The seesaw effect of winter temperature change on the recruitment of cotton bollworms Helicoverpa armigera through mismatched phenology
(John Wiley & Sons Ltd., 2015)
Knowing how climate change affects the population dynamics of insect pests is critical for the future of integrated pest management. Rising winter temperatures from global warming can drive increases in outbreaks of some ...
Increasing functional modularity with residence time in the co-distribution of native and introduced vascular plants
(Nature Publishing Group, 2013-09)
Species gain membership of regional assemblages by passing through multiple ecological and environmental filters. To capture the potential trajectory of structural changes in regional meta-communities driven by biological ...
Weakening density dependence from climate change and agricultural intensification triggers pest outbreaks : a 37-year observation of cotton bollworms
(John Wiley & Sons Ltd., 2014-08-12)
Understanding drivers of population fluctuation, especially for agricultural pests, is central to the provision of agro-ecosystem services. Here, we examine the role of endogenous density dependence and exogenous factors ...
Unlocking patterns of nature - the marriage of mathematics and ecology
(Stellenbosch : Stellenbosch University, 2015-03)
Professor Cang Hui was born in the ancient capital of China, Xi’an, where the Terracotta Warriors were
unearthed. In 1994, he went to Xi’an Jiaotong University, a C9 League, and obtained his BSc in applied mathematics ...
Zeta diversity as a concept and metric that unifies incidence-based biodiversity patterns
(The University of Chicago Press, 2014-11)
Patterns in species incidence and compositional turnover are central to understanding what drives biodiversity. Here we propose zeta (ζ) diversity, the number of species shared by multiple assemblages, as a concept and ...
An optimization approach to the two-circle method of estimating ground-dwelling arthropod densities
(Florida Entomological Society, 2014-06)
Information on ground-dwelling arthropod densities is important for efficient management
in agro-ecosystems. A method of using paired pitfall traps with different inter-trap distances,
called the two-circle method (TCM), ...
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 ...
Cascade effects of crop species richness on the diversity of pest insects and their natural enemies
(Springer, 2014)
Understanding how plant species richness influences the diversity of herbivorous and predatory/parasitic arthropods is central to community ecology. We explore the effects of crop species richness on the diversity of pest ...
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 ...
Eco-evolutionary feedback and the invasion of cooperation in prisoner's dilemma games
(Public Library of Science, 2011-11-18)
Unveiling the origin and forms of cooperation in nature poses profound challenges in evolutionary ecology. The prisoner's dilemma game is an important metaphor for studying the evolution of cooperation. We here classified ...
