Journal of Fish Biology, EarlyView.Abstract Black Carp Mylopharyngodon piceus are native to most major east Asian drainages and are internationally cultured for use as a food‐fish or a biological control for molluscs. We describe the reproductive biology of Black Carp from the growing invasive population in the Mississippi River basin through examination of incidental commercial ...

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.

The Gompertz Inverse Exponential (GoIE) distribution with applications [PDF]
, 2018 The Gompertz inverse exponential (GoIE) distribution using the Gompertz generalized family of distributions was derived and introduced in this article. Some basic statistical properties of the model were derived and discussed in minute details.

Statistical Inference on Simple Step-Stress Accelerated Life Testing for Gompertz Distribution Under .Progressive Type-II Censoring [PDF]
Maǧallaẗ Al-Buḥūṯ Al-TiǧāriyyaẗWe consider a simple step-stress model under the Gompertz distribution (GD) when the available data are type-II progressive censored. The cumulative exposure model is assumed when the lifetime of test units follows a Gompertz distribution.

On the Construction of Some Fractional Stochastic Gompertz Models
Mathematics, 2020 The aim of this paper is the construction of stochastic versions for some fractional Gompertz curves. To do this, we first study a class of linear fractional-integral stochastic equations, proving existence and uniqueness of a Gaussian solution.

Journal of Phycology, EarlyView.Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate new hypotheses for the interpretation of metagenomic data and enrich ...

On Hyperbolic Gompertz Growth Model
, 2015 We proposed a Hyperbolic Gompertz Growth Model (HGGM), which was developed by introducing a shape parameter (allometric). This was achieved by convoluting hyperbolic sine function on the intrinsic rate of growth in the classical gompertz growth equation.
