Professor Herbert George Andrewartha, BS (UWA), MAgSc (Melb), DSc (Adel), FAA, (21 December 1907 – 27 January 1992) was a distinguished Australian research scientist in the fields of entomology, biology, zoology and animal ecology.
[3] Andrewartha became the most influential Australian ecologist, best known for attributing density-independent forces, such as weather, to be even more important than density-dependent factors in influencing population regulation.
[4] After several years of statistical analysis of that data, Andrewartha and Birch demonstrated strong connections between thrips physiology, population levels, and other environment factors.
[4][5] Through this work, Andrewartha and Birch found a new school of population ecology, which emphasized the role of environmental controls as opposed to a community-dependent approach based on density-dependent factors.
The HG Andrewartha Medal of the Royal Society of South Australia,[8] was established to recognise outstanding research by an early-career, young Australian scientist.
