Laterality Enhances Numerical Skills In The Guppy, Poecilia Reticulata, Marco Dadda, Christian Agrillo, Angelo Bisazza, Culum Brown Oct 2015

Laterality Enhances Numerical Skills In The Guppy, Poecilia Reticulata, Marco Dadda, Christian Agrillo, Angelo Bisazza, Culum Brown

Sentience Collection

It has been hypothesized that cerebral lateralization can significantly enhance cognition and that this was one of the primary selective forces shaping its wide-spread evolution amongst vertebrate taxa. Here, we tested this hypothesis by examining the link between cerebral lateralization and numerical discrimination. Guppies, Poecilia reticulata, were sorted into left, right and non-lateralized groups using a standard mirror test and their numerical discrimination abilities tested in both natural shoal choice and abstract contexts. Our results show that strongly lateralized guppies have enhanced numerical abilities compared to non-lateralized guppies irrespective of context. These data provide further credence to the notion that …

Valuable Behavioural Phenotypes In Australian Farm Dogs, P. D. Mcgreevy, C. M. Wade, E. R. Arnott, J. B. Early

Livestock and Working Dogs Collection

This report presents findings regarding the ways to optimise the performance of livestock working dogs in Australia. The methods available to optimise dog performance include both environmental and genetic factors. The objectives of this study were to identify objective measures of desirable behavioural phenotypes in Australian livestock working dogs and explore genetic parameters of these 'quality of working life' traits within the Kelpie breed. The document reports on genotyping that reveals gene-behaviour associations and describes heritability estimates that underpin a database for potential estimated breeding value (EBV) calculations.


The Flaws And Human Harms Of Animal Experimentation, Aysha Akhtar Oct 2015

The Flaws And Human Harms Of Animal Experimentation, Aysha Akhtar

Experimentation Collection

Nonhuman animal (“animal”) experimentation is typically defended by arguments that it is reliable, that animals provide sufficiently good models of human biology and diseases to yield relevant information, and that, consequently, its use provides major human health benefits. I demonstrate that a growing body of scientific literature critically assessing the validity of animal experimentation generally (and animal modeling specifically) raises important concerns about its reliability and predictive value for human outcomes and for understanding human physiology. The unreliability of animal experimentation across a wide range of areas undermines scientific arguments in favor of the practice. Additionally, I show how animal …

Social Learning: Parents May Not Always Know Best, Simon C. Griffith, Culum Brown

Social Cognition Collection

The efficiency with which animals learn new skills depends on their ability to choose good tutors. A new study shows that early-life stress causes young zebra finches to switch tutor preference from parents to unrelated adults.
