Mark and recapture is a method commonly used in ecology to estimate an animal population's size where it is impractical to count every individual. [1] A portion of the population is captured, marked, and released.
At the individual level, genetic identification can enable estimation of population abundance and population increase rates within the framework of mark-recapture models. . The abundance of cryptic or elusive species that are difficult to monitor can be estimated by collecting non-invasive biological samples in the field (e.g. feathers, scat or fur) and using these to identify individuals ...
The Lincoln index is a statistical measure used in several fields to estimate the population size of an animal species. Described by Frederick Charles Lincoln in 1930, it is also sometimes known as the Lincoln-Petersen method after C.G. Johannes Petersen who was the first to use the related mark and recapture method.

In mark-and-recapture methodology, a sample is taken directly from the population, marked, and re-introduced into the population. At a later date, another sample is then taken from the population (re-capture), and the proportion of previously marked samples is used to estimate the actual population size.
Especially he was the first to use the Mark and recapture method which he used to estimate the size of a Plaice population. The Lincoln-Petersen method (also known as the Petersen-Lincoln index) is named after him and Frederick Charles Lincoln who first described the method in 1930.

Manhattan plot: Used to display data with a large number of data-points, many of non-zero amplitude, and with a distribution of higher-magnitude values. The plot is commonly used in genome-wide association studies (GWAS) to display ...
