Divergence in the functional morphology and feeding kinematics of threespine stickleback
Meeting Abstract 32.6 Thursday, Jan. 5 Divergence in the functional morphology and feeding kinematics of threespine stickleback MCGEE, M.D.*; WAINWRIGHT, P.C.; Univ. of California, Davis; Univ. of California, Davis mcgee.matthew@gmail.com Studies of adaptive radiation rarely examine divergence across functional systems. We examined functional morphological divergence between benthic and limnetic threespine stickleback from British Columbia. We measured eleven […]
