The cerebellar anatomy of red junglefowl and white leghorn chickens: insights into the effects of domestication on the cerebellum by Kelsey J. Racicot, Christina Popic, Felipe Cunha, Dominic Wright, Rie Henriksen, Andrew N. Iwaniuk

“…In contrast with this general pattern, the chicken has a larger cerebellum compared with the wild red junglefowl, but what neuroanatomical changes are responsible for this difference have yet to be investigated. …”

Activity, social and sexual behaviour in Red Junglefowl selected for divergent levels of fear of humans. by Rebecca Katajamaa, Lovisa H Larsson, Paulina Lundberg, Ida Sörensen, Per Jensen

“…It has therefore been suggested that tameness may drive the domesticated phenotype as correlated traits. We selected Red Junglefowl for divergent levels of fear of human for eight generations and assessed possible correlated selection responses in other behaviours in semi-natural settings. …”

Increased dietary 5-hydroxytryptophan reduces fearfulness in red junglefowl hens (Gallus gallus) by Kristoffer Anton Lundgren, Hanne Løvlie

“…We here aimed to experimentally manipulate the serotonergic system in red junglefowl hens (Gallus gallus), the main ancestor of all domesticated chickens. …”

Selection for reduced fear in red junglefowl changes brain composition and affects fear memory by Rebecca Katajamaa, Per Jensen

“…This reduction can happen through changes in individual brain regions as a response to selection on specific behaviours. We selected red junglefowl for 10 generations for diverging levels of fear towards humans and measured brain size and composition as well as habituation learning and conditioned place preference learning in young chicks. …”

Effects of domestication on responses of chickens and red junglefowl to conspecific calls: A pilot study. by Vitor Hugo Bessa Ferreira, Mylène Dutour, Rebecca Oscarsson, Johanna Gjøen, Per Jensen

“…We first compared the behavioral reaction of domesticated White Leghorn (WL, a breed selected for egg production) and Red Junglefowl (RJF) hens (ancestor of domestic chickens). …”

Brain size is reduced by selection for tameness in Red Junglefowl– correlated effects in vital organs by Beatrix Agnvall, Johan Bélteky, Per Jensen

“…We hypothesize that this could be a correlated effect to increased tameness. Red Junglefowl (ancestors of domestic chickens) were selected for divergent levels of fear of humans for five generations. …”

Sexual selection and personality: individual and group-level effects on mating behaviour in red junglefowl by Roth, AM, Dingemanse, NJ, Nakagawa, S, McDonald, GC, Løvlie, H, Robledo-Ruiz, DA, Pizzari, T

“…</strong> We first examined how two repeatable behaviors — exploration and boldness — are associated with pre- and postcopulatory sexual selection, with a focus on the former, in male red junglefowl, Gallus gallus, using replicate groups across three experimental sex ratio treatments. …”

The ecology of reproductive tract microbiota of a polygynandrous host, the red junglefowl (Gallus gallus) by Veerus, L

“…To fill this gap in knowledge, my thesis investigated the ecology of reproductive tract microbiota of the polygynandrous red junglefowl (Gallus gallus). By using state-of-the-art technologies developed in the field of microbial ecology, I carried out a thorough survey of bacteria associated with reproductive tracts. …”

Exploring the Relationship Between Boldness, Activity, Exploration and Monoaminergic Gene Expression in Red Junglefowl Chicks by Kristoffer A. Lundgren, Clara A. Gómez Dunlop, Laura C. Garnham, Sara Ryding, Robin N. Abbey-Lee, Anastasia Kreshchenko, Hanne Løvlie

“…Therefore, to replicate this general approach and examine if genes from these systems are linked to boldness, activity, and exploration, we exposed red junglefowl chicks (Gallus gallus) to behavioral assays (measuring boldness, activity, exploration) before analyzing prefrontal cortex gene expression of several dopaminergic (DRD1, DRD2) and serotonergic genes (TPH, 5HT2A, 5HT2B, 5HT2C, 5HT1B). …”

Gut Microbiota Linked with Reduced Fear of Humans in Red Junglefowl Has Implications for Early Domestication by Lara C. Puetz, Tom O. Delmont, Ostaizka Aizpurua, Chunxue Guo, Guojie Zhang, Rebecca Katajamaa, Per Jensen, M. Thomas P. Gilbert

“…Here, the gut microbiome community in two selected lines of red junglefowl that are selected for either high or low fear of humans up to eight generations is examined. …”

Pre- and postcopulatory sexual selection favor aggressive, young males in polyandrous groups of red junglefowl by Pizzari, T

“…Here, we combine fine-grained behavioural information (&gt;41,000 interactions) with molecular parentage data to study sexual selection in replicated, age-structured groups of polyandrous red junglefowl, Gallus gallus. Male reproductive success was determined by the number of females mated (precopulatory sexual selection) and his paternity share, which was driven by the polyandry of his female partners (postcopulatory sexual selection). …”

Historic and modern genomes unveil a domestic introgression gradient in a wild red junglefowl population by Meng Yue Wu, Gabriel Weijie Low, Giovanni Forcina, Hein vanGrouw, Benjamin P. Y‐H. Lee, Rachel Rui Ying Oh, Frank E. Rheindt

Comparison of the Chinese bamboo partridge and red Junglefowl genome sequences highlights the importance of demography in genome evolution by G. P. Tiley, R. T. Kimball, E. L. Braun, J. G. Burleigh

“…However, despite the great interest in economically important phasianids like Gallus gallus (Red Junglefowl, the progenitor of the chicken), we know little about the genomes of closely related species. …”

Gene expression of behaviorally relevant genes in the cerebral hemisphere changes after selection for tameness in Red Junglefowl. by Johan Bélteky, Beatrix Agnvall, Per Jensen

“…We conclude that five generations of divergent selection for high or low tameness has significantly changed gene expression patterns in the cerebral hemisphere in the Red Junglefowl population used here, which could underlie a range of changes in the domestic phenotype.…”

Dynamic phenotypic correlates of social status and mating effort in male and female red junglefowl, Gallus gallus by Carleial, R, McDonald, GC, Pizzari, T

“…Here, we test multiple hypotheses addressing this question in replicate flocks of red junglefowl (Gallus gallus). First, we test the interrelationships between social status, comb size (a fleshy ornament) and body mass at the onset of a mating trial. …”
