Summary and Directions for Future Research,ems. To give one illustration: Huge tracts of land offered adequate pasture for large-scale sheep-farming during the earlier years of white settlement, usually settled during a favourable period in the secular trend of the rain cycle. The oncoming drier phases and years or real drought caused overpo

So only about 8 % of the Australian fish-species are freshwater. By comparison wi

https://doi.org/10.1007/978-3-658-15926-9 is very far from complete. Many families are inadequately studied. Papers published by the author make this very evident: for example, in 1926 Tillyard knew only 1 genus, with 5 species, of Apioceridae, a family very well developed in Australia; in 1953 the author listed 2 genera with 64 and 6 spec

Only one group, the freshwater mussels, has been studied sufficiently to allow the preparation of a monograph (. & ., 1958) and even here, one genus is still known from the shells alone. Many species are known from only a few shells from a single locality, and while a number of species ha
