Our lab examines terrestrial plant dynamics from the individual plant to the community level through the lens of plant water relations. Plant function is fundamentally constrained by the availability of water, which varies in complex ways across space and time. Plants engage numerous, diverse strategies to optimize growth and reproduction when water is available, while limiting losses when it is not. How these adaptations to a variable and uncertain environment translate into patterns of productivity, population dynamics, community structure and vegetation response to climate change is the overarching question that motivates our research. Research methods span the gamut from field research, greenhouse experiments and mathematical modeling.
Nathan Custer presented on his research at the Ecological Society of America Meeting in Portland. The title of his presentation was "Effect of transplant size on early survivorship". The paper was presented in a session on "Multiple Common Garden Experiments for Meeting Restoration Challenges: Difficulties and Potential Pitfalls" organized by Susanne Schwinning and Lesley DeFalco.

The lab welcomes two new graduate students:
Kayla Sustaita will examine the effects of adaptive rotational grazing on soil characteristics.
Logan Maxwell will investigate best restoration practices for abandoned oil and gas exploration fields in Utah.
The lab was awarded two federal grants in 2015:
NSF proposal : DEB-1557176: "Collaborative Research: Hydrological tipping points and desertification of semi-arid woodlands".
The DOD Legacy Award HQ0034-16-2-0006: "Characterizing Mojave Desert shrub ecotypes to establish seed transfer zones for military range restoration".
