Phosphorus Levels & Effects on Lake Ecosystems: A Limnology Lab Data Review

This study analyzes the impact of phosphorus levels on organisms in various lakes, focusing on sources, effects, and expectations of high phosphorus environments. Comparison of total phosphorus among sampled lakes in Fall 2004 reveals correlations with production, phytoplankton, light attenuation, and amphipod/copepod populations. The study delves into the sources (e.g., anthropogenic, agricultural runoff) and effects of phosphorus on phytoplankton and fish populations in different lake ecosystems.

  2. BREAKDOWN • Mike- P levels • Marvel- effects on organisms • Rich- lake wide/cumulative

  3. Limnology Lab Data ReviewWater Chemistry-Phosphorus • Comparison of total P among the six lakes sampled during the Fall 2004 Semester • Total P and Dissolved P in the three Adirondacks Lakes sampled • Sources and effects of phosphorus

  4. Expectations • High P levels = high production • High P levels = increased phytoplankton ** • High P levels = increased light attenuation • High P environments = increased amphipod/copepod populations -presence of some indic. of P

  5. Comparison of total P in the five lakes sampled

  6. Total and Dissolved P in Arbutus Lake

  7. Total and Dissolved P in Catlin Lake

  8. Total and Dissolved P in Rich Lake

  10. What are the sources of phosphorus • Anthropogenic • Onondaga Lake – Sewage • Oneida Lake – Agricultural runoff • Iron Trap?

  11. What are the effects of phosphorus ? • On phytoplankton ? • On fish?
