1. The directed-dispersal (DrD) hypothesis constitutes one of the main explanations for the adaptive value of seed dispersal in spatially heterogeneous environments. Traditionally, the DrD hypothesis asserts non-random arrival to specific sites [...]

1. Eutrophication is a major threat for freshwater ecosystems. Submerged aquatic plants (macrophytes) can maintain clear water conditions in eutrophic lakes by competing with phytoplankton for light and nutrients. The interactions between macrop[...]

1. A change in a climate variable may alter a species abundance not only through a direct effect on that species vital rates, but also through indirect effects mediated by species interactions. While recent work has highlighted cases in which in[...]

1. We present a model to quantify tropical forest structure and explain variance in dynamic rates (growth and mortality) that is computationally simple and can be applied to landscape-scale forest inventory and, potentially, remote sensing-deriv[...]

1. Understanding the variation in population abundances requires accounting for the environmental variability and uncertainty on different scales. We developed and evaluated a Bayesian hierarchical model for the inter-annual variation in populat[...]

1. Arctic vegetation tends to be spatially heterogeneous and can have large areas of mixed transition zone vegetation between stands dominated by a single or few species. If plant photosynthesis and growth within these transition zones differs s[...]
