Trematode recruitment data from Carpinteria Salt Marsh in California (Parasite Populations project)

Expand/Collapse All

Description

Host density increases parasite recruitment but decreases host risk in a snail-trematode system.

Methods & Sampling

At eight sites at Carpinteria salt marsh, I deployed uninfected snails in 83 5-gallon bucket-size cages. Each cage contained 1, 5, 25, or 100 uninfected snails. Cages were permeable to trematode eggs and miracidia, but not permeable to snails. After 4 months, I measured the influence of snail density on the number of infected snails in each cage (exp_recruitment dataset) and per capita infection risk (exp_risk dataset). I statistically controlled for snail size, the input of trematode infective stages, and snail biomass surrounding the cage. Detailed methods are available in the associated publications.

Data Processing Description

All statistical analyses were run in R (version 3.2.2; R Development Core Team 2015) using the lme4 package.
