  1. Pinus sylvestris L. J.L Keyser 2850186

  2. Also called Scots Pine • Found in Britain, Spain and North America • A coniferous tree that can grow up to 20-40m tall • Life span of 150-300 years • Colour of needles – blue-green • Yellow, pink or violet-red monoecious flower

  3. Only four variations are recognized: • Pinus sylvestris var. sylvestris, Pinussylvestris var. hamata, Pinus sylvestris var. mongolica and Pinus sylverstris var. nevadensis • National tree of Scotland

  4. Burczyk (1995) estimatated effected population size. • Number of individuals that contribute gametes to next generation. • Used the multilocus gametic frequency method. • Only looked at male gametes • Thus only variance in effected population size contributed by males can be estimated

  5. Estimated variance in effective population size of trees showed that gametes contributed by males was the same as the breeding population of the orchard. • Method used useful only for small effective population sizes
