Phytoplankton Successions And Lake Dynamics In Las Vegas Bay, Lake Mead, Nevada, Ervon R. Koening, Richard W. Tew, James E. Deacon

Publications (WR)

Phytoplankton successions, applications of the general growth equation, and physical measurements have been employed to investigate events occurring at the interface between industrial and sewage effluent contained in Las Vegas Wash and the waters of Lake Mead, Nevada. The data indicate that the entering waters tend to form a density current interrupted at intervals by dynamic effects generated in the lake. The dynamic relationships described here for the spring months suggest that a much more thorough understanding of physical, chemical and biological interactions is necessary to permit solution of the numerous problems of Las Vegas Bay discussed or alluded to …

A Survey On The Incidence Of Salmonella In The Rio Grande And Irrigation Canals In Albuquerque, Claudio Antonio Dominguez

Biology ETDs

A nine months survey of fecal coliforms, fecal streptococcus, and salmonellae was made in the Rio Grande and adjacent canals. The survey was limited to the Albuquerque area from the Old Town Bridge on Central Ave. to the northern boundary of the Isleta Indian Reservation, south of the Rio Bravo Bridge. My study shows that the fecal coliforms and fecal streptococcus counts follow a seasonal pattern, being low in winter, increasing during spring, and reaching a peak in the summer. Salmonella enteritidis of several serotypes, Oranienburg, Derby, Give, Montevideo, Thomasville, Typhimurium, and Senftenberg, was isolated on nine different occasions. All …

Forty-three species of fleas were collected in Venezuela by personnel of the Smithsonian Venezuelan Project. Currently there are fifty-two species of fleas known from Venezuela. Four new taxa are described: Hormopsylla cryptica, Ctenidiosomus perplexus, Adoratopsylla antiquorum rara and Adoratopsylla antiquorum recta. The females of Adoratopsylla antiquorum discreta Jordan and Rothschildopsylla noctilionis (Costa Lima) are described.

Mites Of The Family Laelapidae In Venezuela (Acarina: Laelapidae), Deane P. Furman

Brigham Young University Science Bulletin, Biological Series

This publication presents the results of an extensive survey of symbiotic laelapid mites of vertebrates from Venezuela. Over 40,000 vertebrates were examined from a wide variety of life zones and localities. The laelapid fauna represented includes 1 new genus, Hymenolaelpas, and 7 genera previously described: Laelaps, Mysolaelaps, Tur, Steptolaelaps, Neoparalaelaps, Gigantolaelaps, and Androlaelaps. The genera are represented by 51 species and subspecies, of which 8 are described as new. Previously unknown males and immatures of several species are described. Gigantolaelaps versteegi ( Oudemans ) is redescribed from type material; G. wolffsohni (Oudemans) is redescribed from Oudemans’ original material; G. peruviana …

Special Report On Hunting

Special Reports

The Humane Society contends that the use of amateur hunters to reduce an overabundant deer herd does not conform with the principles of sound wildlife management. The Humane Society is strongly opposed to any method of culling herds of deer that does not deliver an instant and reasonably merciful death.
