astrophysical, and cosmological scales—not by coincidence—but because all physical phenomena emerge from the same geometric condition: when relative phase slips exceed \(\sqrt{\alpha}\), braid overlap decays exponentially, triggering decoupling, decoherence, or desynchronization. This single threshold governs:  atomic fine structure (\(\Delta E/E \sim \alpha^2\)),  neutron interferometry phase shifts (\(\Delta\phi \sim 2\pi\sqrt{\alpha}\)),  dark-matter velocity limits (\(v_{\text{crit}} = c\sqrt{\alpha/w}\)),  dark-energy frequency cutoffs (\(\omega_{\text{crit}} = \Omega_0\sqrt{\alpha}/(2\pi w)\)),  particle decay lifetimes (via TUT),  and cyclic cosmology (re-locking when \(\langle\Delta\phi\rangle < \sqrt{\alpha}\)).  

Thus, α is the angular resolution of reality—the maximal tolerable misalignment before coherence breaks. Its ubiquity is geometric necessity, not empirical accident.

title: <b>Alpha Cell Dysfunction in Type 2 Diabetes: The Role of Insulin Resistance and Reduced Insulin Secretion</b>

description: This study investigated how insulin resistance and impaired insulin secretion affect hyperglucagonemia during an oral glucose tolerance test (OGTT) in type 2 diabetes (T2DM).We conducted a retrospective analysis of 247 individuals with T2DM who underwent a 75g OGTT, measuring glucose, insulin, C-peptide, and glucagon. Insulin resistance was assessed via insulin sensitivity index (ISI) and homeostasis model assessment of insulin resistance (HomaIR), while residual β-cell function was evaluated using area under the C-peptide curve (AUCcp) and homeostasis model assessment of β-cell function (Homa-β). Generalized linear models and mediation analysis were used to examine associations between glucagon secretion, insulin resistance, and insulin secretion.Participants with the lowest insulin sensitivity (ISI Q1) and highest insulin resistance (HomaIRQ3) displayed significantly higher glucagon levels during OGTT. However, no significant elevation in glucagon levels was observed in those with the lowest residual insulin secretion (AUCcpQ1 or Homa-βQ1). Mediation analysis confirmed that neither AUCcpnor Homa-βmediated the link between insulin resistance (ISI/HomaIR) and glucagon levels, even after adjusting for confounders.In T2DM, impaired glucagon suppression during OGTT is linked to insulin resistance but not to reduced insulin secretion, underscoring insulin resistance's key role in alpha-cell dysfunction.

title: The unexpected gecko: A new cryptic species within Urocotyledon inexpectata (Stejneger, 1893) from the northern granitic Seychelles

description: This dataset contains the digitized treatments in Plazi based on the original journal article Lobón-Rovira, Javier, Rocha, Sara, Gower, David J., Perera, Ana, Harris, D. James (2022): The unexpected gecko: A new cryptic species within Urocotyledon inexpectata (Stejneger, 1893) from the northern granitic Seychelles. Zootaxa 5150 (4): 556-578, DOI: 10.11646/zootaxa.5150.4.5AbstractUrocotyledon inexpectata, a small gecko endemic to the granitic islands of the Seychelles, has previously been demonstrated to comprise two highly distinct clades based on mitochondrial and nuclear DNA sequences, with one lineage exclusive to a northern group of islands, and the second lineage exclusive to the more southerly islands. Here we complement the genetic data with additional analyses to determine if the clades should be considered distinct species. We present and analyse new morphological data, including skull and jaw osteology, and supplement the available genetic data with DNA sequences for individuals from the previously unsampled island of Felicité, which cluster with the other northern island samples. Despite the high morphological similarity between Urocotyledon populations from northern and southern islands, diagnostic characters were identified, with the northern lineage having a more completely ossified skull, more tooth loci on maxilla and dentary, shorter hindlimbs, relatively smaller eye diameter and relatively wider head. We therefore describe the northern lineage as a distinct species, Urocotyledon norzilensis sp. nov., and discuss the biological and conservation management implications of this taxonomic action.

ZooKeys 1209: 43-68, DOI: 10.3897/zookeys.1209.120812AbstractSpecimens of a caligid copepod (Siphonostomatoida) were found on the gills of the hairfin lookdown Selene brevoortii (Gill) (Carangidae) from off Mazatlán, Sinaloa (north-western Mexico). This material represents a new species of Caligus, C. selenecola sp. nov., and is assigned to the diaphanus species group. Within this group, only C. kapuhili Lewis, 1967, C. laticaudus Shiino, 1960, C. macrurus Heller, 1865, and C. selenecola sp. nov., have been described with a reduced outer spine 1 on the second exopodal segment of leg 1. These four species can be readily separated by the relative length of the abdomen, and the presence / absence of a process on the myxal area of the female maxilliped, the sternal furca, the postantennal process, and the spiniform process on the basal antennary segment. A full description of the new species is given with some comments on Caritus tolii Rangnekar, 1984.
