Abstract

A study on species composition, relative abundance and habitat association of rodents in Yekoche Forest was carried out from September, 2014 to April, 2015 during both wet and dry seasons. Data were collected using live trap and snap trap. A total of 841 individual of rodents were trapped using both live trap and snap trap. Rodent species such as yellow spotted brush-furred rate (Lophuromys flavopunctatus) (24.5%), African grass rat (Arvicanthis niloticus), (23.5%), Broad beaked dolphins (Pelomys harringtoni) (19.1%), Ethiopian narrow headed rat (Stenocephalemys albicaudata) (20.7%) and house mouse (Mus musculus) (12.1%) were recorded. Most of the rodent species prefer Acacia grassland habitats and agricultural farmland. Bushland and riverine vegetation provided less number of rodent individuals. Highest numbers of rodents were recorded during the wet season (56.8%) than the dry season (43.2%). All age groups were represented in the population of the captured species. Abundance of rodents was significantly differed between dry and wet seasons. The study area was highly affected by human activity, as a result rodents species were reduced. Therefore, community based conservation need to be implemented in the study area. Key words: Habitat association, relative abundance, rodents, species diversity, Yekoche Forest.

Highlights

  • A permanent 4900 m2 live trapping grid was established in each selected habitat types for three consecutive days and nights

  • The selection of different habitats was based on vegetation composition of the study area

  • The number of M. musculus (12.1%) from the present investigation was the least interims of number and diversity

Summary

Introduction

They show great diversity in their ecology, morphology, physiology, behavior and life history strategies. The order Rodentia comprises the largest in mammalian species (Kingdon, 1997). Of the total rodent species of the country, 21% are endemic. Muridae family covers 57 species (84%) of the overall species (Afework and ZCorti, 1997). Rodents are adapted to wide range of environments (Nowak, 1999)
