Estimates of growth and comparisons of growth rates determined from length- and age-based models for populations of purple wrasse (Notolabrus fucicola) [PDF]
, 2005 Growth of a temperate reefa-ssociated fish, the purple wrasse (Notolabrus fucicola), was examined from two sites on the east coast of Tasmania by using age- and length-based models.

System as a Unifying Process: An Onto‐Epistemic Notion of System
Systems Research and Behavioral Science, EarlyView.ABSTRACT This article proposes an onto‐epistemic notion of system as a relational process of unifying a multiplicity of actuals and abstractions into an actual unity, thereby encompassing concreteness and abstraction onto the same plane. This notion rejects the opposition between constructivism and realism within systems studies, the excessive focus on

Zoologia (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

Journal 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.

The Wonder Years: A Demographic Approach to Revisit the Age‐at‐Size Conundrum in Amphibians
Integrative Zoology, EarlyView.We combined repeated body size measurements of marked individuals of unknown age throughout their adult life with growth records of individuals marked as postmetamorphic juveniles and recaptured years later as sexually mature adults, focusing on 10 amphibian species in central Spain.

A note on the von Bertalanffy growth function concerning the allocation of surplus energy to reproduction [PDF]
, 2012 We propose an extended form of the von Bertalanffy growth function (VBGF), where the allocation of surplus energy to reproduction is considered. Any function can be used in our model to describe the ratio of energy allocation for reproduction to that ...

Growth and Variation in Fallow Deer (Dama dama L.) From Two Contrasting Habitats in Southern Britain
Acta Zoologica, EarlyView.ABSTRACT We have compiled a unique data set on the age, sex, body weight and dimensions of over 500 European fallow deer from two contrasting areas of habitat in southern England: a high‐density managed parkland population and a lower‐density feral woodland one.
