Virtual ecologist module #2: occupancy model design trade-offs

The Virtual Ecologist method is a form of stochastic simulation where the process of collecting, analyzing, and interpreting data are simulated. This post is the second module of the Virtual Ecologist blog series. The first module was an introduction to using … Continue reading

Emerging methods for multi-model inference in ecology: inference based on parameter inclusion probabilities

A procedure for model selection has been recently showing up in the ecological literature that seems to have followed the increasing use of Bayesian hierarchical models. I was first introduced to the procedure by the book, “Hierarchical modeling and inference … Continue reading

Virtual ecologist approach: using simulations to evaluate experimental designs

This blog is the first in a series of modules that I will present on using simulations to evaluate experimental designs. The series will mostly consist of fairly simple simulations that I have built over the last decade to answer … Continue reading

Estimating the uncertainty in exploitation rates using parametric bootstrapping

Recently I taught a class on estimating fisheries exploitation rates with tagging studies.  A common study design to estimate exploitation rates is to release tagged fish into the system and allow anglers to return the tags when they harvest a … Continue reading

Using movement information to approximate population closure for mark-recapture sampling designs:

Abundance of animals in an area (i.e. density) is one of the most basic population parameters desired in applied ecology. Many methods have been developed to estimate abundance within an area such as mark-recapture; however, it is often unclear the … Continue reading
