The development of new monitoring techniques Flashcards
1
Q
What is a drone
A
- small or medium unmanned aerial vehicles - able to produce photographs and live images
2
Q
How are drones used in wildlife monitoring
A
- mapping habitats
- thermal imagery
- monitoring biodiversity
3
Q
Why would we choose to use drones rather than more traditional techniques
A
- quick results
- less invasive
- catch natural behaviour
4
Q
Are there any drawbacks to using drones
A
- limited battery
- quite loud
- expensive
5
Q
Examples of using drones
A
- rhino conservation - able to see the hot spots for rhino poaching
6
Q
What is a satellite
A
- an object which has been sent into space in order to collect information or to be part of a communications system
7
Q
How are satellites used in wildlife monitoring
A
- penguin huddles
- monitoring vegetation
8
Q
Why would we choose to use satellites rather than more traditional techniques
A
- can watch large areas and get the data quickly
9
Q
Are there any drawbacks to using satellites
A
- expensive
- cloud cover can hinder the use of satellite imagery
10
Q
Example of using satellites
A
- whale tracking
- it traces the movement of the whales when they are in the depths of the ocean
11
Q
How is eDNA used in wildlife monitoring and conservation
A
- you swab an area and the eDNA that is collected will show what species were there or are still there
- species leave DNA in skin cells, urine etc
12
Q
How is image recognition used in wildlife monitoring and conservation
A
- use camera traps with motion sensors
- it takes a picture every time something moves past it
13
Q
How is acoustic monitoring sonograms used in wildlife monitoring and conservation
A
- monitoring sounds animals make
- this allows for a picture to be built about their range
- also helps to know how many there are
