Remote sensing of radiation intercepted by vegetation to estimate aboveground net primary production across western Oregon

Creator:

Law, Beverly E.

Abstract:

Remote sensing of variables necessary to estimate net primary production of vegetation over large temporal and spatial scales has been a goal of climate change research. This thesis consists of two studies that address the reliability of satellite and airborne sensors to quantify a basic component of all production models,...

The importance of maintenance respiration by living cells in the sapwood of subalpine conifers

Creator:

Ryan, Michael G.

Abstract:

Xylem conducting tissue or sapwood is an important storage organ for water, carbohydrates, and nutrients, and this storage helps trees accommodate environmental change. However, the living ray parenchyma cells in sapwood, which store the carbohydrates and nutrients, require energy for maintenance. I examined how sapwood maintenance costs vary among species,...
