[Ocees] Fwd: Speciation-based Delimitation Workshop, March 13, 2020

Thu Feb 6 13:42:06 EST 2020

Hi all,

If you are interested in using molecular methods to delimit species or like
to get a better understanding of modern phylogenetic analyses in general,
this is a great opportunity:

*Speciation-based Delimitation Workshop, March 13, 2020*

*University of Michigan, Ann Arbor, MI*

https://sites.lsa.umich.edu/species

A workshop on species delimitation will be held at the University of
Michigan, Ann Arbor, MI on *March 13, 2020*; the workshop is free but
limited to 65 participants, and participants must apply to attend, with
review of applications beginning Feb. 18. Note that participants are also
encouraged to also consider (and register) for the 16th Annual Early Career
Scientists Symposium “Natural History Collections: Drivers of Innovation
<https://sites.lsa.umich.edu/ecss/>” that will be held on March 14-15.

Note that through the generous support of the National Science Foundation
(DEB 16-55607) we will be offering travel scholarship to increase the
representation from interested participants who otherwise would not be able
to attend. Priority will be given to graduate students and postdocs. Send a
brief description of fit of the workshop and scholarship need (no more than
150 words) by Feb. 18.

Application for the workshop (and travel scholarships) should be completed
via the registration tab on the website. Please address questions to L.
Lacey Knowles (knowlesl at umich.edu) and see you in March!

Summary of Workshop:

The resolution in genomic data makes it possible to not only detect
divergent lineages, but also local population structure within them. Yet,
these conflated boundaries have received little attention from those
developing genetic-based species delimitation methods, potentially leading
to mass over-splitting as genomic data become more widely employed. These
challenges have profound implications for not only understanding the
generation and dynamics of biodiversity, but also for conserving this
diversity.

In this workshop, we will cover the foundations upon which genetic-based
inference of species boundaries are built. In particular, we will review
the history that lead to a reliance on the multispecies coalescent (MSC) as
the primary model for species delimitation. Despite the appeal of
genome-based species discovery, we will explain how misidentification of
population structure as putative species is an emerging key issue for
applications of the MSC for species delimitation, as well as the
implications of divergence of gene flow for identifying species boundaries.

We will then present two recently developed approaches to address the
misidentifications of species that occurs from confounding the structure
within species with the divergence that accumulates between species. One
approach, implemented in the program DELINEATE
<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fjeetsukumaran.github.io%2Fdelineate%2F%23requirements&data=02%7C01%7C%7Cf6cf0dd850804f0e4f0508d7ab344bc0%7Cf3308007477c4a70888934611817c55a%7C0%7C0%7C637166113401641115&sdata=CTFgfseNDWub%2BWBmtqhoyGB7SenKgou8KUqOCq2BqGU%3D&reserved=0>,
takes a phylogenetic lineage-based perspective to delimit species where for
the first time speciation is modeled as an extended process in the context
of species delimitation analyses, as opposed to being treated as an
instantaneous event. The other approach, implemented in the program DECRYPT
<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbecheler.github.io%2Fpages%2Fapplications.html&data=02%7C01%7C%7Cf6cf0dd850804f0e4f0508d7ab344bc0%7Cf3308007477c4a70888934611817c55a%7C0%7C0%7C637166113401641115&sdata=4dzso1%2BjsHizFO2zKhij0lFEoIJgRTtQ6ASQAOZ3rLA%3D&reserved=0>,
employs a spatially explicit coalescent model to characterize the geography
of divergence to test competing hypotheses regarding the detection of
cryptic diversity. Participants in the workshop will also receive hands-on
training with both programs, completing a series of computer demonstrations
and exercises.

These newly developed method should reduce the errors with genome-based
species delimitation, while also providing a framework for gaining insights
about the speciation process itself. Note the methods and associated
documentation  are freely available as the software packages DELINEATE
