The Impact

Zebra mussels (Dreissena polymorpha) have altered the structure of invaded ecosystems and exhibit characteristics that suggest they may influence ecosystem processes such as nitrogen (N) cycling. We measured denitrification rates seasonally on sediments underlying zebra mussel beds collected from the impounded zone of Navigation Pool 8 of the Upper Mississippi River. Denitrification assays were amended with nutrients to characterize variation in nutrient limitation of denitrification in the presence or absence of zebra mussels. Denitrification rates at zebra mussel sites were high relative to sites without zebra mussels in February 2004 (repeated measures analysis of variance (RM ANOVA), p = 0.005), potentially because of high NO3–-N variability from nitrification of high NH4+ zebra mussel waste. Denitrification rates were highest in June 2003 (RM ANOVA, p < 0.001), corresponding with the highest NO3–-N concentrations during the study (linear regression, R2 = 0.72, p < 0.001). Denitrification was always N-limited, but sites without zebra mussels showed the strongest response to N amendments relative to sites with zebra mussels (two-way ANOVA, p ≤ 0.01). Examining how zebra mussels influence denitrification rates will aid in developing a more complete understanding of the impact of zebra mussels and more effective management strategies of eutrophic waters.

The suitability of the Eurasian zebra mussel, Dreissena polymorpha, as prey for the common map turtle, Graptemys geographica, was tested under laboratory conditions. The turtles, which were reared in captivity without contact with molluscs, readily consumed zebra mussels in every feeding trial. Mussels were ingested whole. Repeated exposure to zebra mussels in successive trials did not increase consumption rates (ca. 11 mussels/turtle per day), suggesting that the turtles required little time to recognize and efficiently utilize zebra mussels as prey. The turtles were offered zebra mussels ranging from 4 to 34 mm in length and consumed mussels as large as 32 mm, but mussels larger than 25 mm were consumed at lower rates. Turtles consumed lower numbers of zebra mussels in the presence of an alternative prey, the prosobranch snail Bithynia tentaculata, which is common in map turtle habitats in the Great Lakes – St. Lawrence River system. Populations of map turtles and zebra mussels are sympatric in the upper St. Lawrence River, Lake Champlain, the lower Great Lakes, and the upper Mississippi River basin. Our results suggest that map turtles may forage on zebra mussels in nature, but zebra mussels will be important prey only when preferred or more profitable prey are scarce.
