In: Proceedings Denver, Colorado, Environmental and Engineering Geophysics Society. striatus was found to live in a subsurface with relatively gradual stratigraphical boundaries when compared to surrounding areas.īelaval M, Lane JW, Lesmes DP, Kineke GC (2003) Continuous-resistivity profiling from coastal ground-water investigations: three case studies. Subsurface stratigraphy varied between the areas with and without burrows. striatus were located had a higher porosity (0.36) than areas without crayfish (0.26). Results show subsurface physical differences between crayfish inhabited zones of the wetland and those that do not have crayfish burrows.The Ambiguous Crayfish, Cambarus striatus was found in soils with a hydraulic conductivity of 0.01–0.4 m/day where soils outside of their colony boundary had a hydraulic conductivity of 0.4–1.2 m/day. Hydraulic conductivity of the wetland soils was also determined in the field using slug tests. Soils samples were analyzed for grain size distribution, porosity, and hydraulic conductivity in the lab. Both 2D and 3D geophysical profiles were created. Wetland delineation was also conducted in the field to establish the wetland boundaries. The study utilized field-collected soil cores, electrical resistivity, and ground penetrating radar to map subsurface characteristics at Bartram Forest, Baldwin County, Georgia. This study investigated the soil and hydrogeological characteristics of a wetland and related them to the spatial distribution of crayfish burrows found within it. Since many crayfishes are imperiled by anthropogenic activities, it is important to understand factors that are associated with their distribution within and among wetlands. Crayfish are important in wetland systems because of their function in soil nutrient turnover. ![]()
