Development of a photosynthesis model with an emphasis on ecological applications
(Springer-Verlag, 1976-06)
In this paper, a description of photosynthesis in a single leaf is developed that separates physiological sub-processes and that is practical to apply as an ecological tool. Temperature dependencies are emphasized with the ...
Genetic variation in the carbonic anhydrase isozymes of macaque monkeys. I. The radioimmunosorbent assay
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-02)
A radioimmunosorbent technique is described which is capable of independently detecting both isozymes of carbonic anhydrase, CA I and CA II, in concentrations as low as 1 ng/ml. The technique is used to quantitate the ...
Innervation of free muscle grafts in the rat in the absence of mechanical trauma to surrounding muscles or nerves
(Elsevier, 1976-09-01)
Soleus muscles in the rat were freely grafted alongside a normal soleus muscle in the absence of mechanical trauma to any of the surrounding muscles or motor nerves. The object of this experiment was to determine whether ...
Kynurenine metabolism in rats: Some hormonal factors affecting enzyme activities
(Elsevier, 1975-07-15)
The effects of certain long-term hormonal treatments of male and female rats on the activities of several enzymes involved in kynurenine synthesis and degradation were determined to further rationalize previously observed ...
Chemical characterization of a new Japanese variant of carbonic anhydrase I, CA I Nagasaki 1 (76 Arg→Gln)
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1979-06)
A new inherited variant of carbonic anhydrase I (CA I), designated CA I Nagasaki 1 (CA I NGS 1 ), was discovered during a survey of hemolysates from 5852 individuals from the cities of Hiroshima and Nagasaki in Japan. ...
Ultraviolet light-induced recombination
(Elsevier, 1973-12-10)
Stimulation of transduction in by ultraviolet irradiation of the transducing phage P1 requires the nuclease but not the product or DNA polymerase I. It is hypothesized that the first step in "normal" recombination can ...
Dispersal of sweet pignut hickory in a year of low fruit production, and the influence of predation by a curculionid beetle
(Springer-Verlag, 1977-09)
The rate at which fallen hickory nuts are removed from beneath the parent tree, and the effect on this rate of the seed predator Conotrachelus affinis , was studied in an oak-hickory forest in southeastern Michigan, USA, ...
L-kynurenine aminotransferase and L-[alpha]-aminoadipate aminotransferase. I. Evidence for identity
(Elsevier, 1975-01-20)
SummaryThe following observations strongly suggest that L-kynurenine aminotransferase (KAT) and L-[alpha]-aminoadipate aminotransferase (AAT) activities are associated with the same protein: 1. a similar distribution in ...
Dual control of lysogeny by bacteriophage P22: An antirepressor locus and its controlling elements
(Elsevier, 1975-02-05)
Two distantly linked clusters of genes on the Salmonella typhimurium phage P22 chromosome are involved in the control of lysogeny and superinfection immunity. One cluster consists of genes c1, c2, and c3, which are primarily ...
Analysis of an acoustic pacemaker in Strecker's chorus frog, Pseudacris streckeri (Anura: Hylidae)
(Springer-Verlag, 1974-03)
1. In breeding assemblages of Pseudacris streckeri the mating call of one individual often occurs immediately after that of another. Calling by one male then becomes entrained to that of another even though their intrinsic ...
