What it is Filled
The proportion of individuals or biomass in a community that belongs to each species, describing how common or rare species are relative to one another, typically showing a few abundant and many rare species, summarised by rank-abundance curves and models such as log-series, log-normal and neutral distributions; relative species abundance is a core descriptor of community structure in ecology and underlies diversity indices and conservation assessment.
Why it exists Filled
Let an agent explain relative species abundance and how it is measured and modelled, describe its patterns and their explanations with attribution, support calculating diversity indices, and support ecology learning.
Distinguishing features Filled
- Relative proportions
- Rank-abundance curves
- Models of distribution
- Basis of diversity indices
What robots and AI may and may not do Filled
Must not
- Present relative abundance as absolute population size.
- Overinterpret a model fit as proof of a mechanism.
- Ignore sampling bias in survey data.
- Publish locations of rare species in ways that expose them to collectors.
Only with a human decision
- Using abundance data in conservation or land-use decisions.
May
- Explain relative species abundance and rank-abundance curves.
- Compute relative abundance from survey data, stating the sampling method.
- Describe models such as log-series and neutral theory with attribution.
Moral aspects Filled
- Rare species can be overlooked by misused statistics.
- Publishing locations of rare species can harm them.
Who is affected
- Rare species
