Quantity Discrimination in Domestic Rats, Rattus norvegicus
Quantity discrimination is a basic form of numerical competence where an animal distinguishes which of two amounts is greater in size. Whilst quantity discrimination in rats has been investigated via training paradigms, rats' natural quantity discrimination abilities without explicit training for a desired response have not been explored. This study investigated domestic rats' ability to perfor...
متن کاملA survey on helminthic infection in mice (Mus musculus) and rats (Rattus norvegicus and Rattus rattus) in Kermanshah, Iran
Parasitic infections of rodents can compromise scientific research as well as the health of the animals and humans. Based on previous studies, infection rate of parasitic helminths is different in various regions of Iran. The current survey was aimed to determine endoparasitic helminths infection in 138 trapped rodents of Kermanshah county, Iran. Mice and rats were trapped using metal snares fr...
متن کاملHome base behavior in amphetamine-treated tame wild rats (Rattus norvegicus).
When a rat treated with amphetamine (0.5-5 mg/kg) locomotes in an unfamiliar environment, there are one or two places which it visits most often. In these one or two places the mean duration of a visit (stop) is the longest, and, compared to other places, the incidence of grooming and rearing are the highest. Since in intact rats these features of place characterize it as a 'home base', it is c...
متن کاملAssociation of intraspecific wounding with hantaviral infection in wild rats (Rattus norvegicus).
The potential for hantaviral transmission among wild Norway rats by wounding associated with aggressive interactions was evaluated using a prospective sero-epidemiological study coupled with a mark-release-recapture survey. There was a significant association between an animal's serological status and the presence of wounds. Longitudinal studies of marked and released animals showed seroconvers...
متن کاملLesions associated with Eucoleus sp. in the non-glandular stomach of wild urban rats (Rattus norvegicus)
Histological lesions associated with Eucoleus sp. infection of the non-glandular stomach were discovered in a wild, urban population of Norway rats (Rattus norvegicus) trapped over a 1-year period in Vancouver, Canada. Four distinct categories of histological lesions in the non-glandular stomach were identified in association with infection in a sample of 183 rats. The apparent prevalence of Eu...
