2/12 Class Business Just a reminder: NO HOODS No even tucked in. This is your last warning then they are mine No hats in the building. Even if you take it off in the class. No headphones, even hanging out of your shirt! This is your last warning then they are mine! ID’s and tucked in shirts at all times! Clear backs and purses must be small! Tardies- NO MORE! We will move to more of drastic measure

Dispersion Notebook questions Pg. 18 1. What is the most common type of dispersion? a. List reasons why this pattern is most common. b. Give 3 examples of this pattern in a real ecosystem 2. What is the likely dispersion pattern of fish that swim in schools, seabird nesting on a small field, and thistles growing in a fairly uniform field? 3. What affects the size of populations? Think broadly and what affects the human and non-human population? 4. What would be the likely cause of bushes of one species growing in one area in a uniform spaced pattern? a. random distribution of seeds b. interactions among individuals in the population c. chance d. equal nutrient supplies in that area e. variation in sunlight 5. Define dispersion:

2/12 Objective • Discover how patterns of survivorship relate to the classic three types of survivorship curves.

Survivorship curves Age diagrams show us the relative number of individuals at each age. Survivorship curves can show us characteristics of the population. Key Point #1: Survivorship curves show us survival characteristics of the population.

Describe the characteristics of these populations:

Describe the characteristics of these populations:

Describe the characteristics of these populations:

Compare and contrast these organisms to one another.

Survivorship Curves Type I: • High survival rate in young • Effective parenting • Overall low death rates Type II: • Constant death rate • Limited parenting Type III: • • High death rate in young No parenting A lot of offspring because so many die Once survive till a certain age, high survival rate

Match the curves to the populations Type I Type 2 Type 3

Let connect the dots

Survivorship Curve Lab Directions: In a group of four, complete the lab. Read ALL directions carefully before beginning. Your lab information will be on page. 20 Bubble Lab. Person A: Timer Person: Bubbler Person C: Counter Person D: Recorder Time: 25 minutes Noise: 2 (with group)

Survivorship Curve Lab Directions: After you have read the lab, as a group formulate your hypothesis about the following question. Which population will have a higher life expectancy? Population A or B? Every member of the group will need the hypothesis, chart, conclusions and post lab questions completed in their notes. 1, 2, 7, 8, 9

2/12 Exit Ticket #5 Name: _____ period: 2 date: 2/12 Score: _______/4 QP: 1. What would likely be the cause of bushes of one species growing in one area in a uniform spacing pattern? a. random distribution of seeds b. interactions among individuals in the population c. chance d. the equal nutrient supplies in that area 2. What type of survivorship curve would a human being display? 3. What type of growth model do populations show in a stable environment (logistical or exponential)? 4. True or false, Frogs show type I curve because they take good care of their offspring.

9/9 Exit Ticket #4 1. What would likely be the cause of bushes of one species growing in one area in a uniform spacing pattern? a. random distribution of seeds b. interactions among individuals in the population c. chance d. the varied nutrient supplies in that area e. variation in sunlight B, human plants the seeds in that pattern 2. What is the likely dispersion pattern: • fish that swim in schools- Clumped • seabird nesting on a small field- Uniform • thistles growing in a fairly uniform field? - Random 3. What is the most common type of dispersion? Why? Clumped because of protection, hunting, mating, and social behavior
