Four new species of the genus Scheloribates (Oribatida, Scheloribatidae)-S. (Scheloribates) flexibilis Ermilov sp. nov., S. (S.) monosetosus Ermilov sp. nov., S. (S.) triangulus Ermilov sp. nov., S. (Topobates) tredecim Ermilov sp. nov.-are described, based on adults collected from litter in the afroalpine and bamboo locations in Ethiopia. Scheloribates (S.) flexibilis differs from the related species S. (S.) longisetosus by the length of aggenital, anal and adanal setae and the morphology of setal bothridial head and anterodorsal part of the leg tibia II. Scheloribates (S.) monosetosus differs from the related species S. (S.) concentricus by the length of anal and adanal setae and translamellar line, and the morphology of the setal bothridial head. Scheloribates (S.) triangulus differs from the related species S. (S.) monosetosus by the morphology of ventrodistal part of the leg femora II-IV, number of setae on the leg genu II, the length of the prolamella, and the development of the notogastral seta p1. Scheloribates (T.) tredecim differs from the related species S. (T.) scheloribatoides by the absence of the prolamella, distinctly longer aggenital, anal and adanal setae, and narrower body.

Root nodule symbiosis is traditionally recognized in the Fabales, Fagales, Cucurbitales, and Rosales orders within the Rosid I clade of angiosperms. However, ambiguous root nodule formation has been reported in Zygophyllaceae and Roystonea regia (Arecaceae), although a detailed analysis has yet to be conducted. We aimed to perform morphological analyses of root structures in these plants and utilize metagenomic techniques to identify and characterize the bacterial populations within the nodule-like structures.

The gut microbiome plays an important role in insect evolution and ecology. Bacteria support the host's nutrition and defense and therefore play an important role in the fitness of the host. Halyomorpha halys is one of the most important invasive pest species in the world.

Polyploidization (diploidy → polyploidy) was more likely to be positively associated with seed mass than with seed germination. Polyploidy is common in flowering plants, and polyploidization can be associated with the various stages of a plant's life cycle. Our primary aim was to determine the association (positive, none or negative) of polyploidy with seed mass/germination via a literature review.

Objective: To evaluate the toxic effects of the agent Relatox on mature outbred rats and mice in an acute experiment in comparison with the registered analogue Dysport.
Material And Methods: Based on the aim of experiment, the acute toxic effects of Relatox and Dysport were assessed on two animal species: rats and mice at intraperitoneal and intramuscular administration at dose levels that made it possible to calculate the toxicological parameter values (initially 10-150 U/kg with subsequent usage of additional doses 20 U/kg to 300 U/kg depending on the agent and route of administration). The LD values and other acute toxic parameters were calculated using probit analysis.

This study presents the preparation and electrochemical testing of sulfonated styrene-grafted poly(vinylidene fluoride) (pVDF) copolymers as proton exchange membranes (PEMs) for semi-organic redox flow batteries (RFBs) based on 9,10-anthraquinone-2,7-disulfonic acid (AQDS)/bromine. The copolymers are synthesized via a two-step procedure, involving i) atom transfer radical polymerization of styrene (Sty) for the grafting to the pVDF backbone and ii) the sulfonation of the polystyrene grafted side chains. Copolymers with different amounts of sulfonated styrene (SSty) in the side chains (i.
