Web-invasion and araneophagy by New Zealand and Australian pholcid spiders. This work is based around the different colony foundation methods and social systems of Ropalidia revolutionalis , R. romandi , R. mackayensis , and R. gregaria all of which occur on campus, often in abundence. Work is at the data-accumulation stage. Polyrhachis includes a number of species that use silk donated by larvae to cooperatively construct nests. Geckos have complex agonistic displays using visual and acoustic channels.
Olfactory cues are also important in their social systems.
The native Gehyra dubia is being displaced by Hemidactylus frenatus in urban Townsville, but remains dominant in woodlands surrounding buildings. Follow-up studies will examine the invader and the mode of interaction between the species. Rowe, R.J. 1978.
