As you become more familiar with the literature in behavioral ecology, you will encounter the terms “individual fitness” and “inclusive fitness” with increasing frequency. What is the primary difference between individual and inclusive fitness?
Homework Answers
individual fitness is the total number of offsprings that any individual bring into existance whereas Inclusive fitness is the total count of offsprings equivalents that an individual make part of it and saves it otherwise supports through their own behaviour

3. Why might a behavioral ecologist say that the ecology of females has more to say about the evolution of the mating system of a species than the ecology of males? (2 marks) a. Because receptive females are usually in short supply for males, not the other way around. b. Because male competition for mates is relatively unimportant in the definition of animal mating systems. c. Because females are the key for the preservation of the species; their reproduction, not...

In the literature you become aware of a pattern in parasite infections of birds and fish. While exceptions exist, birds tend to have more diverse helminth communities and greater abundance of parasites than fish. You seek for an explanation. In a eureka moment, you believe it is due to ????? What features do you believe contribute to this pattern.

Draw a model or concept map linking at least these evolutionary concepts. You are free to add more. When you make a link between two ideas you must write what links the concepts above the arrow. Just drawing arrows does not help build your understanding. Words required to appear in your map: allele frequencies evolution non-random mating migration natural selection genetic drift Hardy-Weinberg equilibrium population individual speciation sexual selection fossil record macroevolution phenotypic plasticity kin selection coevolution population size species...

Question 64. Earth has experienced five previous mass extinction events Many ecologists now believe we are experiencing a sixth mass extinction. How does this current mass extinction differ from previous extinction events? The background extinction rate now is much higher now than in previous a. extinction events b. The background rate of extinction is higher now than the rate of biodiversity so the current extinction event is more pronounced than previous ones. There are no differences in the previous and...

ADVANCE STUDY ASSIGNMENT: COULOMB'S LAW PURPOSE of tl of this exercise is to become familiar with the force between electric point charges which is descrbed by Coulomb's law. In particular, we will investigate the force's inverse-square dependence on separation distance between charges. DISCUSSION A basic characteristic of electric charge is that charges exert forces on each other, like charges positive-positive and negative-negative) repel each other while opposite charges (positive- and constitute a Newton's third-law pair; that is, they are equal...

Question 1. You are a cancer researcher studying skin cancer cells that have become metastatic (ie. they've migrated from the site of the original tumor to establish new secondary tumors). You analyze skin samples from an unaffected patient and from one with the metastatic cancer. After a series of detergent solubilization and centrifugation steps, you separate pellet samples from each tissue type by gel electrophoresis and find the following results: skin normal cancer tissue tissue 250 Da 120kDa 75kDa- 60kDa...
