One study was in the New York Bight (USA), one in the North Sea (UK).   COMMUNITY RESPONSE (2 STUDIES) Overall community composition (2 studies): One before-and-after, site comparison study in the New York Bight found that after ceasing sewage sludge dumping, overall invertebrate community composition became more similar to less disturbed sites. One replicated, site comparison study in the North Sea found that overall invertebrate community composition changed but remained different to that of natural sites. POPULATION RESPONSE (2 STUDIES) Overall abundance (1 study): One replicated, site comparison study in the North Sea found that after ceasing sewage sludge dumping, overall invertebrate abundance became similar to that of natural sites. Worm abundance (1 study): One before-and-after, site comparison study in the New York Bight found that after ceasing sewage sludge dumping, abundance of pollution-indicator polychaete worms decreased and became similar to that of natural sites.

One study was in each of Australia, Costa Rica and the USA. COMMUNITY RESPONSE (0 STUDIES)   POPULATION RESPONSE (2 STUDIES) Survival (2 studies): One replicated, site comparison study in Costa Rica found that in waterways with enforced speed limits, fewer spectacled caiman were found dead with boat-related injuries compared to waterways with no speed limits. One replicated study in the USA found that vessels travelling at lower speeds caused fewer catastrophic injuries to artificial loggerhead turtle shells, though vessels with jet motors caused no catastrophic injuries at any speed tested. Condition (1 study): One replicated, site comparison study in Costa Rica found that in waterways with enforced speed limits, fewer spectacled caiman were found with boat-related injuries compared to waterways with no speed limits.
