Summary: In this study, we investigated the monophyly of genera in the Gleicheniaceae family using extended sampling and genomic data. The results confirmed the monophyly of most genera, except for Sticherus. We also found that while most Gleicheniaceae genera originated during the Mesozoic, some genera showed diversification in the Neogene and Quaternary periods. Our findings suggest the importance of reticulation and polyploidy in this diversification process, and identify Rouxopteris and Stromatopteris as evolutionary relics.

Summary: In this study, phylogenetic analyses were conducted on Perenniporia species and related genera using DNA sequences of multiple loci. It was found that the genus Perenniporia is polyphyletic. Based on morphology and phylogeny, 15 new genera were proposed, 2 new species were described, and 37 new combinations were proposed. Illustrated descriptions of the new species were provided, along with identification keys to Perenniporia and its related genera.

Summary: The genus Poecilimon has 145 species, with the Poecilimon ornatus group having the greatest diversity in the Balkans. The study aimed to test the hypotheses of the P. affinis complex within the P. ornatus group using morphological data. Results suggest that male tegmen and male cercus are good morphostructures to distinguish taxa within the P. affinis complex.

Summary: This study investigated the phylogeny and biogeography of Buthacus species in the Levant, supporting a revised classification and revealing two geographically-separated clades. The divergence between these clades occurred in the Early Miocene in the Levant, coinciding with the existence of two land bridges allowing fauna exchange between Africa and Asia.

Summary: The Neogastropoda, including several model organisms, have unresolved phylogenetic relationships and unstable classification. In this study, a new molecular phylogeny of the neogastropods was constructed using mitogenomes from GenBank. The study revealed new relationships but also highlighted the need for additional data to revise the classification. Furthermore, the study showed the challenges of using complex models to handle the evolutionary history of mitogenomes.

Summary: This study investigates the phylogeny and biogeography of the pantropical whip spider family Charinidae using morphology and multilocus DNA sequences. Charinidae are monophyletic, with Weygoldtia as the sister group to a monophyletic group comprising Charinus and Sarax. The divergence of Charinus and Sarax coincides with the fragmentation of Pangaea.

Summary: Seventy-two morphological characters and three ecological characteristics were measured to assess variation and phylogenetic relationships among twelve species and three infraspecific taxa of the genus Spathoglottis from Peninsular Malaysia and Borneo. The morphological analyses divided Spathoglottis into two main groups based on the colours of the flower: Purple-Flowered Spathoglottis and Yellow-Flowered Spathoglottis. Species within the two groupings were further classified based on the size of the plants (Large/Dwarf Purple Spathoglottis and Large/Dwarf Yellow Spathoglottis) and the shapes of the labellum (spathulate, bilobulate or narrow/thread-like). The selected morphological characters appeared to support the taxonomic boundaries between two mostly debated taxa in the genus, S. aurea and S. microchilina.

Summary: Researchers have developed a tool called REFMAKER that can extract nuclear genomes from genome sequencing data for phylogenetic analysis in plant systematics. The tool constructs a catalog, selects nuclear regions, removes duplicate sequences, and generates consensus sequences from low-coverage sequencing data. The results demonstrate that REFMAKER is able to successfully reconstruct phylogenetic trees from low-coverage sequencing data.

Summary: Metchnikovella dogieli belongs to the early diverging microsporidian group and shows primitive characteristics compared to typical microsporidia. These hyperparasites infect gregarines parasitizing marine invertebrates. The species was discovered in the silt littoral zone at the coast of the White Sea in North-West Russia and described based on light microscopy.

Summary: Vannellida, a type of amoebae, have distinctive morphological features that set them apart from other lobose amoebae. A newly discovered species, Vannella primoblina, exhibits well-developed dorsal relief similar to Thecamoeba, but molecular analysis places it in the genus Vannella. This finding suggests that dorsal folds may be a characteristic of certain vannellid amoebae and not exclusive to Thecamoeba.

Summary: This study addresses an inverse scattering problem for synthetic aperture radar (SAR) data in through-the-wall imaging, utilizing a fully nonlinear model that shows better accuracy in estimating dielectric constants and target locations compared to the commonly used linearized models. The results demonstrate the effectiveness of the proposed method in accurately estimating dielectric constants and target locations hidden behind walls.

Summary: Research shows that young adults who consistently co-administer cannabis with tobacco are more likely to have frequent and persistent tobacco smoking in the long term. Therefore, young adults who use cannabis should be advised to avoid co-administering cannabis with tobacco, making them an important target group for tobacco cessation interventions.

Summary: Researchers have discovered a new species named Balamuthia spinosa n. sp. in the brackish-water sediments of Niva Bay in the Baltic Sea. Additionally, they found fragments of Legionella pneumophila genome in this species, suggesting it may be a vector of Legionella in the environment. Furthermore, phylogenetic analysis revealed a close relationship between the genera Stygamoeba and Vermistella, providing more evidence for the order Stygamoebida.

Sometimes co-administering cannabis and tobacco predicted more frequent cannabis use in the future, but did not predict high levels of use in the long term (4 1/2 years).

Summary: This study describes a new freshwater species, Thecamoeba vumurta n. sp., which has minor morphological differences but significant differences in the SSU rRNA gene sequence compared to the widely distributed species Thecamoeba striata. The findings emphasize the importance of gene sequencing for the reliable identification of Thecamoeba species and propose distinguishing species groups based on morphological characteristics when molecular studies are not available.

Summary: In this study, the effect of linker rigidity and conjugation degree on the morphology and optical properties of aggregates formed by silver nanoparticles (NPs) was systematically investigated. The concentration profiles obtained for effective NP linking were found to be non-monotonic. Transmission electron microscopy and absorption spectroscopy revealed that stilbene and tolane compounds effectively linked the silver NPs, forming quasi-spherical aggregates and elongated dimers/trimers, while bibenzyl compound exhibited surface-initiated azo conversion instead of NPs bridging. It was observed that the degree of NP aggregation decreased with increasing aromaticity and springiness of the linker molecule. The ability of rigid diamines to assemble nanoparticles with a finite degree of aggregation, even at high concentrations, distinguishes them advantageously from aliphatic bifunctional linkers. Highly stable plasmonic aggregates suitable for nano- and meta-materials and imaging applications can be obtained using this method.

Summary: Metchnikovellida are hyperparasitic microsporidia that live in gregarines found in the intestines of marine invertebrates. Recent studies have shown that the diversity of metchnikovellids may be higher than previously thought, even within a single host organism. Four species of metchnikovellids were found in the gut of the polychaete Pygospio elegans from littoral populations of the White and Barents Seas. Different metchnikovellid species can infect gregarines within a single worm, but simultaneous infection with multiple metchnikovellid species has never been observed.

Summary: Aphelids, a holomycotan group, are parasitoids that infect algae and form a sister lineage to Fungi. Despite their sister relationship to fungi, aphelids do not show signs of similarity in terms of their osmotrophic abilities, and their osmotrophic abilities appear to be reduced compared to free-living unicellular opisthokonts.
