Book Description
The restoration of tallgrass prairies is often centered on reestablishing the native vegetation structure with only minor efforts directed to the fauna that inhabit these areas. The reinstatement of traditional disturbance regimes of fire and grazing bison is a critical component to the active management of tallgrass prairies, and its subsequent effects on both flora and fauna in remnant prairies is well documented. Understanding the role of small mammal populations and how they are affected by varying grazing and fire management strategies can assist in the holistic evaluation of restoration efforts in sites currently undergoing active restoration. Peromyscus and Microtus species play an important role in the upper tropic level dynamics of tallgrass prairie ecosystems through influencing the vegetation structure via herbivory, predating upon seeds and various invertebrate species and as prey for larger fauna. Mark and recapture data has provided a landscape-scale test for how restored tallgrass prairies with different management strategies recover from stressors and disturbances. Abundance and diversity are correlated with more floristically diverse remnant quality sites. Results indicate that there is a specific response for Peromyscus and Microtus species to varying measures of vegetation composition and precipitation in actively restored and managed tallgrass prairies in Illinois. Seasonal fluctuations in the community composition of small mammals is documented at all sites with a varied assemblage occurring within sites that are grazed by bison. Grazing had no impact on species richness, abundance or diversity on the landscape scale. Peromyscus species' apparent survival in this restored network of tallgrass prairie is dependent on time with a varied recapture probability by sex. Logistic regression models provide managers with an equation by which they can estimate the suitability of a given restoration for small mammal diversity and abundance targets though direct environmental measures.

The Effects of Prescribed Fires in Different Seasons on Small Mammals in a Sierra Nevada Mixed Conifer Forest

Book Description
"Prescribed fire is an important management practice used to restore natural fire regimes in Sierra Nevada mixed conifer forests where fire has been suppressed over the last century. It is not well known, however, how the timing of prescribed fire affects wildlife species. I compared the effects of prescribed fires during the early season (spring and early summer) with those during the late season (late summer and fall) on small mammal populations using model selection and inference methods. ... Lodgepole chipmunk (Neotamias speciosus) movements differed between years, but there was no effect of prescribed fires on their movements (Chapter 1). Deer mouse (Peromyscus maniculatus) movements differed between age groups within years. Prescribed fire treatments did not affect deer mouse movements, except when only adult female deer mouse movements were analyzed. Year effects were more important than fire effects on lodgepole chipmunk densities, total small mammal biomass, deer mouse densities, and deer mouse age ratios (Chapter 2). Prescribed burning had a positive effect on deer mouse pregnancy ratios, and there was only limited support for an effect of year on these ratios. There was essentially no support for different effects of fire depending on the season of fire on total small mammal biomass and deer mouse densities, and only limited support for these effects on lodgepole chipmunk densities, deer mouse age ratios, and deer mouse pregnancy ratios. The prescribed fire treatments differentially impacted small mammal habitat components depending on the season of the fire (Chapter 3). However, there were few significant relationships between these habitat components and deer mouse densities, lodgepole chipmunk densities or small mammal species richness. Overall, year effects often had the greatest influence on the small mammal populations examined, and there were few strong differences between the effects of early season fires and late season fires on these populations."--Abstract.

Indirect Effects of Fire on the Small Mammal Community of a Tallgrass Blackland Prairie Remnant in Texas

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.
