Foliage, fine-root, woody-tissue and stand respiration in Pinus radiata in relation to nitrogen status.
We measured respiration of 20-year-old Pinus radiata D. Don trees growing in control (C), irrigated (I), and irrigated + fertilized (IL) stands in the Biology of Forest Growth experimental plantationExpand

The relationship between tree height and leaf area: sapwood area ratio
Abstract. The leaf area to sapwood area ratio (Al:As) of trees has been hypothesized to decrease as trees become older and taller. Theory suggests that Al:As must decrease to maintain leaf-specificExpand

Stomatal conductance and photosynthesis vary linearly with plant hydraulic conductance in ponderosa pine
Recent work has shown that stomatal conductance (gs) and assimilation (A) are responsive to changes in the hydraulic conductance of the soil to leaf pathway (KL), but no study has quantitativelyExpand

Woody tissue maintenance respiration of four conifers in contrasting climates
We estimate maintenance respiration for boles of four temperate conifers (ponderosa pine, western hemlock, red pine, and slash pine) from CO2 efflux measurements in autumn, when constructionExpand

Evidence that hydraulic conductance limits photosynthesis in old Pinus ponderosa trees.
We tested the hypotheses that hydraulic conductance is lower in old (about 250 years old and 30 m tall) compared to young (about 40 years old and 10 m tall) Pinus ponderosa Dougl. ex Laws. trees andExpand

Quantifying structural and physiological controls on variation in canopy transpiration among planted pine and hardwood species in the southern Appalachians
Recent studies have shown that planted pine stands exhibit higher evapotranspiration (ET) and are more sensitive to climatic conditions compared with hardwood stands. Whether this is due toExpand

Tree regeneration and future stand development after bark beetle infestation and harvesting in Colorado lodgepole pine stands
In the southern Rocky Mountains, current mountain pine beetle (Dendroctonus ponderosae Hopkins) outbreaks and associated harvesting have set millions of hectares of lodgepole pine (Pinus contortaExpand

Dark respiration of pines
Plant respiration is a large, environmentally sensitive component of the carbon balance for pine ecosystems and can consume >60% of the carbon fixed in photosynthesis. If climate, genetics, or carbonExpand

A comparison of sap flux-based evapotranspiration estimates with catchment-scale water balance
Many researchers are using sap flux to estimate tree-level transpiration, and to scale to stand- and catchment-level transpiration; yet studies evaluating the comparability of sap flux-basedExpand

Changes in transpiration and foliage growth in lodgepole pine trees following mountain pine beetle attack and mechanical girdling
The recent mountain pine beetle outbreak in North American lodgepole pine forests demonstrates the importance of insect related disturbances in changing forest structure and ecosystem processes.Expand
