Annual and Spatial Variation of the Kelp Forest Fish Assemblage at San Nicolas Island, California Annual and Spatial Variation of the Kelp Forest Fish Assemblage at San Nicolas Island, California
The kelp forest fishes of San Nicolas Island, California were studied from 1981-1986 to examine the causes of among-site and among-year variation in the fish assemblages. Fish counts and seven physical and biological variables were recorded at six sites around the island every spring and fall. Over the study period, a total of 45 fish species from 18 families were recorded, though...

Differentiation of bacterial feeding nematodes in soil ecological studies by means of arbitrarily primed PCR 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...

Interaction between native and nonnative fish of the upper Muddy River, Nevada 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...

Spawning and rearing habitat use by white sturgeons in the Columbia River downstream from McNary Dam Spawning and rearing habitat use by white sturgeons in the Columbia River downstream from McNary Dam
Spawning and rearing habitats used by white sturgeons Acipenser transmontanuswere described from water temperature, depth, and velocity measurements and substrate types present at sites where eggs, larvae, young-of-the-year, and juveniles (ages 1–7) were collected. Spawning and egg incubation occurred in the swiftest water available (mean water column velocity, 0.8–2.8 m/s), which was...

Hormonal control of hepatic glycogen metabolism in food-deprived, continuously swimming coho salmon Oncorhynchus kisutch Hormonal control of hepatic glycogen metabolism in food-deprived, continuously swimming coho salmon Oncorhynchus kisutch
The plasma cortisol concentration and liver cytosolic glucocorticoid receptor activities of continuously swimming, food-deprived coho salmon (Oncorhynchus kisutch) did not differ from those of resting, fed fish. Plasma glucose concentration was significantly higher in the exercising, starved fish, but there were no significant differences in either hepatic glycogen concentration or...

Nonlinear growth dynamics and the origin of fluctuating asymmetry Nonlinear growth dynamics and the origin of fluctuating asymmetry
The nonlinear, complex nature of biosynthesis magnifies the impacts of small, random perturbations on organism growth, leading to distortions in adaptive allometries and, in particular, to fluctuating asymmetry. These distortions can be partly checked by cell-cell and inter-body part feedback during growth and development, though the latter mechanism also may lead to complex patterns in...
