Gauss's idea was formed on the basis of his pioneering experimental work. Gauss first observed the competition between two species through experiments. He used two kinds of paramecium which are very similar in classification and ecology, namely, paramecium bicephalum and paramecium giganteum, as experimental materials, and used a Bacillus as feed for culture. When cultured separately, both paramecium species showed typical logarithmic growth. When mixed together, both populations initially increased, but paramecium with double small nuclei increased faster.
After 16 days, only the double-nucleated grass cover worm survived, and the paramecium disappeared completely. The experimental conditions can ensure that there is only food competition between the two paramecium species, and there is no other relationship. Gauss explained that paramecium giganteum disappeared because its growth rate (intrinsic growth rate) was slower than that of paramecium bipinnatum. Because of the competition for food, fast-growing species will crowd out slow-growing species.
This is a competitive exclusion phenomenon when two species use the same food resources. Competitive exclusion principle, a modern ecologist, made a concise and accurate statement on the Gauss Hypothesis: perfect competitors (with the same niche) cannot exist.
C.f. gauss:
Born in Brunswick, he graduated from the University of G? ttingen, a famous German mathematician and one of the founders of modern mathematics. 1792 entered Brunswick College and began to study advanced mathematics. He independently discovered the general form of binomial theorem, "quadratic reciprocity law" in number theory, prime number distribution theorem and arithmetic geometric average.
1796, a very important achievement in the history of mathematics, the theory and method of drawing a regular 17-sided ruler, was obtained. 180 1 published Arithmetic Research, which laid the foundation of modern number theory. 1804 was elected as a member of the royal society. 18 18 was the scientific adviser of the Danish government, and in the same year, he was the scientific adviser of the Hanover government.
1827 published the general theory of surfaces, which comprehensively and systematically expounded the calculus geometry of spatial surfaces. From 1820 to 1830, the solar observatory was invented. 1833, the world's first telegraph machine was built. 1February 23, 855, died in gottingen.
