abstract
Biologists have long been interested in the response of small mammals and their habitat following natural disturbances. The Yellowstone-area fires of 1988 have provided opportunities to study short and long term responses. This study continues investigations conducted in the 1990’s following identical methodology at the same sites now 21 years post-fire. We live trapped 256 Clethrionomys gapperi (Red-backed Vole), 116 Peromyscus maniculatus (Deer Mouse), 44 Tamius minimus (Least Chipmunk), 28 Zapus princeps (Western Jumping Mouse), two Microtus montanus (Montane Vole) and 38 shrews (Sorex ssp.). These results support findings from other investigations regarding the initial early dominance of P. maniculatus in burn areas and C. gapperi in control or non-burn areas, and as time increases since the burn, differences between burn and control sites has decreased. As expected calculated Shannon diversity indices (H’) in 2009 are higher for one of the burn sites than in previous years as the habitat recovers to pre-burn conditions. For example, in 2009 H’ was 0.5796 for the EFB but only 0.2580 for 1991. However, for the WFB H’ was 0.43785 for 2009 compared to 0.5170 in 1991. We have also discovered an interesting twist regarding diversity indices: recent burn and control communities indeed resemble one another more now than immediately after the fire (as anticipated) but most notably when site aspect (east vs. west-facing slopes) is taken into account. note
