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

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

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

Approximating 80% statistical power with management triggers

Recently I have been involved with the evaluation of two monitoring program designs where the objective of the program is to detect when a metric has crossed a specific threshold that is used to trigger management.  For these programs the … Continue reading
