| Abstract | We investigated the role of maternal odors emanating from excretory deposits and/or glandular secretions during the postnatal development of foraging and related behaviors in young Los Talas’ tuco-tucos (Ctenomys talarum), a solitary rodent, under seminatural conditions. During cafeteria tests, we offered them two of the grasses most preferred by adults of this species (bromegrass, Bromus unioloides and panicgrass, Panicum racemosum). We scent marked one dietary option in a treatment group, and the other option in a second treatment group, keeping a third group with no odors as control. Pups did not show to prefer a special grass in particular, and maternal odors showed no effect on the behavioral variables evaluated in this study. When they reached their weaning age, they showed an ontogenetic change in food preferences, where they preferred bromegrass, and maternal odors influenced negatively on the consumption of panicgrass. During dispersal, preference for bromegrass was expressed independently of the presence of maternal odors. Overall, their effect was less pronounced than age’s effect, and it was evident in only a subset of the conducted experiments. This study shows that the influence of maternal odors is not essential for the establishment of feeding or site preferences in this species in seminatural conditions, contrarily to what was observed in other studies performed with social mammal species (i.e., rats and rabbits). It is suggested that other factors (e.g., individual learning) might influence the observed preferences. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
