A study of the spatial distribution of 3 species of nereid polychaetes (Nereis virens, N. diversicolor and N. succinea) was conducted during fall 1991 in Danish estuarine waters. Results from field data (Kerteminde Fjord/Kertinge Nor and Norsminde Fjord) suggested that pore water sulfide (HS-) acts on the distribution of these species. N. virens was confined to low-sulfidic areas (< 50 µM) while N. succinea was found in high-sulfidic sediments (from 50 to 2000 µM). N. diversicolor, on the other hand, showed a broader distribution with respect to pore water sulfide. Complementary tank experiments indicated that all 3 species preferred non-sulfidic sediments in allopatry, whereas N. diversicolor was excluded from the non-sulfidic compartments of tanks in sympatry with each of the other 2 species. Mortality rates indicated that N. virens was the least sulfide-tolerant species whereas the other species showed some sort of adaptation with respect to pore water sulfide.
