Online Jump and Kink Detection in Segmented Linear Regression: Statistical Optimality Meets Computational Efficiency

open access: yesJournal of Time Series Analysis, Volume 47, Issue 3, Page 727-748, May 2026.
ABSTRACT We consider the problem of sequential (online) estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that certain CUSUM‐type statistics attain the minimax optimal rates for localizing the change point.

Weighing the options: a test of alternative stomatal optimisation models at high temperatures

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1551-1568, May 2026.
Summary Stomatal optimisation models centre upon a fundamental tradeoff for plants: opening stomata promotes carbon uptake, but closing stomata prevents water loss. However, stomatal opening can occur at high temperatures, causing evaporative cooling which limits thermal damage to leaves.

Rearing duration influences survival rate in the Post‐Larval Capture, Culture and Release of a coral reef fish

open access: yesRestoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Juvenile coral reef fish face an initial predation‐induced mortality bottleneck with mortality exceeding 60% within 48 hours of settlement. This intense predation, exacerbated by anthropogenic stressors, limits recruitment and contributes to global declines of reef fish populations. Post‐Larval Capture, Culture, and Release (PCCR),
