The Distribution of Arsenic in the Body Tissues of Wood Mice and Bank Voles
Arsenic is accumulated by free-living small mammals, but there is little information on the resultant concentrations in different tissues other than liver and kidney. Such information is important because the ...

Does copper tolerance give cadmium tolerance in Mimulus guttatus
Copper tolerance in Mimulus guttatus Fischer ex DC, is controlled by a single major gene, plus a number of minor genes (or modifiers) which elevate copper tolerance. Homozygous copper tolerant and nontolerant lin...

Nickel tolerance and copper - nickel co - tolerance in Mimulus guttatus from copper mine and serpentine habitats
Previous work on M. guttatus suggested that nickel tolerance in copper mine populations may also be given by the genes for copper tolerance. It has been shown that copper tolerance in M. guttatus is controlled...

Biomass allocation, phosphorus nutrition and vesicular-arbuscular mycorrhizal infection in clones of Yorkshire Fog, Holcus lanatus L. (Poaceae) that differ in their phosphate uptake kinetics and tolerance to arsenate
Biomass and phosphorus allocation were determined in arsenate tolerant and non-tolerant clones of the grass Holcus lanatus L. in both solution culture and in soil. Arsenate is a phosphate analogue and is taken up...

Genetics of arsenic tolerance in Agrostis capillaris L.
The genetic control of arsenic tolerance in Agrostis capillaris is examined by two experiments, one involving natural seed families collected from the wild and one based on the six basic generations from a cross ...

Why the evolution of resistance to anthropogenic toxins normally involves major gene changes: the limits to natural selection
Standard population genetic theory suggests that adaptation should normally be achieved by the spread of many genes each of small effect (polygenes), and that adaptation by major genes should be unusual. Such ...

Reproductive isolation as a pleiotropic effect of copper tolerance in Mimulus guttatus?
A genetic system producing postmating reproductive isolation between two populations of Mimulus guttatus is described. In one population, Copperopolis, there is a single gene tightly linked to, or pleiotropic to,...

The genetic control of copper tolerance in the yellow monkey flower, Mimulus guttatus
Evidence is presented that copper tolerance in the yellow monkey flower, Mimulus guttatus is determined primarily by a single major gene. Selfed progenies of segregating T × T families produce families which are ...

The number of genes on the second chromosome of Drosophila melanogaster and a comment on the genetic structure of eukaryotes
Recessive lethals on the second chromosome were extracted from genetically isolated populations in Australia and the U.K. The frequency of allelism, used in a manner analogous to capture-recapture of animal po...

Major genes for copper tolerance in Mimulus guttatus
HEAVY metal tolerance in higher plants has proved to be an excellent model system which has provided insight into several aspects of the evolutionary process (see ref. 1 for review). But comparatively little i...
