Population limitation and the adaptive value of territorial behaviour in Scottish Red grouse, Lagopus l. scoticus

  • A. Watson


Recent research on Red grouse in Scotland has concentrated on mechanisms which limit populations (Watson and Moss, 1972). This chapter concerns the adaptive value of territorial behaviour in population limitation, an aspect of evolutionary significance largely developed by David Lack, and of lasting interest to him.
