Ludwig von Bertalanffy's early system approach

Systems Research and Behavioral Science, 2009
AbstractMost of what Bertalanffy published in the field of ‘organismic’ biology was written in German and is thus not widely known. In order to understand the development and meaning of his ‘general system theory’, those early works are essential. In this paper, I therefore focus on key aspects of his ‘system theory of life’, both on the level of ...

Ludwig von Bertalanffy

2009
Ludwig von Bertalanffy was the creator of general systems theory (GST) – he coined the term, developed it in detail in his many writings, and was a key part of the group which took it forward and spread the concept. Indeed, the systems movement would not have taken the form it did without Bertalanffy – for while holistic thinking has arisen in many ...

Stochastic von Bertalanffy models, with applications to fish recruitment

Journal of Theoretical Biology, 2007
We consider three individual-based models describing growth in stochastic environments. Stochastic differential equations (SDEs) with identical von Bertalanffy deterministic parts are formulated, with a stochastic term which decreases, remains constant, or increases with organism size, respectively.

A forgotten message? von Bertalanffy's puzzle

Kybernetes, 2006
PurposeThis paper aims to celebrate Felix Geyer's many contributions to the systems movement. He participated from the beginning, with the energy that has become his hallmark. The area of systems studies was introduced in The Netherlands in about 1970, mainly through the activities of the Systeemgroep Nederland or Dutch Systems Group, initiated by Ab ...

Minor extension of the von Bertalanffy growth theory

Fisheries Research, 1990
The growth of “Growing Sealife”™ plastic squid was tested against the principles of the von Bertalanffy growth theory. The von Bertalanffy growth curve fits the data well on visual inspection, although the Schnute curve actually provides a statistically superior fit.

Flexible von Bertalanffy growth models incorporating Bayesian splines

Ecological Modelling, 2017
Understanding the growth rates of fish is vital for effective fisheries management. Historically a three-parameter von Bertalanffy growth model (VBGM) has most often been used to describe the somatic growth of fish. However, increasingly, populations are identified with patterns of growth that are not adequately described by the standard VBGM.
