BIO205H5 Lecture Notes - Lecture 12: Logistic Function, Intraspecific Competition, Global Warming
Document Summary
The environment (including amount of space available; density) Limited resources: we usually assume that the k value remains constant. K: the black-throated blue warbler is a typical migratory songbird. It feeds in the cold, but doesn"t breed in the caribbean or panama. Their mortality rates differed in different types of habitats. Its average monthly survival rate was much lower during migration. Researchers looked at their breeding patterns and found that fecundity decreased with increased population size. The higher the adult nest was, the lower the young fledged per territory (might be due to competition). Jamaica there is less stable factors than in new hemisphere. Soi, the stronger the intensity of el nino. In their breeding areas there is a higher impact of survival in the habitats that are located in the caribbean. Predation (the larger the population, the more predators there are). Bio205: density-independent factors: natural disasters (tornadoes, floods, etc).
