They are referred to as natural history . in this book to distinguish them from data obtained from the wild.

Census Analysisy not cover both sexes and/or all age groups. Census of sex and age groups relies on characteristics that can be observed under field conditions. These limitations do not apply to studbook census which is based on data from identifiable individuals. Timing of this virtual census is not bound by fiel繁忙 发表于 2025-3-22 11:00:28
Births, Deaths and Migrationn census counts. Such data can be difficult to obtain for wild populations, but are relatively easy to obtain from studbooks. Crude birth rates that are estimated from birth and census counts provide an idea about the reproductive potential of the population. This measure can be refined, for example夸张 发表于 2025-3-22 13:28:14

Age, Mortality and Fecundityom following individuals born in the same season (cohort) until all have died. Since studbooks on endangered species are relatively small, virtual cohorts (individuals born over a period of years) are used. Age classes usually have a width of 1 year, but this can be adapted to the biology of a specipericardium 发表于 2025-3-22 23:27:11
