    Cranial ontogeny in Stegoceras validum (Dinosauria: Pachycephalosauria): a quantitative model of pachycephalosaur dome growth and variation. by Ryan K Schott, David C Evans, Mark B Goodwin, John R Horner, Caleb Marshall Brown, Nicholas R Longrich

    Published 2011-01-01
    “…Flat-headed juveniles possess three characters (externally open cranial sutures, tuberculate dorsal surface texture, and open supratemporal fenestrae) that are reduced or eliminated during ontogeny. These characters also occur in putative flat-headed taxa, suggesting that they may also represent juveniles of domed taxa. …”

    Ontogeny of metabolic rate and red blood cell size in eyelid geckos: species follow different paths. by Zuzana Starostová, Marek Konarzewski, Jan Kozłowski, Lukáš Kratochvíl

    Published 2013-01-01
    “…We found support for that prediction in five species of eyelid geckos (family Eublepharidae) with different patterns of RBC size variation during ontogenetic growth. During ontogeny, metabolic rate increases nearly linearly with body mass in those species of eyelid geckos where there is no correlation between RBC size and body mass, whereas non-linearity of metabolic rate scaling is evident in those species with ontogenetic increase of RBC size. …”

    A morphometric approach to conch ontogeny of <i>Cymaclymenia</i> and related genera (Ammonoidea, Late Devonian) by C. Klein, D. Korn

    Published 2014-02-01
    “…Representatives of the Late Devonian ammonoid family Cymaclymeniidae were studied for their conch ontogeny. Two methods were applied: (1) the analysis of classical morphometric conch parameters and (2) an outline analysis of the aperture using elliptic Fourier analysis. …”

    Different time patterns of the presence of red-eared slider influence the ontogeny dynamics of common frog tadpoles by M. Vodrážková, I. Šetlíková, J. Navrátil, M. Berec

    Published 2022-05-01
    “…In this study, we examine the dynamics of the ontogeny of common frog (Rana temporaria) tadpoles under different time patterns of an alien predator—the red-eared slider (Trachemys scripta elegans) presence. …”

    Ontogeny of long-range vocalizations in a Neotropical fossorial rodent: the Anillaco Tuco-Tuco (Ctenomys sp.) by Juan Pablo Amaya, Juan Ignacio Areta

    Published 2018-02-01
    “…The LRV of the Anillaco Tuco-Tuco exhibited a mixed developmental mode: while series developed from juvenile precursors whose acoustic features gradually approached those of adults, individual notes appeared later in the ontogeny and de novo with acoustic features indistinguishable from those of adults. …”

    An Immature Pachyrhinosaurus perotorum (Dinosauria: Ceratopsidae) Nasal Reveals Unexpected Complexity of Craniofacial Ontogeny and Integument in Pachyrhinosaurus. by Anthony R Fiorillo, Ronald S Tykoski

    Published 2013-01-01
    “…The combination of morphologies in the new specimen suggests either an additional stage of development should be recognized in the ontogeny of the nasal boss of Pachyrhinosaurus, or that the ontogenetic pathway of nasal boss development in P. perotorum was notably different from that of P. lakustai. …”

    Delayed phenotypic expression of growth hormone transgenesis during early ontogeny in Atlantic salmon (Salmo salar)? by Darek T R Moreau, A Kurt Gamperl, Garth L Fletcher, Ian A Fleming

    Published 2014-01-01
    “…This study compared the developmental rate and respiratory metabolism of GH transgenic and non-transgenic full sibling Atlantic salmon during early ontogeny; a life history period of intense selection that may provide critical insight into the fitness consequences of escaped transgenics. …”
