TipQuant: a robust algorithm for quantitative analysis of spatiotemporally dynamic activities in tip‐growing cells

open access: yesNew Phytologist, EarlyView.
Tip Quantification enables quantitative analyses over versatile selections of regions of interest. Summary Cell polarity and tip growth rely on the dynamic spatial organization of signaling and structural components. Quantitative characterization of these spatiotemporal dynamics is critical for understanding polarized cell growth, yet manual ...

Antipredatory Strategies of Anurans: An Updated Conceptual Review

open access: yesEthology, Volume 132, Issue 9, Page 662-708, September 2026.
To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.
