Changes in Macroinvertebrate Community Structure Associated with Land Use in Sierra Nevada de Santa Marta, Colombia

Urban Farm DB summary

This study evaluated aquatic macroinvertebrate community structure in the Ranchería River, Colombia, across conserved, urban/agricultural, and mining zones during the dry season (January–March 2021). Urban/agricultural zones showed the lowest richness (35 genera) and were characterized by disturbance-tolerant species, particularly Melanoides. Land use types constituted the primary driver of community structure, with a 24.1% pure effect, exceeding physical, chemical, and land cover variables.
