Inter-group conflict in captive siamangs (Symphalangus syndactylus)


Geissmann, T (2008). Inter-group conflict in captive siamangs (Symphalangus syndactylus). Gibbon Journal, 4:51-55.

Abstract

In this study, I describe the increase in territorial behaviour of siamangs kept in two adjacent cages
after the formation of a new pair. The formation of a new pair resulted in a significant increase of a
form of inter-group agonistic behaviour (“arm-pulling”), which occurred exclusively among animals of
the same sex. The increase in conflicts cannot be fully explained by the simple increase in the number
of these territorial animals, but appears to be directly influenced by the formation of a new pair.

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.
