  • This book owes its inception to my fascination with the natural microcosms that are water-filled tree holes and, subsequently, the broader class of plant container habitats we call phytotelmata. That fascination was born, first, in a Somerset woodland, when my fellow undergraduate Alastair Sommerville pointed out to me a massive stump hole, commenting that such places were both entomologically special and of great potential as objects of ecological study.

  • The internode of solid bamboo has significantly higher ash, 1% NaOH, alcohol- toluene and hot water solubles than the nodes [Mabilangan et al. 2002]. However, differences between the major chemical composition of node and internode fraction of bamboo are small [Scurlock 2000]; neither the number of nodes nor the length of internode segments would be critical to the utilization of bamboo for energy conversion, chemical production, or as a building material. Fujji et al. [1993] investigated the chemistry of the immature culm of a moso- bamboo (Phyllostachys pubescens Mazel).

  • There are several differences between bamboo and wood. In bamboo, there are no rays or knots, which give bamboo a far more evenly distributed stresses throughout its length. Bamboo is a hollow tube, sometimes with thin walls, and consequently it is more difficult to join bamboo than pieces of wood. Bamboo does not contain the same chemical extractives as wood, and can therefore be glued very well [Jassen 1995].
