In 1969, he was elected as a Fellow of the Royal Society of Canada.[1] The Chitty Hypothesis of Population Regulation states that population density is limited by spacing behaviour, which has genetic underpinnings and rapidly responds to natural selection.[2] Because of the controversial nature of this idea at the time, David Lack attempted to veto Chitty's dissertation, though it was eventually accepted because of the intervention of Peter Medawar.[3] References1. ^[https://rsc-src.ca/civicrm/file?reset=1&id=157&eid=730 Obituary] {{Authority control}}{{DEFAULTSORT:Chitty, Dennis}}{{Canada-scientist-stub}}2. ^{{cite journal|last1=Krebs|first1=Charles J.|title=A review of the Chitty Hypothesis of population regulation|journal=Canadian Journal of Zoology|date=1978|volume=56|issue=12|pages=2463–2480|doi=10.1139/z78-335}} 3. ^[https://www.zoology.ubc.ca/~krebs/ecological_rants/?p=1261 Was the Chitty Hypothesis of Population Regulation a ‘Big Idea’ in Ecology and was it successful?] 8 : 1912 births|2010 deaths|Canadian zoologists|Canadian ecologists|Fellows of the Royal Society of Canada|University of British Columbia faculty|University of Toronto alumni|Alumni of the University of Oxford |
