Our knowledge of the factors affecting species abundances is mainly based on time-series analyses of a few well-studied species at single or few localities, but we know little about whether results from such analyses can be extrapolated to the community level. We apply a Joint Species Distribution Model to long-term time-series data on British bird communities to examine the relative contribution of intra- and interspecific density dependence at different spatial scales, as well as the influence of environmental stochasticity, to spatio-temporal interspecific variation in abundance. Intraspecific density dependence has the major structuring effect on these bird communities. In addition, environmental fluctuations affect spatiotemporal differences in abundance. In contrast, species interactions had a minor impact on variation in abundance. Thus, important drivers of single-species dynamics are also strongly affecting dynamics of communities in time and space.

Despite such influence, ...
Spatio-temporal dynamics of density-dependent dispersal during a population colonisation De Bona, Sebastiano; Bruneaux, Matthieu; Lee, Alexander; Reznick, David N.; Bentzen, Paul; Lopez Sepulcre, Andres (Wiley-Blackwell Publishing Ltd., 2019)Predicting population colonisations requires understanding how spatio‐temporal changes in density affect dispersal. Density can inform on fitness prospects, acting as a cue for either habitat quality, or competition over ...
Analyzing environmental‐trait interactions in ecological communities with fourth‐corner latent variable models Niku, Jenni; Hui, Francis K. C.; Taskinen, Sara; Warton, David I. (John Wiley & Sons, 2021)In ecological community studies it is often of interest to study the effect of species related trait variables on abundances or presence-absences. Specifically, the interest may lay in the interactions between environmental ...

Deducing self-interaction in eye movement data using sequential spatial point processes Penttinen, Antti; Ylitalo, Anna-Kaisa (Elsevier BV, 2016)Eye movement data are outputs of an analyser tracking the gaze when a person is inspecting a scene. These kind of data are of increasing importance in scientific research as well as in applications, e.g. in marketing and ...
