A survey of aquatic macroinvertebrates in a river from the dry corridor of Nicaragua using biological indices and DNA barcoding. [PDF]
Ecol Evol, 2022 A survey of aquatic macroinvertebrates in Nicaragua using biological indices and DNA barcoding. We obtained excellent water quality in one site, high congruence between tree‐based and similarity‐based techniques, and reported 69–73 operational taxonomic units present in a river from the Central American Dry Corridor. Abstract Aquatic macroinvertebrates
