Climate-associated variation in the drivers of benthic macroinvertebrate species-area relationships across shallow freshwater lakes

# Climate-associated variation in the drivers of benthic macroinvertebrate species-area relationships across shallow freshwater lakes ## Description of the data and file structure These are the metadata and codes of the study "Climate-associated variation in the drivers of benthic macroinvertebrate species-area relationships across shallow freshwater lakes", which has been accepted in the Journal of Animal Ecology. Our dataset consisted of 524 freshwater lakes from across the globe sampled at least once from 1974–2021. Data from 505 lakes was contributed by co-authors of this study and included lakes in Denmark, China, Finland, USA, New Zealand , Greece, Mexico and Russia. Most of these data had been published previously (Drake et al., 2011; Hu et al., 2014; Jyväsjärvi et al., 2014; Ntislidou et al., 2018; Cortés-Guzmán et al., 2019; Zhang et al., 2019; Jeppesen et al., 2020; Loskutova, 2020; Jovem-Azevêdo et al., 2022; Wu et al., 2022). We also included data from an additional 19 lakes identified in a Google Scholar literature review using the search terms "shallow lake" AND "zoobenthos" OR "benthic macroinvertebrate". These data come from six publications (Lindergaard & Jónasson, 1979; Takamura et al., 2009; Atobatele & Ugwumba, 2010; Çamur-Elipek et al., 2010; Chakrabarty et al., 2010; Dou et al., 2022). Please see the references in our paper and cited when used the dataset. The archive **species.zip** contains species data for each study, a table describing the average abundance (ind. m-2) of each species in a lake. Note that in this synthesis study, the species symbols, e.g., "sp1, sp2...", only represent the names of species in a lake within a study. That is to say, the same symbols (e.g. sp1) in different studies maybe represent different species. For instance, 'sp1' in Danish lakes represent a species of oligochaeta, but is a bivalve species in Finish lakes. The archieve **env.zip** contains relevant environmental parameters, included lakeno (lake name), year (sampling time), area (lake surface area, km2), waterdepth (sampling depth, m), total nitrogen (tn, mg/L), total phosphorus (tp, mg/L), elevation (m), coordinates (N, S), mesh size (μm), number of sampling sites, replicates per sites, sampler area (cm2), ClimateZ (climate code based on Koppen system, see paper), climate2 (climate zones based on koppen system, see paper) climate (climate group in our study), Missing values are coded as "NA". ## Sharing/Access information Data was also achieved from the following sources: https://github.com/hehuabc/benthic-macroinvertebrates-of-global-lakes ## Code/Software We have also updated 3 code files, which have detailly showed the analysis processes in our paper. All calculation and analysis processes were conducted in R software. Packages of "iNEXT" and "glmmTMB" were mainly used for analysis, and "ggplot2" for graphic work. The figures with high resolution were also attached.
