The College Mathematics Journal, 2004
A student research project is an open-ended question or set of questions that is intended to give undergraduate students experience doing "junior" mathematical research. Readers are invited to share especially interesting and fruitful examples of such projects in this section.

Analyzing growth components in trees [PDF]
Journal of Theoretical Biology, 2007 Observed growth, as given, for instance, by the length of successive annual shoots along the main axis of a plant, is mainly the result of two components: an ontogenetic component and an environmental component. An open question is whether the ontogenetic component along an axis at the growth unit or annual shoot scale takes the form of a trend or of a

Extension and Radial Growth in Trees
Nature, 1950IT has already been reported1 that in the broad-leaved trees of India the extension growth or height growth usually precedes the radial growth, and that the gap between these two activities varies from two weeks to three months, irrespective of the fact whether the trees produce ring-porous or diffuse-porous woods. Since 1947, further investigation has

Nature, 2000
Carbon deposition under extreme conditions causes tree-like structures to spring up. The complex deposition and growth of graphitic carbon has come up with several surprises in recent years, including the growth of fullerenes and carbon nanotubes1. Here we describe the spectacular growth of micron-sized tree-like carbon structures produced by chemical ...

Limits to Tree Growth and Longevity
Trends in Plant Science, 2018Tree growth and longevity are key features to understand fundamental issues of plant biology, environmental sciences, and current forest management plans. Here I discuss current evidence on the limits of tree growth and longevity and present a new conceptual framework to understand how and why they are closely interconnected.

Faster tree growth is no panacea
Science, 2017Climate Change Climate warming, nitrogen deposition, and (in fertile ecosystems) elevated carbon dioxide may cause plants to grow faster. Can this growth stimulation lead to higher carbon storage in existing forests and help to mitigate climate change?

BioScience, 1980
The present and projected needs for increased food production in the world are well recognized. Less attention has been directed towards future demands for fiber crops, which may be in more critical shortage than food crops. Trees-the main fiber-producing species-also provide fuel, animal feed, human food, and chemical feedstocks, as well as aesthetic ...
