Alvar Palmgren (28 April 1880 – 30 November 1960) was a

ecologist
.

Palmgren studied botany at the University of Helsinki under professor J.P. Norrlin. He graduated (Fil.kand.) in 1906 and obtained his Ph.D. in 1914. He became docent of botany at the University of Helsinki 1916 and professor of botany at the same university in 1928 (from 1938, the first in the special Swedish-language chair of botany). He retired in 1950.[1]

Research

Palmgren worked as a

Henry Gleason on the individualistic behaviour of species in community assembly already from the 1920s.[2]
Palmgren wrote early accounts on the role of isolation and stochastic events in the distribution of species, while his contemporary biology was largely deterministic.[3][4][5]

Jaccard dispute

In the 1920s, Palmgren entered in a heated dispute with the

C. B. Williams and again reiterated by Peter Grant and Daniel Simberloff
in the 1970s.

Miscellaneous

Palmgren was on the board of Societas pro Fauna et Flora Fennica from 1916. He was chairman 1920–1957.

In addition to his botanical work, Palmgren made an impressive political act as a 22-year-old student. He initiated and led a movement among young Finnish men to refuse

Nicholas II of Russia, sovereign of the Grand Duchy of Finland, put Finnish conscripts under the Russian
military top. The 'strike' movement forced a withdrawal by 1905.

Alvar Palmgren was the father of the zoologist Pontus Palmgren (1907–1993).
