When studying evolution, DNA is especially important in its application to identifying and separating organisms into species. However, DNA is a fragile molecule, and it degrades over time. For most fossil species, there is essentially no hope of ever acquiring DNA from their fossils, so answers to questions about their appearance, physiology, population structure, and more may never be fully answerable. For more recently extinct species, scientists have, and continue to, extract ancient DNA(aDNA) which they use to reconstruct the genome of long-gone ancestors and relatives.  4, record 1, English, - ancient%20deoxyribonucleic%20acid

The identification of stock structure is a necessary step for the effective management of multistock fisheries. As stocks are reproductively isolated from other members of the population, disregard of individual stock dynamics may alter genetic diversity of a population if one or more stocks are lost due to overexploitation or other causes... The knowledge of individual stock dynamics allows managers to assess fish population stability and set sustainable harvest limits. Monitoring inidividual stock dynamics within a population provides the opportunity to assess differential survival and contribution to the fishery. Once stock structure is uncovered, patterns in stock contribution can be managed by setting up measures to enhance or sustain stocks when annual production is lower than desired.  2, record 7, English, - multistock%20fishery

In order to model the progress of an epidemic in a large population, the population diversity must be reduced to a few key characteristics which are relevant to the infection under consideration. For example, for most common childhood diseases that confer long-lasting immunity, it makes sense to divide the population into those who are susceptible to the disease, those who are infected and those who have recovered and are immune. These subdivisions of the population are called compartments ... The SIR model labels these three compartments S = number susceptible, I =number infectious, and R =number recovered (immune).

[The Kermack-McKendrick model] was proposed to explain the rapid rise and fall in the number of infected patients observed in epidemics such as the plague(London 1665-1666, Bombay 1906) and cholera(London 1865). It assumes that the population size is fixed(i. e., no births, deaths due to disease, or deaths by natural causes), incubation period of the infectious agent is instantaneous, and duration of infectivity is same as length of the disease. It also assumes a completely homogeneous population with no age, spatial, or social structure.  3, record 16, English, - susceptible%2Dinfected%2Drecovered%20model

Analysis of Molecular Variance(AMOVA) is a method for studying molecular variation within a species. Electrophoresis, one of the most widely used methods for studying the structure of DNA, produces data of the form of 0s and 1s where 1 denotes the presence of a band and zero its absence, e. g. Sample Band A 0101... B 1000... C 0110... AMOVA works on such data to create a distance matrix between samples in order to measure the genetic structure of a population.
