Do Urban Rivers Provide Sanctuaryto Macroinvertebrates? A Case Study of an UrbanStretch of the Apies River in Pretoria, South Africa
Summary
Researchers assessed macroinvertebrate community health along an urban stretch of the Apies River in Pretoria, South Africa, evaluating whether urban rivers can provide refuge to macroinvertebrates amid impoundment, channel modification, and pollution from agriculture, mining, and wastewater discharges.
Rivers are the most disturbed freshwater ecosystems, suffering from impoundments, channel modification, and pollution [1].A healthy river plays a crucial ecological and societal role due to its ability to regulate floods, cycle nutrients, provide food, support cultural and recreational values, etc. [2].An increase in anthropogenic activities such as agriculture, mining, wastewater works, industrial activities, and urbanization is threatening the integrity of macroinvertebrate communities of river systems [3,4] by changing river
