Hypothesis
Stream trophic status did not vary throughout the seasons across sites.
Conclusion
Seasonality significantly affects the trophic class and nutrient sensitivity of streams in the Lake Waco/Bosque River Watershed.
Supporting Evidence
- The North Bosque River below the Stephenville WWTP showed the highest nutrient enrichment.
- Chlorophyll a productivity varied significantly between seasons.
- Passive diffusion periphytometers are effective for assessing nutrient responses in streams.
Takeaway
This study looked at how different streams in Texas react to nutrients over time, finding that the time of year changes how much algae grows.
Methodology
The study used passive diffusion periphytometers to measure nutrient limitation and trophic status at eight sites over 18 months.
Limitations
The study faced significant deployment losses due to environmental conditions, which may affect the completeness of the data.
