Unit 1

Answers are at the end of this page.

1. Richness in population work means reproductive vigor. T = 1 F = 2 ?

2. A manager working with 3 species, has 30, 40, and 30 in each species. Through management he achieved new abundance of 20, 40 and 40. When did he (she) have the highest modified Simpson Diversity Index before (1) or after (2) management?

3. Which is the best buy, (1) 1000 units with a failure probability of about 0.25 and price of $350 or from another supplier offered with (2) a failure rate of about 0.20 for $380? Give an answer of 1 or 2.

4. A survival curve looks like 1, 2 or 3 (given that time or years is the horizontal axis)?

5. Given Nt = No (l + r)t and a rate of 2% increase, how large will a population of 1200 elk be after 2 years? (1) 1,200, (2) 10,800, (3) 1248, (4) 1328, (5) 4800.

6. The "icebox principle" is an expression of the importance of winter cover for animal populations. True = 1, False = 2

7. Phenology is the study of the seasonal timing or occurrence of biological events. True = 1, False = 2

8. A manager compared two areas for which he (she) was responsible. Compartment A had 16 key species, compartment X had 20 species. There were 12 of the same species occurring on both area A and X. How similar were the areas? A primary similarity index was (1) 0.67, (2) 0.80, (3) 0.875, (4) 0.50.

9. A triangular acre(equilateral) has less edge than a circular acre T = 1, F = 2.

10. Maximum habitat corners throughout a management area can be gotten by using a spatial pattern of (1) hexagons, (2) equilateral triangles, (3) squares, (4) ameboid patterns.

11. Fulminate means:

  1. make rust colored
  2. use fire and explosives in management
  3. appear to become angry in group meeting
  4. create very long lengths of edge
  5. modify population natality rates

12. A biologists got a wonderful equation using a logarithmic transformation of bird richness (R) on a military area. He (she) used log10 (R + 1) as the dependent variable. The equation was

y = 43.6 - 0.45 (YEAR)

where "year" was 80 to 93. For 1990 the equation produced a value of y = 3.1. The birds on the area were (1) 3.1, (2) log (3.1), (3) 1259, (4) antilog (0.45), (5) 1258.

13. On the above area, the equation indicates that the bird population is (1) increasing (2) decreasing, or (3) stable.

14. An acre is an area of 43,560 square feet. True = 1 False = 2

15. The present value of $10,00 for a period of 30 years and discounting rate of 0.08 is (1) $3,033, (2) $994, (3) $24,000, (4) 333, (5) $4166

16. The area of my wildlife waterhole is 10,000 square feet. It is a perfect circle. What is the length of its edge or shoreline? (1) 254, (2) 354, (3) 454, (4) 554, (5) more than 554 feet.

17. Policy: A clearing should be no more wide than twice the height of the tallest tree in the area. Trees in the area are 20 meters tall. How much linear edge (meters) is there in a long rectangular area of 1 hectare (which has 10,000 square meters)? (1) 580, (2) 1400, (3) 4000, (4) 1080.

18. A bear caused direct loss of $3200 to a farmer in broken bee hives and lost revenue for 2 years. This is properly called (1) injury or (2) damage.

19. The F-13 actions are for

  1. subversion
  2. manipulating succession
  3. managing faunal space
  4. manipulating fertility and fecundity

20. The general concept of a natural resource has 4 major components: these are valued energy or matter, time, space, and .... The missing component is (1) leadership, (2) complexity, (3) entropy, (4) variety, (5) subversion.

21. Any major land disturbance can initiate a succession curve. True = 1 False = 2

22. The maximum height attained by a "succession curve" or an "ecological production function" is determined by

  1. amount of edge and interspersion
  2. land area affected
  3. soil moisture and site factors
  4. starting date

23. "Aggregates" in the "concept of the aggregates" refers to:

  1. rocky soil conditions
  2. total areas under wildlife curves
  3. cumulative impact analyses statement
  4. total areas in a landscape

24. The alternative to volume or area regulation in forests is:

  1. alpha regulation,
  2. beta regulation,
  3. financial regulation, or
  4. Korzybsky regulation.

25. The doubling time (years) for a population with a rate of 0.07 is: (1) 3, (2) 10, (3) 14, (4) 117

26. One kilogram/hectare is equivalent to approximately how many pounds/acre? (1) 1, (2) 3, (3) 5, (4) 12, (5) 21.

27. An "AUM" is an animal-unit-month. True = 1 False = 2

28. A stochastic model is one which is useful in GIS for accurate survey work, especially of wetlands. True = 1 False = 2

29. The multiple-use, sustained yield act was developed first for the BLM. True = 1 False = 2

30. A "tolerant" tree species is classically defined as one that:

  1. can be successfully moved to other regions
  2. can survive with little sunlight
  3. can withstand many types of pollutants
  4. can survive the vibrations of urban development
  5. can withstand long flooded periods

31. Forest stand age has no effect on the computation of the volume of the "edge tunnel." True = 1, False = 2

32. Ecological density of animals will usually be higher than crude density for the same area. True = 1, False = 2
