Answer:
competitive exclusion.
Explanation:
When species from the same biological community explore very similar ecological niches, competition among them for less available resources in the environment is instituted. It is common, for example, that plant species whose roots use the same portion of the soil compete for water, minerals and other resources.
Knowing this, Russian biologist Georgyi Frantsevich Gause formulated the Gause principle, or competitive exclusion principle, the theory that ecological niches are unique to each species, and for two or more of them to coexist in the same habitat, it is necessary that their niches have different and sufficient characteristics.
Gause proposed this theory based on several observations that led him to conclude that if two or more species explore exactly the same ecological niche, the competition established between them is so sharp that coexistence becomes impossible. This can cause a loss in species diversity, and that is exactly what Robert Paine observed in his studies.
Answer:
This article outlines some general aspects of the Magan and Dilmun trade and goes on to examine the Umm an-Nar pottery discovered in the tombs of the Early Dilmun burial mounds of Bahrain. These ceramics are of particular interest because they indirectly testify to Dilmun’s contact with Magan in the late third millennium. In this article, thirty vessels of seven morphological types are singled out. By comparison with the material published from the Oman peninsula the Bahrain collection is tentatively dated to c.2250–2000 BC. The location of the Umm an-Nar pottery within the distribution of burial mounds reveals that its import was strongly associated with the scattered mounds of Early Type. It is demonstrated that the frequency of Umm an-Nar pottery declined just as the ten compact cemeteries emerged c.2050 BC. The observed patterns are seen as a response to the decline of Magan and the rise of Dilmun.
