Choosing category size in a stage projection matrix
(Springer-Verlag, 1978-01)
A basic problem associated with choosing category size in a stage projection matrix is described. “Errors of estimation” are large if the category size is chosen too small and “errors of distribution” are large if the ...
Non-visual functions of crustacean eyestalk ganglia
(Springer-Verlag, 1971-03)
Ablation experiments demonstrated that in several crustacean groups, the proximal eyestalk ganglia are important in a variety of behavior patterns: 1. Chemical elicitation of feeding via the antennules is altered in lobsters, ...
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 ...
Protein synthesizing systems from spores and vegetative cells of Bacillus cereus
(Springer-Verlag, 1979-06)
A system of polyphenylalanine synthesis was optimized for a comparison of the polymerizing activities of ribosomes from spores and vegetative cells of Bacillus cereus T. Ribosomes of both types react similarly, showing a ...
Development of a photosynthesis model with an emphasis on ecological applications
(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 ...
Development of a photosynthesis model with an emphasis on ecological applications
(Springer-Verlag, 1976-06)
Photosynthesis was measured in leaves of Phaseolus vulgaris and analyzed according to the set of equations outlined previously by Tenhunen et al. (1976).
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 ...
On the regional stabilization of locally unstable predator-prey relationships
(Elsevier, 1973-09-14)
The stabilizing effects of interhabitat migration and local population extinction are established by an analysis of the variable Pi, where Pi refers to the proportion of habitats occupied by species i. This is followed by ...
