Factors that decrease population growth can be defined as environmental stress including limitations in food, predation, and other density-dependant factors (Sibley & Hone 2002). However, many sources of environmental stress affect population growth, irrespective of the density of the population. Density-independent factors, such as environmental stressors and catastrophe, are not influenced by population density change.
Zoan was the capital of the Hyksos rulers, or shepherd kings, in whose time Jacob came into Egypt, and their monuments have been found at the site, which favors the conclusion that its plain was that land of Rameses (Genesis 47:11 Exodus 12:37; see RAAMSES) where the Hebrews had possessions under Joseph.
Name and originsEdit. The food has been associated with Zuo Zongtang (Tso Tsung-t'ang) (1812â1885), a Qing dynasty statesman and military leader from Hunan Province. Zuo himself could not have eaten the dish as it is today, and the dish is found neither in Changsha, the capital of Hunan Province, nor in Xiangyin County, where Zuo was born. Moreover, Zuo's descendants, who are still living in Xiangyin County, when interviewed, say that they have never heard of such a dish.
