Digital
Study focussed on indirect effects of horse conch predation on species using pen shells as shelters. Dataset includes multi-year sampling of permanent sites in St. Joseph Bay to measure pen shell dynamics, including recruitment, mortality rates, and growth rates. The community of mobile benthic animals occupying dead Atrina was also measured. Data at other locations (St. George Sound, St. Andrew Bay) is less extensive.
Data are in various forms: some digital, some is published, some would have to be extracted from paper records.
