Code and data for: Fishery catch is affected by geographic expansion, fishing down food webs and climate change in Aotearoa, New Zealand

Please find the R script and data utilised for the manuscript: Fishery catch is affected by geographic expansion, fishing down food webs and climate change in Aotearoa, New Zealand. From Charles P. Lavin, Daniel Pauly, Donna Dimarchopoulou, Cui Liang, Mark John Costello Corresponding author: Charles P. Lavin, charles.p.lavin@nord.no Included is the main R script to complete analyses and re-create figures (file: 'Lavin_et_al_NZ_MTC_MTL_code_final.R'), As well as data files required to run the R script, including: Sea surface temperature anomaly data (file: 'NZ_EEZ_SSTA_1950_2020.csv') extracted from https://psl.noaa.gov/data/gridded/data.kaplan_sst.html The Sea Around Us fisheries catch data for New Zealand's EEZ (accessed 01 May 2022) (files: 'SAU EEZ 554 v50-0.csv' & 'SAU EEZ 555 v50-0.csv'). This data is available open-access at https://www.seaaroundus.org/ FAO fisheries catch data for New Zealand's EEZ (accessed 01 June 203) (files: 'NZ_FAO_catch_data.csv'). This data is available open-access via the FAO's FishStatJ software (https://www.fao.org/fishery/en/topic/166235) Species milieu classifications derived from individual species' FishBase pages (file: 'SAU_spp_milieu.csv'), see https://www.fishbase.se/search.php The list of species contained in sensitivity analyses (file: 'spp_list_Durante.csv'), derived from those species analysed in Durante et al.
