Methods of Plant Smapling Flashcards
What is the definition of random sampling in plant biodiversity techniques?
Sampling where locations are randomly selected using random numbers as coordinates.
What is one advantage of random sampling?
Reduces bias in selection.
What is a disadvantage of random sampling?
May not cover all areas and species with abundance.
What is opportunistic sampling?
A non-random sampling technique where samples are taken from areas that are easier to access.
What is a disadvantage of opportunistic sampling?
Can lead to biased results.
What is stratified sampling?
A non-random technique that divides a habitat into different strata and samples each area separately.
What is one advantage of stratified sampling?
Increases chances of capturing underrepresented species.
What is a disadvantage of stratified sampling?
Data may be skewed, leading to overestimates of biodiversity.
What are the two types of sampling mentioned?
- Random sampling
- Non-random sampling
What does systematic sampling involve?
Samples taken at fixed intervals across a habitat.
What is a disadvantage of systematic sampling?
May miss species that are not evenly distributed.
What is one method used to assess plant biodiversity?
Quadrat sampling.
What is the purpose of using quadrats in sampling?
To estimate species abundance and distribution.
True or False: Opportunistic sampling is quicker than random sampling.
True
What can systematic sampling show about a habitat?
How abiotic factors affect species distribution.
