The study also attempted to identify arthropods consumed by the small mammals, and to compare the use of arthropods with their relative abundance to ascertain their importance to small mammals on the sites. In the 2 years, 27,299 snap trap-nights and 596 pitfall trap-nights were recorded, and 3,487 individual mammals of 9 species were captured. The post-1972 sites had greater numbers but fewer species of small mammals than did the pre-1972 site and the unmined site, with Microtus pennsylvanicus accounting for 86% of all captures. The pre-1972 mined site had lower total numbers, but more species, present than did the other sites; Blarina brevicauda was the most numerous species, accounting for 62% of all captures. The unmined old field was intermediate in total numbers caught per unit effort, and had moderately high populations of Microtus and Blarina. The mined sites resembled unmined land in early stages of vegetational succession. Quantification of arthropods consumed by the mammals could not be achieved, but both B. brevicauda and Peromyscus maniculatus consumed arthropods as a large part of their diet, with all digestive tracts examined containing arthropod parts. Only 9.5% of the M. pennsylvanicus examined contained arthropod parts. The comparison of arthropod use with relative abundance could not be made, but the vegetation structure was believed to be more important than the presence of any particular arthropod group in limiting the distribution of small mammals.</p> 1980 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1235495236 http://rave.ohiolink.edu/etdc/view?acc_num=osu1235495236 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
