A possible explanation for the differences in diet are ontogenetic
changes in foraging behavior and swimming ability that, in turn, increase foraging areas and feeding opportunities for larger fishes (Graham et al.
There are few species whose fifth instar is described, and fewer to whose complete larval ontogenetic
development is known.
Current proteomic data support the idea that neurotoxic effects observed after developmental DE-71 exposure could arise from the disruption of the normal ontogenetic
pattern of nervous system growth and development through perturbation of intracellular signaling pathways, causing oxidative stress and disrupting energy homeostasis.
With increased predator size influencing prey size selection (intraspecific size selection), and the potential to subdue and drill more profitable prey species (interspecific prey selection), one might expect to find strong evidence of ontogenetic
changes in prey selection in a given naticid species.
pathways to color pattern class B in a newly discovered population of parthenogenetic Aspidoscelis neotesselata (Squamata: Teiidae).
For the purpose of quantitative ontogenetic
analysis we measured four basic morphological characters (Fig.
bifolia was carried out on the basis of all ontogenetic
groups mapping within the test area boundaries of 100-200 [m.
The majority of ontogenetic
shape change in Aplodinotus grunniens (RW1) involves deepening of the body and repositioning of the mouth, such that it is more anteriorly directed (less sub-terminal) in large-bodied fish (Fig.
Many workers recognize that early ontogenetic
specimens of Idiognathodus have morphologic features of another genus, Streptognathodus (for example, Van den Boogaard and Bless, 1985: Sweet, 1988).
factors affecting diffusion dispersal in the introduced Mediterranean gecko, Hemidactylus turcicus.
habitat shifts are particularly common in marine organisms and are widespread among a variety of vertebrates (Price and Grant, 1984; Fishelson et al.
The team were able to pinpoint the phenomenon by working with a technology called ontogenetic
, where nerve cells are rendered photo-sensitive so their action can be turned on or off by different wavelengths of light.
