nonparous females and 2- and 3-yr-old males.
Teat wear and relative width of the pubic symphysis were used to identify
nonparous females, and we assumed most
nonparous females were young-of-the-year.
We predicted that by late summer nonparous 2 yr olds would be heavier than parous 2 yr olds.
Parous 2 yr olds in 1988 gained less than half as much mass as nonparous ones during summer (6.2 [+ or -] 1.0 kg vs.
Uteri from
nonparous females were stained with 2% ammonium sulfide to detect cases of full-litter resorption (Narotsky et al.
It has been inferred that other components of the population not seen during the surveys, specifically adult males and
nonparous adult females, occur in more southern waters around Southampton Island in northwestern Hudson Bay (DFO, 1999; Cosens and Blouw, 2003).
IUGR rates among
nonparous and younger (< 25 years) women were much higher (Table 2).
