:                      Marine Mammal Division

:      A one-year National Research Council Associateship
: (renewable to three years) is available in the Marine Mammal
: Molecular Genetics Laboratory of the Southwest Fishery Science
: Center located in La Jolla, California.  Ph.D. with experience
: and/or interest in population genetics or modelling is sought to
: formulate quantitative means for using genetic data to define
: biologically meaningful stock units on which to base conservation
: and management efforts for marine mammals.  Stocks, not species,
: are the units on which conservation and management efforts, by
: law, must be focussed, yet how to do this remains one of the most
: important questions in conservation biology today.   

:      In spite of rapid progress in the molecular arena,
: development of quantitative means for using the information
: gained in the laboratory to define biologically meaningful stock
: units has not been fully realized.  Methodologies using molecular
: data to estimate population-genetic parameters, molecular
: phylogenies, gene flow and dispersal distance, etc., are
: available, but there has been growing realization that this area
: is much more complex and pitfall-ridden than had been thought,
: especially when the methods are applied to incompletely isolated
: populations.  Nevertheless, the continuing rapid advances in
: molecular methods, the reality of laboratory automation, and the
: ability to measure genetic diversity directly from pooled samples
: will provide data of heretofore unavailable breadth and scope.  A
: concentrated research effort focusing directly on how to use
: these data to define stock units in potentially politically
: controversial situations is needed.

:      Envisioned, for example, is the development of an
: individual-based model of evolving and interchanging local
: populations, which could be stochastically sampled in order to
: test the utility of various analyses of population genetic
: structure for defining management stocks.  Such a model would
: also serve as a means of designing practical sampling programs
: for such purposes and, in the course of which, measures of the
: statistical power of the quantitative indices should be
: developed.  

:      NRC Associates receive a stipend from the National Research
: Council while carrying out his or her proposed research.  The
: current annual stipend for a Regular Associate (< 5yr from PhD)
: is $30,000 per year.  Suitable relocation reimbursement will be
: determined for an awardee, and funds are available for
: professional travel during tenure.  Applicants should direct
: initial inquires to Dr. Andrew Dizon (andy at or Dr.
: William Perrin, PO Box 271, SWFSC, La Jolla, CA, 92038.
