1. What roles did Aldo Leopold play in the history of -Promoted land ethic
wildlife management/ecology? -Deplored lack of connec-
tion between average per-
son and the outdoors
-1924: helped create Gila
National Forest- 1st pro-
tected wildlife area in the
U.S.
-1923: watershed hand-
book- water conservation
in the southwest- served
as a model for the creation
of the soil conservation act
(1936)
-Led the wilderness soci-
ety
-Key part to passing the
Wildlife Act of 1964
2. Be able to describe the main contributions of Rachel -Silent spring (1962)
Carson to wildlife conservation. -Exposed negative conse-
quences of pesticide use
-Sparked environmental
movement
3. What types of sampling issues (logistical challenges, -Individuals moving
methodological needs, etc.) were illustrated by our around
beach sampling (estimating population size of "horse- -Some grids had few to
shoe crabs") activity? none crabs while some
grids had a lot of crabs
which can alter the ap-
, Chamberlain College of Nursing
parent density and abun-
dance of the species
4. Why is random sampling important? It guarantees no bias by
giving all individuals an
equal chance to be sam-
pled
5. What is so challenging about random sampling? You could potentially miss
out on a particular group
in a sample or the loca-
tions chosen might have
individuals all clustered in
one spot, so the sampling
may poorly represent the
larger population
6. What is stratified sampling, and why is it used? -Split up area into differ-
ent strata; then randomly
select x number of grids
within each
-Ensures that sampling is
more extensive through-
out sampling frame (more
representative than sim-
ple random sampling)
7. What is a population index? An index of population
indicates relative size of
a population and shows
population trends (up,
down, stable) but does
not provide an actual esti-
, Chamberlain College of Nursing
mate of the number of an-
imals.
8. Why are population indices so commonly used in -Because it is much easier
wildlife management? to collect data for the cal-
culation of an index
-Instead of counting in-
dividuals, you can count
muskrat houses, scats,
nests, etc
9. For a population index to be useful in studying a pop- For a population index to
ulation what does it need to do? be useful to wildlife man-
agers or researchers, it
must (at a minimum) be a
variable that it highly cor-
related with total popula-
tion size
10. Lincoln-Peterson Method -simplest method
-two trapping sessions
-Session 1: all captured
individuals marked, re-
leased
-Session 2: individuals
counted, marks noted
(record total capture and
number of recaptures)
11. Schnabel Method -Multiple trapping ses-
sions
-All animals counted each
session, and marked if not
