Book Description
This study investigated effects of fire on vegetation and small mammals in a tallgrass blackland prairie remnant. At Leonhardt Prairie, vegetation and small mammals were monitored from February 2007 through May 2008 with a burn occurring Fall 2007. Pre-burn, dense litter and vegetative cover accommodated two dominant species, Baiomys taylori and Sigmodon hispidus, with a relative abundance (captures/100 trapnights) of 5.85 and 4.99, respectively. Post-burn, removal of vegetation led to an increase of Peromyscus maniculatus from a relative abundance of 0.12 pre-burn to 5.23 post-burn. Baiomys taylori and Sigmodon hispidus were not captured on burned sections for 7 months, though the unburned section maintained capture rates similar to pre-burn data. Shift in species composition has occurred from Baiomys taylori and Sigmodon hispidus to Peromyscus maniculatus, suggesting short-term fire response of small mammals in tallgrass prairies. This secondary successional cycle of 7 months suggests the prairie's natural fire frequency was high.

Book Description
Based on papers presented at a 1987 symposium, "Fire in North American Grasslands," cosponsored by the Ecological Society of America and the Botanical Society of America, this book represents an important contribution to key unanswered questions concerning the role of fire in grassland ecosystems: How often did fires occur in the past? Were they primarily natural or caused by humans? At what time of year did grasslands normally burn? How should fire be used as a management tool? What constitutes a proper prescribed burning regime both with and without grazing?

Book Description
To assess the interactive effects of prescribed fire on small mammals in these altered ecosystems, we performed a randomized experiment where we applied prescribed fire on 36 of 54 plots. The effects of fire on many small mammal populations and the composition of the small mammal community varied along the invasion gradient, suggesting that fire functions differently in areas dominated by nonnative plants relative to those dominated by native plants. Invasion by this nonnative grass has clearly shifted the composition of faunal communities in semi-desert grasslands and has altered ecosystem processes, therefore reestablishing fire is not likely to be an omnibus solution for restoration.
