Carbohydrates in Glycine max (L.) Merr. fruits during early ontogeny
The occurrence of starch and other soluble carbohydrates in the embryos and young developing fruits of 'Essex' soybeans were determined at anthesis and continuing 10 days after flowering (DAF). The embryo was shown to be filled with starch grains which disappeared with development. Digestion of …

Assemblage structure and shallow-water habitat use by small-bodied fishes at lower Missouri River sandbars
… important source of SWH to fishes during early ontogeny within the main channel of LMOR. Small-bodied fishes were sampled using pre-positioned electrofishing devices from 0.0-0.5 m water depths adjacent to four point and four wing-dike sandbars on LMOR between July and October, 2005. A …

Immanuel Kant's Sparrow
… of the parents, (3) food availability during early ontogeny, (4) social factors, (5) neuronal mechanisms, (6) hormonal states, and (7) body size and morphology of the vocal tract. House sparrows singing canary-like songs provide a rich tool for further integrative approaches. I suggest an …

Effects of temperature and density on the facial malformation of hatchery-reared cisco, Coregonus artedi
… by preflexion, and possibly earlier, during early ontogeny and the beginning of endochondral ossification. The malformation is characterized by an improperly formed vomer and ethmoid bone. Early onset of the malformation suggests physical trauma is not the sole causative factor, and supports …

IMPORTANCE OF THE D2 RECEPTOR FOR ONE- AND MULTI-TRIAL PSYCHOSTIMULANT-INDUCED BEHAVIORAL SENSITIZATION IN PREWEANLING RATS
… and multi-trial behavioral sensitization during early ontogeny are poorly understood. The purpose of this thesis was to assess the importance of D2-like receptors for the induction of cocaine- and methamphetamine-induced one-trial and multi-trial behavioral sensitization during the middle and …

Foraging of juvenile crappies in turbidity: the difference is black and white
… like turbidity can fluctuate rapidly during the early life of fishes and can impact foraging behaviors, and thus growth and survival. Black (Pomoxis nigromaculatus) and white (P. annularis) crappies have been hypothesized to respond strongly and distinctly to changes in turbidity, with black …

Giraffa camelopardalis: limb bone histology through ontogeny
… specifically on osteohistological changes during ontogeny. The current study investigates the microanatomy and histology of giraffe limb bones through ontogeny. Mid-diaphyseal sections of humeri, radii, metacarpals, femora, and tibiae of 14 individuals representing individuals of known sex, as …
