Fitting the von Bertalanffy growth equation to polar bear age–weight data
KINGSLEY, M. C. S. 1979. Fitting the von Bertalanffy growth equation to polar bear age-weight data. Can. J. Zool. 57: 1020-1025. Heavy sea ice in the Canadian Arctic in the winter of 19731974 reduced seal populations; polar bears, preying principally on seals, consequently lost weight. The nature and degree of this weight loss was investigated by examining the parameters of von Bertalanffy grow...
متن کاملOn the exponent in the Von Bertalanffy growth model
Von Bertalanffy proposed the differential equation m'(t) = p × m(t) a - q × m(t) for the description of the mass growth of animals as a function m(t) of time t. He suggested that the solution using the metabolic scaling exponent a = 2/3 (Von Bertalanffy growth function VBGF) would be universal for vertebrates. Several authors questioned universality, as for certain species other models would p...
متن کاملGrowth rate fitting using the von Bertalanffy model: analysis of natural populations of Drepanotrema spp. snails (Gastropoda: Planorbidae).
The genus Drepanotrema includes six species in Argentina. The life cycle in natural systems of Drepanotrema depressissimum, and D. lucidum has been little studied, except for some casual observations. The aim of this study is to analyze main population trends (age structures, recruitment periods, life span and curves of individual growth) in Paiva pond, Argentina. We explored growth model fitti...
متن کاملfitting growth regression model to the boolean random sets
one of the models that can be used to study the relationship between boolean random sets and explanatory variables is growth regression model which is defined by generalization of boolean model and permitting its grains distribution to be dependent on the values of explanatory variables. this model can be used in the study of behavior of boolean random sets when their coverage regions variation...
متن کاملStochastic von Bertalanffy models, with applications to fish recruitment.
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. Probability density functions for hitting times are evaluated in the context of fish growth and ...
