“…Data previously collected from the same plots at Big Gibber in April and Bridge Hill Ridge in June 1982 were used for a comparative analysis to assess the degree of change in the 5 years from 1982 to 1987. March to June was the time chosen for the surveys because this period lies outside the breeding season of the species to be monitored on the mining path (Kemper 1977(Kemper , 1979Strahan 1983; B. J.

Changes in small mammal succession along a forested coastal dune system in the Myall Lakes National Park, New South Wales, during 15 years of regeneration after sand mining, were determined by surveys in 1982 and 1987. The results clearly demonstrate a wave of succession moving along the mining path, and confirm that over the intervening 5 year period to 1987, small mammal succession has followed a path indicated by that of the 1982 chronosequence. The house mouse, Mus musculus quickly recolonizes disturbed areas, and peak abundance occurred on plots with a regeneration age of 3.7 years in 1982 and 3.4 years in 1987 (i. e. the 3.0-4.5 age elass). Colonization by the New Holland mouse, Pseudomys novaehollandiae was first recorded on plots with 4.6 years regeneration in 1982 and 5.4 years in 1987. Peak Pseudomys numbers occurred on plots in the 7.5-9.0 age class tn both 1982 and 1987. The common dunnart, Sminthopsis murina appears to be the third species to enter the succession. This modified primary succession closely resembles the mammalian secondary succession following fire where additional evidence suggests that the use of chronosequence analysis may also be appropriate.

A total of 291 P. novaehollandiae were observed during a 4-y study in the Nelson Bay and Smith Lake regions of New South Wales. Reproductive organs were examined from males and females, May 1972-May 1974; reproductive condition of females was noted during a CMR study, August 1974-July 1976. Breeding seasons (conceptions and births) occurred between August and early January (4-5 months) in the first 3 years and between September and March (7 months) in the last year. Second-year females produced three or four litters in short seasons, four or five litters in the long season and up to 20 offspring per season. First-year females produced one litter in short seasons and one or two litters in the long season. Mean litter size was 4.56 (2-6). Ovarian follicles were largest in September and smallest in May. Small, inactive CL persisted in parous females until May. Placental scars were present in all sampled months. Vaginae remained closed during the non-breeding season. In mature males testes and epididymides contained sperm from July to March. Vesicular, prostate and preputial glands were enlarged and secretory from September to December. Testes were smallest and least developed in May and June. Males were divided into five categories depending on age and overall reproductive condition. Sexual maturity was reached in the breeding season of birth by some males (33%) and females (13-88%). More females matured early when population density was low. Food abundance and quality may have been important variables in regulating the timing of the breeding season.
