Little is known of the reproductive biology of the endangered sandhill dunnart (Sminthopsis psammophila). This study demonstrates the first captive breeding of the species, defines several important reproductive parameters and documents morphological development of the young. The study confirmed field speculation that S. psammophila is a seasonal breeder and adopts a life-history strategy similar to that of other arid-zone Sminthopsinae. The average (range) interval from mating to birth is 18 (16–19) days.

Daily egg production of the moth Parapediasia teterrella declined over the life-span of the female but egg size remained constant. The absence of water resulted in lower fecundity and early mortality. Egg size and lifetime fecundity showed considerable inter-individual variation and large females produced more and larger eggs than their smaller counterparts. Large females expended greater reproductive effort than small females. Hatching success was negatively related to egg size. In spite of this, large females laying large eggs had higher fitness than small females. I postulate that multiple reproductive strategies within a species, resulting from differences in reproductive effort expended, may explain why expected trade-offs in reproductive parameters (e.g., egg size versus egg number) were not found in this species. Furthermore, I argue that the prevalent interpretation of life-history evolution (that body size is the important determining parameter of life-history parameters) may reflect correlation of body size with reproductive effort, and reproductive effort may be more important in determining the nature of trade-offs between reproductive parameters.
