The early scientists who studied the earthworm fauna of Bulgaria were Rosa (1897), Černosvitov (1934), and Mihailova (1966). Their work was continued by Šapkarev (1986) and Zicsi and Csuzdi (1986). In the last decade, researchers from Hungary, Serbia and Bulgaria organized explorations of many localities and enhanced the knowledge of the earthworm fauna of the country (Valchovski 2012, Stojanović et al. 2012, Szederjesi 2013). The present paper summarizes the new species records after these aforementioned three publications: Cernosvitovia munteniana, Eisenia andrei, Murchieona minuscula, Proctodrilus opisthoductus and Dendrobaena veneta.

Ecological integrity, encompassing physical, chemical, and biological aspects, is crucial for sustaining ecosystem service functions and stability. As the largest freshwater lake in China, the ecological integrity of Poyang Lake has attracted much attention due to the over-exploitation of its water resources in recent years. In this study, several biological and water quality surveys on water ecological conditions were carried out at 11 sampling points of Poyang Lake from 1998 to 2022, and the ecological health of Poyang Lake was evaluated by use of the O/E (Observation/Expectation) model and the chemical-biological index method according to the status of the water quality and the structure of the benthic fauna in the four seasons, respectively.

Molybdenum (Mo) acts as a crucial nutrient for plant development, yet excessive soil exposure can cause detrimental effects. Molybdenosis symptoms remain subtle in many plants, largely due to the safeguarding functions of soil organisms, the fundamental biological mechanisms lack clarity. In this study, we explored the potential mechanisms for amending Mo-exposed soils with soil microbe-arbuscular mycorrhizal fungi (AMF) and soil fauna, specifically earthworms, to enhance model plant-alfalfa growth resistance through soil nutrient turnover perspectives.

- - The article provides an overview of earthworm species in Georgia, revealing approximately 90 species from 13 genera found across the country, with a significant concentration in nature reserves.
- - It highlights that 46 of these species are endemic to the Caucasus, indicating the region's unique biodiversity and climatic conditions that contribute to this endemism.
- - Dendrobaena stands out as the most diverse genus among the Caucasian Lumbricidae, comprising 22 species, while several other genera have only one species each, showing variability in species richness.
Environmental fate of microplastics and common polymer additives in non-biodegradable plastic mulch applied agricultural soils.

Numerous studies have been conducted to investigate the impact of microplastics on soil eco-system, yet little attention has been given to the specific effects of mulch microplastics and the leaching of plastic additives from mulch films. This review inspects the propensity of commonly used plastic additives in mulch films, such as Di(2-ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and benzophenones (BPs), to migrate into soils and pose potential risks to soil biota. Further, we highlight the degradation of non-biodegradable plastic mulch films over time, which leads to an increase in the release of plastic additives and microplastics into agricultural soils.

Article Synopsis
- The study examines the accumulation of heavy metals (Pb, Zn, Cu) in soil, plant litter, and earthworms near busy roadways in urban parks of metro-Washington, DC, highlighting potential health risks for the environment and humans.
- Sampling across varying distances (1-30 m) from the road showed that lead concentrations were significantly higher closer to the road, while zinc accumulation in earthworms exceeded soil concentrations, indicating bioaccumulation.
- Despite the phase-out of leaded fuel in the 1980s, legacy lead contamination remains evident in roadside environments and is influenced by factors such as plant uptake, wind, and soil characteristics.
