title: Supplementary Material for: Investigating Alzheimer's Disease Progression Using a Radiomics Approach: The Hippocampal-Amygdala Border in FDG-PET Scans

description: Introduction: This study introduces a novel and simple radiomics approach to identify highly sensitive and interpretable imaging biomarkers for tracking Alzheimer's disease (AD) progression using FDG-PET imaging. Our unique focus is on a custom-defined hippocampal-amygdala border region. We hypothesize that this specific small, anatomically and biologically critical, yet underexplored interface region can effectively capture subtle, early-stage metabolic deterioration indicative of AD progression.
Method: We leveraged 18F-FDG-PET scans from 513 participants across the AD spectrum (Control Normal (CN), Mild Cognitive Impairment (MCI), Alzheimer's Disease (AD)) from the ADNI database. Building on the established involvement of the hippocampus, amygdala, and entorhinal cortex, we innovatively defined the hippocampal-amygdala connecting region using a distance transform approach to specifically capture the metabolic interplay between these vital structures. A rigorous radiomics pipeline was then applied, involving systematic evaluation of eight feature selection techniques combined with six classification models to identify the most effective predictive framework.
Results: Our findings demonstrate the high discriminatory power of the hippocampal-amygdala border region for AD diagnosis and monitoring of disease progression. A concise set of radiomic features derived from this single, novel ROI exhibited high predictive accuracy across various diagnostic distinctions: two features (specifically, shape MeshVolume Right and gldm SmallDependenceLowGrayLevelEmphasis left) distinguished AD from CN with ROC AUC=0.914; two distinct features predicted MCI from AD with ROC AUC=0.796; and two other features (shape LeastAxisLength left and glszm LargeAreaEmphasis left) differentiated CN from MCI with ROC AUC=0.691. Crucially, the mean values of these identified features consistently demonstrated statistically significant incremental deterioration (p&lt;0.05) across consecutive AD stages (CN to MCI, MCI to AD), underscoring their sensitivity to disease progression.
Conclusions: This study establishes the clinical potential of radiomics in providing highly sensitive and interpretable biomarkers for monitoring AD progression, specifically by targeting the novel, biologically-informed hippocampal-amygdala border ROI on FDG-PET. By identifying distinct, parsimonious sets of robust radiomic features for different disease stages, our approach offers an efficient, non-invasive, and clinically translatable tool that balances diagnostic power with interpretability, paving the way for its integration into existing clinical workflows for Alzheimer's disease.

title: Defining Species And Species Boundaries In Uroderma (Chiroptera: Phyllostomidae) With A Description Of A New Species

description: This dataset contains the digitized treatments in Plazi based on the original journal article Mantilla-Meluk, Hugo (2014): Defining Species And Species Boundaries In Uroderma (Chiroptera: Phyllostomidae) With A Description Of A New Species. Occasional Papers of the Museum 325, No. 325: 1-30, DOI: 10.5281/zenodo.15777607DEFINING SPECIES AND SPECIES BOUNDARIES IN URODERMA (CHIROPTERA: PHYLLOSTOMIDAE) WITH A DESCRIPTION OF A NEW SPECIESHUGO MANTILLA-MELUKABSTRACTA new species of Peter’s tent-making bat, genus Uroderma (Chiroptera: Phyllostomidae), is described from Venezuela’s Cordillera del Caribe and piedmonts of the Eastern Cordillera of the Colombian Andes. Cranial morphology of the new species approaches that of U. magnirostrum, with a notable enlargement of the nasals in the post-orbital region, giving the skull a flatter appearance in lateral profile than typical specimens of U. bilobatum. The new species of Uroderma can be distinguished easily from U. magnirostrum by several discrete skin and cranial characters. Taxonomic affinities among geographic variants of U. bilobatum were assessed through analyses of morphologic, karyotypic, and molecular variation. Although statistical support for well-defined groups was low in morphological assessments, four morphotypes were recognized based on geographic structure and previously reported karyotypic and molecular data. In addition to the newly recognized species, U. convexum Lyon 1902 is elevated to species status, and U. c. molaris is treated as a subspecies of U. convexum. Further, based on reciprocal monophyly of supported clades present in analyses of mitochondrial DNA data, assortment of karyotypes distinguished by three rearrangements, and reduced fitness in hybrids, U. davisi Baker and McDaniel 1972 is treated as a species. These taxonomic revisions result in a genus comprised of five species (U. bilobatum, U. convexum, U. davisi, U. magnirostrum, and U. bakeri sp. nov.).

title: Hildenbrandia ardreae sp. nov. (Rhodophyta), recorded before as Hildenbrandia dawsonii (nom. inval.)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Pedroche, Francisco F. (2024): Hildenbrandia ardreae sp. nov. (Rhodophyta), recorded before as Hildenbrandia dawsonii (nom. inval.). Phytotaxa 666 (4): 291-297, DOI: 10.11646/phytotaxa.666.4.4, URL: https://doi.org/10.11646/phytotaxa.666.4.4AbstractFour species of the red algal genus Hildenbrandia have been recorded from Pacific Mexico: H. dawsonii reported on the west coast of Baja California and Jalisco; H. occidentalis with one record from the west coast of Baja California; H. prototypus occurring all along the coast, including the Gulf of California; and the most common and abundant species, H. rubra from Pacific Baja California to Oaxaca, in tropical Pacific Mexico. All four species have been studied morphologically and molecularly using representative specimens. The molecular status regarding the phylogenetic position of H. dawsonii in relation to other species is unclear. H. dawsonii nomenclatural status was analyzed, and additional material from the University Herbaria at UC-Berkekley (UC) was reviewed. Hildenbrandia dawsonii is an invalid name because its alleged basionym (Hildenbrandia canariensis var. dawsonii) is invalid. Therefore, a new species is described: Hildenbrandia ardreae sp. nov., selecting a Dawson specimen from Punta Norte, Cedros Island, Baja California, as the holotype. Furthermore, morphological characters, once used as diagnostic at the species level, are considered irrelevant. The new holotype proposed in this study shows the same characteristics stated by F. Ardré in her original publication (1959) and could be a potential source for DNA extraction for comparative studies.

(Bacillariophyta) from the Yongle River in Hunan Province, China. PhytoKeys 250: 181-191, DOI: 10.3897/phytokeys.250.140576AbstractA new species, Ctenophora hunanensis Bing Liu & Rioual, sp. nov., found in the Yongle River, a tributary of the Xiang River (Hunan Province, southern China) is described on the basis of morphological observations made under light and scanning electron microscopes. Ctenophora hunanensis is distinguished from other Ctenophora taxa by a unique combination of characters that includes its lanceolate valve outline with rostrate apices, sternum gradually becoming wider from valve apices to center, and a greater valve width than the other members of the genus. Ctenophora hunanensis inhabits the epilithic community in the headwaters of a freshwater river. Many abnormal valves of C. hunanensis were observed in the samples investigated and the most frequent morphological abnormalities consisted in a lack of symmetry relative to the apical axis caused by a unilateral incising in the middle part of the valve.

Zootaxa 5155 (3): 439-448, DOI: 10.11646/zootaxa.5155.3.8AbstractTree Crickets, Oecanthus Serville, 1831 have a worldwide distribution, and are known as Tree Crickets because they are common in the treetops, even though many species occur in different strata of forest, and also in open fields. In this work we describe a new species of Oecanthus from Southern Brazil, based on the most significant diagnostic structures in the ocanthine taxonomy, such as the phallic sclerites and metanotal gland morphology, as well as calling song. The new species herein described has a distinct faint red spot between the eyes, a metanotal gland with a triangular posterior median lobe with the apex curved up and forward, the median lophi of pseudepiphallus slightly elongate with an U-shaped invagination, and the ectophallic distal arc prolongation with the posterior apex U-bifurcated. The calling song stands out among the local stridulating crickets for alternate a regular and an irregular train of chirps. Illustrations of the external morphology, information about type specimens, material examined, measurements, and spectrogram of the calling and courtship songs is provided.

description: This dataset contains the digitized treatments in Plazi based on the original journal article Wu, Xu, Ma, Dai-Kun, An, Ming-Tai, Feng, Yu-Cai, Yu, Jiang-Hong, Han, Ji-Huai (2025): Neillia daloushanensis, a new species of Neillia (Rosaceae) from southwest China. PhytoKeys 261: 175-187, DOI: 10.3897/phytokeys.261.152449AbstractThrough detailed morphological comparison and robust molecular evidence, we confirm Neillia daloushanensis M. T. An & Xu Wu as a new species of Rosaceae from Guizhou province, southwest China. Morphologically, N. daloushanensis closely resembles N. gracilis but differs in several key traits: it is a creeping liana rather than a low subshrub; its stems are 0.6–1.5 cm long compared to the slender stems less than 0.5 cm tall in N. gracilis; its leaves are larger, measuring 5–9 × 3–6 cm vs. 2.5–3.5 × 2–3 cm; stipules are sessile, clasping, and larger (0.8–1.3 × 0.6–1.1 cm) rather than peitiolate and smaller (0.4–0.6 × 0.3–0.5 cm) without clasping; calyx tubes are densely pilose on both surfaces and bear stipitate glands abaxially, in contrast to the slightly pubescent, glandless calyx tubes of N. gracilis; and the seed number ranges from 2 to 4 instead of consistently 2. These morphological distinctions are further corroborated by molecular phylogenetic analysis based on 703 single-copy nuclear genes, supporting the recognition of N. daloushanensis as a distinct species within the genus.
