This technique has long been at the forefront of quantitative ecology, epidemiology and the social sciences for estimating the size of populations that are difficult to count directly. By using ...

1. Mark-recapture methods are frequently used to estimate survival rates, which inform wildlife management policies. Mark-recapture models assume zero mortality of marked animals during the period of ...

(CN) – A new technique for estimating the populations of endangered and threatened species – involving the birdwatching public – could make conservation efforts more effective. The technique updates ...

An innovative new method of estimating the density of snake populations without employing the capture-mark-recapture technique has been created by a biologist. How can researchers determine the number ...

We used a mark-recapture method and model averaging to estimate apparent survival, recruitment and rate of population growth in a native freshwater mussel population at a site on the Cacapon River, ...

A new study has shown for the first time that acoustic monitoring can be used in place of photographs to generate abundance estimates of dolphin populations. An international team of scientists has ...
