The Intermediate Disturbance Hypothesis Suggests Species Richness
Low rates of disturbance, competitively dominant species would outcompete all other species (K selected) At high levels of disturbance, species would be continually driven extinct and only good colonists and well disperse (r-selected) would persist. Intermediate disturbance, species richness is greatest in areas where disturbances are neither too large nor too small but are of intermediate size.

#Unit 2. Cellular Organization

In G-banding, chromosomes are first gently heated and then exposed to Giemsa stain; this DNA dye preferentially darkens certain regions to produce alternating dark and light G bands. Each G band is a very large segment of DNA from 1 to 10 Mb in length, containing many loops. With high-resolution G-banding techniques, a standard diploid human karyotype of 46 chromosomes is seen to contain hundreds of dark and light G bands. Not used in plants.
