This paper examines the stable outcomes of organization choice between single-plant and multi-plant under asymmetric two regions. A typical implicit assumption on monopolistic competition models for trade and economic geography is that firms can produce and sell only at one place. This paper allows endogenous determination of the number of plants in a new economic geography model. In particular...

abstract. vegetation of each region is one of the most important phenomena of nature and is the best guide to judge about the ecological sciences of that region because the plants are resistant organisms that have endured the long term conditions of all kinds of environmental conditions for a long period of time and have adapted with environmental stresses. therefore floristical investigation o...

Geological and climatological processes that have impacted the biota of the Northern Hemisphere during the Tertiary are expected to yield little resolution when area cladograms are compared without taking the timing of diversification into account. In an attempt to establish a set of appropriate phylogenetic comparisons, we distinguished between a Pacific track involving (minimally) China, Japa...
