''Dasymys'' is a genus of water rats in the rodent subfamily Murinae, the Old World rats and mice. The genus is endemic to Africa.〔(Monatsb. K. Preuss. Akad. Wiss., Berlin: 12. ) ''In'': Wilson, D. E. & D. M. Reeder. (eds.) 2005. ''Mammal Species of the World. A Taxonomic and Geographic Reference'' (3rd ed). Johns Hopkins University Press. 2005.〕 These rats are wetland habitat specialists, occurring in marshy areas with wet ground and thick vegetation, such as swamps and vleis. They swim well. They are nocturnal and solitary.〔Mullin, S. K., et al. (2004). (Skull size and shape of ''Dasymys'' (Rodentia, Muridae) from sub-Saharan Africa. ) ''Mammalia'' 68(2-3), 185-220.〕 Species are more common in the northern regions of Sub-Saharan Africa, likely because their wetland habitat is more degraded in southern regions.〔Mullin, S. K., et al. (2005). (The distribution of the water rat ''Dasymys'' (Muridae) in Africa: a review. ) ''South African Journal of Science'' 101(3), 117-24.〕 The genus is not well studied and its taxonomy is not clear. The number of species and their relationships have only been tentatively determined.〔 Species include: *''Dasymys alleni'' – Glover Allen's dasymys *''Dasymys cabrali'' – Crawford-Cabral's dasymys *''Dasymys foxi'' – Fox's shaggy rat *''Dasymys incomtus'' – African marsh rat *''Dasymys montanus'' – Montane shaggy rat *''Dasymys nudipes'' – Angolan marsh rat *''Dasymys robertsii'' *''Dasymys rufulus'' – West African shaggy rat *''Dasymys rwandae'' – Rwandan dasymys *''Dasymys shortridgei'' *''Dasymys sua'' – Tanzanian dasymys ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「dasymys」の詳細全文を読む スポンサード リンク
