Capture-recapture sampling is a method used in ecology and wildlife management to estimate the population size of a species in a given area. The process involves capturing a number of individuals, marking them, and then releasing them back into the environment. After some time, a second sample is captured, and the number of marked individuals within this sample is recorded. By applying statistical methods to the captured data, researchers can estimate the total population size based on the proportion of marked to unmarked individuals.
by using the capture-recapture method which gives you the total size of organisms in a population.
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
Through mark-and-recapture projects, direct observations, or targeted sampling, ecologists are able to determine the population of a particular species. This process is a scientific estimation of the population.
Nyquist sampling refers to the principle that to accurately capture a continuous signal, it must be sampled at least twice the highest frequency present in that signal. This minimum sampling rate is known as the Nyquist rate. If the sampling rate is lower than this threshold, it can lead to aliasing, where higher frequency components are misrepresented as lower frequencies, distorting the signal. This concept is crucial in fields like digital signal processing and telecommunications.
Sampling of a signal is essential because it allows continuous signals to be converted into a discrete form that can be analyzed and processed by digital systems. By sampling, we can capture and represent the important features of the signal while reducing the amount of data needed for storage and transmission. This process is fundamental in various applications, such as digital audio, video processing, and telecommunications, where efficient data handling is crucial. Proper sampling ensures that the original signal can be accurately reconstructed later, adhering to the Nyquist-Shannon sampling theorem.

It's called "Reconquista". Capture of Aztec empire was conquista, so from this we have "conquistadors".
Ecologists can estimate population size through methods such as mark-recapture, distance sampling, and census surveys. Mark-recapture involves capturing and marking individuals, releasing them, and then recapturing a sample to estimate total population size. Distance sampling involves estimating population size by observing and recording the distances to individuals from a specific vantage point. Census surveys involve conducting a thorough count of all individuals in a specific area.

leafy seadragons only live in south australia and the population counted with the capture/ recapture method is 1,527,400
The assumptions of the mark-recapture method include: 1) The population is closed (no immigration, emigration, or deaths) during the study period, 2) Marks do not affect the probability of capture, and 3) Marks are not lost or overlooked between captures.
Census taking for sea horses is an impossible task. The best that you can hope for is a capture-recapture exercise.

Recapture of Angola happened in 1648.
The Third Crusade's resulted in a failure to recapture Jerusalem. Saladin still had control, but there was a treaty made between Saladin with Richard the Lionheart for anyone to be allowed to visit the holy land of Jerusalem.It resulted in the capture of the cities of Acre and Jaffa. The crusaders however failed to recapture Jerusalem. Saladin was forced to sign a treaty which guaranteed safe passage to Jerusalem for unarmed traders and pilgrims.
Recapture of Recife happened in 1652-05.
