Evolution of Behavioural and Ecological Diversity:

Australian Acacia Thrips as Model Organisms

This book presents a novel, ‘model clades’ approach to the study of biodiversification, explicitly integrating behaviour, ecology, taxonomy, phylogenetics, and evolution.

A single lineage of over 250 species (30 genera) of phytophagous thrips that has radiated on Australian Acacia is considered. Nine genera are newly described.

The book explores causes and consequences of behavioural-ecological diversification with special emphasis on the evolution of social behaviour, host-plant use and exploitative behaviours.

Ecological pressures of the arid and unpredictable Australian climate have selected for diverse means of creating, usurping, and co-opting domiciles. Such pressure has generated a positive feedback loop—adoption and modification of new host-plants by some thrips species creates further niches for additional ones.

These thrips exhibit remarkable morphological, behavioural and ecological variation. They can be considered as a microcosm for understanding processes that generate biodiversity among all phytophagous insects, and indeed among all animals.
