... e., model differences, climate scenarios, disturbance or dispersal scenarios, and stochasticity as represented by replicated runs). For this purpose, we first estimated simulated total biomass and biomass-based gamma diversity across the landscape, expressed by the Shannon Index (Shannon and Weaver, 1976), at decadal time steps for 2000 to 2100 for each model run (future projections: 4 models × 4 climate scenarios × 10 replicates = 160 runs; disturbance scenarios: 4 models × 4 climate scenarios × 4 disturbance scenarios × 10 replicates = 640 runs; dispersal scenarios: 4 models × 4 climate scenarios × 3 dispersal scenarios × 10 replicates = 480 runs). Subsequently, we estimated average change rates for biomass and Shannon Diversity for the first half (2010-2050) and the second half of the century (2060-2100). ...
... Dies gilt beispielsweise für die Informationstheorie (vgl. Hartley 1928;Shannon und Weaver 1976), für das Information Retrieval (vgl. Salton 1979) oder die Linguistik (vgl. ...
... For α-diversity analysis, Shannon-Wiener diversity Index (Shannon, 1948) was calculated via q2-diversity after samples were rarefied (subsampled without replacement) to 46242 sequences per sample. The Kruskal Wallis test was used to determine if Shannon diversity indexes were significantly different between samples (pairwise comparison) and between the different treatments (sampling site, time, and substrates). ...
... To summarize the extent to which each participant's attention allocation was distributed (as opposed to selective), we calculated the entropy of the proportions of looking at the different dimensions. According to information theory, entropy is a measure of diversity or variety among a set of probabilities or proportions (Shannon & Weaver, 1949). Therefore, the entropy of the proportion of looking at different stimulus dimensions encodes the extent that attention allocation was distributed. ...
... Here, p i refers to the proportion of time the animal spent engaged in the ith behavior [22]. Shannon indices range from 0 (only one behavior is seen) to infinite, and higher scores are provided to observations with greater behavioral richness and high evenness. ...
