Gene Regulatory Evolution During Speciation in a Songbird
Davidson, John H.; Balakrishnan, Christopher N. (2016-03-10)Over the last decade, tremendous progress has been made toward a comparative un- derstanding of gene regulatory evolution. However, we know little about how gene regulation evolves in birds, and how divergent genomes ... -
High major histocompatibility complex class I polymorphism despite bottlenecks in wild and domesticated populations of the zebra finch (Taeniopygia guttata)
Newhouse, Daniel J.; Balakrishnan, Christopher N. (2015-12)Background: Two subspecies of zebra finch, Taeniopygia guttata castanotis and T. g. guttata are native to Australia and the Lesser Sunda Islands, respectively. The Australian subspecies has been domesticated and is now ... -
Susceptibility and Antibody Response of the Laboratory Model Zebra Finch (Taeniopygia guttata) to West Nile Virus
Hofmeister, Erik K.; Lund, Melissa; Shearn-Bochsler, Valerie; Balakrishnan, Christopher N. (2017-01-03)Since the introduction of West Nile virus (WNV) into North America in 1999 a number of pas- serine bird species have been found to play a role in the amplification of the virus. Arbovirus surveillance, observational studies ... -
Transcriptional response to West Nile virus infection in the zebra finch (Taeniopygia guttata)
Newhouse, Daniel J.; Hofmeister, Erik K.; Balakrishnan, Christopher N. (2017-06)West Nile virus (WNV) is a widespread arbovirus that imposes a significant cost to both human and wildlife health. WNV exists in a bird-mosquito transmission cycle in which passerine birds act as the primary reservoir host. ... -
Understanding the Loss of Maternal Care in Avian Brood Parasites Using Preoptic Area Transcriptome Comparisons in Brood Parasitic and Non-parasitic Blackbirds
Lynch, Kathleen S.; O’Connell, Lauren A.; Louder, Matthew I. M.; Balakrishnan, Christopher N.; Fischer, Eva K. (2019-02-13)Parental care is critical for offspring survival in many species. However, parental behaviors have been lost in roughly 1% of avian species known as the obligate brood parasites. To shed light on molecular and neurobiological ... -
The variability of song variability in zebra finch (Taeniopygia guttata) populations
Lansverk, Allison L.; Schroeder, Katie M.; London, Sarah E.; Griffith, Simon C.; Clayton, David F.; Balakrishnan, Christopher N. (2019-05-15)Birdsong is a classic example of a learned social behaviour. Song behaviour is also influenced by genetic factors, and understanding the relative contributions of genetic and environmental influences remains a major goal. ...
