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 mammals of Warren Woods, Berrien County, Michigan

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 ...
Mating strategies in two species of dart-poison frogs: a comparative study
(Elsevier, 1992-06)
Comparative field studies of species of dart-poison frogs in the genus Dendrobates were carried out to test predictions from two hypotheses that attempt to explain female-female competition for mates in species of Dendrobates ...
Evaporative Water Losses of Some Small Australian Lizards
(Ecological Society of AmericaWiley Periodicals, Inc., 1966-06)
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 ...
Sticky molecules in not-so-sticky cells
(Elsevier, 1991)
The assignment of specific roles to cell-surface proteins by standard methods can be a major problem. In the technique described below, Schneider-2 (S2) cells, an established Drosophila cell line, have been used in cell ...
Biosynthesis of alkyl-ether containing lipid from dihydroxyacetone phosphate
(Elsevier, 1969-10-22)
A lipid, stable to alkaline methanolysis, is formed when liver mitochondria or brain microsomes are incubated with dihydroxyacetone phosphate, long chain alcohol, ATP, CoA, NaF and Mg++. The lipid has been identified as ...
