Abstract
Established forests currently function as a major carbon sink, sequestering as woody biomass about 26% of global fossil fuel emissions. Whether forests continue to act as a global sink will depend on many factors, including the response of aboveground wood production (AWP; MgC ha(-1 ) yr(-1) ) to climate change. Here, we explore how AWP in New Zealand's natural forests is likely to change. We start by statistically modelling the present-day growth of 97 199 individual trees within 1070 permanently marked inventory plots as a function of tree size, competitive neighbourhood and climate. We then use these growth models to identify the factors that most influence present-day AWP and to predict responses to medium-term climate change under different assumptions. We find that if the composition and structure of New Zealand's forests were to remain unchanged over the next 30 years, then AWP would increase by 6-23%, primarily as a result of physiological responses to warmer temperatures (with no appreciable effect of changing rainfall). However, if warmth-requiring trees were able to migrate into currently cooler areas and if denser canopies were able to form, then a different AWP response is likely: forests growing in the cool mountain environments would show a 30% increase in AWP, while those in the lowland would hardly respond (on average, -3% when mean annual temperature exceeds 8.0 °C). We conclude that response of wood production to anthropogenic climate change is not only dependent on the physiological responses of individual trees, but is highly contingent on whether forests adjust in composition and structure.

Abstract
We have been focusing on potential metabolic derangement associated with severe head injury and a clinical trail directed toward treating brain tissue acidosis is currently underway. More specifically, we based this study on the hypothesis that following brain trauma brain tissue acidosis develops which may contribute to the prolongation of coma and neurologic deficit. Tromethamine (THAM), a safe and low toxicity agent which buffers in major part by causing a hypocapnic alkalosis, was selected for trial. Patients admitted with GCS < 8 were randomized into one of three arms: control: THAM plus hyperventilation; hyperventilation alone. Each regimen was maintained for 5 days post injury. Our analysis of 3 and 6 months Glasgow outcome score showed that prophylactic hyperventilation retards recovery, and the use of THAM overcomes the apparent deleterious effects of hyperventilation. One explanation is that the reduced ICP instability observed in THAM treated patients may account for this improvement. Is THAM effective in buffering traumatized brain tissue? What factors account for improvement in ICP stability? We addressed these questions in experimental studies utilizing MR spectroscopy to measure brain lactate production and tissue pH in fluid percussed anaesthetized cats. The protocol was designed to match our clinical trial, and brain injured animals were randomized into control, THAM, and hyperventilated groups. We observed that brain lactate production increased with trauma and remained above control at 8 hrs post injury. Lactate production in THAM treated animals was not elevated. Highest lactate production was associated with injured animals treated with sustained hyperventilation.(ABSTRACT TRUNCATED AT 250 WORDS)
