LIFE HISTORY, BEHAVIOR AND MORPHOLOGY OF THE IMMATURE STAGES OF ENOCHRUS QUADRIPUNCTATUS HERBST IN THE LABORATORY (COLEOPTERA: HYDROPHILIDAE) I- LIFE HISTORY AND BEHAVIOR
The life history of Enochrus quadripunctatus Herbst was studied in the laboratory. The duration of each developmental stage, larval behavior, and preimaginal mortality rate were determined. It takes the insect a total of 43 days from hatching to reach the adult stage, with a high mortality rate in the first stadium. The mortality rate decreases as the beetle passes through the immature sta...

متن کاملFunctional morphology of the heart in fishes.
SYNOPSIS. The systemic heart of fishes consists of four chambers in series, the sinus venosus, atrium, ventricle, and conus or bulbus. Valves between the chambers and contraction of all chambers except the bulbus maintain a unidirectional blood flow through the heart. The heart is composed of typical vertebrate cardiac muscle, although there may be minor differences in the distribution of spont...

15 صفحه اولVisual pigments in the early life stages of Pacific northwest marine fishes.
Microspectrophotometry was used to measure the visual pigments in the rods and cones of 22 species of marine fish larvae netted from the surface waters off Friday Harbor Laboratories, Washington, USA. 13 species had rods, 12 of which contained visual pigments with a wavelength of maximum absorbance near 500 nm, while one, the sand lance (Ammodytes hexapterus), had its absorbance maximum at 482 ...
