- Seasonal changes in brain GnRH immunoreactivity and song-control nuclei volumes in an opportunistically breeding songbirdS A MacDougall-Shackleton
Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ, USA
Brain Behav Evol 58:38-48. 2001..However, song control nuclei are dramatically affected by photoperiod. Future work should examine these systems in crossbills breeding on short days to compare photoperiod-dependent and -independent effects on neural plasticity...
- Cultural and genetic evolution in mountain white-crowned sparrows: song dialects are associated with population structureE A MacDougall-Shackleton
Department of Ecology and Evolutionary Biology, Princeton University, New Jersey 08544 1003, USA
Evolution 55:2568-75. 2001..Thus, song dialects appear to be associated with reductions in, but not strict barriers to, gene flow among dialect regions...
