Niche construction on environmental gradients : the formation of fitness valley and stratified genotypic distributions
The process of niche construction can alter the trajectory of natural selection through organism-environment feedback. As such, the mechanism and impact of niche construction can be better investigated along environmental ...
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 ...
The impact of land abandonment on species richness and abundance in the Mediterranean Basin : a meta-analysis
Land abandonment is common in the Mediterranean Basin, a global biodiversity hotspot, but little is known about its impacts on biodiversity. To upscale existing case-study insights to the Pan-Mediterranean level, we conducted ...
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 ...
The development of a spatio-temporal model for water hyacinth biological control strategies
(University of Georgia, 2016)
A reaction-diffusion model for a temporally variable and spatially heterogeneous environment is developed to mathematically describe the spatial dynamics of water hyacinth and the interacting populations of the various ...
