Okstate wildlife management techniques exam 2 material
Show Answers:

  1. True or false, net gunning is an inappropriate technique for capturing pronghorn antelope because pronghorn antelope are prone to capture myopathy
  2. True or false, an effective method of marking diving ducks such as canvasbacks and redheads is nasal tagging
    False, nasal tags could catch on things and cause them to drown.
  3. True or false, Telazol in an appropriate immobilization drug for raccoons, opossums, and skunks
    True, it's good for pretty much anything according to the book, even reptiles
  4. True or false,  turkey vultures should be marked by leg bands
    False (probably patagial?)

    False, the belt transect method does.
  6. True or false, an antagonist reverses the effects of drugs used to immobilize wildlife species
  7. True or false, an effective method for marking opossums is toe clipping
    False, they are arboreal and rely on their digits
  8. True or false, animals that are higly stressed should not be immobilized with Rompum because "explosive" recoveries are a potential side effect of this drug
  9. True or false, to enhance capture success, small mammal trapping should take place during full moon nights
    False, small mammals are less active on full moon nights because they are more visible to predators
  10. True or false, feather clipping in an appropriate technique for marking songbirds such as American Robin and Blue Jays
  11. True or false, an aerial count of muskrat houses is an example of an index
  12. True or false, deterministic models contain parameter values that randomly vary, which stochastic models contain parameter values that are fixed
    False, stochastic = random, deterministic = fixed
  13. True or false, a mourning dove that has buffy-tipped primary coverts is an immature bird
  14. True or false, when using the Schnabel population estimation method, you do not need to uniquely mark individuals because you only need to distinguish between marked and unmarked individuals
  15. True or false, researchers banding wild turkeys in Oklahoma must have a federal bird banding permit and a collecting permit from the ODWC
  16. True or false, a bal-chatri trap can be used to capture ring-necked pheasants
    False, used on raptors
  17. True or false, during the fall, a wildlife biologist that is capturing birds using mist-netting can age them (i.e. distinguish between young of the year and adult birds) by using the skulling technique
    True, adults will be fully pneumatized (or close to fully) while Hatch-year birds will have openings still
  18. True or false, the therapeutic index of immobilization drugs should be high to allow for errors in estimating body weights and physiological differences among individual animals
  19. True or false, harvested muskrats can be aged by examining the molt pattern on the inside of the pelt
  20. True or false, a while-tailed deer jaw with a tricuspid fourth premolar and 3 molars fully erupted with little or no dentine showing is a 2.5 year-old deer
    False, it would be 1.5
  21. True or false, ring-necked pheasants can be aged by examining the wear and shape of the 9th and 10th primaries
    False, this method can be used for all other gallinacious birds in OK but not pheasants
  22. True or false, according to the Gee et al. (2002) paper, it is appropriate for wildlife biologists to use the tooth wear and replacement techniques for aging older age classes (>2.5 years old) of white-tailed deer
  23. True or false, Bobwhite have a large discrepancy (>10 degrees C) between their average body temperature and lethal body temperature, thus thermal considerations are of little management interest for this species
  24. True or false, sand shinnery oak is a fire intolerant species that cannot resprout following a fire
  25. The distribution of sand shinnery oak is highly dependent on soil type
  26. Lincoln-Peterson Model
    • Assumes closed population, equal probability of individuals being captured, and that marks are not lost/gained/overlooked.
    • Population estimate
  27. Schabel Estimation Method
    • Closed population, equal probability of capture, marks not lost/gained.
    • Population estimate.  Allows marking and recapturing over several occasions, not always separated by equal time intervals
  28. Cormack's Test
    Tests for trap happy/trap shy
  29. Jolly-Seber
    • Open population, equal catchability, equal survival, marks not lost/gained, instantaneous sampling (release made immediately after sampling)
    • Population estimate, survival rates (short term)
