Abstract
Sīkie zīdītāji ir svarīga pilsētu ekosistēmas biotopu sastāvdaļa. Pētījumi par sīkajiem zīdītājiem ir nepieciešami, lai uzzinātu kāda ir sugu daudzveidība, kādi faktori to ietekmē, kā arī, lai spriestu par pilsētu ekoloģisko stāvokli.
Pētījums tika veikts no 2011. – 2012. gadam. Kopumā dzelzceļa aizsargjoslās tika noķerti 8 dažādu sugu 51 īpatnis. Dominējošā suga A.agrarius. Vislielākais noķerto sugu skaits tika konstatēts pie Ķengaraga dzelzceļa – 9,34 ind./100 sl.dienn. Visā pētījuma laikā dominēja jaunas mātītes.

Small mammals are an important part of the urban ecosystem habitat. Studies on small mammals need to learn what is the diversity of species, what factors influence them, as well as to judge the ecological status of the city. The study was conducted from 2011th - 2012th year. In general railway protection zones were caught 8 different species of 51 specimens. The dominant species is A.agrarius. The greatest number of species caught were found to Ķengaraga railway protection zone 9.34 ind./100 sl.dienn. Throughout the study period was dominated by new females.
