Mark Capture-Recapture Method
Mark Capture-Recapture Method
Mark and
recapture is a method commonly used in ecology
to estimate an animal population's size. A portion of the population is captured,
marked, and released. Later, another portion is captured and the number of
marked individuals within the sample is counted. Since the number of marked
individuals within the second sample should be proportional to the number of
marked individuals in the whole population, an estimate of the total population
size can be obtained by dividing the number of marked individuals by the
proportion of marked individuals in the second sample. The method is most
useful when it is not practical to count all the individuals in the population.
It is
assumed that all individuals have the same probability of being captured in the
second sample, regardless of whether they were previously captured in the first
sample (with only two samples, this assumption cannot be tested directly). This
implies that, in the second sample, the proportion of marked individuals that
are caught ( k/K)
should equal the proportion of the total population that is marked ( n/N). For
example, if half of the marked individuals were recaptured, it would be assumed
that half of the total population was included in the second sample.
In
symbols,
k/K = n/N
the
formula used for the Lincoln–Petersen method.
N = Number of animals in the population
n = Number of animals marked on the first visit
K = Number of animals captured on the second visit
k = Number of recaptured animals that were marked
Ada contoh perhitunganya lebih bagus
BalasHapusIt's already good. Apalagi sudah ditambah gambah yg mendukung. Mungkin suggestionnya sama, yaitu diberi contoh permasalahannya dan perhitungannya. Semangaat :)
BalasHapusSebenarnya penanda seperti apa saja yang bisa digunakan dalam metode ini ? tali, cat, atau apa kak ?
BalasHapussudah baik penulisannya akan tetapi sumber gambarnya tolong dicantumkan ya.. sama beri contoh penelitian yang pernah dilakukan berikut perhitungannya yang dikaitkan dengan gambar contoh.
