Sensitization to stress: The enduring effects of prior stress on amphetamine-induced rotational behavior
(Elsevier, 1985-09-16)
In rats with a unilateral 6-OHDA lesion of the substantia nigra exposure to footshock or immobilization stress produced a long-lasting enhancement in the rotational behavior evoked by a subsequent injection of amphetamine. ...
Energy Content of Young Alewives in Eastern Lake Michigan and Muskegon Lake, a Connected Drowned River Mouth Lake
(Taylor & Francis GroupWiley Periodicals, Inc., 2009-04)
Energy content is an important determinant of an individual fish’s condition and a key input variable for bioenergetics applications. Energy content of young fish can change rapidly during ontogeny; given the numerical ...
Do Brown Trout Choose Locations with Reduced Turbulence?
(Wiley Periodicals, Inc.Taylor & Francis Group, 2006-05)
The physical habitat requirements of cover, depth, and current speed for brown trout Salmo trutta are associated with high shear zones in stream flows, which in turn result in high turbulence. Observations were made on ...
Purification and properties of an oxygen-evolving reaction center complex from photosystem II membranes : A simple procedure utilizing a non-ionic detergent and elevated ionic strength
(Elsevier, 1986-03-03)
A method is reported for the isolation of a highly resolved oxygen-evolving photosystem II reaction center preparation. This preparation can be separated from the more complex photosystem II membranes isolated by the ...
Lead activates calmodulin sensitive processes
(Elsevier, 1983-09-05)
The effect of lead on two calcium sensitive processes was determined. Micromolar concentrations of lead successfully replaced calcium in the activation of calmodulin-sensitive phosphodiesterase and in the promotion of ...
Linkage of the structural gene for uroporphyrinogen I synthase to markers on mouse chromosome 9 in a cross between feral and inbred mice
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1982-08)
The Ups locus has been mapped to mouse chromosome 9 in a three-point cross. The observed gene order is centromere- Ups -15- Mpi-1 -22- Mod-1 . Ups is unlinked to Lv , which encodes the previous enzyme in the heme biosynthesis ...
Mesh size and collection characteristics of 50-cm diameter conical plankton nets
(Kluwer Academic Publishers; Dr. W. Junk Publishers ; Springer Science+Business Media, 1985-03)
This paper compares collection characteristics of #2-(363 µm), #10-(156 µm), and #20-(76 µm) mesh conical plankton nets: dimensions were 50-cm diameter by 1.6-m long. The #2-mesh net severely underestimated the abundances ...
The new approach to wilderness preservation through benefit-cost analysis
(Elsevier, 1982-03)
Over the last 15 years, economists of Resources for the Future led by John Krutilla have been developing a new approach to wilderness preservation. This paper offers a concise exposition of their approach and adds a few ...
Degenerative and regenerative changes in the trochlear nerve of goldfish
(Kluwer Academic Publishers; Chapman and Hall Ltd ; Springer Science+Business Media, 1984-08)
The features of unlesioned and lesioned trochlear nerves of goldfish have been examined electron microscopically. Lesioned nerves were studied between 1 and 107 days after cutting or crushing the nerve. 1. Unlesioned nerves ...
