Driscoll A, Bitter N, Sandquist D, Ehleringer J
Proc Natl Acad Sci U S A
. 2020 Jul;
117(31):18161-18168.
PMID: 32719142
While tree rings have enabled interannual examination of the influence of climate on trees, this is not possible for most shrubs. Here, we leverage a multidecadal record of annual foliar...

Ehleringer J, Sandquist D
Oecologia
. 2018 Jun;
187(4):879-895.
PMID: 29955998
Germination, establishment, phenology, and death among three drought-deciduous shrubs were influenced by ENSO/PDO and precipitation, based on 37 years of annual surveys. Encelia farinosa forms near monospecific stands on slopes,...

Ehleringer J, Phillips S, Schuster W, Sandquist D
Oecologia
. 2017 Mar;
88(3):430-434.
PMID: 28313807
Seasonal changes in the hydrogen isotope ratios of xylem waters were measured to determine water sources used for growth in desert plants of southern Utah. While all species used winter-spring...

Schuster W, Sandquist D, Phillips S, Ehleringer J
Oecologia
. 2017 Mar;
91(3):332-337.
PMID: 28313539
Carbon isotope discrimination (Δ) was compared between populations of dominant perennial plant species, differing in life expectancy, in two deserts with contrasting vegetation types. In both deserts, plants of the...

Sandquist D, Ehleringer J
Oecologia
. 2017 Mar;
113(2):162-169.
PMID: 28308193
Reflective leaf pubescence of the desert shrub Encelia farinosa (brittlebrush) reduces leaf temperature and plant water loss, and is considered adaptive in xeric environments. Yet, little is known about intraspecific...

Gerhart L, Harris J, Nippert J, Sandquist D, Ward J
New Phytol
. 2011 Dec;
194(1):63-69.
PMID: 22187970
• While studies of modern plants indicate negative responses to low [CO₂] that occurred during the last glacial period, studies with glacial plant material that incorporate evolutionary responses are rare....

Sandquist D, Ehleringer J
Am J Bot
. 2011 Jun;
90(10):1481-6.
PMID: 21659100
Because leaf pubescence of the desert shrub Encelia farinosa increases in response to drought and influences photosynthesis and transpiration, we hypothesized that differences in water availability across the range of...

Sandquist D, Cordell S
Am J Bot
. 2011 Jun;
94(9):1459-69.
PMID: 21636513
We examined carbon-gain, water-use, and leaf-allocation traits for six tree species of a Hawaiian dry forest to better understand the functional diversity within this threatened ecosystem. Tropical dry forests are...

English N, Dettman D, Sandquist D, Williams D
Oecologia
. 2007 Aug;
154(2):247-58.
PMID: 17724618
The stable isotope composition of spines produced serially from the apex of columnar cacti has the potential to be used as a record of changes in climate and physiology. To...

Gaudinski J, Dawson T, Quideau S, Schuur E, Roden J, Trumbore S, et al.
Anal Chem
. 2005 Nov;
77(22):7212-24.
PMID: 16285668
A number of operationally defined methods exist for pretreating plant tissues in order to measure C, N, and O isotopes. Because these isotope measurements are used to infer information about...
