An invariability-area relationship sheds new light on the spatial scaling of ecological stability

open access: yesNature Communications, 2017
Just as species distribution patterns scale with area, so might the degree of variability in ecological properties. Here, Wanget al. develop a model invariability–area relationship and demonstrate the application of this theory to empirical data on plant

Drivers of Precision Agriculture Adoption in Italian Viticulture

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the main drivers influencing the adoption of two types of precision farming technologies in the viticultural sector: Decision Support Systems (DSSs) and Variable Rate Technologies (VRTs). We apply a partial proportional odds model and find that socio‐demographic characteristics are not significant determinants of adoption ...

A workflow for extracting ungulate trails in wetlands using 3D point clouds obtained from airborne laser scanning

open access: yesFrontiers in Remote Sensing
Ungulates and other mammalian herbivores can create trails in dense vegetation by trampling and browsing. This can affect vegetation structure and result in the fragmentation of closed, high vegetation, with subsequent impacts on biodiversity.
