Summary: Arbuscular mycorrhizal fungi may influence competitive plant interactions, with Lolium multiflorum being the strongest competitor in the presence of AMF. Nitrogen fertilization did not affect the competitive balance, but phosphorus fertilization gave Lolium a competitive advantage over Trifolium. The differential C-P trade benefits driven by AMF may play a role in shaping the competitive outcomes between these two pasture species.

Summary: Agronomic inputs and technologies, especially fertilizers, play a role in the evolution of symbiotic partnership between arbuscular mycorrhizal fungi and cultivated plants. The use of MycoPatt method enhances resolution for the assessment of mycorrhizas in maize roots. Biostimulator treatment reduces root permissiveness for mycorrhizas. The presence of arbuscules and vesicles in different growth stages highlights the importance of mycorrhizas for plant nutritional needs. Mycorrhizal maps demonstrate the impact of biostimulators on colonization, causing a delay in growth stages for biostimulated plants. The forecast models reveal gradual colonization in plants without biostimulators, with the expansion of new hyphal networks. In contrast, biostimulated plants exhibit lower permissiveness for new colonization areas, relying on hyphae developed in previous growth stages.

Summary: The cultivation of different preceding green manure crops for one season did not have a strong impact on the AMF colonization or microbial diversity in onion roots or surrounding soil. The overall fungal and bacterial populations in the soil were more influenced by seasonal variations rather than preceding crops. Therefore, one season is too short to affect the AMF community in boreal climate organic fields with conventional tillage, and non-host preceding crops can also be included in rotations.

Summary: In a subarctic climate, seasonal shifts in temperature, precipitation, and plant cover drive temporal changes in microbial communities in topsoil. Ant nests harbor significantly different microbial communities compared to surrounding bulk soil, with some taxa consistently present over years and enriched compared to reference soils. Bacterial communities in ant nests show temporal stability, while fungal communities exhibit greater variation, potentially due to unique biochemical processes influenced by ant activities.

Summary: Methylmercury (MeHg) is a potent neurotoxin formed primarily by microbial methylation of inorganic mercury (Hg(II)). Recent research suggests that MeHg can also be produced in oxygen-rich pelagic waters, but the process and its drivers are still unclear. In this study, researchers conducted an experiment to test the hypothesis that inputs of terrestrial dissolved organic matter (tDOM) to coastal waters enhance MeHg formation through increased bacterial activity. The results showed that MeHg formation was linked to elevated bacterial production rates, which, in turn, were influenced by tDOM inputs. The study's findings have significant ecological implications in the context of global climate change, as they highlight the potential risk of increased MeHg exposure to pelagic biota.

Summary: Climate-smart agriculture, conceptualized by the Food and Agriculture Organization, aims to address the objectives of increasing food security, building resilience to climate change, and reducing greenhouse gas emissions. However, a lack of a comprehensive evaluation tool limits our understanding of how agricultural systems simultaneously tackle these challenges. To bridge this gap, we have developed a generic evaluation framework using 19 indicators in a sample of representative farms in Guadeloupe. The results highlight variations in performance across farming systems and can guide the design of innovative production systems.

Summary: This study examines the impact of installation factors and environmental factors on the concentrations and total loads of 15 elements in runoff from a vertical greenery system. The results show that substrate type is the most influential factor, with a reed-based substrate with high organic matter leading to higher concentrations and total loads. Substrate type also interacts with other factors, such as PGPM inoculation reducing the total loads of certain elements. Additionally, simulated rainwater quantity and substrate moisture interact with substrate type, affecting the concentrations and total loads of different elements.
