Capturing spiral radial growth of conifers using the superellipse to model tree-ring geometric shape
(Frontiers Media, 2015)
Tree-rings are often assumed to approximate a circular shape when estimating forest productivity and carbon dynamics. However, tree rings are rarely, if ever, circular, thereby possibly resulting in under- or over-estimation ...
Effects of agricultural intensification on ability of natural enemies to control aphids
(Springer Nature, 2015-01-26)
Agricultural intensification through increasing fertilization input and cropland expansion has caused rapid loss of semi-natural habitats and the subsequent loss of natural enemies of agricultural pests. It is however extremely ...
A general method for parameter estimation in light-response models
(Springer Nature, 2016)
Selecting appropriate initial values is critical for parameter estimation in nonlinear photosynthetic light response models. Failed convergence often occurs due to wrongly selected initial values when using currently ...
