Again, another opportunity. Sorry for any cross-posting!

Ella


 Loughborough University has a PhD studentship competition open, with a
closing date of 30 March, full details of which can be found here:
http://www.lboro.ac.uk/service/graduateschool/funding/GraduateSchooolStudentships.htm

In the Geography Department at Loughborough, we have funding for summer
2012 fieldwork at Tarfala, northern Sweden, on the topic below. We would be
very interested in hearing from anyone who would be interested in pursuing
PhD research in this topic, and who would like to apply to the studentship
competition noted above.

Clearly this opportunity would suit someone who is actually available for
fieldwork in summer 2012; please note that a studentship application would
be in competition with other topics across the university - although we
hope that the availability of fieldwork funds will make for a compelling
case.

Please contact Paul Wood ([log in to unmask]) or Richard Hodgkins (

HYDROECOlogical variability in ARCtic glacierized catchments: Tools for
Interpreting Change (HYDROECO-ARCTIC)

Current studies of glacierized catchment hydroecology are biased towards
mountainous, mid-latitude locations, though the characteristic features of
Arctic latitudes, such as physical remoteness, extensive permafrost and the
occurrence of the polar day and night, are likely to create distinctive
ecological responses. There is consequently a need for interdisciplinary
studies that link the particular hydrological characteristics of
high-latitude catchments occupied by glaciers with their aquatic ecology.
Hydroecological research from alpine catchments has indicated significant
variability in the composition of benthic stream communities in relation to
variability in runoff characteristics and habitat. However, comparable
evaluations for Arctic locations are currently very limited. To address
this shortfall, the following aims are proposed:
(1) Define and quantify water-source contributions and pathways for an
Arctic catchment exhibiting glacier retreat: Tarfala, northern Sweden;
(2) Test Brown et al.’s (2003) alpine stream habitat classification for the
Arctic location;
(3) Assess spatio-temporal variability in aquatic physical habitat, in
terms of runoff magnitude and variability, water temperature, total
dissolved solids, turbidity, channel stability;
(4) Assess spatio-temporal variability in benthic macroinvertebrate
community composition, diversity, life histories, species traits
and habitat utilization;
(5) Evaluate Milner and Petts’ (1994) influential, conceptual model of
benthic macroinvertebrate community structure for the Arctic catchment.
With the recent, unprecedented acceleration in atmospheric warming over the
Arctic, the need to address uncertainties in environmental change response
is urgent. A greater understanding of the resilience of hydroecological
communities, and of biotic interactions within them, to changes in runoff
sources, timing and magnitude, would increase our understanding of
community response, and indicate the ability of organisms to adapt to
environmental change. Our proposed Arctic-specific evaluation of
stream habitat classification and of the development of benthic
macroinvertebrate community structure will provide tools to interpret
and predict the response of aquatic ecology to changes in hydrological
regime forced by continued atmospheric warming.
