In designing this research, we are pitting an evolutionary disposition to dislike spiders against a genetic disposition to prefer animals with neotenic
characteristics, in this case jumping spiders (Family Salticidae).
SM[alpha]-actin, the specific biomarkers of VSMC, was used to identify the cell type in neotenic
deppeana, also this taxon shows an evident simplification and reduction in frequency and dimension of the absorbing trichomes passing from the "neotenic
" (young) form to the adult form (Adams e Martin 1986), probably counterbalanced by the growth in dimension of the plant and hence the increased capability to intercept and retain water and solutes inside the rosetta leaves.
" means that the salamander "does not metamorphose into a terrestrial form and retains its bright red external gills throughout life." Id.
There are three known si ghtings in the South Dakota Natural Heritage data base (Backlund, personal communication), but whether these represent the mudpuppy or neotenic
examples of the tiger salamander is uncertain.
However, the action of thyroxine on neotenic
salamander species (i.e., those that do not undergo metamorphosis and reproduce as Killed animals) has varied impacts, ranging from no effect to complete metamorphosis.
The occurrence of neotenic
salamanders, Ambystoma tigrinum diaboli Dunn, in Devil's Lake, North Dakota.
All of this is possible precisely because we are neotenic
evolution of Delphinium nudicaule (Ranunculaceae): a hummingbird-pollinated larkspur.
Moreover, a related Mexican salamander, Ambystoma taylory, which lives in Lake Alchichica near Orizaba, has both neotenic
and metamorphosed forms.
The life cycle of female mealybugs consists of an egg, often laid inside a filamentous ovisac, 3 nymphal stages, and a wingless neotenic
adult stage (Franco et al.
The leaf rachis in climbing Desmoncus (11 of the 12 species)is prolonged into a cirrus, except in Desmoncus stans, which is a small, slightly creeping, often erect palm, interpreted as a neotenic
