Abstract
Summary: In continental populations of Rangifer fertility in females is normally both high and relatively constant. The largest recorded va riation in annual rate of pregnancy within a single population is less than two-fold (range = 57.0-87.0 %, T. ^ Skogland, pers. comm.). In high arctic island populations, by contrast, fertility is highly variable: annual rates of birth in Svalbard reindeer (R. tarandus platyrhynchus), for example, vary up to eight-fold (range = 9.0-73.3 %, Tyler 1987, see also Tho mas 1982). The physiological mechanisms re sponsible for changes in fertility in cervids are not known. However, fertility in females is in fluenced by both body weight and fat reserves (Dauphine 1976, Leader-Williams and Ricketts 1982, Reimers 1983, Thomas 1982) and in red

Summary: In continental populations of Rangifer fertility in females is normally both high and relatively constant
Fertility in females is influenced by both body weight and fat reserves (Dauphine 1976, Leader-Williams and Ricketts 1982, Reimers 1983, Thomas 1982) and in red deer Cervus elaphus these effects have been shown to be independent (Albon et al 1986)
The influence of age and reproductive status on body composition was studied in female Svalbard reindeer shot in late autumn and early winter
