The area of Donji Kamenjak (Istria, Croatia) is locus typicus for the species Octodrilus istrianus Mršić, 1991. However, the whole earthworm fauna has not been investigated. Given that O. istrianus is an endemic species to the Istrian region, this fact inspired our research in this small, but unique location. Field samplings were conducted over a t...

Soil organic matter (SOM) transformation processes are regulated by the activities of plants, microbes, and fauna. Compared with plants and microbes, effects of soil fauna are less understood because of their high taxonomic and functional diversity, and mix of direct and indirect effect mechanisms. Trait‐based approaches offer a generic perspective...

The trait-based approach is increasingly used for soil invertebrates. Complementary to the taxonomy based approach, the trait-based approach can provide a more mechanistic understanding of the responses of organisms to environmental disturbances and of their effects on soil functioning. However, the application of the trait-based approach across st...

As soil invertebrates with a unique digestive system, earthworms are regularly used as bioindicators and test organisms. Due to their burrowing activity and casting, earthworms are involved in the structuring of the soil. However, this way of life exposes them to different pollutants, including microplastic particles. Although the use of plastics i...

Various endogenous and exogenous factors influence the occurrence of oxidative stress in all organisms, as well as in dogs. An increase in reactive oxygen species (ROS) concentration and the occurrence of oxidative stress can lead to changes in the structure of proteins, lipids, and DNA. The level of oxidative stress can be determined by measuring...

Every year, worldwide olive oil extraction processes produce huge amounts of by-products such as (olive mill wastewater and olive mill pomace) in a short period of time. These products are a major problem that affects the soil. Therefore, the aim of this study was to investigate the single and simultaneous effects of different olive mill wastes and...

Excessive application of fungicides in crop fields can cause adverse effects on soil organisms and consequently affect soil properties. Existing knowledge on the effects of strobilurin fungicides has been primarily based on toxicity tests with active ingredients, while the effects of fungicide formulations remain unclear. Therefore, this work aims...

Soil invertebrates (i.e., soil fauna) are important drivers of many key processes in soils including soil aggregate formation, water retention, and soil organic matter transformation. Many soil fauna groups directly or indirectly participate in litter consumption. However, the quantity of litter consumed by major faunal groups across biomes remains...

Due to the often-excessive usage of fungicides, increasing attention is being paid to their impact on soil and non-target organisms. Risk assessments are usually based on the pure active ingredient and not on the formulated products applied in the environment. The aim of this study was therefore to investigate how azoxystrobin, the best-selling str...

Continuous accumulation and low degradation rates of plastic waste in the environment indicate the cumulative effect that microplastics particles could have on the environment. The impact of microplastics pollution on terrestrial ecosystems, relative to aquatic ecosystems, has been poorly investigated. Also, the impact of soil microplastics on soil...

Industrial residues and wastes with higher content of naturally occurring radionuclides represent a potential ecological risk to the biota residing in the vicinity of the disposal sites.
