Daily increments in stem radius were determined from hourly dendrometer measurements in each of three irrigated Eucalyptus nitens and E. globulus trees. Multiple regressions determined from daily weather variables accounted for 40–50% of the variance in increment. The use of weather variables lagged by 1–2 days increased the variance explained. The diurnal(More)
Two field studies in Kenya and an experimental challenge study in the USA were done to assess the accuracy of a dipstick antigen-capture assay based on qualitative detection of Plasmodium falciparum histidine-rich protein 2 (PfHRP-2) in peripheral blood for diagnosis of P falciparum infection. In these studies, the assay was 96.5-100% sensitive for(More)
An experiment was established in two high quality Eucalyptus nitens Deane and Maiden (Maiden) plantations in Tasmania. At the start of the experiment the trees were three years old and the plantations were on the point of canopy closure. Selected trees were pruned to remove 0, 50% or 70% of the lower green crown length, and each was surrounded by eight(More)
 Development of the relationship between leaf area (A l ) and sapwood area (A s ) was investigated in two important hardwoods, Eucalyptus globulus (Labill) and E. nitens (Deane and Maiden) Maiden, growing in an experimental plantation established in a low rainfall zone (approx. 515 mm year–1) of Tasmania. The experiment compared irrigated controls and a(More)
Interference by an introduced grass, Holcus lanatus L. (Yorkshire fog grass) in a young E. globulus (Tasmanian blue gum) plantation was investigated. The objectives were to determine (1) the ‘critical period’ of competition, and (2) how the timing and duration of competition was related to the interaction between tree growth and resource availability. This(More)
 Three-year-old Eucalyptus nitens (Deane and Maiden) Maiden trees and 1-year-old ramets of a single clone of E. nitens were pruned to remove 0, 50% or 70% of the green crown length. This was equivalent to removal of 0, 55% or 88% of foliage area of trees, and 0, 77% or 94% of foliage area of ramets. CO2 assimilation (A) and stomatal conductance (gs) were(More)
The effects of cold-induced photoinhibition on Eucalyptus globulus and Eucalyptus nitens seedlings were assessed between planting and age 23 weeks. The seedlings were subjected to four treatments before planting: non-hardened (NH) E. globulus and E. nitens, cold-hardened (CH) E. nitens, and nutrient-starved (NS) E. nitens. Seedlings were planted alongside(More)
 Green pruning was used to induce source limitation in 1-year-old Eucalyptus nitens (Deane and Maiden) Maiden plants in an investigation of regulation of net CO2 assimilation (A). The pruning regimes involved removal of 0, 50% or 70% of the length of green crown, equivalent to 0, 78% or 95% of leaf area respectively. Gas exchange measurements were made on(More)
Blood-stage level Plasmodium falciparum infection (parasitemia density) is generally elevated prior to, or at the time of, clinical presentation of severe pediatric malaria episodes. Intensity of exposure to infective Anopheles mosquito bites is a suspected determinant of higher density parasitemia. Analyses of entomologic and parasitologic data collected(More)
Malaria has had a major influence on military campaigns for thousands of years. In this paper we summarize the experience of U.S. Navy and Marine forces with malaria during wars of the twentieth century. During World War I, there were 4,746 new cases of malaria, 68,373 sick-days because of malaria, and 7 deaths due to malaria; during World War II, there(More)
