Vertical canopy gradients in δ13C correspond with leaf nitrogen content in a mixed-species conifer forest
Stable carbon isotope composition varies markedly between sun and shade leaves, with sun leaves being invariably more enriched (i.e., they contain more13C). Several hypotheses have emerged to explain this pattern...

Altitude trends in conifer leaf morphology and stable carbon isotope composition
The natural ratio of stable carbon isotopes (δ13C) was compared to leaf structural and chemical characteristics in evergreen conifers in the north-central Rockies, United States. We sought a general model that wo...

Alström syndrome: further evidence for linkage to human chromosome 2p13
Alström syndrome is a rare autosomal recessive disorder characterized by retinal degeneration, sensorineural hearing loss, early-onset obesity, and non-insulin-dependent diabetes mellitus. The gene for Alströ...

How Important Are Organic Acids in Generating Secondary Porosity in the Subsurface?
The hypothesis that organic acids are responsible for the creation of significant volumes of secondary porosity and the enhancement of aluminium mobility in the subsurface is reviewed against data from reservo...

Genetic Studies on Eµ-myc Transgenic Mice
Transgenic mice carrying the c-myc oncogene under the control of the Ig heavy chain enhancer (“Eµ-myc” mice)(Cory and Adams, 1988; Harris et al., 1988a) develop B lineage tumors within the first year of life, and...

Drought and shade interact to cause fine-root mortality in Douglas-fir seedlings
Both desiccation and depleted carbohydrate reserves have been suggested as causes of fine-root (≤2 mm in diameter) mortality in trees. In this study, Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings w...
