what is diversity
the comparison of the variety of species in an area measure of difference among or btwn two or more entities measured in richness and eveness
How is diversity measured
It is a tool to measure difference in a community measured in evenness and richness
can you generate a usable def of diversity
Measure of difference or uniqueness within a community has many diff scales
what is diff between alpha, beta and gamma diversity
alpha- small area, nums of types of species beta - compare 2 area, num of speci unique to each eocosys gamma- total num of species in large region
richness vs evenness in terms of diversity
richness - the amt of diff types of species evenness - the amount of each species
what is bio indicator species what makes a good one
One that replicates fast and is sensitive to environmental conditions. easy to find shouldn’t migrate bc then we can’t see it change ex hydra, freshwater shimp -good rat tailed maggot - bad
how is diverstiy linked to bio org or complexity of life
through the different interactions of species. The more diversity there is the more complex it is. its harder to organize when theres lots of diff species/variation
simpson vs shannon diversity index
simpson - accounts for ruchness and evenness and the prob of 2 samples being from diff species Shannon-just richness and evenness, has a log
What do high, low values of simpson’s index mean
high - (high richness, high even) healthy, diverse, niches filled, low competition low - low richness, even, few potential niches, only few species thrive
