Which statement offers the best explanation of how deforesting hubbard brooks watershed (W2) affected the nitrogen cycle?
1. Denitrification rates increased, resulting in a decrease in the export of ammonium
2. Microbial immobilization rates increased, resulting in a decline in stream nitrogen
3. Mineralization rates increased, causing the export of ammonium to increase
4. plant uptake nitrogen stopped, resulting in an increase in the export of nitrate
At a global scale, harmful algal blooms (HABS) are appearing in many places, often new places, and
lasting longer than previously recorded. Across Florida, the occurrence of algal blooms, caused by
various species of phytoplankton, has been intensifying. In the summer of 2016, a state of
emergency was declared because a toxic cyanobacterial bloom occurred in Lake Okeechobee which
spread into and throughout the St. Lucie River and Estuary. Water samples collected during the
bloom helped identify a limiting nutrient.
1. Data from a Burger et al. (2004) indicate that mercury levels in Florida gar, top-level predators, from
Lake Okeechobee were not higher than mercury levels of fish muscle from other locations in the
United States. However, mercury levels in the livers of Florida gar were above the level considered
safe for human consumption.
a. Explain why this is good news for people who fish in Lake Okeechobee.
b. Explain why this is bad news for non-human consumers of fish, and how it…
