Document Summary
Eyes that are in front of face for better depth perception: great apes hominids large bodied, long arms, short legs, no tails. Conservation biologists apply these data to preserve species and restore environments. If a population consists primarily of young individuals with high survival and reproductive rates, the population size should increase over time. Individuals with high fecundity tend to grow quickly, reach sexual maturity at a young age, and produce many small eggs or seeds. Individuals from species with high survivorship tend to grow slowly and invest resources in traits that reduce damage from enemies and increase their own ability to compete for water, sunlight, or food. Population growth: a population"s growth rate is the change in the number of individuals in the population per unit time. Is growing: per capita death rate is greater, r is (-) population declines. Depends on a large number of factors: food, space, water, soil quality, and resting or nesting sites.
