Habitat and Geography

Campeloma decisum
are found primarily on the eastern coast of North America, from a few parts of Florida, up to areas of Canada (Dillon et al., 2006).  In Canada, specifically, Campeloma decisum range from Nova Scotia, west to Ontario and Manitoba (Burch and Tottenham, 1980).  In the U.S., Campeloma decisum can be found in the following states: AL, AR, CT, GA, IA, IL, IN, KY, LA, MA, MD, ME, MI, MO, MS, NC, NY, OH, OK, PA, RI, SC, TN, TX, VA, VT, WI, WV (Cordeiro, 2008).  Of the U.S. Campeloma decisum populations, the Indiana populations are the geographical groups that are closest to extinction (Cordeiro, 2008). 

Campeloma decisum
play an extremely important role in their aquatic habitat and food chains, with significant influence on the fish and diving duck food chains (Van Appledorn et al., 2007).  Campeloma decisum reside on the aquatic floors and even below the surface of the floor (Van Appledorn et al., 2007).  Since this is where all populations tend to reside, their burrowing ability is a common behavioral characteristic among all members of the species regardless of geographical location (Van Appledorn et al., 2007).  Campeloma decisum of the Midwest have been found in both lentic and lotic environments (Van Appledorn et. al., 2007).  However, in the Southeast, they prefer to reside solely in Atlantic drainages or river drainages (Dillon et. al., 2006). 
What types of waters do Campeloma decisum prefer?
Aquatic habitats with calcium levels of at least 3mg/liter are favorable, allowing Campeloma decisum to grow healthy shells (Cordeiro, 2008).  Campeloma decisum usually will not be found in environments with a pH level lower than 5, in high salinity waters, or in water with a temperature higher than 45° (Cordeiro, 2008).

All of these factors play a part in determining the habitat that Campeloma decisum are capable of living in.
