Estimation of growth parameters for the exploited sea cucumber Holothuria arguinensis from South Portugal [PDF]

open access: yes, 2018
Understanding how species grow is critical for choosing appropriate fisheries management strategies. Sea cucumbers shrink during periods of aestivation and have naturally flaccid bodies that make measuring growth difficult.

Optimal and near-optimal exponent-pairs for the Bertalanffy-Pütter growth model [PDF]

open access: yesPeerJ, 2018
The Bertalanffy–Pütter growth model describes mass m at age t by means of the differential equation dm/dt = p * ma − q * mb. The special case using the von Bertalanffy exponent-pair a = 2/3 and b = 1 is most common (it corresponds to the von Bertalanffy ...

Age and growth of Zapteryx brevirostris (Elasmobranchii: Rhinobatidae) in southern Brazil [PDF]

open access: yes, 2018
Age and growth studies are fundamental to successful fisheries management. Zapteryx brevirostris (Muller & Henle, 1841) is distributed off the Brazilian continental shelf and this species is assessed as "Vulnerable" in the Red List of the International ...

Non-Linear Model to Describe Growth Curves of Commercial Turkey in the Tropics of Mexico

open access: yesBrazilian Journal of Poultry Science
The objective of this study was to select the best non-linear model that fits the growth curve of turkeys managed under the tropical conditions of Southern Mexico. Data from 481 Hybrid converter turkeys (236 females and 245 males) reared under commercial

Trade-offs between accuracy and interpretability in von Bertalanffy random-effects models of growth.

open access: yesEcological Applications, 2016
Better understanding of variation in growth will always be an important problem in ecology. Individual variation in growth can arise from a variety of processes; for example, individuals within a population vary in their intrinsic metabolic rates and ...

Age and growth of spiny dogfish (Squalus acanthias) in the Gulf of Alaska: analysis of alternative growth models [PDF]

open access: yes, 2010
Ten growth models were fitted to age and growth data for spiny dogfish (Squalus acanthias) in the Gulf of Alaska. Previous studies of spiny dogfish growth have all fitted the t0 formulation of the von Bertalanffy model without examination of alternative

Evolution of size-dependent flowering in Onopordum illyricum: A quantitative assessment of the role of stochastic selection pressures [PDF]

open access: yes, 1999
We explore the evolution of delayed, size-dependent reproduction in the monocarpic perennial Onopordum illyricum, using a range of mathematical models, parameterized with long-term field data.
