BIOL1012 Lecture Notes - Lecture 26: Heterotroph, Krill, Humid Continental Climate
Document Summary
Biology: sections 53. 2, 53. 3, 53. 6, 54. 2, and 54. 3. Communities: inter-specific interactions: the predator is about to substantially (and negatively) affect the fitness of the prey animal here, potentially changing the genetic structure/variation within the t ngara frog population. Births and immigration add individuals to a population. Deaths and emigration remove individuals from a population. Anderson et al. (2011) proceedings of the royal society b doi:10. 1098/rspb. 2011. 0155. Populations grow: the idealised case: if the organisms are free to reproduce at their physiological limit (rmax) the population grows exponentially (aka geometrically) Figure 53. 7: in a simple case where there are 2 births per death per capita (e. g. rmax=2-1=1) the population increases in direct proportion to its size, at generation 6 n=500, at gen. 7 n=1000, and at gen. 8 n=2000: if there are 1. 5 births per death then rmax=0. 5, and population growth is much slower, n=500 at gen. 12, and 750 at gen. 13.
