Global fine-resolution data on springtail abundance and community structure.

Springtails (Collembola) inhabit soils from the Arctic to the Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database on springtail communities that includes 249,912 occurrences from 44,999 samples and 2,990 sites. These data are mainly raw sample-level records at the species level collected predominantly from private archives of the authors that were quality-controlled and taxonomically-standardised.

Decompression Surgery Options for Metastatic Cervical Spine Lesions.

: Metastatic spinal lesions occur in 70% of patients with incurable cancer, and the most common site for bone metastases is the spine. Over the last decade, medical science has made significant progress in treating tumor damage to the spine. The study examined the efficacy of decompression surgery for patients with metastatic cervical spine lesions contributing to spinal cord compression.

Sympatry of genetic lineages of s. l. (Collembola, Isotomidae) in the East European Plain.

(Schaeffer, 1896) is one of the most abundant eurytopic species of springtails in temperate regions of the northern hemisphere, and is often used as a model species for studies on the genetics of soil microarthropod populations. Six genetic lineages (L0, L1, L2, L3, L4-Saltzwedel, L4-Hebert) are known which are distributed mainly parapatrically in Western and Central Europe. Individuals of from 21 locations on the East European Plain were analyzed.

Globally invariant metabolism but density-diversity mismatch in springtails.

Soil life supports the functioning and biodiversity of terrestrial ecosystems. Springtails (Collembola) are among the most abundant soil arthropods regulating soil fertility and flow of energy through above- and belowground food webs. However, the global distribution of springtail diversity and density, and how these relate to energy fluxes remains unknown.

Mitogenome selection in the evolution of key ecological strategies in the ancient hexapod class Collembola.

A longstanding question in evolutionary biology is how natural selection and environmental pressures shape the mitochondrial genomic architectures of organisms. Mitochondria play a pivotal role in cellular respiration and aerobic metabolism, making their genomes functionally highly constrained. Evaluating selective pressures on mitochondrial genes can provide functional and ecological insights into the evolution of organisms.

High-quality genomes reveal significant genetic divergence and cryptic speciation in the model organism Folsomia candida (collembola).

The collembolan Folsomia candida Willem, 1902, is widely distributed throughout the world and has been frequently used as a test organism in soil ecology and ecotoxicology studies. However, it is questioned as an ideal "standard" because of differences in reproductive modes and cryptic genetic diversity between strains from various geographical origins. In this study, we obtained two high-quality chromosome-level genomes of F.

Biotransformation of Androstenedione by Filamentous Fungi Isolated from Cultural Heritage Sites in the State Tretyakov Gallery.

The transformation of steroids by microorganisms is widely used in medical biotechnology. A huge group of filamentous fungi is one of the most promising taxa for screening new biocatalytic reactions in order to obtain pharmaceutically significant steroids. In this work, we screened 10 filamentous fungi-destructors of egg tempera for the ability to biotransform androst-4-en-3,17-dione (AD) during cultivation in a liquid nutrient medium or in a buffer solution.

A Multifield Study on Dimethyl Acetylenedicarboxylate: A Reagent Able to Build a New Cycle on Diaminoimidazoles.

A new effective method for the synthesis of imidazo[1,5-]pyridazines derivatives (yields = 68-89%) by the interaction of 1,2-diamino-4-phenylimidazole with DMAD, in methanol and in the presence of a catalytic amount of acetic acid, is proposed. The course of reaction has been examined by classical organic methods, HPLC-MS analysis, and quantum-chemical calculations.

A new blind genus of Anurophorinae (Collembola: Isotomidae) with seven anal spines from Northwest China.

Drivers of Collembola assemblages along an altitudinal gradient in northeast China.

Altitudinal changes in the diversity of plants and animals have been well documented; however, soil animals received little attention in this context and it is unclear whether their diversity follows general altitudinal distribution patterns. Changbai Mountain is one of few well-conserved mountain regions comprising natural ecosystems on the Eurasian continent. Here, we present a comprehensive analysis of the diversity and community composition of Collembola along ten altitudinal sites representing five vegetation types from forest to alpine tundra.

Taxonomy of the complex. VI. Rediscovery of the genus Salmon, 1951 and epitoky in (Barra, 2001), comb. nov. from South Africa.

The genus Salmon is restored and given a diagnosis. It takes an intermediate position between Börner and Willem complexes and is characterized by the separation of the two last abdominal segments (like in ) and 3 and 5 s-chaetae on the fourth and fifth abdominal segments (like in and its allies). A list of and key to species belonging to is given.

The extremely high diversity of Collembola in relict forests of Primorskii Krai of Russia.

Background: The diversity of soil animals of relict forest ecosystems in East Asia continues to be insufficiently studied and almost not represented in international databases, including GBIF. This article is based on 7550 records of 175 species which were collected in Ussuriiskii, Sikhote-Alinskii and Kedrovaya Pad' natural reserves of Russian Far East in 2016-2017. A multi-scale sampling design allowed us to estimate population densities and local species richness of Collembola at areas of different sizes.
