Soil invertebrates of coniferous forests along a gradient of air pollution (Komi Republic)

Background

The role of soil invertebrates in the cycle of substances, soil-forming processes and the provision of ecosystem services is undeniable. Therefore, soil invertebrates are valuable in bioindication studies. Comprehensive research of soil invertebrates in the production area of Mondi Syktyvkar JSC as the largest pulp and paper enterprise in the European part of Russia was initiated in 2003. A huge amount of data about composition, abundance and structure of soil macro- and mesofauna along an impact gradient was accumulated during the period from 2003 to 2019 years. These data can be used to study local biodiversity, monitor the state of soil invertebrate communities and assess the impact of the pulp and paper industry on the environment.

New information

Datasets here presented include information from a monitoring programme for soil invertebrates that inhabit coniferous forests in the production area of Mondi Syktyvkar JSC (Komi Republic). The assemblages' structure of macrofauna, collembolans and nematodes are described. Information on the number of individuals of springtail species, nematodes genera and macrofauna taxa is given. A total of 11146 sampling events of macrofauna, 6673 sampling events of Collembola, and 2592 sampling events of Nematoda are recorded along a gradient of air pollution from pulp and paper industry emissions.

Occurrences of Threatened Species included in the Third Edition of the Red Data Book of the Komi Republic (Russia)

BACKGROUND

The purpose of the data paper was to introduce into scientific literature the results of scientific work carried out for the third edition of the 'Red Data Book of the Komi Republic'. The article reflects methodological approaches to the formation of a list of rare and in need of protection species and describes the corresponding datasets published in GBIF.

NEW INFORMATION

Information about 7,187 occurrences of 438 rare species and infraspecies included in the third edition of the 'Red Data Book of the Komi Republic' have been published.

Soil invertebrates occurrences in European North-East of Russia

BACKGROUND

The European North-East of Russia is the territory which includes the Nenets Autonomous District, represented by the East European tundra (from Kanin Peninsula to Vaigach Island), Komi Republic with its taiga ecosystems and the Urals (Northern, SubPolar and Polar). Over 20 years of systematic studies of soil fauna in the studied region has resulted in a huge amount of data being accumulated that can be analysed from different positions. Considering that the representation of Russian soil biota data, especially from European North-East of Russia in the GBIF database is not large, our data are of great interest to the scientific world community. The accumulation of such data will solve questions on national and global scales using large arrays.This study produced a dataset containing information on occurrences on soil invertebrates (Lumbricidae, Chilopoda, Diplopda, Collembola, Elateridae and Staphylinidae) in the European North-East of Russia. The dataset summarises occurrences noted in natural and disturbed forests, tundra and mountain ecosystems.

NEW INFORMATION

Data from 196 geo-referenced localities of European North-East of Russia (tundra, taiga and mountains ecosystems) have been collated. A total of 5412 occurrences are included in the resource. The current project surveys 13 species of earthworms, 20 species of millipedes, 246 species of springtails, 446 species of rove beetles and 60 species of click beetles. The diversity of soil invertebrates in the European North-East of Russia has not been fully explored and further exploration will lead to more taxa.

CORRELATIONS BETWEEN PERSONAL CHARACTERISTICS AND PHYSICAL FITNESS IN HEALTHY STUDENTS AND STUDENTS WITH CHRONIC DISEASES

Aim. The article deals with establishing correlations between personal characteristics and physical fitness in healthy students and students with chronic diseases. Materials and Methods. 426 first-year male and female students from the Irkutsk State University took part in the study. In all first-year students, we studied personal psychological characteristics: personal adaptation potential, motivation to success, anthropometric data (body weight, body height, BMI). We also studied the parameters of physical fitness. Results. In healthy female students, we revealed a direct correlation between physical fitness (pull ups) and personal adaptation potential. In females with chronic diseases, we established a direct correlation between abdominal muscles strength and personal adaptation potential. In healthy males, we found out the dependence between BMI and motivation to success. Conclusion. In first-year students (male and female), we revealed the positive correlations between personal characteristics and physical fitness.
