Environmental forcing reshapes copepod functional diversity in the Northwest Atlantic

The code and dataproducts used for the paper Environmental forcing reshapes copepod functional diversity in the Northwest Atlantic published in the Journal of Plankton Research. Note: The Zooplankton data supplied are the annual mean abundances from the copepod species used in this study. For info on the raw monthly data please contact Catherine Johnson if you have any questions. R code env_calculations_1.R :R code used to extract the environmental variables and processing of ancillary environmnetal variables that are downloaded from the azmpdata library. It is not run directly but sourced from env_indices_calcs_2.R. env_indices_calcs_2.R.: This code takes the downloaded data from azmpdata library and interpolates missing data and produces annual anomalies of the environmnetal variables which are used as descriptor variables for the copepod community data. Trait_FD_calcs_3.R.: RDA_GAMS_4.R.: plots_non_model_5.R.: Data used with these scripts annual_indices_hl2.csv & annual_indices_p5.csv: Annual monthly standardised anomalies (between 1999 and 2021) for each of the environmental variables and the annual PC1 and PC2 scores from the principal component analysis of these variables. Used in RDA_GAMS_4. Annual_spec_hl2.csv & Annual_spec_p5.csv: Mean annual abundance for each of the 38 copepod taxa used in this analysis for the years between 1999-2021. Used in Trait_FD_calcs_3 and RDA_GAMS_4 HL_FD_indices.csv & P5_FD_indices.csv: Annual functional diversity indices, total zooplankton biomass and integrated chlorophyll-a. These data are used to constrct much of the manuscripts plots using the R code plots_non_model_5. Trait_db-1.csv: A list of the Continous, categorical and fuzzy coded traits used to develop the core functional groupings used in this paper.
