Considering the ecological relevance of amphibians and the widespread agricultural use of herbicide mixtures, investigations addressing their joint toxicological effects are increasingly necessary. Here, we investigated the effects of a mixture of two commercially formulated herbicides widely used in combination in agriculture—2,4-D-based herbicide (DBH) and a glyphosate-based herbicide (GBH)—on tadpoles of Physalaemus cuvieri...
Soil microbial communities underpin ecosystem functions critical for sustainable agriculture, yet our understanding of how long‐term management of tropical agroecosystems shapes these communities remains limited. This is particularly the case in sub‐Saharan Africa where soil health challenges are most acute for food security. Using four long‐term (~20 years) experiments across contrasting agroecological zones in Kenya, we stud...
Digging for meaningful connections: associations between root phenotypes and rhizosphere microbial diversity in maizeNARA Subscribed
Background and Aims Drought threatens food security globally. Adaptive root phenotypes and microbiomes can improve maize ( Zea mays L.) water uptake and tolerance to drought. However, synergisms between root phenotypes and microbiomes remain underexplored. We aimed to investigate the association between varying root phenotypes and rhizosphere microbiomes under field-scale drought. Methods We grew 22 maize inbred lines in the f...
Temperate Forest Floors: Ecosystem Hubs in Transition?NARA Subscribed
The forest floor (FF) plays a key role in carbon, nutrient, and water cycling. It is the biologically most active compartment of forest soils, highly responsive to environmental conditions. Yet, its response to current changes in environmental conditions and forest management is understudied. Temperate forests are among the best studied ecosystems globally, providing the necessary ecological and biogeochemical background infor...
Aims Increasing droughts affect crop yield and health. Plants can respond to drought by adapting their root biomass, root morphology, and quality and quantity of rhizodeposition to improve water and nutrient uptake. Besides droughts, agricultural management influences roots and rhizodeposition; however, it is not well studied how agricultural management can affect the response of roots and rhizodeposition to drought. Methods A...

Soil water limitation intensity alters nitrogen cycling at the plant-soil interface in Scots pine mesocosmsNARA Subscribed
Background and aim More intense episodes of drought are expected to affect terrestrial nitrogen (N) cycling by altering N transformation rates, the functioning of soil microorganisms, and plant N uptake. However, there is limited empirical evidence of how progressive water loss affects N cycling at the plant-soil interface. Methods We adopted 15 N tracing techniques and metagenomic analyzes of microbial genes involved in N cyc...
Ongoing shifts in climate and land use have altered interactions between trees and insect herbivores, changing biotic disturbance regimes. However, as these changes are complex and vary across host species, insect taxa, and feeding guilds, they remain poorly understood. We compiled annual records of forest insect disturbance from 15 countries in temperate and boreal Europe, spanning the period from 2000 to 2022. The dataset co...
Impacts of Climate, Organic Management, and Degradation Status on Soil Biodiversity in Agroecosystems WorldwideNARA Subscribed
Unsustainable soil management, climate change, and land degradation jeopardize soil biodiversity and soil‐mediated ecosystem functions. Although the transition from conventional to organic agriculture has been proposed as a potential solution to alleviate these pressures, there is limited evidence of its effectiveness in enhancing belowground biodiversity across different biogeographical regions, climates, and land degradation...
Drought events are becoming more severe and recurrent over Europe. Changes in temperature and rain patterns can affect soil nutrient mobility and availability, modulating the biomass and activity of soil microbial communities. Here, we investigated the effects of drought on extracellular polymeric substances (EPS) and microbial biomass carbon (MBC) and nitrogen (MBN) in differently managed cropping systems. An on-field drought...
