37 In coastal forests of the Pacific Northwest, young coniferous plantations typically contain a 38 mixture of planted and natural Douglas-fir (Pseudotsuga menziesii) and western hemlock (Tsuga 39 heterophylla). Swiss needle cast (SNC) disease inhibits the growth of Douglas-fir to varying 40 degrees in these stands, depending on SNC severity. In addition to the value differential between 41 Dou...

Charles Cobb and Paul Douglas in 1928 used data from the US manufacturing sector for 1899-1922 to introduce what is known today as Cobb-Douglas production function that has been widely economic theory decades. We employ R programming language fit formulas parameters of generated by authors recently via bi-Hamiltonian approach same set utilized Douglas. conclude output elasticities total factor ...

Tree species response to climate change-induced shifts in the hydrological cycle depends on many physiological traits, particularly variation in water relations characteristics. We evaluated differences in shoot water potential, vulnerability of branches to reductions in hydraulic conductivity, and water source use between Pinus contorta Dougl. ex Loud. var. latifolia Engelm. (lodgepole pine) a...
