New records of Lumbricidae and Collembola in anthropogenic soils of East European tundra

Abstract

The terrestrial environment of the East European tundra consists of a mosaic of habitat types. In addition to the natural habitat diversity, various human-influenced types may occur. In the town of Vorkuta, Komi Republic, Russia the manure-enriched soils near hydrogen sulfide springs were observed. This site represents an unusually nutrient-rich location with considerable development of organic soils, in contrast to the naturally forming soils in East European tundra which are typically thin and nutrient poor. In these organic soils, two species of Lumbricidae and two species of Collembola previously not recorded from the natural ecosystems in the study area of research territory were found. One earthworm species, Dendrodrilus rubidus tenuis, is likely to have been introduced. The presence of the three other species (Eiseniella tetraedra, Folsomia fimetaria, and Proisotoma minuta) is quite natural in East European tundra and such anthropogenic soils with high organic content may be a good habitat for them.

Springtails (Hexapoda: Collembola) of some plant communities of the Pechora delta

“…Folsomia fimetaria is found in shrub lichen tundra of Khabuika. It is very difficult to explain its record, as previously this species was found only in anthropogenic soils in Vorkuta and Kola Peninsula [Babenko, 2012;Kolesnikova et al, 2019]. Sminthurinus trinotatus is characteristic species in dry and hot places and its records in Bolvansky Nos can be explained by the thawing effect of the Pechora River [Lavrinenko et al, 2016].…”

“…The infrequent reports (also in the Antarctic) probably connect with sporadic introductions by humans." Thus, the checklist of springtails of East European tundra including anthropogenic soils increased to 198 species [Babenko et al, 2017;Kolesnikova et al, 2019;present study].…”

Advancing Soil Health: Challenges and Opportunities in Integrating Digital Imaging, Spectroscopy, and Machine Learning for Bioindicator Analysis

“…The integration of ML and CV is regarded as a revolutionary advancement for the evaluation of soil fauna. To integrate ML modes with CV for processing soil fauna images, a diverse set of soil fauna images with accurate labels is first collected from various sources, including soil sample extractions , and cultivation in controlled environments . The images are then preprocessed to remove noise using different filters, adjusting brightness and contrast, and resizing them to a standard size using relevant software including Fiji ImageJ, GIMP, and IrfanView. , Some soil fauna, especially earthworm images, can also be found from ImageNet .…”

Keanekaragaman Organisme Pada Rhizosfer Gulma Siam Di Lahan Vulkanik, Pesisir, Dan Karst

“…Kepadatan mikroarthropoda menurun seiring dengan peningkatan kedalaman dan elevasi tanah, terutama karena ketersediaan bahan organik (Illig et al, 2010). Ekosistem tanah yang terbentuk dengan pengaruh antropogenik namun memiliki kandungan bahan organik yang tinggi dapat menjadi habitat yang baik bagi organisme tanah khususnya cacing dan collembola (Kolesnikova et al, 2019). (Kesaulya et al, 2015).…”
