Thermoregulation and heterothermy in some of the smaller flying foxes (Megachiroptera) of New Guinea
(Springer-Verlag, 1970-06)
Body temperature, heterothermy, oxygen consumption, heart rate, and evaporative water loss were studied in four species of flying foxes (Megachiroptera), Dobsonia minor, Nyctimene major, Nyctimene albiventer , and Paranyctimene ...
Morphogenic effects of halogenated thymidine analogues on Drosophila . I. Quantitative analysis of lesions induced by 5-bromodeoxyuridine and 5-fluorouracil
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1972-02)
When 5-fluorouracil (FU) is offered simultaneously with 5-bromodeoxyuridine (BUdR) to Drosophila larvae, a variety of bristle modifications and hyperplastic growths are found on the wings of the adult flies. Administration ...
The totipotency and relationship of seta-bearing cells to thallus development in the green alga Coleochaete scutata. A laser microbeam study
(Elsevier, 1974-03)
The relationship of seta-bearing cells of Coleochaete scutata (Chlorophyta Ulotrichales) to normal growth and development of the thallus was investigated using laser microbeam irradiation. When all of the seta-bearing cells ...
Silicification of developing internodes in the perennial scouring rush (Equisetum hyemale var. affine)
(Elsevier, 1973-03)
An electron microprobe (EMP) analysis of silica (SiO2) deposition in the epidermis of developing internodes of the perennial scouring rush (Equisetum hyemale var. affine) indicates that SiO2 is first detected in the stomatal ...
Nucleotide sequence divergence among DNA fractions of different syngens of Tetrahymena pyriformis
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-09)
The magnitude of the differences in base sequence of DNA fractions derived from different syngens of the ciliated protozoan Tetrahymena pyriformis was investigated. Each DNA was fractionated into unique and repeated sequences ...
