Molecular transformation, gene cloning, and gene expression systems for filamentous fungi Molecular transformation, gene cloning, and gene expression systems for filamentous fungi
This chapter discusses the molecular transformation, gene cloning, and gene expression systems for filamentous fungi. Molecular transformation involves the movement of discrete amounts of DNA into cells, the expression of genes on the transported DNA, and the sustainable replication of the transforming DNA. The ability to transform fungi is dependent on the stable replication and...

Dam breaching and Chinook salmon recovery Dam breaching and Chinook salmon recovery
The Report by Kareiva et al. on recovery and management options for spring/summer chinook salmon (1) has the potential to have a major impact in deciding whether to breach dams on the Snake River. Based on interpretation of their model results, they argue that dam breaching would be insufficient to reverse the decline of salmon. An examination of the specifics of their model, however...

Length changes in white sturgeon larvae preserved in ethanol or formaldehyde Length changes in white sturgeon larvae preserved in ethanol or formaldehyde
We examined the effects of two preservatives on the notochord and total lengths of white sturgeon (Acipenser transmontanus) larvae. White sturgeon larvae that were one, seven, and 14 days old were measured live and then preserved in 95% ethanol or 10% formaldehyde. Length changes were then determined at 20 and 95 days after preservation. We found mean length changes ranging from 0.4% to...

Mucous lysozyme levels in hatchery coho salmon (Oncorhynchus kisutch) and spring chinook salmon (O. tshawytscha) early in the parr-smolt transformation Mucous lysozyme levels in hatchery coho salmon (Oncorhynchus kisutch) and spring chinook salmon (O. tshawytscha) early in the parr-smolt transformation
Mucous lysozyme concentrations were determined in juvenile coho salmon (Oncorhynchus kisutch) and spring chinook salmon (O. tshawytscha) to establish reference levels during the time associated with the parr-smolt transformation. The first reported naris and vent mucous lysozyme levels are provided for spring chinook salmon and coho salmon. Naris mucous lysozyme levels ranged between 300...

Influence of breeding habitat on bear predation and age at maturity and sexual dimorphism of sockeye salmon populations Influence of breeding habitat on bear predation and age at maturity and sexual dimorphism of sockeye salmon populations
Age structure and morphology differ among Pacific salmon (Oncorhynchus spp.) populations. Sexual selection and reproductive capacity (fecundity and egg size) generally favor large (old), deep-bodied fish. We hypothesized that natural selection from physical access to spawning grounds and size-biased predation by bears, Ursus spp., opposes such large, deep-bodied salmon. Accordingly, size...

Buoyancy compensation of juvenile chinook salmon implanted with two different size dummy transmitters Buoyancy compensation of juvenile chinook salmon implanted with two different size dummy transmitters
We investigated the effect of two different sizes of surgically implanted transmitters on the buoyancy compensation of juvenile chinook salmon Oncorhynchus tshawytscha. We determined buoyancy by measuring the density of fish with a filled air bladder in graded salinity baths. In addition, we examined the effect of pressure changes on buoyancy by measuring the pressure reduction (PR) at...

Green fluorescent protein is lighting up fungal biology Green fluorescent protein is lighting up fungal biology
Prasher (42) cloned a cDNA for the green fluorescent protein (GFP) gene from the jellyfishAequorea victoria in 1992. Shortly thereafter, to the amazement of many investigators, this gene or derivatives thereof were successfully expressed and conferred fluorescence to bacteria andCaenorhabditis elegans cells in culture (10,31), followed by yeast (24, 39), mammals (40), Drosophila (66)...
