Rodents were sampled using the capture-mark-recapture technique along transects in disturbed and undisturbed tropical forest in Cat Tien National Park in south *** transects comprised two strata:traps were placed on the ground and in the canopy 2–12 m above the *** the main transect,which was 1500 m long and located in undisturbed forest,a total of 438 rodents(173 squirrels and 265 murids)of 12 different species(one Scuridae sp.;11 Muridae spp.)were marked between January 2005 and January *** this study site and at another undisturbed tropical forest site in the same area,two species dominated:the rat Maxomys surifer(Miller,1900)and the squirrel Callosciurus flavimanus(Geoffroy,1831).During the study period we observed no significant difference between the average abundances of the two species(4.67±0.86 and 3.1±0.85 individuals per 100 trap nights,respectively)or between the average proportions of resident squirrels and rats(60.0±24.1 and 62.5±11.5,respectively).The number of squirrels that were permanent residents(*** in the same habitat for 1 year)was eightfold the number of rats that were permanent *** addition,there was some synchrony in the daily capture dynamics of squirrels and of *** observed no significant difference in the total abundance of small mammals between the arboreal and ground *** two disturbed tropical forest sites in the same area,however,no such balance between squirrels and rats was observed,and the density of *** was very *** suggest that the relationship between these two dominant species can act as an indicator of the integrity of tropical forest ecosystems in south Vietnam.
