Ramensky was a proponent of the view that biotic communities consist of species behaving individualistically (much like Henry Gleason

Selected scientific works

  • Translated to German and published 1930 as Zur Methodik der vergleichenden Bearbeitung und Ordnung von Pflanzenlisten und anderen Objekten, die durch mehrere verschiedenartig wirkende Faktoren bestimmt warden in: Emil Abderhalden
    Emil Abderhalden
    Emil Abderhalden was a Swiss biochemist and physiologist. His main findings, though disputed already in the 1920s, were not finally rejected until the late 1990s. Whether his misleading findings were based on fraud or simply the result of a lack of scientific rigor remains unclear...

    's Beiträge zur Biologie der Pflanzen (Breslau) 18: 269-304.

In this work, Ramensky criticized the use of hierarchical classifications of plant communities and advocated ordination ("Ordnung") of communities (and other complex objects with multiple determining factors, such as soil profile and weather data) instead. He was explicit about assuming unimodal responses of species to underlying gradients in the environment. This was long before Correspondence analysis
Correspondence analysis
Correspondence analysis is a multivariate statistical technique proposed by Hirschfeld and later developed by Jean-Paul Benzécri. It is conceptually similar to principal component analysis, but applies to categorical rather than continuous data...

European Russia refers to the western areas of Russia that lie within Europe, comprising roughly 3,960,000 square kilometres , larger in area than India, and spanning across 40% of Europe. Its eastern border is defined by the Ural Mountains and in the south it is defined by the border with...
