Should we account for imperfect detection when evaluating patterns in fish abundance?

Our recent paper sheds light on the issue of imperfect detection when evaluating patterns in fish abundance. We synthesize the information from numerous studies to develop a realistic expectation of when and how the detection probability should vary when sampling fish. Our … Continue reading

Virtual ecologist module #3: occupancy model power analysis

The Virtual Ecologist refers to the practice of simulating complete experimental designs, that is, the ecological process, the observation process and the statistical analysis. This simulation tool can be used to evaluate trade-offs among experimental design components when design complexity prevents … Continue reading

Species richness estimators can give misleading results when determining patterns in biodiversity

Some years back I was challenged with the questions of how to track fish species richness through time in a selection of freshwater lakes in Florida. I first started experimenting with some of the simpler nonparametric species richness estimators as … Continue reading

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
