Trout and invertebrate assemblages in stream pools through wildfire and drought

Climate change is increasing the frequency, severity, and extent of wildfires and drought in many parts of the world, with numerous repercussions for the physical, chemical, and biological characteristics of streams. Yet information on how these perturbations affect top predators and their impacts on lower trophic levels in streams is limited.
The top aquatic predator in southern California streams is native Oncorhynchus mykiss, the endangered southern California steelhead trout (trout). To examine relationships among the distribution of trout, environmental factors, and stream invertebrate resources and assemblages, we sampled pools in 25 stream reaches that differed in the presence (9 reaches) or absence (16 reaches) of trout over 12 years, including 8 reaches where trout were extirpated during the study period by drought or post-fire flood disturbances.
Trout were present in deep pools with high water and habitat quality. Invertebrate communities in trout pools were dominated by a va..., Sampling of stream invertebrates, observations of trout, and measurements of stream abiotic factors., , # Trout and invertebrate assemblages in stream pools through wildfire and drought

Spreadsheets (datasets) are organized by type of analyses (multivariate versus univariate) and the data used for specific analyses (Multivariate: non-metric multi-dimensional scaling (NMS), multi-response permutation procedure (MRPP), Indicator Species Analysis (ISA); Univariate: Mixed effects models, structural equation models, linear regression, or Analysis of Variance (ANOVA) and Tukey's HSD test). The initial ReadMe file for multivariate versus univariate analyses shows the focus of analyses, the data file (spreadsheet) used for each analysis, the statistical analysis performed, the figure associated with each analysis, and the number of site-times used in each analysis and, in the case of the univariate analyses, the months and years included in analyses. Two additional spreadsheets include a ReadMe file dealing with the methods and references for assigning traits to collected taxa and a file showi...
