    Spatial networks reveal how forest cover decreases the spread of agricultural pests by Débora C. Rother, Leandro G. Cosmo, Julia Tavella, Fredric M. Windsor, Mariano Devoto, Darren M. Evans, Paulo R. Guimarães Jr.

    Published 2025-04-01
    “…Therefore, using only information about the direct and indirect pathways of the spatial network and the initial focus of infestation, we were able to predict with nearly 80% accuracy the most susceptible sites to pest spread in the simulated landscape. By adjusting parameters such as pest mobility, and interaction with landscape features, our model can simulate different agricultural systems and pest behaviors, showing that forest cover can be used to control pest occurrence and that direct and indirect pathways in spatial networks can be used as a predictive tool to manage the pest spread in agricultural landscapes.…”

    Turbulent Transport Efficiency of Momentum and Sscalar over Forest Canopy in Southern Sichuan by Yi DING, Yu ZHANG, Demin FAN, Youqi SU, Qian ZHANG, Yanqi WANG, Yanqi WANG

    Published 2025-06-01
    “…The turbulent transport characteristics of momentum and scalar over the canopy were studied by using the three levels (20 m, 38 m and 56 m) turbulence data measured at the 60m forest micro meteorological tower in southern Sichuan from May 1 to June 30, 2021.Coherent structure is the main form of turbulent motion, which is composed of updraft (ejection) and downdraft (sweep).In this paper, the quadrant analysis method is used to analyze the boundary of the roughness sublayer, roughness sublayer and constant flux layer above the forest canopy and the ejection-sweep motion characteristics of the constant flux layer, including the difference of ejection and sweep contribution to flux, the difference between momentum and scalar transport, and the difference between different scalar (T, q, CO2) transport.The results show that under unstable and stable conditions, the ejection dominates the scalar transport at all three levels, while the sweep is the main eddy current motion for scalar transport above the roughness sublayer under neutral conditions.For the momentum flux, under unstable conditions, the ejection dominates at all three levels.Under stable conditions, the ejection dominates at the roughness sublayer and the constant flux layer, while at the boundary of the roughness sublayer and the constant flux layer, the effect of the sweep is greater than that of the ejection.Under neutral conditions, the flux contribution of the sweep is greater than that of the ejection except for the roughness sublayer.The third-order cumulant expansion method (CEM) can more accurately express the flux contribution caused by ejection and sweep, while the incomplete cumulant expansion method (ICEM) is poor in simulating the temperature at the boundary of roughness sublayer and constant flux layer.Through the calculation of transmission efficiency, the difference between momentum and scalar transmission is further quantified.The turbulent transfer efficiency of momentum decreases with increasing instability, while the heat transfer efficiency is the opposite.Atmospheric stability is an important factor controlling momentum and scalar transfer, and the transfer efficiency of water vapor is less affected by atmospheric stability.Under the condition of strong instability, the heat transfer efficiency is more effective than other scalar transfer.…”
