The Sierra Lakes Inventory Project: Non-Native fish and community composition of lakes and ponds in the Sierra Nevada, California
The Sierra Lakes Inventory Project (SLIP) was a research endeavor that ran from 1995-2002 and has supported research and management of Sierra Nevada aquatic ecosystems and their terrestrial interfaces. We described the physical characteristics of and surveyed aquatic communities for > 8,000 lentic water bodies in the southern Sierra Nevada, including lakes, ponds, marshes, and meadows. We also created digital map layers for these water bodies when such layers did not exist. The original objective of SLIP was to describe impacts of non-native fish on lake communities, but SLIP data has subsequently enabled study of additional ecological issues, including regional amphibian declines and their impacts on communities, and impacts of non-native fish on terrestrial species. In addition, these data are being used to develop fish removal efforts to restore aquatic ecosystems and recover endangered amphibians. The SLIP data is stored in a relational database that collectively describes water bodies (e.g., depth, elevation, location), surveys (conditions, effort), and communities (including approximately 170 fish, amphibian, reptile, benthic macroinvertebrate, and zooplankton taxa).
Throw trap and electrofishing data collected during 1996–2022 from the Everglades, Florida, United States for the publication "Contrasting invasion histories and effects of three non-native fishes observed with long-term monitoring data"
This dataset was used to analyze the effects of three non-native fishes in the Florida Everglades for a publication in the journal Biological Invasions. The dataset incorporates plot-level mean densities (# of individuals per square meter) of common aquatic animals collected during 1996–2022 from 17 sites across three regions of the Everglades: Taylor Slough, Shark River Slough, and Water Conservation Area 3A. Prey species included are nine common small fishes and three common decapod species (two crayfish species and grass shrimp). The dataset includes throw trap data on three predator taxa: African Jewelfish (Hemichromis letourneuxi), Mayan Cichlids (Mayaheros uruphthalmus), and sunfishes (Lepomis spp.). Annual indices of mean wet season electrofishing catch-per-unit-effort of Asian Swamp Eels (Monopterus albus/javanesis), Mayan Cichlids, sunfishes, and the three other large 'top predator' fishes (Amia calva, Lepisosteus platyrhincus, Micropterus salmoides) are included for plots where electrofishing was performed from 1997-2021. Hydrologic measures used in analyses and R code used to conduct analyses are also included.
Tropical range extending herbivorous fishes gain foraging benefits by shoaling with native temperate species
<p>Data1.csv contains the data to analyze the abundance of fish herbivore individuals as a function of the species and the type of shoal. </p> <p>Data2.xlsx contains the data to analyze the foraging activity of the herbivorous fish found in our study. We explored the relationship between bite rates per fish min-1 and the species, shoal type and shoal size. </p> <p>Data3.xlslx contains the data to analyze the shoaling configurations based on species origin. </p> <p>Minguito-Frutos_etal.R contains the R reproducible code to run all the analyses carried out in this study. </p> <p>Species_coocurrence_based_associations.R contains the reproducible R code to run the analyses to explore the strength of mixed-species associations between herbivorous fish. </p> <p>-------------------------------------------------------------------------------------------------------------------------------------------</p> <p>Data1.csv, Data2.xlsx, Data3.xlslx, and Minguito-Frutos_etal.R contains the data and code used before submitting this work. </p> <p>-------------------------------------------------------------------------------------------------------------------------------------------<br><br>Minguito_Frutos_etal2025_SR_Rscript, Data_Rev_SR, and Data2_Rev_SR contain the data and code derived from the last submission to Scientific Reports. In this latest version, we modified our analyses of fish foraging activity that now evaluate: (i) the frequency and size of mixed-species shoals based on the origin of the species examined (using data in Data2_Rev_SR), (ii) the strength of pair-wise associations between native and range-expanding species (using Species_coocurrence_based_associations.R), and (iii) how the foraging activity of native and range-extending fishes was shaped by the composition and size of the shoals (using data in Data_Rev_SR). </p>

FIGURE 4 in Drastic reduction of the functional diversity of native ichthyofauna in a Neotropical lake following invasion by piscivorous fishes
FIGURE 4 | Temporal changes in species richness (dashed lines) and functional richness (FRic; continous lines) of the ichthyofauna from Carioca Lake, Middle Rio Doce basin, state of Minas Gerais, considering two scenarios: "all species", including native and non-native; and "only native species" (left figures). Plotted values expressed as a proportion to the maximum richness. The arrows represent the first records of the introduced piscivorous Cichla kelberi (in 1985) and Pygocentrus nattereri (in 1992) in the system. The upper plots represent the functional space (only two dimensions for simplify visualization), with polygons indicating the proportion filled by the set of species (FRic) in each year. Right figures illustrate the functional space showing the position of each species. Green and blue colors indicate, respectively, the native and introduced species, and crosses indicate native species extirpated from the lake. Codes at the ends of the arrows are the most important ecomorphological traits for each axis of the PCA (for functional trait and species codes, see Tab. 1 and Tab. S2).
