Ecology And Interspecific Relationships Of The Painted Turtle, (Chrysemys Picta) In A Marsh-Fen Ecosystem, Eric S. Mcgee
Masters Theses
An ecological study of the painted turtle (Chrysemys picta) was conducted at the Fox River site in Chain O' Lakes State Park in northeastern Illinois from March to September in 1987. Findings were compared to two studies in 1986 concerning the common snapping turtle (Chelydra serpentina) and Blandings turtle (Emydoidea blandingi) also present in the area. Population densities and composition were evaluated to determine the degree of interspecific competition.
Two hundred-forty five turtles were captured in 1986 and 1987. Painted turtles comprised 75 percent of the chelonian population, while Blandings turtles and snapping turtles …

The Southern Redbelly Dace, Phoxinus Erythrogaster (Rafinesque), In Clark County, Illinois, Susan C. Darrow
Masters Theses
Population and feeding ecology of the southern redbelly dace, Phoxinus erythrogaster (Rafinesque), was studied at Rocky Branch Nature Preserve, sections 29 and 30, T12N, R12W in Clark County, Illinois. Three stations designated along the eastern portion of Rocky Branch stream were seined bimonthly July through September, 1987. The length/frequency distribution curve constructed for the 358 dace collected determined Age class 0 to be dace less than 39mm, age classes I and II were indistinguishable because of overlap of fish lengths, and age class III was determined to be dace between 69 and 74mm. Other species encountered in abundance during this …
