Like fish, the different human professions involved in the Delta have different habitat preferences:
Lawyers: high turbidity and fear, complex egosystems, either high and cynical levels of expectation, abundant funds
Engineers: high clarity, data-rich nutrient sources, high expectation concentrations, abundant funds
Biologists: thrives on uncertainty and inconclusiveness, extreme biodiversity, highly dynamic ecosystems with complex structure, abundant funds
Spin-specialists: high turbidity, abundance of predators, corrosive water quality, data-free environment, abundant funds
Agency managers: seeks abundant refuge structure, low expectation concentrations, abundant funds
Academics: anywhere where more research is needed (everywhere with any funds).
None of these species is endangered. They all thrive in the Delta, and seem to grow in population with declines in fish populations and Delta flows.
