    • Complex evolutionary trajectories of sex chromosomes across bird taxa. 

      Zhou, Qi; Zhang, Jilin; Bachtrog, Doris; An, Na; Huang, Quanfei; Jarvis, Erich D; Gilbert, M Thomas P; ... (8 authors) (Science, 2014-12-12)
      Sex-specific chromosomes, like the W of most female birds and the Y of male mammals, usually have lost most genes owing to a lack of recombination. We analyze newly available genomes of 17 bird species representing the avian ...
    • Core and region-enriched networks of behaviorally regulated genes and the singing genome. 

      Whitney, Osceola; Pfenning, Andreas R; Howard, Jason T; Blatti, Charles A; Liu, Fang; Ward, James M; Wang, Rui; ... (14 authors) (Science, 2014-12-12)
      Songbirds represent an important model organism for elucidating molecular mechanisms that link genes with complex behaviors, in part because they have discrete vocal learning circuits that have parallels with those that ...
    • Dopamine receptors in a songbird brain. 

      Kubikova, Lubica; Wada, Kazuhiro; Jarvis, Erich D (J Comp Neurol, 2010-03-15)
      Dopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior. In songbirds, dopamine is released into the striatal song ...
    • Dynamic evolution of the alpha (α) and beta (β) keratins has accompanied integument diversification and the adaptation of birds into novel lifestyles. 

      Greenwold, Matthew J; Bao, Weier; Jarvis, Erich D; Hu, Haofu; Li, Cai; Gilbert, M Thomas P; Zhang, Guojie; ... (8 authors) (BMC Evol Biol, 2014-12-12)
      BACKGROUND: Vertebrate skin appendages are constructed of keratins produced by multigene families. Alpha (α) keratins are found in all vertebrates, while beta (β) keratins are found exclusively in reptiles and birds. We ...
    • Genomic signatures of near-extinction and rebirth of the crested ibis and other endangered bird species. 

      Carey, HV; Chang, L; Chen, C; Chen, T; Cheng, C; Gilbert, M Thomas P; Guo, Y; ... (33 authors) (Genome Biol, 2014)
      BACKGROUND: Nearly one-quarter of all avian species is either threatened or nearly threatened. Of these, 73 species are currently being rescued from going extinct in wildlife sanctuaries. One of the previously most ...
    • Rudimentary substrates for vocal learning in a suboscine. 

      Liu, Wan-chun; Wada, Kazuhiro; Jarvis, Erich D; Nottebohm, Fernando (Nat Commun, 2013)
      Vocal learning has evolved in only a few groups of mammals and birds. The key neuroanatomical and behavioural links bridging vocal learners and non-learners are still unknown. Here we show that a non-vocal-learning suboscine, ...
    • The dusp1 immediate early gene is regulated by natural stimuli predominantly in sensory input neurons. 

      Horita, Haruhito; Wada, Kazuhiro; Rivas, Miriam V; Hara, Erina; Jarvis, Erich D (J Comp Neurol, 2010-07-15)
      Many immediate early genes (IEGs) have activity-dependent induction in a subset of brain subdivisions or neuron types. However, none have been reported yet with regulation specific to thalamic-recipient sensory neurons of ...
    • Whole-genome analyses resolve early branches in the tree of life of modern birds. 

      Jarvis, Erich D; Mirarab, Siavash; Aberer, Andre J; Li, Bo; Houde, Peter; Li, Cai; Ho, Simon YW; ... (106 authors) (Science, 2014-12-12)
      To better determine the history of modern birds, we performed a genome-scale phylogenetic analysis of 48 species representing all orders of Neoaves using phylogenomic methods created to handle genome-scale data. We recovered ...
