Host Influence and Risk of Parasite Recruitment in a Snail-Trematode System at Carpinteria Salt Marsh, 2012-2015 Field Experiment

The project is located at Carpinteria Salt Marsh, part of the University of California Reserve System. The marsh is located at 34.40N, 119.53W, which is near the city of Carpinteria, CA. The "exp_recruitment" data set includes information on site name (site), latitude (lat) and longitude (long) of each site, cage number (cage), the number of egg-transmitted (egginf) and miracidium-transmitted (mirainf) trematode infections per cage, the biomass of snails within a cage (cagebmdens), and the influence (g^3/4) of final hosts that carry egg-transmitted (eggfhi) and miracidium-transmitted (mirafhi) trematodes. The "exp_risk" data set includes information on site name (site), latitude (lat) and longitude (long) of each site, cage number (cage), the length of each snail (length), the mass of each snail (mass), whether the snail was infected with an egg-transmitted trematode (egginf) or miracidium-transmitted trematode (mirainf), the biomass of snails within a cage (cagebmdens), the biomass of snails in the surrounding area (surrbmdens), and the influence (g^3/4) of final hosts that carry egg-transmitted (eggfhi) and miracidium-transmitted (mirafhi) trematodes.
