Both density‐ and frequency‐dependent effects determine plant growth in a dune heath ecosystem

open access: yesOikos, Volume 2026, Issue 8, August 2026.
We tested the hypothesis that both density‐ and frequency‐dependent interactions play important roles in determining plant growth in a dune heath ecosystem at several levels of available nitrogen. Plant growth was measured using the pin‐point method in a five‐block experiment with four nitrogen levels.

Ecological examples of nonstationarity, nonlinearity and statistical interactions in dynamic structural equation models

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 8, Page 2510-2523, August 2026.
Abstract Ecologists are adapting structural causal modelling for spatial, phylogenetic and time‐series analysis. However, ecological extensions of path analysis and structural equation models (SEM) typically assume that interactions among variables are stationary, linear and additive, while ecological and evolutionary dynamics are often nonstationary ...

Comparing Methods for Measuring Predation: Toward a Quantitative–Informative Indicator of Natural Pest Control

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 801-811, August 2026.
Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

The Impact of TikTok on Elections: (Mis)information and Regulatory Challenges

open access: yesKyklos, Volume 79, Issue 3, Page 724-742, August 2026.
ABSTRACT TikTok's algorithm‐driven feed is reshaping electoral communication, yet a clear understanding of its effects is lacking. This study synthesizes and appraises evidence on how the platform's design and governance shape political (dis)information and may affect electoral dynamics.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1683-1707, July/August 2026.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.
