Multi-taxa biodiversity dataset from the Arroyo Canal Candelaria (Santa Fe, Argentina)

This dataset contains multi-taxa biodiversity data collected in the Arroyo Canal Candelaria watershed (southern Santa Fe Province, Argentina). It includes presence–absence records for amphibians, reptiles, birds, and mammals aggregated at the longitudinal unit level (upper, middle, and lower basin), as well as abundance data for benthic macroinvertebrates at six sampling sites across four seasons. The dataset supports the analyses presented in the manuscript: “Multi-taxa evidence of partial ecological recovery in the Arroyo Canal Candelaria system, southern Santa Fe Province, Argentina”.
