Personality Traits Predict Hierarchy Rank In Male Rainbowfish Social Groups, Mathieu Colléter, Culum Brown
Personality Traits Predict Hierarchy Rank In Male Rainbowfish Social Groups, Mathieu Colléter, Culum Brown
Sentience Collection
Personality traits are becoming increasingly important in explaining adaptive individual differences in animal behaviour and probably represent a leading edge of the evolutionary process. Despite the newfound interest in animal personality among behavioural ecologists, fewstudies have investigated the link between personality traits and fitness measures. We examined this link using male rainbowfish, Melanotaenia duboulayi, as a model species and found that a range of personality traits (aggression, activity and boldness) covaried with a male’s position in a hierarchy, which is directly related to reproductive success in this and many other species. Dominant fish were more aggressive, active, bold and also …
Physiological And Genetic Correlates Of Boldness: Characterising The Mechanisms Of Behavioural Variation In Rainbow Trout, Oncorhynchus Mykiss, Jack S. Thomson, Phillip C. Watts, T. G. Pottinger, Lynne U. Sneddon
Physiological And Genetic Correlates Of Boldness: Characterising The Mechanisms Of Behavioural Variation In Rainbow Trout, Oncorhynchus Mykiss, Jack S. Thomson, Phillip C. Watts, T. G. Pottinger, Lynne U. Sneddon
Ethology Collection
Bold, risk-taking animals have previously been putatively linked with a proactive stress coping style whereas it is suggested shyer, risk-averse animals exhibit a reactive coping style. The aim of this study was to investigate whether differences in the expression of bold-type behaviour were evident within and between two lines of rainbow trout, Oncorhynchus mykiss, selectively bred for a low (LR) or high (HR) endocrine response to stress, and to link boldness and stress responsiveness with the expression of related candidate genes. Boldness was determined in individual fish over two trials by measuring the latency to approach a novel object. Differences …

Human Health Implications Of Intensive Poultry Production And Avian Influenza
Human Health Implications Of Intensive Poultry Production And Avian Influenza
Agribusiness Reports
The high stocking density, stress, unhygienic conditions, lack of sunlight, and breeding practices typical of industrial poultry and egg production systems may facilitate the emergence and spread of diseases, including highly pathogenic avian influenza viruses with public health implications such as H5N1.
