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, ...
An idealized concept of the true cladistic character
(Elsevier, 1975-04)
Estimating evolutionary relationships is basic to the objectives of systematics. Comparative data, structured as taxonomic characters, are usually the essential considerations on which such estimates are founded. Some ...
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 ...
The alkanes of the ant, Atta colombica
(Elsevier, 1970)
Two homologous series of trimethylalkanes, the 3,7,11-trimethylalkanes (C34H7), C36H74 and C38H78) and the 4,8,12-trimethylalkanes (C35H72, C37H76 and C39H80) are the major constituents of the cuticular alkanes of the ant, ...
