April M. H. Blakeslee and James E. Byers. 2008. Using parasites to inform ecological history: comparisons among three congeneric marine snails. Ecology 89:1068–1078.

Appendix B. Field collection sites in North America and Europe for Littorina littorea (LL), L. saxatilis (LS), and L. obtusata (LO), documenting sample sizes and trematode species richness by site.

TABLE B1. Sites are listed north to south using GPS Latitude coordinates. Following this are the number of snails sampled at each site, the number of infected snails at each site, the total species richness at a site, and the adjusted species richness (average + standard deviation) per site. Adjusted species richness is based upon Monte Carlo resampling standardized for sampling effort at 75 individuals (sites with less than 75 individuals are represented by a “*” symbol).
