[ES_JOBS_NET] graduate position - experimental wetland inundation

[Helen Baulch]

*PhD (or MSc) research opportunity:*

Biological response to experimental wetland inundation



*The project: *Many large rivers in cold regions experience annual spring
and summer floods associated with the melting of snow and ice.  The
biological implications of these floods are poorly understood but could be
responsible for maintaining ecosystem integrity and viable fish and
wildlife populations.  Alterations to natural flow and flood regimes by the
construction of dams and levees and wetland drainage have placed these
habitats under threat.



We are seeking a qualified and motivated student to examine the timing and
magnitude of primary and secondary production in response to inundation in
a northern river ecosystem, the Saskatchewan River basin, Canada’s most
threatened river.  The student will work as part of large
inter-disciplinary team examining the role of shallow wetlands in driving
fish and wildlife production in large rivers.  This unique opportunity will
involve the delivery of water from the river into a previously dry spillway
channel by a hydropower production company (SaskPower).  This experimental
wetland will be used to understand if temporary habitats boost biological
production for the broader river ecosystem.  The candidate will test if
these temporary habitats are a net source or sink of carbon production and
if carbon produced in the system is transferred to emerging aquatic insects.



*Qualifications: *Applicants will have a Master’s degree in Biology,
Environmental Sciences, or equivalent and meet the requirements for
admission into the PhD program in the School of Environment and
Sustainability (www.usask.ca/sens). Prior experience with ecological field
work and a valid driver’s license are required.  Experience with
sensor-based measurements of ecosystem metabolism and secondary production
of benthic invertebrates, first-aid training, and proficiency in operating
watercraft would be considered assets.  Preference will be given to
applicants to the PhD program with a prior graduate degree, but exceptional
students entering a Master’s program will also be considered.



*Starting date: *Paid field work will commence in May with expected
enrolment in the graduate program beginning in September.
