Abstract
This dataset accompanies the manuscript titled "Twenty-nine years of monitoring data illustrate variable aquatic insect populations correlated with predators and hydrologic variation in the Everglades" in the journal Ecological Entomology. It includes data and code to generate figures and conduct analyses presented in the paper. Data were collected as part of two long-term biological monitoring programs in the Florida Everglades: the Modified Water Deliveries to Everglades National Project (MWD) and the Comprehensive Everglades Restoration Plan Monitoring and Assessment Project (CERP). These monitoring programs were established to track the populations of fishes and invertebrates important to larger predators (wading birds and alligators) iconic to the freshwater Everglades at a time when (mid-1990s to 2000s) efforts towards ecosystem restoration began. Abundance data on aquatic animals (fishes, insects) were collected using 1-m2 throw traps. Here, our goals were to assess overall trends and drivers of insect densities while examining how conclusions drawn from the datasets depend on spatial and temporal scope of the data analyzed. Data collection was funded and permitted by the National Park Service, with additional funding from the National Science Foundation and permitting by the Florida Fish and Wildlife Consvation Commission and Florida International University's IACUC committee.

Description of the data and file structure
Data were collected using 1-square meter throw traps as part of two long-term biological monitoring programs in the Everglades, the Modified Water Deliveries to Everglades National Park project (MWD; 1996–2025) and the Comprehensive Everglades Restoration Plan Monitoring and Assessment project (CERP; 2005–2024). Details on the methods of these projects are provided in the text of the paper.

File: EVER-LT-insects_full-code.R
Description: This is an R code file of all primary analyses presented in the paper. This file generates sub-datasets by region and project, sets the covariate variables used, and runs the generalized additive models for each taxon and region to (1) determine overall linear trends and (2) effects of biological and hydrologic covariates.
File: EVER-LT-insects_community-code.R
Description: This is an R code file to conduct analyses and generate figures of community metrics presented in the paper. This file generates community sub-datasets by region and project, sets the covariate variables used, and runs the generalized additive models for each metric to (1) determine overall linear trends and (2) effects of biological and hydrologic covariates.
File: Ever-LT-insects_figures-code.R
Description: This is an R code file to generate most of the figures presented in the paper. This file uses the data from the EVER-LT-insects_full-code.R file to generate all individual figure panels, with the exception of the community figures (created in the EVER-LT-insects_community-code.R file), map (data available via the EVERSpatDat package in R), and temperature panels (site level temperature data included in datasets, but figure panels were generated separately using all temperature data).
