Test your knowledge on ecological sampling methods, biodiversity indices, and more with this comprehensive quiz.
#1
Which of the following is a primary goal of ecological sampling?
To completely map out all species in an area
To estimate the biodiversity of an area
To eliminate invasive species
To artificially increase the population of a species
#2
Which sampling method involves dividing the study area into smaller, manageable sections and sampling randomly within these sections?
Random sampling
Systematic sampling
Stratified sampling
Quadrat sampling
#3
What is the formula for calculating Simpson's Diversity Index?
D = N(N-1)/Σn(n-1)
D = 1 - Σ(n/N)^2
D = Σ(n/N)^2
D = ln(N)
#4

#5
What does the term 'beta diversity' refer to in ecology?
The diversity of species within a single habitat or ecosystem
The rate of species turnover between habitats or ecosystems
The diversity of species across multiple habitats or ecosystems
The diversity of species within a population
#6
Which biodiversity index considers both species richness and evenness?
Margalef's richness index
Simpson's Diversity Index
Shannon-Wiener index
Simpson's Evenness Index
#7
Which biodiversity index is sensitive to both the number of species and the abundance of each species?
Margalef's richness index
Shannon-Wiener index
Simpson's Diversity Index
Simpson's Evenness Index

They are used to estimate the number of species in an area.
They show the relationship between sample size and species richness.
They are only applicable to marine ecosystems.
They are used to measure the density of species in a given area.
#9
