Tailoring biocontrol to maximize top-down effects: on the importance of underlying site fertility.
The degree to which biocontrol agents impact invasive plants varies widely across landscapes, often for unknown reasons. Understanding this variability can help optimize invasive species management while also informing our understanding of trophic linkages. To address these issues, we tested three hypotheses with contrasting predictions regarding the likelihood of biocontrol success. (1) The bi...

متن کاملModelling integrated weed management of an invasive shrub in tropical Australia
1. Where biocontrol programmes for invasive plants are in place, only one-third are fully successful. Integrated weed management (IWM) emphasizes the use of several complementary control measures. 2. We used models of increasing complexity to determine which parameters affect site occupancy of an invasive shrub, Mimosa pigra , in tropical Australia. Two introduced biocontrol agents have spatial...
متن کاملEvent-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces
Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
متن کاملImportance Weighted Autoencoders with Random Neural Network Parameters
Deep generative models for unsupervised learning have recently received considerable attention [1, 2, 3, 4, 5, 6]. These models can find a set of low-dimensional representative latent features that can accurately describe observed data. Furthermore, they can also infer the underlying mechanism that generates, from these features, new data instances similar to the observed ones. In general, thes...
