Cryptic species or deep spatial structure?

Better inform your taxonomic changes.

Test if your species delimitation is robust to spatial sampling.


Decrypt is a tool allowing to shed light on systems where cryptic diversity and isolation by distance are two competing hypothesis. Decrypt can help understanding if the genetic structure detected under the MultiSpecies Coalescent (MSC) could possibly be explained by an intra-species spatial structure scenario.

It can be seen as a way to automate MSC robustness analyses for different realistic demographic histories and spatial sampling schemes.

The Decrypt C++ demogenetic simulation core has been developed using the Quetzal library. It generates a spatially explicit demographic history incorporating environmental heterogeneity. At sampling time, it simulates gene trees under different sampling schemes. Then, sequences are simulated along the gene trees, and BPP is run for species delimitation.
