Changing restoration rules: exotic bivalves interact with residence time and depth to control phytoplankton productivity Changing restoration rules: exotic bivalves interact with residence time and depth to control phytoplankton productivity
Non-native species are a prevalent ecosystem stressor that can interact with other stressors to confound resource management and restoration. We examine how interactions between physical habitat attributes and a particular category of non-native species (invasive bivalves) influence primary production in aquatic ecosystems. Using mathematical models, we show how intuitive relationships...

Implications of estuarine transport for water quality Implications of estuarine transport for water quality
In this chapter, some implications of estuarine transport for water quality are discussed. This is not an exhaustive review of all physical processes potentially important to water quality in estuaries. Rather, the focus is on (1) some fundamental relationships, concepts, and helpful idealizations (e.g., evolution equations for reactive scalars, transport time scales, scaling and non...

Why are diverse relationships observed between phytoplankton biomass and transport time? Why are diverse relationships observed between phytoplankton biomass and transport time?
Transport time scales such as flushing time and residence time are often used to explain variability in phytoplankton biomass. In many cases, empirical data are consistent with a positive phytoplankton‐transport time relationship (i.e., phytoplankton biomass increases as transport time increases). However, negative relationships, varying relationships, or no significant relationship may...
