Character 28 was ordered based upon ontogenetic data, and all remaining characters were left unordered.
In the case of migratory species, habitat switch can be sometimes imperative in order to reach a particular ontogenetic stage.
In order to determine if there were ontogenetic shifts in movement, we needed an estimate of shark size when they left the Puget Sound region.
Ontogenetic allometric trajectories and developmental simulations were employed in order to identify growth patterns and to visualize potential adult shapes of ATD6-69.
Thus, in order to understand phylogenetic relationships, one must understand ontogenetic relationships (Hall 1996).
In order to estimate the spatial scale of the ontogenetic migration phenomenon, a field survey of the whole shelf is inevitable.
By definition, these movements traverse salinity gradients at some life history stage, theoretically in order to continually maximize growth and survival despite ontogenetic shifts in risks and requirements [1] [2].
In order to incorporate phenotypic variation among traits across different ontogenetic stages, individuals across the entire post-settlement size range of each species were sampled.
From the perspective of developmental studies, the finding of vertically oriented clonally related neurons has inspired the concept of ontogenetic columns, which (in the primate) constitute ensembles of on the order of 10 neurons each (Rakic 1988).
The American Alligator (Alligator mississippiensis) is a model species for studying ecological implications of ontogenetic niche shifts, because they grow in size by several orders of magnitude, and they play a critical role as both top predators and ecosystem engineers.
Most organisms undergo ontogenetic shifts during their development, often resulting in individuals switching habitats in order to exploit superior food resources, shelter and establish or enhance mating opportunities [6].
