â¢â¯No I or E â¢â¯Linear density dependence (of b and/or d on population) â¢â¯Constant carrying capacity â¢â¯No genetic structure â¢â¯No age or size structure â¢â¯No time lag. Logistic Growth Pearl and Reed (1920) derived the logistic equation and used it to predict a carrying capacity for the U.S. population, using census data. The logistic curve fit the U.S. data well, through 1950. After that, however, the actual population size differed considerably from the predicted curve.
Zelda Sayre Fitzgerald was born in Montgomery, Alabama. She was strikingly beautiful and intelligent, but wild and impatient with learning. In the summer of 1918, shortly after graduating from high school, she met an Army lieutenant and aspiring novelist named F. Scott Fitzgerald at a dance at the Montgomery Country Club.
Fitzgeraldâs mother, Mary (Mollie) McQuillan, was the daughter of an Irish immigrant who became wealthy as a wholesale grocer in St. Paul. Both were Catholics. Edward Fitzgerald failed as a manufacturer of wicker furniture in St. Paul, and he became a salesman for Procter & Gamble in upstate New York.
