Evaluación de la calidad del agua mediante un enfoque múltiple en arroyos de la llanura templada (Argentina, América del Sur) [PDF]
, 2012 We assessed the water quality in two pampean lotic systems (Argentina), the Juan Blanco and Buñirigo streams, subjected to different land uses (i. e., the UNESCO Biosphere Nature Reserve versus industry and agriculture, respectively) through measurements

Macroinvertebrates as indicators of pollution.
Journal of environmental biology, 2005 Various pollution indicators of stream Ban-Ganga have been identified on the basis of presence/absence/numerical abundance at various stations. They have been categorized as pollution tolerant, facultative and pollution intolerant groups in relation with the water quality at different stations of stream.

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.ABSTRACT Urbanization modifies stream ecosystems through changes in land use and water quality, with particularly understudied effects in tropical regions. This study evaluates how the conservation status (reference, restored, and impacted) influences nutrient enrichment and organic matter decomposition—key indicators of ecosystem function—across five ...

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider
Ecological Entomology, Volume 51, Issue 3, Page 547-557, June 2026.In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.
