Nat Commun
. 2017 Mar;
8:14800.
PMID: 28348371
Dust provides ecosystem-sustaining nutrients to landscapes underlain by intensively weathered soils. Here we show that dust may also be crucial in montane forest ecosystems, dominating nutrient budgets despite continuous replacement...

Oecologia
. 2017 Mar;
80(2):284-288.
PMID: 28313121
Annual estimates of surface soil nitrogen transformations were determined using an in situ method in four different subarctic vegetation types within a watershed in southwestern Alaska. The net nitrogen mineralization...

Trends Ecol Evol
. 2011 Jan;
13(6):232-5.
PMID: 21238277
Hydraulic lift is the process by which some deep-rooted plants take in water from lower soil layers and exude that water into upper, drier soil layers. Hydraulic lift is beneficial...

Trends Ecol Evol
. 2011 Jan;
12(4):139-43.
PMID: 21238010
Experiments suggest that plants and soil microorganisms are both limited by inorganic nitrogen, even on relatively fertile sites. Consequently, plants and soil microorganisms may compete for nitrogen. While past research...

Ecol Appl
. 2010 May;
20(3):663-83.
PMID: 20437955
Disturbances alter ecosystem carbon dynamics, often by reducing carbon uptake and stocks. We compared the impact of two types of disturbances that represent the most likely future conditions of currently...

. 2006 Jun;
149(4):668-75.
PMID: 16804703
The well-known deceleration of nitrogen (N) cycling in the soil resulting from addition of large amounts of foliar condensed tannins may require increased fine-root growth in order to meet plant...

. 2004 Feb;
139(2):288-97.
PMID: 14767756
Genetic variation in dominant species can affect plant and ecosystem functions in natural systems through multiple pathways. Our study focuses on how genetic variation in a dominant riparian tree (...

. 2003 Jun;
39(1):69-82.
PMID: 12812256
We investigated the environmental water sources used in mid-summer by three Sonoran Desert phreatophytic riparian tree species, Salix gooddingii, Populus fremontii, and the exotic Tamarix spp., at sites that differed...

PMID: 12812252
Numerous researchers have used the isotopic signatures of C, H, and O in tree rings to provide a long-term record of changes in the physiological status, climate, or water-source use...

PMID: 11276417
We investigated leaf gas exchange responses to leaf temperature, leaf-to-air vapor pressure deficit (VPD), and predawn and midday shoot water potential (psipd and psimd, respectively) of two native Sonoran Desert...
