🧪 Pesticide Use vs. Amphibian Population (1990–1995) This dataset captures the annual pesticide usage in the United States and the average population index of amphibians during the same period. 🔸 Data Format Year pesticide_Value (t) Amphibia (population index) 1990 400,522.34 271.04 1991 395,079.01 284.17 1992 401,883.08 191.76 1993 390,543.09 356.56 1994 425,922.68 256.33 1995 423,201.53 239.85 pesticide_Value: Annual pesticide use in metric tons (t), based on FAOSTAT data. Amphibia: Average population index of amphibians, derived from the Living Planet Database (LPD). 🔍 Purpose This table allows for: Observing trends or correlations between pesticide use and amphibian populations. Supporting ecological impact analysis and environmental policy research. Use in time-series plots or regression modeling. 📌 Notes Population index values are normalized; they do not represent absolute numbers but relative trends. Further statistical analysis is needed to infer causation.
