Age structure and growth of the rough scad, Trachurus lathami (Teleostei: Carangidae), in the Southeastern Brazilian Bight

open access: yesZoologia (Curitiba), 2017
The rough scad, Trachurus lathami Nichols, 1920, is a small pelagic species distributed along the West Atlantic coast. It is most abundant in the Southern Brazil (28°30’-34°S) and in the Southeastern Brazilian Bight (SEBB, 22°-28°30’S). The rough scad is

Toward an Intermediate Structural Representation of Organization in Complex Systems

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Organization is widely recognized as a fundamental concept in complex systems science, yet it rarely appears as an explicit object of scientific representation. Existing approaches successfully represent components, interactions, mechanisms, dynamical states, networks, or functions, but organizational properties are generally inferred from ...

Comparison of Electronic Length Frequency Analysis (ELEFAN) for Estimation of Growth Parameters for Lollyfish, Holothuria (Holothuria) atra and Sand Sea Cucumber, Holothuria (Thymiosycia) arenicola (Holothuroidea: Echinodermata) in the North Arabian Sea, Pakistan

open access: yesMarine Science and Technology Bulletin, 2020
To estimate the growth parameters, the non-seasonal von Bertalanffy and Hoenig seasonal von Bertalanffy models were fitted to the length frequency data of Holothuria atra and H. arenicola obtained from coastal areas of Karachi in the northern Arabian Sea,

A Two-Step Growth Curve: Approach to the von Bertalanffy and Gompertz Equations

open access: yes, 2016
Many curves have been proposed and debated to model individual growth of marine invertebrates. Broadly, they fall into two classes, first order (e.g. von Bertalanffy) and sigmoidal (e.g. Gompertz).

Capturing Networked Knowledge in a Doctoral Research Training Network: First Findings—The MINDSHIFT Case Study

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT MINDSHIFT was an EU‐funded doctoral research‐training network on hypertension involving 15 PhD projects across six universities. We present MINDSHIFT as a case study of how a distributed network may develop, structure, and integrate mechanistic knowledge across diverse projects.

Rising temperature non‐additively alters how different dimensions of biodiversity affect ecosystem‐scale processes

open access: yesJournal of Animal Ecology, EarlyView.
The authors distil how dimensions of biodiversity drive ecosystem processes with increasing temperature. Specifically, species physiology more greatly affected ecosystem primary production than did foraging behaviour, and physiology mediated non‐additive interactions with temperature.

VON BERTALANFFY GROWTH CURVE OF THE RUDD (Scardinius erythrophthalmus L.) FROM THE LAKE KLJUČIĆ BRDO, CENTRAL CROATIA [PDF]

open access: yesCroatian Journal of Fisheries, 2011
The rudd is a cyprinid herbivorous freshwater fish. The samples of rudd have been taken from the „Ključić brdo“ location. The arithmetic mean of length for each age group was determined according to Peterson, Danish ichthyologist.

Weathering the storm: Most maternal and environmental drivers of individual reproductive success do not scale up to population recruitment in a large herbivore

open access: yesJournal of Animal Ecology, EarlyView.
Using 18 years of data on eastern grey kangaroos, we show that drivers of individual reproductive success often do not scale up to population recruitment. Birth asynchrony could buffer population recruitment against environmental variability, such that variables affecting individual reproduction have little impact at the population level.
