Suite of hypothesized causal pathways linking broad environmental/ social dynamics Climate and land use change) to intermediate effects (recreation, pesticides, lowered DO, etc.) and proximate mechanisms (increased nutrient, stress to macrophytes, and gravers, reduced flow velocities) that potentially influence algal growth in Florida springs.
