Herbivore species asynchrony underpins multitrophic stability across plants, herbivores and predators

Journal of Animal Ecology, EarlyView.
Across a grassland food web, multitrophic stability was most closely associated with herbivore species asynchrony. By identifying herbivores as a key source of temporal buffering between plants and predators, this study shows that intermediate consumers can play a central role in stabilizing the complex food web.

Drought and Nitrogen Addition Modulate Wolf Spider‐Associated Responses in a Detrital Food Web Without Detectable Functional Cascades

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Predators are important regulators of grassland biodiversity and ecosystem functioning, but their top‐down effects on detrital food webs under global change remain poorly understood. Using a field mesocosm experiment in a temperate grassland, we show that drought and nitrogen addition independently altered the effects of wolf spiders on soil fauna and ...

Ensembling Crop Models and Multi Criteria Analysis to Unlock Bioenergy From Marginal Lands: A Scenario‐Based Assessment From Italy

GCB Bioenergy, Volume 18, Issue 8, August 2026.
Multi‐Criteria Analysis to identify marginal land on which three crops (Safflower, castor bean, and Ethiopian mustard) were simulated with two process‐based models (DSSAT, ARMOSA) under two different agronomical management minimums (rainfed and no fertilization) and low input (half‐water and half‐nitrogen).

Soil nitrous oxide measurement methods: Collar adaptors and comparison of manual versus automatic chamber headspace sample collection

Journal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Manually operated non‐flow‐through non‐steady‐state chambers have been a dominant method for soil measurements of nitrous oxide (N2O) emission due to low cost, simplicity, and adaptability to different experimental designs. However, the use of automated dynamic non‐steady‐state chambers that deliver measurements in real‐time has increased in ...
