Invertebrate photographs and taxonomic information from: Nuance in the narrative of a brown poison frog: Environmental alkaloids and specialized foraging in a presumed toxin-free and diet-generalized species

In poison frogs (Dendrobatidae), conspicuous colors have evolved repeatedly in tandem with high numbers and quantities of skin toxins (alkaloids). Here, we focus on an inconspicuously-colored species—Silverstoneia flotator—which has long been deemed toxin-free and thought to forage opportunistically on mites and ants. Both assumptions have received some empirical support, but there is also evidence that predators avoid S. flotator. In a Panamanian S. flotator population, we sampled invertebrates in frog diets and the surrounding environment (using Berlese and pitfall traps) and screened for skin, dietary, and environmental alkaloids using untargeted metabolomics. We found that while the frogs are opportunistic consumers of mites and ants, they display preferences at finer taxonomic scales (for symphypleonan springtails and Pheidole ants). We also annotated 64 skin compounds as alkaloids, 38 of which were present in the environment. One alkaloid present in the skin and environment is lik..., All stomach and environmental invertebrates were photographed under a Nikon light stereomicroscope and rendered as TIF files. , , # Invertebrate photographs and taxonomic information from: Nuance in the narrative of a brown poison frog: Environmental alkaloids and specialized foraging in a presumed toxin-free and diet-generalized species

## Description of the data and file structure

Invertebrate_Summary_Tables.zip Included in this compressed folder are word documents with tables that have the consensus identifications (from the xlsx files, see descriptions below), but these tables are further curated and thus more easily digestible.

Invertebrate_Identifications_Metabolomic_Set.zip Included in this compressed folder are xlsx documents containing all identifications of the invertebrates used in metabolomic analyses for this study, as well as consensus identifications. Importantly, strikethroughs represent identifications that were ruled out (deemed incorrect) after third-party arbitration, and blank cells means that the source (...,
