11. Sightings -

Researchers often use a minimum of 11 sightings as a statistical baseline for various ecological analyses.

The number "11" often appears in time-series data reflecting population trends and seasonal migrations.

: Monitoring in the Sangti Valley recorded 11 sightings of these birds in the 2005–06 season, a figure that has since declined due to human activity and habitat disturbance. 11. Sightings

The phrase is frequently used in scientific literature and conservation reports to denote specific thresholds for identifying species distribution, social network patterns, or seasonal presence. Scientific Significance of the "11 Sightings" Threshold

: Marine biologists studying the Deraniyagala's beaked whale used a set of 11 photographed sightings to build a profile for identification, comparing morphology against genetically confirmed individuals. Conservation Case Studies Researchers often use a minimum of 11 sightings

: Social media and tourist reports are increasingly used to monitor elusive carnivores and marine life, where small clusters of sightings (such as the 11 sightings recorded for monk seals in Mykali ) help scientists assess the health of local populations.

: In studies conducted at Shark Bay , a threshold of 11 sightings was used to identify individuals (such as dolphins) consistent enough for inclusion in social network and genetic analysis. The phrase is frequently used in scientific literature

Modern data collection relies heavily on public participation to reach these critical numbers.
