General Information ------------------ Data and Code for "Dispersal increases spatial synchrony of populations but has weak effects on population variability: a meta-analysis" Authors: Qi Yang, Pubin Hong, Mingyu Luo, Lin Jiang, Shaopeng Wang* Data & File Overview -------------------- ### File list: Script.R: this file contains code necessary for analyses and all figures (including the Supplementary Information) ##Data synchrony.csv: this file contains 101 individual effect sizes and covariates information for the analysis of dispersal-synchrony relationship local.csv: this file contains 91 individual effect sizes and covariates information for the analysis of dispersal-local-variability relationship regional.csv: this file contains 75 individual effect sizes and covariates information for the analysis of dispersal-regional-variability relationship All.csv: this file contains estimated mean effect sizes for different categories of discrete covariates synchrony_index.csv: this file contains 4*45 individual effect sizes for different synchrony measure and effect size indices local_index.csv: this file contains 2*45 individual effect sizes for different local variability measure ##Following are explanations of columns in above data files: #Shared column names in synchrony.csv & local.csv & regional.csv Article_ID: Unique identifier for article Factor.Level: Treatment level of manipulated variable(s) besides dispersal rate Sample.Level: A unique numeric ID number for each different combination within multi-factorial experiment design (e.g., dispersal*PH) Art_set: The combination of Article_ID and Factor.Level Art_sam: The combination of Article_ID and Sample.Leve Dispersal.Level: Treatment level of dispersal within each factor level Treat.rate: Dispersal rate in treatment group Treat. mean/var/n: synchrony/local/regional variability value, corresponding variance across replicates and number of replicates for each treatment group Con. mean/var/n: synchrony/local/regional variability value, corresponding variance across replicates and number of replicates for each control group taxa: terrestrial animals (Animal_T), aquatic animals (Animal_A), aquatic bacteria (Bacteria_A), aquatic plant (Plant_A), and aquatic protist (Protist_A) diversity: single-species, single-trophic, multi-trophic EH (environmental heterogeneity): HOM: totally homogeneous; SPA: only spatially heterogeneity; TEM0: uncorrelated temporal pulse; TEM-: asynchronous temporal pulse; TEM+: synchronous temporal pulse Patch_num: number of patches for each experimental unit. 1: two patches; 0: >2 patches perturbations: A: abiotic perturbation; B: biotic perturbation; N: no perturbation time: short: 2.5 - 45 generations; long: 120 - 1000 generations. yi: individual effect size (raw mean different for synchrony.csv; log response ratio for local.csv and regional.csv) vi: variance for effect size v1-v.....: the variance-covariance matrix constructed to account for the non-independence of sharing a common control #Shared column names in synchrony_index.csv & local_ibdex.csv "Metrics" in synchrony_index.csv: D.r: raw mean difference in the mean correlation coefficient of population growth rates; D.x: raw mean difference in the mean correlation coefficient of population sizes D.phi: raw mean difference in the covariance-based index; LRR.phi: log response ratio for the covariance-based index "Metrics" in local_index.csv: CV.m: local variability measured by the simple arithmetic mean of coefficient of CV across patches; CV.w:local variability measured by an average of CV weighted by the population biomass of each patch yi: individual effect size calculated based on different "Metrics" vi: variance for effect size v1-v.....: the variance-covariance matrix constructed to account for the non-independence of sharing a common control #Column names in All.csv Variable: names of different discrete covariates Cat: different categories of discrete covariates N.syn/loc/reg: sample sizes of different categories in dispersal-synchrony/ local stability /regional stability analyses b.syn/loc/reg: estimated mean effect sizes for different categories in dispersal-synchrony/ local stability /regional stability analyses pval.syn/loc/reg: p values of estimated mean effect sizes in dispersal-synchrony/ local stability /regional stability analyses ci.lb.syn/loc/reg: lower bound of confidence intervals for estimated mean effect sizes in dispersal-synchrony/ local stability /regional stability analyses ci.ub.syn/loc/reg: upper bound of confidence intervals for estimated mean effect sizes in dispersal-synchrony/ local stability /regional stability analyses ano.syn/loc/reg: results of Tukey’s all-pair comparisons for estimated mean effect sizes in dispersal-synchrony/ local stability /regional stability analyses Methodological Information -------------------------- Session infor generated by R R version 4.1.0 (2021-05-18) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 10 x64 (build 17134) Matrix products: default locale: [1] LC_COLLATE=Chinese (Simplified)_China.936 LC_CTYPE=Chinese (Simplified)_China.936 [3] LC_MONETARY=Chinese (Simplified)_China.936 LC_NUMERIC=C [5] LC_TIME=Chinese (Simplified)_China.936 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] multcomp_1.4-17 TH.data_1.0-10 MASS_7.3-54 survival_3.2-11 mvtnorm_1.1-2 ggsci_2.9 ggpubr_0.4.0 [8] lemon_0.4.5 ggplot2_3.3.5 cowplot_1.1.1 metafor_3.0-2 Matrix_1.3-3 loaded via a namespace (and not attached): [1] zoo_1.8-9 tidyselect_1.1.1 xfun_0.24 purrr_0.3.4 splines_4.1.0 haven_2.4.1 lattice_0.20-44 [8] carData_3.0-4 colorspace_2.0-2 vctrs_0.3.8 generics_0.1.0 utf8_1.2.1 rlang_0.4.11 pillar_1.6.2 [15] foreign_0.8-81 glue_1.4.2 withr_2.4.2 DBI_1.1.1 readxl_1.3.1 lifecycle_1.0.0 plyr_1.8.6 [22] munsell_0.5.0 ggsignif_0.6.2 gtable_0.3.0 cellranger_1.1.0 zip_2.2.0 codetools_0.2-18 labeling_0.4.2 [29] knitr_1.33 rio_0.5.27 forcats_0.5.1 curl_4.3.1 fansi_0.5.0 broom_0.7.8 Rcpp_1.0.7 [36] scales_1.1.1 backports_1.2.1 abind_1.4-5 farver_2.1.0 gridExtra_2.3 digest_0.6.27 hms_1.1.0 [43] stringi_1.6.1 openxlsx_4.2.4 rstatix_0.7.0 dplyr_1.0.7 grid_4.1.0 mathjaxr_1.4-0 tools_4.1.0 [50] sandwich_3.0-1 magrittr_2.0.1 tibble_3.1.2 crayon_1.4.1 tidyr_1.1.3 car_3.0-11 pkgconfig_2.0.3 [57] ellipsis_0.3.2 data.table_1.14.0 assertthat_0.2.1 R6_2.5.0 nlme_3.1-152 compiler_4.1.0
