@article{4139, abstract = {Pilot studies in England by Stopka and Macdonald revealed that allogrooming in the Old World wood mouse, Apodemus sylvaticus, is a commodity that males can trade for reproductive benefits with females. This study, which used a combination of field study and observations in experimental enclosures, revealed that specific experimental conditions such as group-size and sex-ratio manipulations have a significant effect on the pattern of allogrooming exchanged between individuals. Furthermore, females from the Czech population were more likely to associate with each other as revealed by the clustering of activity centers of females (i.e., as opposed to almost exclusive ranges in English populations), and also by the higher intensity of allogrooming exchanged between females (i.e., virtually lacking in the previous experiment with English mice). Therefore, geographic variation and specific social conditions seem to be important driving factors for allogrooming behavior. Together with changes in overall grooming patterns, allogrooming between males and females remained invariably asymmetrical over all four experimental groups (i.e., two conditions for each sex) in that males provided more allogrooming to females than they received from them.}, author = {Polechova, Jitka and Stopka, P.}, issn = {0008-4301}, journal = {Canadian Journal of Zoology}, number = {8}, pages = {1383 -- 1388}, publisher = {NRC Research Press}, title = {{Geometry of social relationships in the Old World wood mouse, Apodemus sylvaticus}}, doi = {10.1139/z02-128}, volume = {80}, year = {2002}, }
