Algal Biomass Accrual In Relation To Nutrient Availability Along A Longitudinal Gradient In The Upper Green River, Kentucky, Mary Douglas Penick Aug 2010

Algal Biomass Accrual In Relation To Nutrient Availability Along A Longitudinal Gradient In The Upper Green River, Kentucky, Mary Douglas Penick

Masters Theses & Specialist Projects

Nutrient limitation in aquatic ecosystems results from a deficiency in nitrogen or phosphorus levels relative to cellular growth needs. Nutrient limitation of freshwater systems is a function of biotic and abiotic factors. Biotic factors include vascular and nonvascular plant community composition. Abiotic factors include underlying bedrock and land-use activities (e.g. agriculture, septic systems). Nutrient availability directly affects growth, productivity, and community structure of primary producers. The purpose of this study was two-fold: (1) to assess the relationship between ambient algal biomass. and in-stream nutrient levels along the longitudinal course of a river through a transition from weak to well-developed underlying …

Southern Lagoon And Village Of Gales Point, Belize, Ca: Water Uses, Water Quality, And Potential Health Impacts, Rasmi Nair, Ritchie Taylor

Impact Belize

An International Health Service Learning Program, Impact Belize 2010, was conducted by Western Kentucky University. Faculty and students worked closely with Gales Point villagers to gain an insight into the use of Southern Lagoon. The objective of the study was to assess fecal coliform levels in Southern lagoon, its primary and secondary contact use by villagers and its potential impact on health. Study methodology involved collection of water samples, both near shore and offshore, in the lagoon and incubating them using ColiQuant EZ method approved by EPA. A questionnaire was administered to villagers attending the WKU clinic to collect data …
