Hydrology And Macroinvertebrates As Biological Indicators- An Integrated Study Of The Río Zamora Watershed, Loja, Ecuador, Isabel Ryde
Independent Study Project (ISP) Collection
Water quality and access is under grave threat in Ecuador, yet remains poorly studied. Macroinvertebrates were used as biological indicators to study water quality around Reserva Natural Madrigal del Podocarpus, Loja Province, Ecuador. Data on macroinvertebrates was combined with hydrologic measurements of stream functions. Macroinvertebrate sampling was conducted from 6 sites within the Upper Río Zamora watershed. Geologic outcrops were observed along several roadcuts and stream banks. Hydrologic data was collected by measuring discharge, elevation change, and finding the highest permanent spring. The EPT index (number of EPT individuals and percentage of EPT individuals) and the BMWP/Colombia Index for macroinvertebrates …
The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison
The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison
Independent Study Project (ISP) Collection
The water quality and level of contamination of two rivers in a cloud forest ecosystem in the Mejía region of Ecuador, the Tupí River and the Pilatón River were assessed through benthic macroinvertebrate sampling at various sites along the rivers. Many different biological indices were then used to assess water quality at each site. Pollution in the form of grey water, black water, and petroleum negatively impacted the water quality of the both rivers as they pass through the town of La Esperie. Differences in river structure and size also played a role in determining the prevalence of certain benthic …
Human Impacts On Water Systems: Biological Assessment Of Water Quality In The Bosque Protector Río Guajalito (Bprg) Using Aquatic Macroinvertebrates, Harrison Smith
Independent Study Project (ISP) Collection
Benthic macroinvertebrates have been extensively used as bioindicators for water quality due to their varying sensitivity to a diverse range of impacts on hydrographic sources. In this study a sampling of macroinvertebrates was carried out in the Guajalito and Brincador rivers and a small creek that runs through the private reserve Bosque Protector Rio Guajalito in order to analyze if the health of the rivers has changed in relation to previous studies. The sampling stations were located upstream and downstream of potential sources of disturbance in each of the three streams sampled in order to determine what level of impact …
River Health In Puyo, Ecuador The Use Of Macroinvertebrates As Bioindicators Of Water Quality And Alternatives To Chlorine For Whitening Clothes In The Puyo River Watershed, Allison Rowe
Independent Study Project (ISP) Collection
Fresh water is an important resource in Puyo, Ecuador, a city named after the Kichwa word for ‘cloudy’ in reference to its overcast weather. However, the Puyo River watershed is the most contaminated in all of Pastaza Province. The objective of this investigation was first to evaluate the health of the Puyo River using macroinvertebrate analyses and measurements of chlorine concentrations, temperature, pH, turbidity, velocity, and flow rate. The second objective was to learn about practices used to whiten clothes in Puyo and perceptions of water quality in order to understand the magnitude of bleach pollution and the population’s awareness …
