Insects exposed to stress, such as lack of food or exposure to high temperatures, may be more susceptible to the action of pathogens, which is indicated by a change in their life cycle and the development of their ontogenetic
stages (Sikorowski & Lawrence 1994; Rampelotti et al.
finmarchicus shows differential ontogenetic
patterns among major clades of opsin transcripts.
Changes in otolith ring width and distance from the core are expected to occur after the ontogenetic
shift in feeding strategy.
Relative feeding specialization may depress ontogenetic
, seasonal, and sexual variations in diet: the endemic lizard Cnemidophorus littoralis (Teiidae).
The study of ontogenetic
peculiarities and the structure of coenopopulations (CP) allows us to talk about proliferation or suppression of any species in a certain habitat.
Aeglids also have low dispersal potential, missing a larval stage in its ontogenetic
development, and strict environmental requirements such as clear and oxygenated water (Melo, 2003).

development of the digestive tract in reared spotted sand bass Paralabrax maculatofasciatus larvae.
So the ontogenetic
shift observed by Taylor (2001) probably can be explained because lizards were easier to swallow when the rattlesnakes were juveniles and have a reduced gape size.
