Table 1 Biodiversity metrics used to characterise phytoplankton community structure and its explanation. We estimated two aspects of biodiversity: species richness and effective number of species (ENS).
Scale | Community structure metric | Definition |
|---|---|---|
Question 1 | ||
Station | γ species richness | Total number of species in all monthly samples at a given station rarefied by the number of monthly samples |
γ ENS | Total ENS of all monthly samples at a given station rarefied by the number of monthly samples | |
Mean cell abundance | Mean total cell abundance per station across all monthly samples | |
Mean α species richness | Mean number of species per station rarefied by number of individuals across all monthly samples | |
Mean α ENS | Mean ENS per station rarefied by number of individuals across all monthly samples | |
Question 2 | ||
Monthly sample | Cell abundance | Total cell number in a monthly sample from a given station |
α species richness | Number of species in a monthly sample from a given station rarefied by the number of individuals in the sample | |
α ENS | ENS of a monthly sample from a given station rarefied by the number of individuals in the sample | |
