ontogeny

(ŏn-tŏj′ə-nē)
n. pl. ontoge·nies
The development of an individual organism or a part of an organism from inception to maturity. Also called ontogenesis.

ontogeny

The biological history of the development and growth of a single individual or organism. See Phylogeny.

As discussed by Kitajima & Poorter (2008) the competitive advantage of one species over another along the light gradient is affected by stochastic factors (gaps, mechanical damage) and trade-offs allowing plants to exploit different levels of the light resource at the seedling stage (and throughout ontogeny in general).
macdonaldi of indirect ontogeny at the time of hatching and the first days of life lack a functional stomach, so their intestinal tracts develop in a progressive manner (ZamboninoInfante & Cahu 2001).
Since no information exists on the skeletal ontogeny and anomalies of crimson snappers, the descriptions of skeletal development would minimize this knowledge gap.
We used the Pacific whiteleg shrimp as the model to investigate the transcript changes that lead to proteinase activity in the digestive system during ontogeny. Because of the implications and critical importance of digestive proteolytic enzymes during development, an integrated approach is necessary to describe how changes in transcripts and proteolytic activity participate in digestive physiology during the several larval stages.

However, taking into account the strong development of the rostrum detected in the postnatal ontogeny of P blainvillei skull (Del Castillo et al., 2014) a paedomorphic condition of this species is unlikely.
Great Basin exemplifies a morphotype wherein pygidia expanded rapidly during ontogeny. We document its expansion using Z-stacking microscopy, a technology that facilitates both volumetric measurements and qualitative comparisons.
