What can we do with a single survey?

August 04, 2015 Talks poster single visit detect R

We presented a poster at the ICCB/ECCB 2015 congress in Montpellier, France, that summarized our research on single visit methodology.

We showed that if information on habitat covariates that affect occupancy/abundance and detection are collected, then one can estimate detection probability as well as occupancy/abundance parameters.

Check out the reprints and the poster made with Scribus:

Organizers wanted the poster sessions to be interactive. But posters are hung up much longer than the actual poster session. What can be done to make posters interactive in the absence of a presenter? This gave the idea to mimic a blog post, both in style and in structure. I added space for comments and created a mini poll, left out a marker on a string, and waited for the results.

Survey responses were mostly positive, which is good. But the best of all was a cute little girl who was thrilled at the notion of drawing onto the poster. Thanks for the feedback!

Fitting removal models with the detect R package

In a paper recently published in the Condor, titled Evaluating time-removal models for estimating availability of boreal birds during point-count surveys: sample size requirements and model complexity, we assessed different ways of controlling for point-count duration in bird counts using data from the Boreal Avian Modelling Project. As the title indicates, the paper describes a cost-benefit analysis to make recommendations about when to use different types of the removal model. The paper is open access, so feel free to read the whole paper here).
