ORDINATION ANALYSIS REVEALS THREE DISTINCT FRESHWATER MUSSEL ASSEMBLAGES CORRELATED WITH RIVER MILE AND AGRICULTURE IN THE BLACK RIVER, MISSOURI AND ARKANSAS
Biogeographical classification and macro-ecology pattern analyses can be useful in understanding distributions of organisms and aid in conservation and management actions. The objectives of this study were to determine if there are distinct freshwater mussel assemblage community patterns along the upstream to downstream gradient of the Black River in Missouri and Arkansas and to determine if there were any environmental parameters that correlated with these community patterns. To meet our objectives, we conducted a Non-Metric Multi-Dimensional Scaling (NMDS) analysis on 63 mussel survey sites sampled between 1990 and 2003 from river mile 50.6 to 265.5. Our NMDS results were then correlated with sub-watershed characteristics (e.g. geology, hydrology, and land use). Our results revealed three distinct Black River mussel assemblages generically representing an upstream Ozark Highlands grouping, a midstream upper Mississippi Alluvial Plain grouping, and a downstream lower Mississippi Alluvial Plain grouping. These distinct assemblages correlated primarily with river mile (0.6315) and river mile plus percent agriculture (0.6690). These results are consistent with our biogeographical expectations that mussel distributions are indirectly related to fish distributions due to the fish and mussel host-parasite relationship, respectively, and are influenced by watershed drainage area.
