The status of Agardhiella tenera and Agardhiella baileyi (Rhodophyta, Gigartinales)
(Kluwer Academic Publishers; Dr. W. Junk B.V. Publishers ; Springer Science+Business Media, 1973-10)
Evidence is presented to support the placement of Agardhiella tenera in Solieria (as S. tenera comb. nov.) for the reason that a large fusion cell is present in the center of the cystocarp. Since A. tenera is the type ...
Partial characterization of dinoflagellate chromosomal proteins
(Elsevier, 1974-05-31)
Dinoflagellate chromosomal proteins were analyzed by acrylamide gel electrophoresis. The electrophoretic pattern of acid-insoluble chromosomal proteins from Gyrodinium cohnii in sodium dodecylsulfate gels is less heterogeneous ...
The presence of protease activity in the rectal fluid of attine ants
(Elsevier, 1970-02)
The rectal fluid of twenty-two species of ants, including seven species of Attini, seven species of non-attine Myrmicinae, and eight species of Formicinae was assayed for proteolytic enzyme activity. Significant activity ...
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 ...
Patterns of tooth size variability in the dentition of primates
(Wiley Subscription Services, Inc., A Wiley Company, 1979-09)
Published data on tooth size in 48 species of non-human primates have been analyzed to determine patterns of variability in the primate dentition. Average coefficients of variation calculated for all species, with males ...
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, ...
The primary vascular system of Callixylon
(Elsevier, 1979-08)
The primary vascular system of Callixylon (main stem axes of Archaeopteris) is composed of a discontinous cylinder of longitudinal bundles from some of which traces diverge radially in a regular, helical pattern. Tangential ...
