Effects of invasive insects and fire on forest energy exchange and evapotranspiration in the New Jersey pinelands

Comparison of Tissue Heat Balance- and Thermal Dissipation-Derived Sap Flow Measurements in Ring-Porous Oaks and a Pine
TLDR
The results suggest that 1-cm long sensors are appropriate in species with shallow sapwood, however more corrections may be necessary in ring-porous species.

Contrasting effects of invasive insects and fire on ecosystem water use efficiency
We used eddy covariance and meteorological measurements to estimate net ecosystem exchange of CO2 (NEE), gross ecosystem production (GEP), evapotranspira- tion (Et), and ecosystem water use…

Comparative hydraulic and anatomic properties in palm trees (Washingtonia robusta) of varying heights: implications for hydraulic limitation to increased height growth
TLDR
Findings are consistent with hydraulic compensation in that tall palms may be overcoming the increased path length resistance through smaller, more efficient leaves and lower leaf water potentials than shorter palms.

Resource use and efficiency, and stomatal responses to environmental drivers of oak and pine species in an Atlantic Coastal Plain forest
TLDR
Oaks rely more heavily on groundwater resources but have lower WUE, while pines have larger leaf areas and nitrogen acquisition but lower PNUE demonstrating a trade-off between using water and nitrogen efficiently in a resource-limited ecosystem.

Wet‐ vs. Dry‐Season Transpiration in an Amazonian Rain Forest Palm Iriartea deltoidea
The wet and dry seasons in tropical rain forests can differ in precipitation, soil moisture and irradiance more significantly than often assumed. This could potentially affect the water relations of…

Effects of a prescribed fire on water use and photosynthetic capacity of pitch pines
Although wildfires are important in many forested ecosystems, increasing suburbanization necessitates management with prescribed fires. The physiological responses of overstory trees to prescribed…

Physiological strategies of co-occurring oaks in a water- and nutrient-limited ecosystem.
TLDR
Both oak species showed relatively steep increases in leaf-specific transpiration at low vapor pressure deficit (VPD) values before maximum transpiration rates were achieved, which suggests tight stomatal control over transpiration in both species, although Q. prinus has a more conservative resource-use strategy, while Q. velutina may need to exploit niches that are locally higher in nutrients and water.

Hydraulic architecture and photosynthetic capacity as constraints on release from suppression in Douglas-fir and western hemlock.
TLDR
Assessment of the temporal pattern of release from suppressive shade in Douglas-fir and western hemlock found that hydraulic architecture appeared to constrain release, and trees with more leaf area for a given sapwood area experienced a stomatal limitation on carbon gain.

Intrinsic and extrinsic hydraulic factors in varying sizes of two Amazonian palm species (Iriartea deltoidea and Mauritia flexuosa) differing in development and growing environment.
TLDR
Although height growth rates slow considerably in tall palms, neither species shows evidence that hydraulic factors become limiting because they are able to support much greater leaf areas with similar sap flux densities as shorter palms.
