hunting poisons of the north pacific region.	the hunting poisons of the north pacific region are discussed. the most important one used by the ainu was based on aconitum species (surku or suruku): on hokkaido, to some extent a. japonicum thumb. but probably mainly a. yezoense nakai and a. sachalinense fr. schm.; on southern sakhalin, perhaps a. fischeri reichb., a. maximum pall. ex dc., and/or a. sachalinense fr. schm.; and on the kuril islands, a. maximum pall. ex dc. poison from the japanese stingray dasyatis akajei (müller et henle) (ai ...	1976	781454
leaf morphology and photosynthetic adjustments among deciduous broad-leaved trees within the vertical canopy profile.	photosynthetic acclimation of deciduous broad-leaved tree species was studied along a vertical gradient within the canopy of a multi-species deciduous forest in northern japan. we investigated variations in (1) local light regime and co2 concentration ([co2]), and (2) morphological (area, thickness and area per mass), biochemical (nitrogen and chlorophyll concentrations) and physiological (light-saturated photosynthetic rate) attributes of leaves of seven major species on three occasions (june, ...	2001	11498342
improving disease resistance of butternut (juglans cinerea), a threatened fine hardwood: a case for single-tree selection through genetic improvement and deployment.	approaches for the development of disease-resistant butternut (juglans cinerea l.) are reviewed. butternut is a threatened fine hardwood throughout its natural range in eastern north america because of the invasion of the exotic fungus, sirococcus clavigignenti-juglandacearum nair, kostichka and kuntz, which causes butternut canker. early efforts were made to identify and collect putatively resistant germ plasm, identify vectors and to characterize the disease. more recently, molecular technique ...	2006	16203722
fatty acid profiles, tocopherol contents, and antioxidant activities of heartnut (juglans ailanthifolia var. cordiformis) and persian walnut (juglans regia l.).	the fatty acid and tocopherol compositions of three heartnut (juglans ailanthifolia var. cordiformis) varieties (imshu, campbell cw1, and campbell cw3) were examined and compared with those of two persian walnut (juglans regia l.) varieties (combe and lake). the major fatty acids found in heartnuts and walnuts were identified by gas chromatography as linoleic (18:2n-6), alpha-linolenic (18:3n-3), oleic (18:1n-9), palmitic (16:0), and stearic acid (18:0). polyunsaturated fatty acids were the main ...	2007	17253708
historical effects on local variation in walnut-feeding behavior by the japanese wood mouse, apodemus speciosus.	the japanese wood mouse apodemus speciosus eats large, hard-walled walnuts of juglans ailanthifolia immediately after finding or after hoarding them. however, not all individuals can efficiently eat the nuts. in this study, to examine local variation in the ability to eat walnuts, feeding behavior was compared among nine wood mouse populations, four from mainland honshu, where the walnut tree is distributed, and five from the izu islands (30-100 km south of honshu), which lack the tree species. ...	2012	22303846
