Abstract
AbstractThe name “miombo” is a vernacular term for the forests in central, southern, and eastern Africa that are dominated by the closely related legume family genera Brachystegia, Julbernardia and/or Isoberlinia. Prescribed burning is a common management practice in most miombo woodland in protected areas that highly influences vegetation structure and composition which in turn influences small mammals' distribution and abundance. This practice if not checked might significantly affect the ecosystems. We investigated the effects of prescribed burning on rodent's ecology in the miombo woodland ecosystem in the Selous game reserve, Tanzania, between July 2018 and June 2020. A total of 473 individuals comprising six rodent species; Acomys ngurui (31.50%), Aethomys chrysophilus (28.96%), Mastomys natalensis (18.82%), Lemniscomys rosalia (14.16%), Mus minutoides (2.33%), Paraxerus flavovittis (0.85%) and two insectivorous shrew species; Petrodromus tetradactylus (3.17%) and Crocidura hitra (0.21%) were captured during 14,112 trap nights. There were no statistically significant differences in the abundance of A. ngurui between burnt and unburnt areas but its abundance was statistically significantly different between seasons. M. natalensis abundance was not statistically significantly different between burnt and unburnt areas or across seasons. The burnt sites had the highest species diversity than the unburnt in both wet and dry seasons. A. ngurui and M. natalensis survival and recruitment between burnt and unburnt sites were not statistically significantly different. The study shows that prescribed burning has an effect on specific species and demographic characteristics both positive and negative.
