Ecography, EarlyView.Reproductive phenology influences ecosystem functioning and climate sensitivity in tropical montane cloud forests, but phase‑specific climatic thresholds and the temporal coupling between flowering and fruiting remain poorly quantified over decadal scales. We analyzed a 36‑year monthly record (1983–2018) from a Venezuelan cloud forest (15 focal species)

High‐Order Projection‐Based Upwind Method for Simulation of Transitional Turbulent Flows
International Journal for Numerical Methods in Fluids, EarlyView.In this study, we evaluated the implicit large‐eddy simulation capabilities of the mass‐conserving mixed stress method for transitional turbulent flows and proposed an efficient solution method for large‐scale applications. The results presented in this work show promising outcomes for incompressible aerodynamic flow problems, which can be further ...
