Abstract EN
The effects of snail density on Biomphalaria alexandrina parasitized with Schistosoma mansoni were investigated.
Laboratory experiments were used to quantify the impact of high density on snail growth, fecundity, and survival.
Density-dependent birth rates of snails were determined to inform mathematical models, which, until now, have assumed a linear relationship between density and fecundity.
The experiments show that the rate of egg-laying followed a negative exponential distribution with increasing density and this was significantly affected by exposure to parasitic infection.
High density also affected the weight of snails and survival to a greater degree than exposure to parasitic infection.
Although snail growth rates were initially constrained by high density, they retained the potential for growth suggesting a reversible density-dependent mechanism.
These experimental data can be used to parameterise models and confirm that snail populations are regulated by nonlinear density-dependent mechanisms.
