Modified F‐tests for assessing tree radial growth under linear‐circular regression models with correlated errors: A comprehensive toolbox rooted in G. E. P. Box's theorems

open access: yesCanadian Journal of Statistics, Volume 54, Issue 3, September 2026.
Abstract Annual tree growth is a complex biological process. Modelling radial growth in the trunk by linear‐circular regression with one mode and correlated errors has allowed the definition and assessment of a preferred direction for 1 and 2 years. Here, modified F$$ F $$‐tests are presented for 3 years, 1 mode/year; 1 year, 2 modes for possible main ...

Extrapolation strategy matters when transferring ecological niche models: new visualization tools for informed decisions

open access: yesEcography, Volume 2026, Issue 9, September 2026.
Abstract Ecological niche models (ENMs) are commonly used to predict species' potential distributions across space and time, allowing researchers and practitioners to assess invasion risk, estimate the impacts of future climate change, and reconstruct past distributions.

Toward Repurposing Global Passive Air Sampling Networks for Insect Monitoring: Promises and Pitfalls of Airborne eDNA

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
Our key findings show that polyurethane passive air samplers can sample insects, although highly abundant insects tend to be overrepresented. Our results also suggest that airborne eDNA might give us a broad temporal image of the insect communities over several weeks, rather than a snapshot of when samples are collected.

Using programmable infusion pump in avian species – a validation methodology in geese

open access: yesWildlife Biology, Volume 2026, Issue 5, September 2026.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Are Species Distribution Models That Use Climate Variables Suitable to Forecast the Changing Distribution of Freshwater Organisms?

open access: yesFreshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Species distribution models can be used to identify locations with environmental conditions suitable for populations in the past, present and future. However, climate variables commonly applied in species distribution models may be unsuitable for freshwater species because their explanatory power is difficult to assess.
