CRMRN seeking post-doctoral scholar

The Alaska Coastal Rainforest Center at the University of Alaska Southeast seeks a postdoctoral scholar to take the lead in creating and publishing terrestrial carbon stock assessments along the North Pacific coast, one of the most carbon-dense forested systems in the world, with a specific focus on linking model outputs to lateral carbon transport models to generate a true terrestrial to ocean perspective on C transport.  The position will be located in Juneau, Alaska, with opportunity to travel and work with team members at other institutions in the US and Canada as needed.

The position is a one-year term, benefit-eligible position with a chance for renewal.  All applicants must have a PhD in a relevant field (e.g., forest/ecosystem ecology, biogeochemistry, environmental science).  The ideal candidate will have a background and skills in landscape-scale forest ecosystems and carbon cycling, such as a background in forest soils or ecosystem-scale flux measurements.  Because the goals of the project are explicitly spatial, the candidate should also have experience using and manipulating geospatial and remotely sensed datasets, as well as basic proficiency in programming languages such as R or Python and geospatial software (e.g., ArcGIS or GRASS).

For more information, please contact Dr. Brian Buma (bbuma@alaska.edu). To apply, please visit http://careers.alaska.edu/cw/en-us/job/505697/nsf-post-doctoral-fellow.

Post-doctoral Fellow: Process-based modelling of responses of small streams to reach-scale and catchment-scale disturbance. University of British Columbia, Vancouver, Canada

Closing date for applications: 17th February 2017, but applications accepted after the deadline.

Start date: 1st May 2017 or soon thereafter

We are seeking a Post-Doctoral Fellow for a collaborative project between University of British Columbia, Swedish Agricultural University (Umeå, Sweden) and University of Oulu (Finland), to develop process-based models for interactions between small streams and surrounding forests, as well as catchment effects from forestry. The processes of interest include hydrology, geomorphology, chemistry & biology, although we appreciate that most candidates will not be expert in all fields.

The ideal candidate will have excellent quantitative skills in process modelling, and expertise with flowing-water ecosystems, especially their hydrology, geomorphology or biology. Ability to program in a language such as R or Matlab would be highly desired, as would experience with ecosystem model platforms and spatial statistics with GIS. The most qualified applicants will have relevant experience, expertise in biological and physical processes in streams, and a strong interest in stream and riparian systems and disturbance.

Evidence of successful participation in team projects would be helpful. Applicants must have completed and defended their Ph.D. by the start of the appointment. Previous peer-reviewed scientific publications are highly desirable. Interested applicants should submit the following:

 

  • Cover letter, C.V., and the names and contact information for three references
  • Unofficial transcripts
  • Examples of your published work

 

Funding is available for one year, with a second year for reappointment pending satisfactory performance.  Only those called for interviews will be contacted.

The position will mostly involve modelling work at the University of British Columbia, but also require international travel to meetings with partners. The position will involve limited field research in a number of locations in southern British Columbia. The Post-Doctoral Fellow will be based at the University of British Columbia under the supervision of John Richardson.

UBC hires on the basis of merit and is committed to employment equity. All qualified persons are encouraged to apply. However, Canadian citizens and permanent residents in Canada will be given priority. We especially welcome applications from members of visible minority groups, women, Aboriginal persons, persons with disabilities, persons of minority sexual orientations and gender identities, and others with the skills and knowledge to engage productively with diverse communities.

Longest running successional plot network in the world: All photos

The longest running ecological plot network in the world looking at succession (1916-present) is in Glacier Bay, and now all available photographs have been compiled.  They show a plant community evolving, from mostly bare rock to a variety of current states – spruce, alder, and willow, very different endpoints and something apparently unique to this portion of the bay.  For more information, higher resolution, and some data, see brianbuma.com/

New map of yellow-cedar decline published

A new map of both the range and decline of yellow-cedar has been published in Global Change Biology with help from researchers in Alaska, BC, and Washington.  The high resolution range map stretches from northern California to southcentral Alaska, from sea level in the north to treeline in the south.  The decline, now quantified at ~400,000 ha (about 7-8% of the total range area), covers southeast Alaska and central coastal BC, down to about 50 degrees north.  It is primarily located in areas where the mean winter temperature is between -2 and +2 degrees C, as anticipated.  The future climate of the region is expected to warm to that threshold by 2070 in most locations.  However, there are a few places above that threshold where cedar is apparently healthy, probably due to a lack of cold winters to trigger the decline when there is no snow on the ground like the outside of Vancouver Island.  How representative these sites are of the population at large needs to be further quantified.  Next steps include a predictive model of decline and comparison of the decline maps to other sources of mortality data.

Yellow-cedar, meet red cedar

It’s very wet on Prince of Wales Island.

Yellow-cedar, a prominent tree species along the coastal margin (ranging from California to Alaska) is dying, in some places rapidly.  About 8% of the current range is currently affected, and in places where the mortality hits, generally about 70% of the basal area dies.  Basal area is a measure of how much area the trunks (stems) cover near the ground. This mortality is directly related to a warming climate, as it is related to low snow coverage and subsequent root freezing in cold snaps. Continue reading “Yellow-cedar, meet red cedar”
