Information transfer about food locations is not a benefit of group living in the solitary foraging striped mouse (Rhabdomys pumilio)


Schradin, C (2007). Information transfer about food locations is not a benefit of group living in the solitary foraging striped mouse (Rhabdomys pumilio). Journal of Ethology, 25(1):83-86.

Abstract

The benefits of group living have primarily been investigated in species which form permanent groups. There are, however, several species that forage alone but still form groups that share the same territory and nest. One of these group-living solitary foragers is the striped mouse (Rhabdomys pumilio) from the Succulent Karoo in South Africa. I performed field experiments on this species to investigate the hypothesis that mice benefit from group living by exchanging information in social groups about the location and availability of food sources. Presenting additional food sources in the field altered individual foraging decisions. A mouse that found food at one location visited it again the next day; other mice of the same group did not arrive, however. Establishment of permanent feeding stations for 1 week affected individual foraging even 1 week after termination of feeding, a result demonstrating the strong effect trapping can have on the behaviour of study species. Results from this study suggest that information transfer about good food sources was of little importance in the evolution of group living in the striped mouse.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
