Sperry, John S. | Anatomy of the palm Rhapis excelsa, VIII. Vessel network and vessel-length distribution in the stem | THE CONCEPT of the vessel, a conducting unit consisting of a series of vessel elements lined up end to end, has been known for well over a century (e.g., Hartig, 1878). The fact that vessels are of limited length is of considerable functional importance. If a vessel is damaged (for example, by an in... | Palm stems; Palm stem anatomy; Vessel network; Vessel-length distribution; Primary vascular stem tissue; Hydraulic architechture; Water column | 1982 |

Sperry, John S. | Observations of reaction fibers in leaves of dicotyledons | HALLE, OLDEMAN, AND TOMLINSON (1978) have discussed the transference of function between compound leaves and plagiotropic branches in the context of tree architecture. In trees conforming to Cook's model (see Halle, Oldeman, & Tomlinson, 1978), plagiotropic branches resemble compound leaves in their... | Reaction fibers; Compound leaves | 1982 |

Olivera, Baldomero M. | Poly (ADP-ribosylation) in Vitro: reaction parameters and enzyme mechanism | The reaction catalyzed by poly(ADP-ribose) synthetase from bovine thymus was investigated using the purified enzyme, calf thymus DNA, and histone H1. The rate and extent of poly(ADP-ribosylation), as well as the spectrum of acceptor proteins, changed as reaction conditions were varied. The ionic co... | ADP-ribosylation; Poly(ADP-ribose) synthetase; Histone H1 | 1982 |

Coley, Phyllis D. | Rates of herbivory on different tropical trees | Rates of herbivory on marked young and mature leaves from saplings of 21 canopy tree species were measured in the wet and dry seasons. Species were classified into two life history groups: persistent species which are found throughout the shaded understory, and pioneer species which only become e... | Herbivory; Grazing damage; Tropical trees; Pioneer species; Trees -- Tropics | 1982 |
