Collection in 2003


The 2003 field season saw us trek across the United States twice in an effort to flesh out the biogeography of the freshwater dinoflagellates. In March, we travelled 4500 miles to the Lower Rio Grande Valley of Texas via the oxbow lakes of the Mississippi River through Kentucky, Tennessee, Mississippi, and Louisiana. We returned via west-central Texas, southwest Oklahoma, and Arkansas. Despite the early season, we met with success, especially in Arkansas. This August we put some 6700 miles behind us via Nebraska, Wyoming, Utah, Idaho, Washington, returning via Montana, North Dakota, Minnesota, Wisconsin, and Michigan. In addition to dozens of reservoirs and marshes, we sampled high altitude (above 7000 ft.) playa lakes in WY, a glacial lake in WA, prairie potholes in ND, black water (peat) of MN, and the brown water of the Upper Peninsula of MI. The UP was every bit as diverse as anticipated while the alkali conditions of the prairie potholes may have contributed to a dearth of specimens there. More recently in September, we obtained our first Dinos from West Virginia.
