Species composition
Only recordings with a species-level result are counted.
Noise/no-ID/unidentified recordings are excluded, so this doesn't sum to the total recordings tile above.
Rarest species
{% for entry in rarest.entries %} {% else %} {% endfor %}
{{ entry.taxon.scientific_name }}{{ entry.count }}
No species detected yet.
Rarest unmapped codes
{% for entry in rarest_codes.entries %} {% else %} {% endfor %}
{{ entry.code }}{{ entry.count }}
No unmapped codes.
Sites

No sites yet.
Ranked by Chao1 estimated true richness.
Estimates how many species likely occur at each site in total, including ones not yet detected -- doesn't always match the "Most species-rich sites" order, since a site with fewer observed species but more singleton/doubleton detections can rank higher here. See "Least-sampled sites" for how much to trust the observed counts behind the estimate.
Most diverse sites (Shannon H)
{% for entry in diverse_sites %} {% else %} {% endfor %}

Least-sampled sites
{% for entry in least_sampled_sites %} {% else %} {% endfor %}
{{ entry.site.name or "Site #" ~ entry.site.id }}{{ "%.0f"|format(entry.sample_coverage * 100) }}% coverage
No sites yet.
Lowest estimated sample coverage first -- where the observed species counts are least likely to be complete.
Coverage estimates the fraction of each site's true species composition already represented in its recordings (Good-Turing estimator); a low value means more undetected species likely remain.
