Sample interview questions: Explain your knowledge of different sampling techniques used in wildlife research.
Sample answer:
1. Capture-Mark-Recapture (CMR)
-
Purpose: To estimate population size, survival rates, and movement patterns.
-
Method:
- Traps are set to capture animals.
- Captured animals are marked (e.g. with tags or dyes) and released.
- Traps are set again to recapture marked animals.
- The proportion of marked animals in the second sample is used to estimate the population size.
2. Radiotelemetry:
-
Purpose: To track the movements and behavior of individual animals.
-
Method:
- Animals are fitted with radio collars or tags that transmit signals.
- Receivers are used to track the movement of the animal.
3. Camera Trapping:
-
Purpose: To monitor wildlife populations and document species presence.
-
Method:
- Cameras are placed in strategic locations, often along trails or near water sources.
- The cameras are triggered by motion and take pictures of any animals that pass by.
4. Distance Sampling:
-
Purpose: To estimate the density of a population.
-
Method:
- A transect is established and observers record the distance to each animal seen a… Read full answer
