“…Lake Tuscaloosa (LT) and Lake Lurleen (LL) are 2 freshwater reservoirs situated in the Black Warrior River basin, Alabama, USA (Ward et al 2005). LT has a surface area of 24 km 2 and a maximum depth of 30 m, while LL has a surface area of 1 km 2 and a maximum depth of 10 m. Samplings and measurements were taken every 1 to 2 wk from December 2007 to November 2008 (LT) and from October 2008 to November 2009 (LL) at a central point in each lake (LT: 33°17' 24.61'' N,87°30' 41.43'' W;LL: 33°17' 27.65'' N,87°30' 40.51'' W).…”

“…The 5 th -order Sipsey River flows through the Coastal Plain of the Tombigbee River basin in west central Alabama (Ward et al 2005) and is one of the few remaining unregulated rivers in the United States (Benke 1990). Although the Sipsey's mean annual discharge is only 24 m 3 /s near our study site, discharge may increase to >200 m 3 /s while inundating much of its floodplain (1-3 km width).…”

“…The floodplain has a bottomland hardwood forest with a dense canopy, where discharge varies daily and annually (Tronstad et al 2005a). More flooding typically occurs in winter and spring than summer and fall, due to higher evapotranspiration during the latter period (Ward et al 2005), a pattern that is common throughout much of the southeastern United States (Benke and Cushing 2005). However, flooding of the lower floodplain elevations occurs during any season and inundation may last for days, weeks, or months.…”

Growth Rates of Chironomids Collected from an Ephemeral Floodplain Wetland

Floodplains are dynamic wetlands that are constantly alternating between aquatic and terrestrial phases. To survive these conditions, aquatic invertebrates must have life history strategies allowing them to take advantage of inundation periods. One such strategy is growing rapidly and completing development before flood waters recede. We measured daily growth rates and development times of 7 chironomid species during April, June, and August using egg masses collected from the Sipsey River floodplain, west central Alabama, USA. Egg masses and resulting larvae were reared under ambient temperatures (18-27°C) and with a natural food source. All successfully reared chironomids were in the subfamily Chironominae. Mean growth rate was 0.28 d -1 suggesting a biomass turnover time of 3 days. Mean development time was 17 days. Temperature affected chironomid development time, with slower rates occurring at the lowest temperature. While many chironomid species appear capable of rapid growth in floodplains when temperatures are >18°C, completion of their life cycle seems likely only if inundation persists at least 2-3 weeks. Longer inundation periods are probably necessary for chironomids to complete their life cycle at colder temperatures in winter and early spring.

The Cahaba River is a largely free-fl owing river system in central Alabama noted for the great diversity of its aquatic fauna. Much of the vertebrate and molluscan faunas have been examined in past studies, but with the exception of the Trichoptera, relatively little is known of the aquatic insect fauna. This study was conducted to fi ll the void left by the absence of mayfl y and stonefl y data. Mayfl ies and stonefl ies were collected from seven sites along a longitudinal gradient on the mainstem Cahaba River from late April 2004 to May 2005. Forty species, 25 genera, and nine families of Ephemeroptera were recorded. For the Plecoptera, 18 species, 10 genera, and four families were found. Six new state records for mayfl ies were recorded.
