“…However, few adolescents and juveniles persisted past the autumn, and the winter minima were usually composed only of adults. A shifting phase analysis correlation (Horton and West 1977) between abundance in one season and that in the corresponding season 12 months later showed no significant seasonal pattern for adult cats, but it did for subadults ( r = 0.70, P < 0.01). …”

This paper reports home range sizes and population ecology of feral cats in a 19000-ha study area situated in the Victorian Mallee. Movements of six cats were monitored by radio-tracking for 8-21 months. Adults maintained discrete home ranges; areas varied from 3 . 3 to 9 . 9 (mean 6.2) km2 for males and from 0 . 7 to 2 . 7 (mean 1 ,7) km2 for females. Rabbit warrens, hollow logs and dense thickets were favoured daytime refuges. Mean daily straight-line distances moved bet-veen daytime refuges varied from 0.06 km for a female with juveniles to 1.67 km for an adult male. Relative abundance of cats over four years showed seasonal fluctuations, with summer maxima and winter or spring minima; the calculated mean summer and winter densities were 2.4 and 0.74 cats per km2 respectively. Summer maxima were composed of adults, adolescents and juveniles; winter minima were usually composed only of adults. Mortality, presumably caused by a nutritional stress acting particularly on subadults, maintained the adult population at a relatively stable level.

“…Each series o f measurements was completed within 5 min and the animals remained un disturbed at all other times apart from the watering period mentioned above. The feed intake data before and after the phase shift in lighting was analysed by the shifting phase analysis correlation technique as described previously (11).…”

Male and female guinea pigs maintained under controlled lighting and fed ad libitum exhibit a diurnal fluctuation in feed intake. This is characterised by periods of increased eating activity at the beginning and end of the light period and in the middle of the dark period. However, the feed consumption for the light and dark periods is similar. If the normal lighting cycle is retarded by 6 h, the guinea pigs adjust their diurnal rhythm of eating to the new cycle within 8 days. Similar findings in female rabbits have previously been reported from this laboratory.
