Adding invasive alien plant-derived biochar and stinging nettle powder in Populus nigra phytoremediation of arsenic- and lead-contaminated Technosol alters microbial community assembly and network stability

Snezhana Mourouzidou, Magkdi Mola, Alex Ceriani, Spiros Papakostas et autres

This study examined the effects of biochar and nettle Urtica dioica amendments on microbial diversity and community assembly in a historically contaminated Technosol collected from a former silver‑lead mine in Pontgibaud (Puy-de-Dôme, France). We investigated how two types of biochar obtained from …

The Bug‐Network ( BugNet ): A Global Experimental Network Testing the Effects of Invertebrate Herbivores and Fungal Pathogens on Plant Communities and Ecosystem Function in Open Ecosystems

Anne Kempel, George C. Adamidis, José D. Anadón, Joe Atkinson et autres

Plants are consumed by a variety of organisms, including herbivores and pathogens, which significantly impact plant biomass, diversity, community composition, and ecosystem functioning. While the impacts of vertebrate herbivores are well established, the effects of consumer groups such as insect herbivores, mollusks, …

Legacy effects of invasive plant species on soil bacterial community assembly, β-diversity, and ecological interactions

Pantelitsa D. Kapagianni, Magdi Mola, Spiros Papakostas, George P. Stamou et autres

Abstract No invasive-specific effects on bacterial community composition and biomass. The identity of invaders’ legacy impacted the robustness of bacterial networks. Legacy of C. bonarienzis exerts strong filtering effect on soil bacterial β-diversity. S. elaeagnifolium legacy promotes the stochastic regulation of bacterial …

Seasonal dynamics and functional diversity of soil nematode communities under treated wastewater irrigation in abandoned agricultural soils

Magkdi Mola, Eleni Stratilaki, Snezhana Mourouzidou, Panagiotis Kougias et autres

The use of treated wastewater (TWW) for agricultural irrigation is becoming more popular as a sustainable alternative to freshwater due to increasing water scarcity. While considerable research exists on the effects of TWW on soil microorganisms, its impact on soil nematodes, key …

Altitude’s Impact on the Rhizosphere Prokaryotic Communities of the Cretan Endemic Plant Petromarula pinnata (L.) A.DC.

Rafaela Stagiopoulou, Ιfigeneia Mellidou, Nikos Krigas, Efimia M. Papatheodorou

The present study examined the effect of the three different altitudes on the enzymatic activity and the prokaryotic communities of the rhizosphere of Petromarula pinnata (L.) A.DC. (Campanulaceae), a vulnerable local endemic species of Crete (Greece). It was observed that the pH …

The Differentiations in the Soil Nematode Community in an Agricultural Field after Soil Amendment Using Composted Coffee Waste in Various Concentrations

Panagiotis Kekelis, Maria D. Argyropoulou, Aphrodite Theofilidou, Efimia M. Papatheodorou et autres

In a field experiment, composted coffee waste (CW) was used as soil amendment at three different rates (2%, 4%, and 8%) in plots cultivated with wheat; the effects on the soil nematode community and plant growth were studied. By sampling twice, i.e., …

Interventions Change Soil Functions and the Mechanisms Controlling the Structure of Soil Microbial Communities

Efimia M. Papatheodorou

Soil microbial communities play essential roles in maintaining ecosystem functions, such as litter decomposition, mineralization, nitrification, and denitrification, thus exerting control on primary production, soil fertility, and gas emissions [...].

The Invasion of Alien Populations of Solanum elaeagnifolium in Two Mediterranean Habitats Modifies the Soil Communities in Different Ways

Maria Karmezi, Nikos Krigas, Efimia M. Papatheodorou, Maria D. Argyropoulou

We aimed to explore how the invasion of the alien plant Solanum elaeagnifolium affects soil microbial and nematode communities in Mediterranean pines (Pinus brutia) and maquis (Quercus coccifera). In each habitat, we studied soil communities from the undisturbed core of both formations …

Use of Microbially Treated Olive Mill Wastewaters as Soil Organic Amendments; Their Short-Term Effects on the Soil Nematode Community

Maria Dimou, Nikolaos Monokrousos, Petros Katapodis, Panagiota Diamantopoulou et autres

Managing olive mill wastewater (OMW) is a major environmental problem. We followed two methods for OMW bioremediation: one with the white-rot fungus Pleurotus ostreatus alone and one with the fungus plus the microalga Chlorella vulgaris. To evaluate the potential use of both …

Fire and Rhizosphere Effects on Bacterial Co-Occurrence Patterns

Efimia M. Papatheodorou, Spiros Papakostas, George P. Stamou

Fires are common in Mediterranean soils and constitute an important driver of their evolution. Although fire effects on vegetation dynamics are widely studied, their influence on the assembly rules of soil prokaryotes in a small-scale environment has attracted limited attention. In the …
