The model gives\\na consistent, full explanation of the w-p trajectories of populations starting with any\\ninitial density. The larger value of the relative mortality rate with respect to biological\\ntime of a population, which is governed by the 3/2 power law of self-thinning, plays an\\nimportant role in relieving the C-D effect, so that the w-p trajectories asymptotically\\napproach the self-thinning line on logarithmic coordinates at the earlier stage of\\ngrowth. The survivorship curve is divided into three types owing to initial density:\\nlogistic, exponential and cologistic types of decrease. All populations tend to decrease\\nexponentially in number at the same rate of relative mortality after a sufficient lapse of\\ntime, irrespective of their initial density. The populations decreasing exponentially in\\nnumber follow the 3/2 power law of self-thinning. The carrying capacity of yield is\\nexplicitly defined as a function of biological time, so that it is concluded that the\\ncarrying capacity increases exponentially with increasing biological time. An\\napproximated expression of the model for the w-p trajectory is proposed and is\\nconfirmed to mimic well the time-trajectories of mean stem volume and density during\\nthe development of eastern white pine (Pinus strobus L.) plantations.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/11818"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0286-9640"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250774"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理学部紀要"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of the College of Science.
