Measuring Water Availability and Uptake in Ecosystem Studiesfor plant uptake, and the transport of water through the plant (Fig. 13.1). Since many of these methods are also used in physiological ecology, our chapter is designed to bridge the gap between the scales of physiological and ecosystem ecology, as a foundation for other contributions in this book.作者: 壓碎 時(shí)間: 2025-3-22 21:38
