background： A novel approach to modelling individual tree growth dynamics is proposed. The approach combines multiple imputation and copula sampling to produce a stochastic individual tree growth and yield projection system. Methods： The Nova Scotia, Canada permanent sample plot network is used as a case study to develop and test the modelling approach. Predictions from this model are compared to predictions from the Acadian variant of the Forest Vegetation Simulator, a widely used statistical individual tree growth and yield model. Results： Diameter and height growth rates were predicted with error rates consistent with those produced using statistical models. Mortality and ingrowth error rates were higher than those observed for diameter and height, but also were within the bounds produced by traditional approaches for predicting these rates. Ingrowth species composition was very poorly predicted. The model was capable of reproducing a wide range of stand dynamic trajectories and in some cases reproduced trajectories that the statistical model was incapable of reproducing. Conclusions： The model has potential to be used as a benchmarking tool for evaluating statistical and process models and may provide a mechanism to separate signal from noise and improve our ability to analyze and learn from large regional datasets that often have underlying flaws in sample design.

Tracking invasion and invasiveness in Queensland fruit flies： From classical genetics to ＇omics＇

Current Zoology 2015年第3期61卷 477-487页

Three Australian tephritid fruit flies （bactrocera tryoni - Q-fly, bactrocera neohumeralis - NEo, and bactrocera jarvisi - JAR） are promising models for genetic studies of pest status and invasiveness. The long history of ecological and physi- ological studies of the three species has been augmented by the development of a range of genetic and genomic tools, including the capacity for forced multigeneration crosses between the three species followed by selection experiments, a draft genome for Q-fly, and tissue- and stage-specific transcriptomes. The Q-fly and NEo species pair is of particular interest. The distribution of NEo is contained entirely within the wider distribution of Q-fly and the two species are ecologically extremely similar, with no known differences in pheromones, temperature tolerance, or host-fruit utilisation. However there are three clear differences be- tween them： humeral callus colour, complete pre-mating isolation based on mating time-of-day, and invasiveness. NEo is much less invasive, whereas in historical times Q-fly has invaded southeastern Australia and areas of Western Australia and the North- em Territory. In southeastern fruit-growing regions, microsatellites suggest that some of these outbreaks might derive from ge- netically differentiated populations overwintering in or near the invaded area. Q-fly and NEo show very limited genome diffe- rentiation, so comparative genomic analyses and QTL mapping should be able to identify the regions of the genome controlling mating time and invasiveness, to assess the genetic bases for the invasive strains of Q-fly, and to facilitate a variety of improve- ments to current sterile insect control strategies for that species

Aseismic smart building isolation systems under multi-level earthquake excitations： Part II, energy-dissipation and damage reduction

Frontiers of Structural and Civil Engineering 2015年第3期9卷 297-306页

based on the performance results of the previously suggested smart building isolation systems （lst companion paper）, this following study verifies the control effects of the systems from the view point of energy dissipation and damage level metrics. Several different model cases of the strategically isolated multi-story building structures utilizing passive dampers and semi-active resettable devices are analyzed and the energy-based target indices are compared. Performance comparisons are conducted on statistically calculated story/structural hysteretic energy and story/structural damage demands over realistic suites of earthquake ground motion records, representing seismic excitations of specific return period probability. Again, the semi-active solutions show significant promise for applications ofresettable device, offering advantages over passive systems in the consistent damage reductions. The specific results of this study include the identification of differences in the mechanisms by which smart building isolation systems remove energy, based on the differences in the devices used. Less variability is also seen for the semi-active isolation systems, indicating an increased robustness.
