Allometric scaling in the dentition of primates and prediction of body weight from tooth size in fossils
(Wiley Subscription Services, Inc., A Wiley Company, 1982-05)
Tooth size varies exponentially with body weight in primates. Logarithmic transformation of tooth crown area and body weight yields a linear model of slope 0.67 as an isometric (geometric) baseline for study of dental ...
Development of a photosynthesis model with an emphasis on ecological applications
(Springer-Verlag, 1980-05)
A physiologically based steady-state model of whole leaf photosynthesis (WHOLEPHOT) is used to describe net photosynthesis daily time courses in Prunus armeniaca . Net photosynthesis rates are calculated in response to ...
The effects of quantity and quality of diet nitrogen on the growth, efficiency of food utilization, nitrogen budget, and metabolic rate of fifth-instar Spodoptera eridania larvae (Lepidoptera: Noctuidae)
(Elsevier, 1989)
Relative growth rate and relative nitrogen accumulation rate for fifth-instar Spodoptera eridania larvae vary less than 20% on artificial diets in which protein content varies more than 250%, due to compensatory adjustments ...
Cytotaxonomy of the Seychelles tree frog, Megalixalus seychellensis (Duméril and Bibron) (Amphibia: Hyperoliidae)
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1980-04)
The Seychelles tree frog, Megalixalus seychellensis has 2n=24 chromosomes of gradually decreasing length. Pairs 2, 3, and 4 are submetacentric, and the remaining pairs are metacentric. The karyotype affirms hyperoliid ...
Comments on the paper by B. M. Hausein et. al: 5,8-dihydroxyflavone (primetin) the contact sensitizer of Primula mistassinica Michaux
(Springer-Verlag; Springer-Verlag GmbH & Co. KG, 1985-01)
Tannin assays in ecological studies Precipitation of ribulose-1,5-bisphosphate carboxylase/oxygenase by tannic acid, quebracho, and oak foliage extracts
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-02)
Tannic acid and quebracho precipitate many times their weight of the abundant leaf protein, ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPC). The use of this protein in protein precipitation assays for tannin content ...
Techniques for preparation of pyrite and limonite permineralizations
(Elsevier, 1982-02)
Procedures are presented for the preparation of fine-polished surfaces of pyrite permineralizations, and demineralized thin-sections of limonite permineralizations. A major new feature in both procedures involves the ...
Characterization of a mutant polyoma that expresses in F9 embryonal carcinoma cells: Morphology, tumorigenicity, and restriction enzyme analysis
(Elsevier, 1987-08)
A mutant polyoma virus (TT340), which replicates in F9 embryonal carcinoma (EC) cells and contains 2500 base pairs (bp) of additional DNA located in the early noncoding region of the genome, was analyzed to determine the ...
The diurnal time course of net photosynthesis of soybean leaves: Analysis with a physiologically based steady-state photosynthesis model
(Springer-Verlag, 1980-09)
A physiologically based steady-state model of whole leaf photosynthesis (WHOLEPHOT) is used to analyze observed net photosynthesis daily time courses of soybean, Glycine max (L.) Merr., leaves. Observations during two time ...
