Physiological Responses of Loblolly Pine and Douglas-fir Seedlings from Various Provenances to Timing and Frequency of Drought Stress

Creator:

Mosel, Jamie E.

Abstract:

Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...

Approaches for Characterizing Plant Physiological Responses to Environmental Stress

Creator:

Marias, Danielle E.

Abstract:

It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

effect of leaf age and heat stress duration (45 min or 90 min) on whole-plant physiological responses
The expression of functional traits during seedling establishment in two populations of Pinus ponderosa from contrasting climates

Creator:

Kerr, Kelly L.

Abstract:

Vegetation patterns and species distributions are strongly linked to soil moisture regimes, and populations within a species from contrasting climatic regimes could exhibit differences in the degree to which certain functional traits related to establishment are expressed. Tree seedling survival is crucial for forest regeneration, and thus may be a...
