Q

Pre-baiting

A

acclimate animals to the trap overtime. Place a trigger that causes door to close on one end of the trap.

For animals that scurry under leaf litter

Hole in the ground that causes the animal to fall in and not get out.

16
Q

Bait marking

A

Animal ingests plastic pellets through bait and the pellets can be found in the feces

17
Q

Chelating agents

A

Used in bait markings and can show up in the bones of owl vomit

18
Q

Radio telemetry

A

Collar or implanted in skin

19
Q

Rules of radio telemetry

A

Cannot be more than 10-13% of animal’s max body weight.

Cannot interfere with animal’s behavior

20
Q

Observational techniques

A 
Focal animal study
Scan sampling
Instantaneous sampling
All occurrence sampling
Experimental observation
Ad lib sampling
21
Q

Focal animal sampling

A

only pay attention to one animal out of a group of them

22
Q

Scan sampling

A

look at what behaviors are engaged by the group

23
Q

Instantaneous sampling

A

Monitoring one individual to see their behaviors at certain times.
Tells you how long they persist in that behavior.

24
Q

All occurrence sampling

A

Monitoring a specific behavior and what percentage of the population is engaged in that behavior

25
Q

Experimental observation

A

manipulate variables to see what the population does

26
Q

ad lib sampling

A

monitoring all the individuals

27
Q

What can we learn through field methods?

A

Population density
Home range size
Habitat use
Diversity

28
Q

Determining population density through removal methods

A

Hayne method and Moran-Zippin method

29
Q

Haybe Method

A

Removal method to calculate population density.
Number of individuals from each collection plotted against previous number captured.
The more trapping that occurs removed more individuals from the population.

30
Q

Moran-Zippin Method

A

Removal method to determine population density.
N=(x^2)/(x-y)
x=# removed 1st time
y=# removed 2nd time

31
Q

Determining population density through live trapping

A

Lincoln-Peterson Index
Jolly estimate
MNKA

32
Q

Lincoln Peterson Index

A

Live trapping method to determine population density
Assumes population is stable, all of the individuals have an equal chance at being captures, mark doesn’t affect behavior, mark is constant.
N=MC/R
M=#captured, marked, and released first time
C=#captured 2nd time
R=#captured 2nd time that were marked from 1st time

33
Q

Jolly estimate

A

live trapping method to determine population density.
Allows for unstable population.
Software.

34
Q

MNKA

A

Minimum number known alive. Live trapping method to determine population density.
Underrepresented the size of the population.
Animal caught in a previous attempt is not caught in current attempt is still alive.
Preferred method.

35
Q

Diversity Indices

A

Species richness

Species evenness

36
Q

Minimum Convex Polygon

A

Home range estimation. The smallest polygon that encloses all of the capture points.
