Digitised herbarium specimen data reveal a climate change‐related trend to an earlier, shorter Canadian Arctic flowering season, and phylogenetic signal in Arctic flowering times

open access: yesNew Phytologist, Volume 251, Issue 2, Page 696-706, July 2026.
Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.

CAREx: context-aware read extension of paired-end sequencing data

open access: yesBMC Bioinformatics
Background Commonly used next generation sequencing machines typically produce large amounts of short reads of a few hundred base-pairs in length. However, many downstream applications would generally benefit from longer reads.

Assessing forage mass using smartphone imagery for cereal rye under grazing conditions in Nebraska

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Managing grazing efficiency requires reliable and practical tools to estimate forage mass. Traditional methods like clipping, though accurate, are time consuming and labor intensive. In this study, two imaging tools, Canopeo and the Crop Canopy Image Analyzer (CCIA), were evaluated for their efficacy in estimating the forage mass of cereal rye

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, Volume 54, Issue 2, June 2026.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Facilitative Effects of Alnus viridis ssp. fruticosa on Betula nana ssp. exilis Growth in Arctic Alaska

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We investigated how Siberian alder influences the growth of dwarf birch in the low Alaskan Arctic. Using growth rings, we found that Siberian alder promotes dwarf birch growth overall despite delaying and shortening the growing season through enhancing snow depths.

Direct Interaction Between Roe Deer and Mountain Hare, a Case of Interference Encounter Competition?

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Here, we report on a case of direct interaction between a roe deer doe and a mountain hare recorded by a camera trap in Tydal Municipality, Norway, suggestive of direct interference competition. The roe deer doe is following and displacing the mountain hare for at least 2 min and 29 s, including a 19 s active phase.
