Variation in xylem structure and function has been extensively studied across different species with a wide taxonomic, geographical and ecological coverage. In contrast, our understanding of how xylem of a single species can adjust to different growing conditions remains limited. In this thesis,...

Evaluation of centrifugal methods for measuring xylem cavitation in conifers, diffuse and ringporous angiosperms

Hacke, U.G., Taneda, H., Li, Y., Sperry, J.S., Bush, S.E.
• A centrifugal method is used to measure ‘vulnerability curves’ which show the loss of hydraulic conductivity in xylem by cavitation. Until recently, conductivity was measured between bouts of centrifugation using a gravity-induced head. Now, conductivity can be measured during centrifugation....

Modelling water table depth effects on net ecosystem CO2 exchange of two contrasting forested peatlands – a tropical bog and a boreal fen
DownloadFall 2015
Peatlands have been accumulating carbon (C) in wet soils under shallow water table (WT) over millennia. Increased frequency and intensity of droughts and artificial drainage for promoting agriculture have recently been causing peatland WT depth (WTD) drawdown. This could alter peatland C balance...
