Offspring sex ratio adjustment in reindeer, Rangifer tarandus / I. Kojola, T. Helle.

Title: Offspring sex ratio adjustment in reindeer, Rangifer tarandus / I. Kojola, T. Helle.
Author(s): Kojola, I.
Helle, T.
Date: 1994.
In: Annales Zoologici Fennici. (1994.), Vol. 31(4) (1994)
Abstract: Theoretically parents should be able to improve their fitness by adjusting offspring sex ratio. Do polygynous mothers in superior condition produce more males than weaker females? Rangifer tarandus is one of most polygynous large mammals. Authors did not find any differences in body size, fat reserves or age between semi-domesticated reindeer (R.t.tarandus) females carrying male or female foetuses. One hypothetical reason for lack of affirmative answer is variability in winter foraging conditions that may weaken link between parental investment and offspring sex ratio.
