True
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

True or false, a bal-chatri trap can be used to capture ring-necked pheasants
False, used on raptors
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
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
True
True or false, harvested muskrats can be aged by examining the molt pattern on the inside of the pelt
True
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
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
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
False
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
False
True or false, sand shinnery oak is a fire intolerant species that cannot resprout following a fire
False
The distribution of sand shinnery oak is highly dependent on soil type
True
Lincoln-Peterson Model
Assumes closed population, equal probability of individuals being captured, and that marks are not lost/gained/overlooked.
Population estimate
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
Cormack's Test
Tests for trap happy/trap shy
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)
___ is an example of a permanent mark
A.
____ can be used to determine the density of benthic macroinverts
D.
_____ approves which drugs may be used on wildlife species
B.
___ is an example of a temporary marker
A.
An ideal drug for immobilizing large mammals should...
have a high therapeutic index, be avaiable in high concentrations, and have a short induction time
Which of these is not true about the North America BBS? a. It may be biased toward ssp that prefer edge habitat b. All ssp have equal detection probabilities c. Productivity cannot be determined from the survey d. it is an index
B
___ can be used to to measure population density. a. Mourning dove call-count survey
b. Data from the Harvest Information Program
c. Scent post survey
d. Spot-mapping method
D
If some animals become trap happy, the Lincoln-Petersen estimate will be...
too low
Which of these techniques cannot be used for aging waterfowl? a. Measure depth of bursa of fabricus b. Examine tail feathers for notches or attached down plumes c. Examine the shape of the wing coverts d. Examine the molt sequence of the primaries and measure their length.
D
Rabbits can be aged by...
a. counting cementum annuli
b. weighing dried eye lens
c. measuring baculum
d. examining the molt pattern on the inside of the pelt
B
(A is for bears, C is for species ID, D is for muskrats)
A(n)____provides an index of invertebrate abundances.
a. core sampler
b. artificial substrate
c. water column sampler
d. pitfall trap
D (a, b, and c have specific volume and therefore produce densities)
The appropriate concentration of ethyl alcohol for preserving aquatic invertebrates is___
95%
The best trap placement method for determining home ranges of small mammals is the _____ method
grid
The best trap placement method for conducting basic surveys of small mammals is the ______ method
transect
Before conducting a study that requires marking and handling animals, researchers affiliated with universities must have approval from ____
IACUC
When using Telazol for immobilization, researchers much take precautions such as __________ to protect the immobilized animal.
applying bland ointment to eyes and covering eyes
When darting an animal with a rifle, you should always aim for the _____ or ______ and avoid the _____, ______, and _____
rump or shoulder
the head, spine, and fatty areas
To calculate drug dosages, researchers must know 3 variables:
1) Recommended dosage
2) Animal's weight
3) Concentration of drug being used
Two problems with using scent posts are:
1) Certain individuals may frequent the scent posts disproportionately
2) The scent may actually act as a repellent
To age black bears, researches must remove the ____ which will be cross-sectioned so that they can count the ____
first premolar, cementum annuli
Two problems with using pitfall traps to collect terrestrial invertebrates:
1) They capture primarily active taxa (like Coleoptera)
2) The larger inverts might consume the smaller ones in the trap
List two ways that researchers who are mist-netting can increase their capture success:
1) Bait the area
2) Play song/call recordings
