Invertebrates Associated With The Pincushion Moss (Leucobryum Glaucum) And Underlying Soil, Timothy R. Leffler Jan 1988

Invertebrates Associated With The Pincushion Moss (Leucobryum Glaucum) And Underlying Soil, Timothy R. Leffler

Masters Theses

A faunal study of soil invertebrates collected from pincushion moss (Leucobryum glaucum) and underlying soil in a mixed deciduous forest of Charleston, Illinois, was performed because it was discovered that moss habitats have been largely overlooked by investigators.

The results from this study suggest that moss habitats provide a buffer area from the external physical environment, provide protection from predators, a place for oviposition and may be used as a food source. Twenty-seven orders of invertebrates were collected (66,023 individuals). Acarina (57.9%) and Collembola (37.9%) made up the majority of the invertebrate population. Three abiotic factors (temperature ...


Ecology And Interspecific Relationships Of The Painted Turtle, (Chrysemys Picta) In A Marsh-Fen Ecosystem, Eric S. Mcgee Jan 1988

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 made up 15 and 10 percent ...
