Geographic variation and systematics of the western Plethodon

Creator:: Brodie, Edmund D.
Abstract:: The western Plethodon include vandykei vandykei, v. idahoensis, larselli, dunni,vehiculum, stormi, elongatus, and an undescribed form referred to as the "unstriped" Plethodon. These salamanders have been placed into three species groups: the Vandykei group, the Vehiculum group, and the Elongatus group. Range maps are provided and geographic variation is discussed...

Experimental hybridization between Rana pretiosa pretiosa Baird and Girard and Rana cascadae Slater

Creator:: Haertel, John David
Abstract:: Experimental crosses between Rana pretiosa pretiosa Baird and Girard and Rana cascadae Slater, resulted in viable hybrids. Reciprocal differences at the time of fertilization are indicated. A high level of success in producing viable hybrids can be obtained if Rana pretiosa pretiosa is the female of the parent species, The...

Developmental cranial osteology of three species of Rana (Anura)

Creator:: Altig, Ronald Gail
Abstract:: Developmental series of Rana pretiosa (110 specimens), R. cascadae (100 specimens) and R. aurora (115 specimens) were bone stained and cleared in glycerin. The growth and developmental patterns of the skull and selected bones were followed from the first appearance of bone through adult stages. The sequential appearance of the...

A comparative study of the chromosomes from five species of the genus Rana

Creator:: Haertel, John David
Abstract:: The karyotypes of five species of ranid frogs were determined from metaphase plates of bone marrow cells. The colchicine, hypotonic- citrate, blaze-dry technique was used to obtain the plates. Morphometric datawere obtained from the karyotypes and compared with other species of the genus Rana. Like most other members of the...

Controlled potential coulometry in non-aqueous solvents--application to the Karl Fisher determination of water and to aromatic nitro compounds in dimethyl-sulfoxide

Creator:: Lindbeck, Melven Raymond
Abstract:: Aromatic Nitro Compounds. The n-values for the reduction of the isomers of nitrophenol and nitrobenzoic acid and for several other nitro compounds are determined in dimethylsulfoxide by controlled potential coulometry. A procedure is given in which one mole of nitro compound may be determined with errors of less than one...

Efficiency of thorium extraction by primary amines as a function of pulse frequency and amplitude in a pulsed sieve-plate column

Creator:: Davis, Bernard Eric, 1937-
Abstract:: The amine extraction process is evaluated for pulse column operation. A 0.1 M solution of Primene JM-T (a commercial mixture of tertiary-alkyl primary amines) in a kerosene-base diluent is the extractant for thorium feed in aqueous acidic sulfate solutions. Equilibrium isotherms at room temperature are presented at aqueous acidities of...
