Polyphosphate present in DNA preparations from fungal species of Collectotrichum inhibits restriction endonucleases and other enzymes
During the development of a procedure for the isolation of total genomic DNA from filamentous fungi (Rodriguez, R. J., and Yoder, 0. C., Exp. Mycol. 15, 232-242, 1991) a cell fraction was isolated which inhibited the digestion of DNA by restriction enzymes. After elimination of DNA, RNA, proteins, and lipids, the active compound was purified by gel filtration to yield a single fraction capable of

Monitoring of the in-river migration of smolts from two groups of spring chinook salmon, Oncorhynchus tshawytscha (Walbaum), with different profiles of Renibacterium salmoninarum infection
Broodstock segregation based on the measurement of maternal Renibacterium salmoninarum infection levels by the enzyme-linked immunosorbent assay (ELISA) and the membrane filtration-fluorescent antibody technique (MF-FAT) was previously shown to affect the prevalence and levels of bacterial kidney disease (BKD) in progeny of chinook salmon, Oncorhynchus tshawytscha (Walbaum), during hatchery rearin

Probabalistic projections for recovery of the endangered Cui-ui
The cui-ui Chamistes cujus, a lake sucker found in only Pyramid Lake, Nevada, is listed as endangered under the U.S. Endangered Species Act, and a recovery plan has been formulated in an effort to save it. We used a population simulation model that incorporated environmental stochasticity in water availability to project the persistence of cui-ui over 200 years, Based on this approach, recovery of

Differentiation of bacterial feeding nematodes in soil ecological studies by means of arbitrarily primed PCR
Arbitrarily-primed polymerase chain reaction (ap-PCR) was used to differentiate closely related bacterial-feeding nematodes of the genera: Caenorhabditis, Acrobeloides, Cephalobus and Zeldia. Average percentage similarity of bands generated by ap-PCR with seven different primers between 14 isolates of Caenorhabditis elegans was ⪢ 90%, whereas between C. elegans, C. briggsae and C. remanei similari

Predation of juvenile salmonids by smallmouth bass and northern squawfish in the Columbia River near Richland, Washington
The importance of juvenile salmonids in the diet of smallmouth bass Micropterus dolomieu and northern squawfish Ptychocheilus oregonensis was examined at a 6-km stretch of the Columbia River. Piscivorous fish were sampled with electrofishing gear on 4 d (May 2–3 and June 20–21, 1990) during emigration of juvenile anadromous salmonids. Sixty-two smallmouth bass and 69 northern squawfish were collec

Interaction between native and nonnative fish of the upper Muddy River, Nevada
I investigated interactions between native and nonnative fishes in the upper Muddy River system to add insight into (1) the mechanism causing the decline of the Moapa dace Moapa coriacea after the introduction of the shortfin molly Poecilia mexicana, (2) the reason Moapa White River springfish Crenichthys bailevi moapaewere less affected by the introduction, and (3) the reason interactions between

Identification of a whitefly species by genomic and behavioral studies
An introduced whitefly species, responsible for over a half billion dollars in damage to U.S. agricultural production in 1991, is morphologically indistinguishable from Bemisia tabaci (Gennadius). However, with the use of polymerase chain reaction-based DNA differentiation tests, allozymic frequency analyses, crossing experiments, and mating behavior studies, the introduced whitefly is found to be
