Creator Transcript
  • Their experimental animals have very large spleen, large adrenals + thymus. In commenting on my data [R.A.] Haldane suggested that selection on range peripheries tended to be against non diversity dep. [dependent] factors such as climate + thus permitted increase of range, while under optimum they were against density dep. [dependent] factors + permitted increased density. He suggests that too great mobility might be disadvantageous to a species by continually flooding the peripheral populations + preventing the development of pops. [populations] with new adjustments to climate etc [etcetera]. Alan Robertson impressed me as an excellent type of geneticist for us - about 38-42, good personality, speaks well, good grasp of need of outdoor genetics even with Drosophila. April 9. Yesterday took the children to Peebles to visit the Wm [William] Blackwoods for a week. Today I went up by train to Aberdeen to record a program on wildlife conservation for B.B.C. [British Broadcasting Corporation] The havock [havoc] in the forests along the way is unbelievable. Others on the broadcast were Sir Henry Beresford-Smith director of Forestry for Scotland George Waterston, Colin Murdock + A.M.
