ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

Exorcizing Divergence in Tree‐Ring Density Along the Rocky Mountains
Abstract Briffa et al. (1998), https://doi.org/10.1038/35596 published a seminal paper on the reduced sensitivity of annual tree growth to temperature across Northern Hemisphere treeline stands. By averaging tree‐ring chronologies to sub‐continental means, they found decade‐long trends in maximum latewood density (MXD) progressively diverging from ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Acalolepta aesthetica is a non‐native cerambycid established on the Island of Hawaiʻi. We show its preferred hosts are woody species that are highly valued for agricultural, horticultural and cultural uses. We used a resource selection function to estimate host preferences and found that kukui (Aleurites moluccanus), the state tree, was preferred ...

Chemical changes of polysaccharides in heat-treated European beech wood
This work deals with the influence of different heat treatment temperatures (140, 150, 160, 170, 180, 190, 200, and 210 °C) on changes in sapwood and red heartwood of European beech (Fagus sylvatica L.). According to the results of wet chemistry methods,

ABSTRACT Understanding the oxygen and hydrogen isotopic composition (δ18O and δ2H values, respectively) of plant source water is fundamental for tracing water uptake in ecohydrological studies. However, discrepancies between cryogenic vacuum distillation (CVD)‐extracted soil and xylem water and known plant source water δ18O and δ2H values continue to ...
