(Springer-Verlag, 1977-09)
A theoretical description of the simultaneous processes of photosynthesis and photorespiration in a single leaf is developed, based on the hypothesis that carbon dioxide and oxygen compete for the active site of ribulose ...
Changes in serum proteins associated with metamorphosis in salamanders of the family ambystomatidae
(Elsevier, 1976)
1. 1. The effect of metamorphosis on the serum proteins of three genera and five species of ambystomatid salamanders was examined by electrophoresis.2. 2. Four of the five species showed a significant increase in the fastest ...

Rectal enzymes of attine ants. [alpha]-Amylase and chitinase
(Elsevier, 1973-07)
The faecal material of seven species of attine ants from the genera Cyphomyrmex, Apterostigma, Myrmicocrypta, Sericomyrmex, and Atta has been shown to contain [alpha]-amylase and chitinase, but only a trace of uricase. ...
Chemical and chemotactic stimulation of feeding behavior in the hermit crab Petrochirus diogenes
(Elsevier, 1971-08-01)
Various concentrations of fish juice were introduced to appendages of freely moving specimens of Petrochirus diogenes. 1. 1. The threshold concentration for chemical elicitation of feeding behavior was over ten times as ...
