New Phytologist, EarlyView.Summary The island rule predicts gigantism or dwarfism in body size of island species relative to their mainland counterparts. However, whether other functional traits shift and whether trait–trait associations on islands differ between species and community levels remains unclear. We measured 13 carbon‐ and water‐related functional traits in 37 shared

Allometry of Sapwood Depth in Five Boreal Trees [PDF]
Forests, 2017 This paper analyzes sapwood variability and allometry within individuals of Populus tremuloides, Pinus contorta, Pinus banksiana, Picea mariana, and Picea glauca. Outside bark diameter at breast height (DBH) and sapwood depth (sd) in four cardinal directions were measured in individuals in stands in Alberta and Saskatchewan, Canada.

The quality comparison of particleboards produced from heartwood and sapwood of european larch
Maderas: Ciencia y Tecnología, 2019 In this paper, the impacts of heartwood and sapwood usage on the physical, mechanical, and surface properties and formaldehyde emission of particleboard are investigated. European Larch (Larix decidua) trees are chosen as a raw material.

Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]
, 2017 The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient

Measurement of sap flow dynamics through the tomato peduncle using a non-invasive sensor based on the heat field deformation method [PDF]
, 2013 Recent contradicting evidence on the contributions of xylem and phloem to tomato fruit growth highlights the need for a more thorough insight into the dynamics of sap flow through the tomato peduncle. In fact, knowledge on sap flow dynamics through small

New Phytologist, EarlyView.Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Trade-offs Between Water Transport Capacity and Drought Resistance in Neotropical Canopy Liana and Tree Species [PDF]
, 2016 In tropical forest canopies, it is critical for upper shoots to efficiently provide water to leaves for physiological function while safely preventing loss of hydraulic conductivity due to cavitation during periods of soil water deficit or high ...

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate
New Phytologist, EarlyView.Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

, 2020 As the earth's climate continues to change, forests within a diverse set of biomesare experiencing increasingly frequent, severe, and longer periods of drought stress.The continued rise of global temperatures could radically alter the composition and structure of forests in many regions (Van Mantgem, 2007).
