| [biochemical polymorphism of japanese quail (coturnix coturnix japonica): comparison of functionally different proteins (author's transl)]. | the polymorphism observed among the enzymes involved in the respiratory metabolism (lactate dehydrogenase, malate dehydrogenase, phosphoglucomutase, phosphohexoseisomerase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase fructose 1-6 diphosphate dehydrogenase) is less important than that of the enzymes physiologically less essential, such as the various esterases, the alkaline phosphatase, the alcohol dehydrogenase, and of the non-enzymatic proteins (ovalbumin, ovoglobulins, ... | 1975 | 1140313 |
| preference and discrimination between response-dependent and response-independent schedules of reinforcement. | four asian quail (coturnix coturnix japonica) were exposed to concurrent-chain schedules, the terminal links of which were either variable-interval 30 sec and variable-time 30 sec, or fixed-interval 30 sec and fixed-time 30 sec. except for one bird that exhibited a preference for the variable-interval schedule over the variable-time schedule, no consistent preferences were demonstrated for response-dependent or response-independent schedules. however, response rates were three times greater on r ... | 1975 | 16811865 |

| binary assessment of early approach-behaviour in the japanese quail. | visually-elicited early approach-behaviour was studied in 1013 japanese quail chicks (coturnix coturnix japonica) by a newly developed, binary assessment procedure. this procedure was shown to be highly effective for identifying approach preferences and related indivisual differences in early approach-behaviour. experimental results show that quail chicks exhibit approach-responses to a flashing light. within various paired intensity-combinations of the tested intensity-range of approximately tw ... | 1975 | 1163852 |
