British ecologist (1935–2021)
John Philip Grime FRS[1] (30 April 1935 – 19 April 2021)[2] was an ecologist and emeritus professor at the University of Sheffield.[3] He is best known for the universal adaptive strategy theory (UAST) and the twin filter model of community assembly with Simon Pierce, eco-evolutionary dynamics, the unimodal relationship between species richness and site productivity ("humped-back model"), the intermediate disturbance hypothesis, and DST classification (dominants, subordinates and transients).[4]
Grime's 1979 book Plant Strategies and Vegetation Processes[5][6] has been cited more than 1,200 times.[citation needed] Together with many influential scientific papers, it has made him a highly cited scientist.[7] In an interview Grime has stated that "Ecology lacks a Periodic Table", quoting Richard Southwood.[4]
Education
Grime obtained his PhD from University of Sheffield in 1960.[3]
Career and research
Grime joined the staff of the department of botany at Sheffield in 1961. He worked at the Connecticut Agricultural Experiment Station, US from 1963 to 1964. He then returned to the University of Sheffield and joined the unit of comparative plant ecology, which had been founded in 1961 by professor Ian H. Rorison.[citation needed] Grime served as deputy director of the unit 1964–1989 and as director from 1989.[citation needed]
Plant strategies
His work and his theories are focused on plant strategies, as developed along their evolutionary history. His CSR theory says that each plant species has a blend of the three strategies that he labels C (competitive), S (stress tolerant) and R (ruderal, or rapid propagation). Ruderal strategists thrive in disturbed areas.[8] He has described a method to classify herbaceous vegetations by analysing the importance of the three strategies in the genotypes of the species that are present.[9]

Awards and honours
In 1991, Grime was inducted as a foreign member of the Royal Netherlands Academy of Arts and Sciences.[14] In 1997, he won the Marsh Ecology Award from the British Ecological Society and was awarded honorary membership of the Ecological Society of America. He was also Distinguished Visiting Ecologist at Pennsylvania State University in that year. In 1998, he was elected Fellow of the Royal Society (FRS)[1] and honorary doctor at University of Nijmegen. He has been honorary member of the British Ecological Society since 1999. He was the first ever recipient of the Alexander von Humboldt Medal (2011) for his outstanding contribution to the intellectual development of plant community ecology.[15]
In 2013, the Journal of Ecology published a collection of Grime's most influential papers, for which he wrote a blog post and recorded an accompanying podcast interview.[1][16]
