Title: Explicit integrated modelling
for studying animal population dynamics
Abstract: Capture-recapture surveys are widely used to study survival rates and population trends in animal populations. They consist of a series
of occasions, on which animals are captured and released in the population. Individuals captured for the first time are marked with a unique identification number, while recaptured individuals have their identifier number recorded. Oftentimes, a single population
is studied using additional types of surveys, e.g. visual count surveys, carcass recoveries or telemetry surveys. The integration of all the data in a single statistical analysis is a very exciting mechanism to fully exploit the potential of the data. This
is typically achieved by approximating the full joint likelihood of the data as a product of likelihoods.
In this talk I will introduce a new Bayesian modelling approach which integrates capture-recapture data with other sources of data in a fully explicit manner. I will focus on the simplest case of integrating
capture-recapture data along with count data and compare the performance of the new approach with the usual approach (product of likelihoods) using both a simulation study and a real world application. If time permits I will present a more complex use of the
method which integrates capture-recapture data, dead recovery data and snorkel survey data to study the movement of Chinook salmon (Oncorhynchus tshawytscha) from the ocean to spawning grounds on the West Coast of Vancouver Island, Canada.
There will be tea and coffee after the seminar in the Mathematics Common Room (5212).
This seminar is a part of Maxwell Institute seminar series.
