Diet Content And Overlap Of Six Species Of Turtle Among The Wabash River, Lori Pierce Jan 1992

Diet Content And Overlap Of Six Species Of Turtle Among The Wabash River, Lori Pierce

Masters Theses

A community of six species of turtles from the Wabash River and its backwaters was studied to determine diet composition of each species and amount of dietary overlap among species. Species studied included: Trionyx muticus, Trionyx spiniferus, and Graptemys ouachitensis in the river; Trachemys scripta and Chrysemys picta in both the river and backwaters; and Chelydra serpentina in the backwaters only.

Trionyx muticus, T. spiniferus, and G. ouachitensis all belong to a guild that specializes on aquatic insects. The highest diet overlap (69.6%) was between the two softshells, T. muticus and T. spiniferus. Coexistence is possible because T. spiniferus ...


A Herpetofaunal Survey Of The Braidwood Dunes And Savanna Nature Preserve, Daniel J. O'Connell Jan 1992

A Herpetofaunal Survey Of The Braidwood Dunes And Savanna Nature Preserve, Daniel J. O'Connell

Masters Theses

A herpetofaunal survey was conducted on two sand prairie areas in Will Co., IL.; The Braidwood Dunes and Savanna Nature Preserve (BD+S), and Sandridge Savanna. Drift fences with pitfall traps, herpetological attractor panels, aquatic hoop traps, and manual collecting were used to sample the two preserves. A species list was compiled, and the habitat preferences and relative abundance of each species present were determined. The species list was compared with the species lists of other Illinois sand areas and the Nebraska sandhills. Guilds represented by the herpetofaunae of each area were also compared.

Seventeen species were recorded at BD ...
