Work at the Danum Valley Field Centre in Sabah, Malaysian Borneo, revealed a guild of arboreal dung beetles found only metres above the forest floor up to the high forest canopy, and that feed on primate dung caught on canopy vegetation. The flight activity, spatial distribution and feeding ecology of this previously unrecorded guild of arboreal beetles is examined, and related to the ecology, behaviour and gut morphology of the primate species resident in the same forest. The dung-relocation behaviour of the Bornean dung beetles is atypical for the genus in which they are found, and breaks with the existing dichotomy ofdung beetle tribes into dung rollers and non-dung rollers. The implications of this discovery are discussed. This work gives a very real indication of how new light can be shed on the ecology of hopical insect communities by studying the strato-orientation of insects in response to conditions in the rainforest canopy, and the importance of canopy work in forming comprehensive descriptions of rainforest arthropod communities.1 aDavis, A., J.1 aHuijbregts, J.1 aKirk-Spriggs, A., H.1 aKrikken, J.1 aSutton, S., L.1 aStork, N., E.1 aAdis, J.1 aDidham, R., K.  uhttps://scarabnet.myspecies.info/ecology-and-behaviour-arboreal-dung-beetles-borneo01347nas a2200181   4500008004100000245005700041210005600098260000800154300001200162490000700174520081900181653006001000100001901060700001601079700001801095700001801113856003401131       1996                        eng d00aInsects in fragmented forests: A functional approach0 aInsects in fragmented forests A functional approach  cJun  a255-2600 v113 aInsects are highly susceptible to the adverse effects of forest fragmentation. It is now beyond any doubt that fragmentation- induced changes in abundance and species richness occur in many insect groups. However, the study of insects in fragmented forests is still in its infancy and lacks real direction. Simple empirical studies are not answering the questions we most want to answer about fragmented systems. Are we in the midst of a mass-extinction crisis? What is the functional significance of the immense insect biodiversity? Does biodiversity loss affect ecosystem functioning? A more focused, functional approach to the study of forest fragmentation is required to move beyond the description of pattern and to determine how changes in insect communities affect ecosystem processes in fragmented forests.10aforest change biodiversity dung beetles forest function1 aDidham, R., K.1 aGhazoul, J.1 aStork, N., E.1 aDavis, A., J.  u<Go to ISI>://A1996UL78800015
