The FSU Mote Research Working Group

The Mote Research Working Group (RWG) provides a unique opportunity for the Eminent Scholar in Marine Biology, Visiting Scholars, and marine scientists and graduate students at Florida State University to develop and explore new, innovative, and topical areas in Marine Biology. Each year, the RWG brings together a small group of experts for approximately one week to integrate existing data and/or formulate new testable hypotheses and approaches for addressing issues important to conservation and ecology of marine systems. The group is housed together in an inspiring location to provide a close interactive environment conducive to deep, focused thinking and sudden insights and discoveries.

The 2017 Working Group - Mating Systems In The Sea

This Mote Research Working Group will bring together expertise on mating system evolution in marine organisms and plants in order to develop new ideas into a call to action. The degree of relatedness between mates has a profound influence on how genetic variation is distributed within and among populations and therefore on the ability for species to respond to environmental changes. A number of the selective forces that contribute to mating system evolution, including gamete limitation, inbreeding depression, and kin structure have been explored individually in marine invertebrates, but neither a synthesis of these concepts into a unified framework, nor a reconciliation with the theory derived for terrestrial plants has emerged.

The 2016 Working Group - Causes and consequences of metabolic scaling in clonal marine invertebrates.

Clonal marine invertebrates include sponges (multicellular organisms with no organs, but with specialized cells), colonial species consisting of multiple units or modules (e.g., corals, bryozoans, colonial ascidians), or species that produce mobile modules that are physiologically independent (hydroids, anemones). The units or modules include cells (sponges), polyps (cnidarians), or zooids (bryozoans, ascidians), and are genetically identical (though chimeras and colony fusion can occur in some species and modules sometimes show some degree of functional specialization). The size of the module, the degree of module integration, and the overall size and morphology of the organism vary dramatically within and between species from a range of phyla.

Key questions about clonal species addressed by the RWG include:

  1. In terms of metabolism, what is the appropriate measure of whole organism size for a clonal marine invertebrate (e.g., volume, tissue surface area, tissue mass, whole colony mass)? How and why does the appropriate measure of size differ between taxa?
  2. How and why does module size (e.g., cells, polyps, zooids) scale with whole colony size and growth form?
  3. How and why does whole colony size scale with metabolic rate?
  4. How does mechanistic knowledge of module integration alter expectations for how whole colony size influences the metabolic constraints of individual modules?
