- Global satellite monitoring of climate-induced vegetation disturbancesNate G McDowell
Los Alamos National Lab, Earth and Environmental Sciences Division, Los Alamos, NM 87545, USA Electronic address
Trends Plant Sci 20:114-23. 2015..Significant remaining challenges are tied to the ecology of disturbances. To meet these challenges, more effort is required to incorporate ecological principles and understanding into the assessments of disturbance worldwide. ..
- The interdependence of mechanisms underlying climate-driven vegetation mortalityNate G McDowell
Los Alamos National Laboratory, Los Alamos, NM 87545, USA
Trends Ecol Evol 26:523-32. 2011..Here, we outline the observations and experiments needed to test this interdependence and to improve simulations of this emergent global phenomenon...
- Environmental sensitivity of gas exchange in different-sized treesNate G McDowell
Los Alamos National Laboratory, MS D462, Los Alamos, NM, 87545, USA
Oecologia 145:9-20. 2005..The results also imply that the impacts of climate change on the growth and physiology of forest trees will vary depending on the age and size of the forest...
- Homeostatic maintenance of ponderosa pine gas exchange in response to stand density changesNate G McDowell
Los Alamos National Laboratory, Earth and Environmental Sciences Division, MS J495, Los Alamos, New Mexico 87545, USA
Ecol Appl 16:1164-82. 2006..e., greater absolute BAI during drought; however, trees with high A(l):A(s) in low basal area stands also exhibited the greatest sensitivity to drought, i.e., greater relative decline in BAI...
- Mechanisms of plant survival and mortality during drought: why do some plants survive while others succumb to drought?Nate McDowell

- A dynamic soil chamber system coupled with a tunable diode laser for online measurements of delta13C, delta18O, and efflux rate of soil-respired CO2Heath H Powers
Earth and Environmental Sciences Division, MS J495, Los Alamos National Laboratory, Los Alamos, NM 87544, USA
Rapid Commun Mass Spectrom 24:243-53. 2010..Global Change Biol. 2008; 14: 2178). The soil chamber coupled with the TDL was found to be an effective method for capturing soil CO(2) efflux and its stable isotope composition at high temporal frequency...
- Assessing uncertainties in a second-generation dynamic vegetation model caused by ecological scale limitationsRosie Fisher
Earth and Environmental Science Division, Los Alamos National Laboratory, Los Alamos, NM, USA
New Phytol 187:666-81. 2010..We conclude that demographic processes represent a large source of uncertainty in DGVM predictions...
- A new measurement technique reveals rapid post-illumination changes in the carbon isotope composition of leaf-respired CO2Margaret M Barbour
Landcare Research, PO Box 69, Lincoln 8251, New Zealand
Plant Cell Environ 30:469-82. 2007..The strong (13)C enrichment that followed a high light-to-dark transition coincided with high respiration rates, suggesting that so-called light-enhanced dark respiration (LEDR) is fed by (13)C-enriched metabolites...
- An investigation of hydraulic limitation and compensation in large, old Douglas-fir treesNate G McDowell
Department of Forest Science, Oregon State University, Corvallis, OR 97331, USA
Tree Physiol 22:763-74. 2002..However, compensation may have a cost; for example, the greater DeltaPsi of the largest trees was associated with smaller tracheid diameters and increased sapwood cavitation, which may have a negative feedback on kl and gs...
- Canopy and hydraulic conductance in young, mature and old Douglas-fir treesNathan Phillips
Geography Department, Boston University, Boston, MA 02215, USA
Tree Physiol 22:205-11. 2002..A hydraulic mass balance suggests that greater sapwood conductivity in 60-m trees compared with 32- and 15-m trees is a likely cause for the departure of the above rankings from those predicted by height and leaf-to-sapwood area ratio...
