  • Dale, Svein; Lifjeld, Jan T; Rowe, Melissah (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Background Several life history and ecological variables have been reported to affect the likelihood of species becoming urbanized. Recently, studies have also focused on the role of brain size in explaining ...
  • Hurley, Laura L; Rowe, Melissah; Griffith, Simon C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Speciation research has largely overlooked reproductive barriers acting between copulation and the formation of the zygote (i.e., postmating, prezygotic [PMPZ] barriers), especially in internally fertilizing vertebrates. ...
  • K, Supriya; Rowe, Melissah; Laskemoen, Terje; Mohan, Dhananjai; Price, Trevor; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / SubmittedVersion, 2016)
    Sperm morphological traits are highly variable among species and are commonly thought to evolve by post-copulatory sexual selection. However, little is known about the evolutionary dynamics of sperm morphology, and whether ...
  • Lifjeld, Jan T; Gohli, Jostein; Albrecht, Tomáš; Garcia-del-Rey, Eduardo; Johannessen, Lars E; Kleven, Oddmund; Marki, Petter Z; Omotoriogun, Taiwo C; Rowe, Melissah; Johnsen, Arild (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Background Female promiscuity is highly variable among birds, and particularly among songbirds. Comparative work has identified several patterns of covariation with social, sexual, ecological and life history ...
  • Eroukhmanoff, Fabrice; Rowe, Melissah; Cramer, Emily R A; Haas, Fredrik; Hermansen, Jo S; Runemark, Anna; Johnsen, Arild; Sætre, Glenn-Peter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Background Postzygotic isolation in the form of reduced viability and/or fertility of hybrids may help maintain species boundaries in the face of interspecific gene flow. Past hybridization events between ...
  • Hurley, Laura L.; McDiarmid, Callum S; Friesen, Christopher R.; Griffith, Simon C.; Rowe, Melissah (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    English
  • 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) ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Støstad, Hanna Nyborg; Rowe, Melissah; Johnsen, Arild; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Sperm morphology varies enormously across the animal kingdom. Whilst knowledge of the factors that drive the evolution of interspecific variation in sperm morphology is accumulating, we currently have little understanding ...
  • Støstad, Hanna Nyborg; Johnsen, Arild; Lifjeld, Jan Terje; Rowe, Melissah (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Sperm exhibit extraordinary levels of morphological diversification across the animal kingdom. In songbirds, sperm have a helically shaped head incorporating a distinct acrosomal membrane or “helical keel,” the form and ...
  • Omotoriogun, Taiwo Crossby; Albrecht, Tomas; Hořak, David; Laskemoen, Terje; Ottosson, Ulf; Rowe, Melissah; Sedlacek, Ondrej; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    Sperm morphology is highly diversified across the animal kingdom and recent comparative evidence from passerine birds suggests that postcopulatory sexual selection is a significant driver of sperm evolution. In the present ...
  • Rowe, Melissah; Griffith, Simon C; Hofgaard, Antje; Lifjeld, Jan T (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Background Evolutionary biology endeavours to explain biological diversity, and as such it is critical to develop an understanding of the adaptive and functional significance of trait variation. Spermatozoa ...
  • Omotoriogun, Taiwo Crossby; Laskemoen, Terje; Rowe, Melissah; Albrecht, Tomáš; Bowie, Rauri C.K.; Sedláček, Ondřej; Hořak, David; Ottosson, Ulf; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    Birds show considerable variation in sperm morphology. Closely related species and subspecies can show diagnostic differences in sperm size. There is also variation in sperm size among males within a population, and recent ...
