Contrasting Hydraulic Strategies in Two Tropical Lianas and Their Host Trees

Creator:

Johnson, Daniel M., Domec, Jean-Christophe, Woodruff, David R., McCulloh, Katherine A., and Meinzer, Frederick C.

Abstract:

• Premise of the Study: Tropical liana abundance has been increasing over the past 40 yr, which has been associated with reduced rainfall. The proposed mechanism allowing lianas to thrive in dry conditions is deeper root systems than co-occurring trees, although we know very little about the fundamental hydraulic physiology...

Bordered pit structure and function determine spatial patterns of air-seeding thresholds in xylem of Doulglas-fir (Pseudotsuga menziesii; Pinaceae) trees

Creator:

Domec, Jean-Christophe, Lachenbruch, Barbara, and Meinzer, Frederick C.

Abstract:

The air‐seeding hypothesis predicts that xylem embolism resistance is linked directly to bordered pit functioning. We tested this prediction in trunks, roots, and branches at different vertical and radial locations in young and old trees of Pseudotsuga menziesii. Dimensions of bordered pits were measured from light and scanning electron micrographs,...
