Jacobsen, Anna

Anna Jacobsen is a Senior Professor at California State University, Bakersfield, specializing in plant ecology and tree physiology. Her research focuses on xylem structure and function, particularly vessel diameter polymorphisms, embolism resistance, and wood formation in arid-land shrubs such as *Atriplex* species. Recent publications examine sap flow through embolized networks, intraspecific variation in xylem traits, and the functional role of tracheids in embolism tolerance. Her work integrates forest ecology and plant physiology to address shrubland resilience under climate stress and altered disturbance regimes. She has contributed foundational evaluations of Carlquist’s wood vulnerability indices and is recognized for advancing mechanistic understanding of drought-induced hydraulic failure.
