Beyond species means – the intraspecific contribution to global wood density variation
New Phytologist, EarlyView.Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Homogeneous Observer‐Based Affine Formation Tracking
International Journal of Robust and Nonlinear Control, Volume 36, Issue 5, Page 2692-2704, 25 March 2026.ABSTRACT This article addresses the control of mobile agents, termed followers, to track a time‐varying affine formation specified by a set of leaders. We present a distributed hierarchical method composed of a homogeneous high‐order sliding mode observer and a tracking controller. The observer estimates the followers' target trajectories from neighbor

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.An iron‐catalyzed protocol for the cascade cyclization of N‐aryl and N‐benzoyl acrylamides promoted by methane and other gaseous alkanes is reported. The current protocol provides an efficient platform for the conversion of feedstock gaseous alkanes into complex and medicinally relevant N‐heterocycles.
