Age, growth and sexual dimorphism of the monkeyface prickleback (Cebidichthys violaceus)

Journal of Fish Biology, EarlyView.
Abstract Accurate estimates of age, growth and maturation are fundamental to fisheries assessment, conservation and the development of emerging aquaculture species. However, life‐history parameters can vary within species and may be influenced by factors such as sexual dimorphism, which is often poorly quantified in non‐commercial or understudied ...

Age and growth of the spiny butterfly ray Gymnura altavela (Elasmobranchii, Gymnuridae) in the Southwest Atlantic (in situ) and under human care in a public aquarium (ex situ): Plasticity and population patterns

Journal of Fish Biology, EarlyView.
Abstract This study provides the first age and growth assessment of the endangered spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the Southwest Atlantic, while also updating the growth parameters (asymptotic disc width—DW∞ and growth coefficient—k) estimated in an ex situ a marine aquarium setting.

Estimating von Bertalanffy parameters with individual and environmental variations in growth

Journal of Biological Dynamics, 2012
Variation among individuals is an ubiquitous feature of natural populations. However, the relative roles of intrinsic individual differences and stochastic processes in generating variation remain poorly understood. For somatic growth, identifying the contribution of individual and stochastic processes to observed variation in size has important ...

Conversational Artificial Intelligence in Everyday Family Life: Conceptualizing Family‐AI Interactions From a Systemic Perspective

Journal of Family Theory &Review, EarlyView.
ABSTRACT Although conversational artificial intelligence (CAI) has become increasingly integrated into daily life, research examining its role is limited to user engagement and Human‐AI interaction. The aim of this article is to review existing research on CAI use in everyday family life and conceptualize its role from a family systemic perspective ...

Synchronization in Von Bertalanffy’s models

, 2013
Many data have been useful to describe the growth of marine mammals, invertebrates and reptiles, seabirds, sea turtles and fishes, using the logistic, the Gom-pertz and von Bertalanffy's growth models. A generalized family of von Bertalanffy's maps, which is proportional to the right hand side of von Bertalanffy's growth equation, is studied and its ...

Fitting of von Bertalanffy growth model: Stochastic differential equation approach

, 2017
In this paper, the well-known von Bertalanffy growth (VBG) model for estimating age-length relationship in fisheries is considered. It is emphasised that nonlinear estimation procedures should be adopted for fitting the von Bertalanffy nonlinear ...

Founder Effects, Density, and Droughts Alter the Demographic Responses in Insular Elephant Populations

Journal of Zoology, EarlyView.
The management of insular elephant populations is being compromised, thereby affecting the natural ecological processes that may regulate their numbers. Here, we illustrate demographic responses in two case studies from South Africa by reflecting on the historical legacy of elephant population establishment and how a lack of dispersal may hinder ...

The metabolic interpretation of the von Bertalanffy growth rate

Ecological Modelling
The von Bertalanffy Growth Rate (vBGR) has a clear physiological interpretation and is proportional to the volume-specific somatic maintenance rate. This links high maintenance to fast growth, as is exploited by the waste-to-hurry strategists, which experience high food availability peaks during short periods.
