Introduction to Population Biology: Interspecific competition and amensalism

摘要: The word ‘competition’ is used in everyday language, and so we all have a feeling for what it means. We tend to think of competition as an active process which individuals are striving common goal, trying outdo each other that there winners losers. In the biological world, individual organisms struggle obtain resources necessary living, such water, light food, can this involving both intraspecific interspecific competition. Darwin talked these processes terms ‘struggle existence’ development his theory natural selection. Defining How do define study rigorous way? Many ecologists prefer operational definition gives us way measuring whether occurring or not. Following logic, I will modify Emlen (1973) follows: Competition occurs when two more species experience depressed fitness (reduced r K ) attributable their mutual presence area . Thus, simple terms, defined inhibition growth. informally measure Chapter 5 (section 5.1), see easy extend logistic growth model include
