Measuring the Sap Flow of Eucalyptus Trees
نویسندگان
چکیده
We describe the design and implementation of Savia, a sensor network system for measuring the sap flow of eucalyptus trees. Unlike prior sensor network systems, which generally take a vertically integrated approach and build everything from scratch, Savia is built out of several existing sensor systems. The difficulties we encountered when combining these systems demonstrate why a vertically integrated approach is more common. Based on our experiences composing Savia, we suggest two key abstractions that an OS should provide in order to allow sensor networks to grow beyond the current approach of writing everything from scratch.

Water use pattern and canopy processes of cashew trees during a drying period in West Africagoo
Water flux in a young, 4-year old, cashew (Anacardium occidentale L.) plantation was studied over a dry season, from November 2001 to March 2002, in the forest-savannah transition zone of Ghana, West Africa. The temperature-difference method was used over this five-month period to quantify the diurnal and day-to-day whole-tree sap flow (Qt) and hence the canopy scale transpiration (Ec). M...

Xylem sap flux density (Fd) was measured, on a 43-year-old (mature) and three 4-year-old (young) mango (Mangifera indica L.) trees, using Granier-type probes. The relative influences of environmental variables were examined under well-watered condition. Circumferential variation in Fd was also investigated by placing sensors on the north, south-west and south-east sides of the mature tree. Sap ...
متن کاملTree Species with Photosynthetic Stems Have Greater Nighttime Sap Flux
An increasing body of evidence has shown that nighttime sap flux occurs in most plants, but the physiological implications and regulatory mechanism are poorly known. The significance of corticular photosynthesis has received much attention during the last decade, however, the knowledge of the relationship between corticular photosynthesis and nocturnal stem sap flow is limited at present. In th...
متن کاملThe effect of fertilization on sap flux and canopy conductance in a Eucalyptus saligna experimental forest
Land devoted to plantation forestry (50millionha) has been increasing worldwide and the genus Eucalyptus is a popular plantation species (14millionha) for its rapid growth and ability to grow well on a wide range of sites. Fertilization is a common silvicultural tool to improve tree growth with potential effects on stand water use, but the relationship between wood growth and water use in respo...
متن کاملEvaluation of the heat pulse velocity method for measuring sap flow in Pinus patula
Information on the water use of Pinus patula plantations is required to predict the impact of forest plantations on water resources in South Africa. The heat pulse velocity (HPV) method is a promising technique for measuring water use by trees, and has been shown to measure sap flows accurately in a variety of hardwood trees. This method has not been sufficiently verified for pine trees where t...
