摘要

Qualitative sampling for Marstonia pachyta (Armored Snail) and Campeloma decampi (Slender Campeloma), two federally endangered species, was conducted at road crossings on Limestone (n = 13), Piney (n = 10), and Round Island ( 7 = 7) creeks, AL, to determine their distribution. Marstonia pachyta was observed at 9 sites oil Limestone Creek and 3 sites oil Piney Creek. The species extended Upstream to river mile 31 on Limestone Creek and river mile 15 on Piney Creek. Haphazard sampling also yielded a greater overall number Of individuals from Limestone Creek than Piney Creek. Marstonia pachyta was not found in Round Island Creek, where it is replaced by M. arga (Ghost Marstonia). Live C. decampi were observed at 12 of the sampled sites (n = 30) in the three streams. Round Island Creek had the greatest percentage of sites with the species (4 of 7) and the highest catch per unit effort. Campeloma decampi extended up to river mile 14.5, 19.3, and 7.8 on Limestone, Piney, and Round Island creeks, respectively. Results extended the known Occurrence or M. pachyta and C. decampi upstream of their previously known ranges. However, careful monitoring and more in-depth studies seem warranted considering the rapid urban and industrial growth within file watersheds of the three streams that they inhabit.
