5 orders of magnitude in concentration for each DFAA solution following its release but before contact with mud snails much beyond the perimeter of the inner test arena.
We examined the DFAA dynamics between estuarine water and two mud snail prey species.
Total DFAA fluxes from clams and fiddler crabs were calculated from the molar quantities of the individual amino acids released in a given period of time (Table 3).
We compared individual DFAA concentrations of clam mantle and fiddler crab body fluids (Table 4).
To distinguish between the influences of DFAA and other potential chemical effluxes from prey, we introduced solutions mimicking the amino acid ratios and total concentrations released from injured hard clams and fiddler crabs (mixtures; Table 4).
We examined the effects of chemical composition by reformulating the injured prey DFAA mixtures into blends and adjusting their delivery.
To elucidate the roles of DFAA concentration and fluid input rate in the attraction of mud snails to stimulant sources, we focused on variations of these parameters while holding DFAA composition constant.
For mud snails, DFAA solutions differing in composition and concentration are equally attractive when released at a constant flux, the product of concentration and fluid input rate.
With the exception of crustaceans and teleost fishes, DFAA uptake by marine organisms is nearly universal.
