Plant growth is greatly influenced by the rhizosphere microbiome, which has been traditionally investigated from a bottom-up perspective assessing how resources such as root exudates stimulate microbial growth and drive microbiome assembly. However, the importance of predation as top-down force on the soil microbiome remains largely underestimated....

The atmospheric ozone concentrations have substantially increased in the surface layer over the past decades, and consequently exhibited a strong influence on soil microbial communities and functions. However, the effect of elevated ozone (eO3) on the abundance, diversity, and structural complexity of soil nematode communities are elusive under dif...

Soil organisms drive major ecosystem functions by mineralising carbon and releasing nutrients during decomposition processes, which supports plant growth, aboveground biodiversity and, ultimately, human nutrition. Soil ecologists often operate with functional groups to infer the effects of individual taxa on ecosystem functions and services. Simult...
Plastics in all shapes and sizes have become widespread across ecosystems due to intense anthropogenic use. As such, they can interact with other contaminants that accumulate in the terrestrial environment, such as pharmaceuticals, metals or nanomaterials (NMs). These interactions can potentiate combined toxic effects in the exposed soil organisms,...

When plant leaves die, they fall and accumulate on the soil where an important process occurs: they decompose. Decomposition is essential for recycling nutrients and returning them to the soil. It is mainly done by an army of creatures called microbes, invisible to the naked eye, that slowly make the dead leaves rot. But larger creatures, like mill...

为了掌握中药材种植对土壤动物群落的影响,于2020年7月对成都市彭州境内种植期为3年和5年的黄连和重楼样地的小型土壤节肢动物进行了调查。共分离到小型土壤节肢动物526只,隶属于4纲17目69科98类或属,优势类群为等节跳属、平懒甲螨属、符跳属和副跳属。小型土壤节肢动物群落组成结构在不同中药材样地间差异明显,影响群落组成结构的主要是原等跳属、奥斯甲螨属和表刻螨科。黄连样地小型土壤节肢动物总类群数多于重楼样地,但两者间的小型土壤节肢动物群落平均密度及多样性指数差异均不显著。随种植年限增加,黄连样地小型土壤节肢动物群落密度显著下降,重楼样地的Shannon多样性则显著增加。冗余分析结果表明: 土壤碱解氮、pH、全钾、速效钾是影响小型土壤节肢动物群落组成结构的主要因子。研究发现,种植不同中药材对小型...

Phytosanitary treatments with pesticides are widely used to control pests and diseases in vineyards. An important part of the dispersed pesticide reaches the soil, affecting the fauna, producing quantitative and qualitative changes in the edaphic population’s structure and physiological activities. This study aims to evaluate the temporal dynamics ...
Abstract: The supply of recent photosynthate from plants to soils is thought to be a critical mechanism regulating the activity and diversity of soil biota. In the Arctic, large‐scale vegetation transitions are underway in response to warming, and there is an urgent need to understand how these changes affect soil biodiversity and function. We inve...
In spite of the high conservation value of soil fauna, the evaluation of their conservation status has usually been neglected. This is more evident for earthworms, one of the most important ecosystem service providers in temperate habitats but rarely the subject of conservation research. These studies have not been developed in Western Europe, whic...
