Karst caves, formed by the erosion of soluble carbonate rocks, provide unique ecosystems characterized by stable temperatures and high humidity. These conditions support diverse microbial communities, including wall microbial fouling, aquatic biofilms, and planktonic communities. This study discloses the taxonomic diversity of protists in aquatic biotopes of Shulgan-Tash Cave, a culturally significant site and popular tourist destination, by 18S rRNA gene metabarcoding. Our findings reveal the rich protist communities in the cave’s aquatic biotopes, with the highest diversity observed in Blue

Abstract The goal of this study was to assess the role of Cystoseira phytocenosis as a biochemical barrier to the phosphorus detrophication through the phytoplankton primary production in waters of the specially protected natural area (SPNA) “Cape Martyan” on the southern coast of Crimea. We present data on the mineral phosphorus concentration in seawater and in the brown algae Cystoseira (Cystoseira s.l.) phytocenosis in 2021 and the phytoplankton primary production in 2017 – 2019. In the SPNA sublittoral zone, wet weight of the Cystoseira phytocenosis was estimated at 1425.6 tons, the produc

Introduction. About 90% of TB patients have side effects of anti-TB therapy in the form of gastrointestinal disorders. Currently, the role of disorders of the intestinal microbiocenosis in the formation of dyspepsia has been proven. In turn, dyspeptic syndrome leads to a decrease in patient adherence to treatment, which affects the effectiveness of tuberculosis treatment. The most dangerous in this regard are second-line anti-tuberculosis drugs used in the treatment of drug-resistant tuberculosis.

Soils contain more K than any other nutrient; nevertheless, most of the K is inaccessible for plant absorption. In crop production, chemical fertilizers have been associated with several unfavorable outcomes that have a significant detrimental influence on environmental sustainability. Potassium-solubilizing bacteria (KSB) solubilize K-bearing minerals and transform insoluble K into soluble forms, which can be absorbed by plants. Therefore, solubilizing insoluble K in a plant-available pool using K-solubilizing bacteria could be an alternative and viable way to sustain crop production and main

To identify vectors and characterize the virus, mosquitoes were collected in both years in zoological gardens and on a horse meadow immediately following the diagnosis of disease cases in birds and horses. Mosquitoes were identified and screened for WNV by qRT-PCR, with virus-positive samples being sequenced for the viral envelope protein gene. While no positive mosquitoes were found in 2018, seven mosquito pools tested positive for WNV in 2019

Plants rely on potassium for many critical biological processes, but most soils are potassium limited. Moving potassium from the inaccessible, mineral-bound pool to a more bioavailable form is crucial for sustainably increasing local potassium concentrations for plant growth and health. Here, we use a synthetic soil habitat (mineral doped micromodels) to study and directly visualize how the saprotrophic fungus, Fusarium sp. DS 682, weathers K-rich soil minerals. After 30 days of fungal growth, both montmorillonite and illite (secondary clays) had formed as surface coatings on primary K-feldspa

The problem of weed resistance to herbicides has become very important in the last decade and threatens to dramatically reduce the productivity and profitability of modern crop production. Herbicides – ALS inhibitors dominate among current herbicides and are used annually on large areas of sunflower, wheat, corn, soybean, and rapeseed. Also, in recent years, Clearfield seeds of sunflower, corn, canola, soybean and wheat have been sown in large areas. In recent years, there has been a sharp decrease in Amaranthus retroflexus L. control levels by imidazolinone class herbicides. Thus, the effects

A diversity of all-female fishes of the genus Poeciliopsis coexists with their sexual ancestor species in streams of western Mexico. All-females are hybrids that depend on the sperm of paternal species to reproduce. Rare-female advantage is one of several hypotheses that attempt to explain how the diversity of all-female biotypes is maintained within the Poeciliopsis reproductive complexes. According to this hypothesis, the uncommon all-female biotype has a mating advantage over the common ones and has been maintained by a dynamic equilibrium process.
