Tadpole Stable Isotope Data from Ivory Coast Before and After Defaunation

Comoé National Park, Ivory Coast, provides the geographic scope for this dataset. It contains stable isotope measurements of nitrogen (δ¹⁵N) and carbon (δ¹³C) from tadpoles collected in two temporary ponds. Data was gathered by author Guillaume Demare before (1995, 1996) and after (2014, 2018, 2019) civil wars that caused large mammal loss.

Use Cases

• Modeling the impact of defaunation on aquatic nutrient dynamics based on δ¹⁵N and δ¹³C isotope shifts.
• Analyzing taxon-specific isotopic responses to environmental change based on the described linear models.
• Assessing interannual isotopic variation to distinguish directional change from natural fluctuation.
• Comparing pre-war and post-war ecological conditions in two specific pond sites (A and H).

Strengths

• Data spans a 24-year period, covering five distinct sampling years (1995, 1996, 2014, 2018, 2019).
• Includes precise geographic coordinates for two sample ponds (Pond A: 8.7259 N, 3.8425 W; Pond H: 8.7552 N, 3.7775 W).
• Analysis code ('analysis_isotopes.R') is provided alongside the data, supporting reproducibility.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (130.6 KB), indicating a limited sample scope.

Collection Method

Tadpoles were collected from ponds, euthanized, preserved, and analyzed with a THERMO/Finnigan MAT V isotope ratio mass spectrometer at the Museum für Naturkunde, Berlin.
