    Rowe, Melissah; Skerget, Sheri; Rosenow, Matthew A; Karr, Timothy L (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Spermatozoa exhibit remarkable variability in size, shape, and performance. Our understanding of the molecular basis of this variation, however, is limited, especially in avian taxa. The zebra finch (Taeniopygia guttata) ...
  • Innate and adaptive immune proteins in the preen gland secretions of male house sparrows 
    Carneiro, Diana; Czirják, Gábor Árpád; Rowe, Melissah (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Recent studies have demonstrated that preen oil acts to reduce or eliminate feather‐associated bacteria. The mechanisms underlying this antibacterial activity, however, are incompletely understood. In addition to the ...
  • Measuring sperm swimming performance in birds: effects of dilution, suspension medium, mechanical agitation, and sperm number 
    Cramer, Emily Rebecca A; Rowe, Melissah; Eroukhmanoff, Fabrice; Lifjeld, Jan Terje; Sætre, Glenn-Peter; Johnsen, Arild (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Sperm swimming performance, including swimming speed and the proportion of motile cells, may strongly affect fertilization success. However, little is known about how methodological factors affect in vitro measurement of ...
  • Molecular diversification of the seminal fluid proteome in a recently diverged passerine species pair 
    Rowe, Melissah; Whittington, Emma; Borziak, Kirill; Ravinet, Mark; Eroukhmanoff, Fabrice; Sætre, Glenn-Peter; Dorus, Steve (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Seminal fluid proteins (SFPs) mediate an array of postmating reproductive processes that influence fertilization and fertility. As such, it is widely held that SFPs may contribute to postmating, prezygotic reproductive ...
  • Positive correlations between pre- and post-copulatory sexual traits in warblers 
    Supriya, K.; Price, Trevor; Rowe, Melissah (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Theoretical models predict that investment in pre-copulatory and post-copulatory sexually selected traits should trade-off. At the macroevolutionary scale, the majority of studies to date have focused on male weaponry as ...
  • Reproductive coordination breeds success: the importance of the partnership in avian sperm biology 
    Hurley, Laura; Rowe, Melissah; Griffith, Simon (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    Previous experience with a partner can improve reproductive coordination between a pair and increase offspring production. We paired inexperienced zebra finches and investigated how a pairs’ experience and their reproductive ...
  • Resource variation generates positive correlations between pre- and postcopulatory sexual traits 
    Supriya, K.; Price, Trevor; Rowe, Melissah (Journal article / Tidsskriftartikkel / SubmittedVersion; Peer reviewed, 2018)
    Male fertilization success depends on investment in both pre- and postcopulatory sexually selected traits, and considerable attention has recently been paid to quantifying the strength and direction of covariance between ...

    Støstad, Hanna Nyborg; Rowe, Melissah; Johnsen, Arild; Tomasek, Oldrich; Albrecht, Tomas; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    In a rapidly changing world, it is important to understand how urban environments impact wildlife. For example, supplementary feeding of birds, though well‐intended, might have unexpected negative effects on the health of ...
