Metaphyton (filamentous algae and duckweeds) can often dominate areas within backwaters and cause undesirable conditions. Recent studies have begun to look at metaphyton dynamics, with a special attention toward the role of nutrients.

The effects of river nutrient concentrations on metaphyton, submersed aquatic vegetation and dissolved oxygen across a connectivity gradient. The study focuses on spatial patterns. The research was published by Houser et al. in 2013. (Abstract)

Temporal evaluation of factors influencing metaphyton biomass, distribution and composition within Upper Mississippi River backwaters. The study follows up on the previous study to better understand temporal patterns within a year. The research was published by Giblin et al. in 2013. (Abstract
