Climate adaptation and functional constraints drive pollen evolution in Apiales
New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

On the Cauchy problem for non-local Ornstein--Uhlenbeck operators
, 2015 We study the Cauchy problem involving non-local Ornstein-Uhlenbeck operators in finite and infinite dimensions. We prove classical solvability without requiring that the L\'evy measure corresponding to the large jumps part has a first finite moment ...

Leaf Length Predicts Twig Xylem Vessel Diameter Across Angiosperms
Plant, Cell &Environment, Volume 49, Issue 3, Page 1330-1339, March 2026.ABSTRACT As plants grow taller, increasing conductive pathlength imposes hydraulic resistance, challenging the maintenance of water transport to leaves. While tip‐to‐base conduit widening along the stem helps mitigate this resistance, theoretical models and empirical data suggest that stem widening alone is insufficient to fully compensate.

Localisable moving average stable and multistable processes [PDF]
, 2009 We study a particular class of moving average processes which possess a property called localisability. This means that, at any given point, they admit a ``tangent process'', in a suitable sense.

Research on Three‐Dimensional Autonomous Obstacle Avoidance Path Planning Methods for UAVs
Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.This study presents a three‐dimensional autonomous obstacle‐avoidance path planning method for unmanned aerial vehicles (UAVs) based on a deep reinforcement learning (DRL)‐enhanced Mayfly Algorithm. The traditional Mayfly Algorithm suffers from issues such as random initial population generation and slow convergence.

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 418-434, February 2026.Abstract Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual movements separately from space use, home ranges and residency.

Fluctuating Growth Rates Link Turnover and Unevenness in Species‐Rich Communities
Ecology Letters, Volume 29, Issue 2, February 2026.Through a minimal model of ecological community dynamics, we explain how the interplay between environmental stochasticity, intra‐ and interspecific competition and dispersal relates to the maintenance of diversity, the commonness of rarity and compositional turnover.

Dynamical Behaviors of Stochastic SIS Epidemic Model with Ornstein–Uhlenbeck Process
AxiomsControlling infectious diseases has become an increasingly complex issue, and vaccination has become a common preventive measure to reduce infection rates. It has been thought that vaccination protects the population. However, there is no fully effective
