Research Fellow in spatial
ecological analysis and modelling
46 month postdoctoral
position (or may be split into 2 shorter posts if desired)
We are looking to recruit a
dynamic Early Career Researcher with a proven track record in ecological theory,
spatial mathematical or statistical modelling and/or software development to
address a number of exciting projects funded by 3 EU projects (EU-BON, SCALES
and ExpeER):
Developing spatial niche models (EU-BON, SCALES). Niche models are widely used to predict
species distributions and to forecast responses to future environmental
change. However, classical bioclimatic niche
models have been criticised for ignoring the spatial structure of populations,
greatly reducing their predictive power.
Conversely, spatial downscaling approaches rely exclusively on spatial
patterning to infer fine scale occupancy, but are insensitive to environmental
predictors of where such populations should be found. The goal here is to develop a hybrid
approach, one that takes advantage of both spatial and environmental pattern
information. These approaches will be
tested and applied to high-quality biodiversity datasets.
Developing up-scaling and down-scaling analytical tools (EU-BON, SCALES, ExpeER).
Biodiversity, abundance and function are spatially complex, multi-scaled and
often non-additive. Various techniques
have been developed for inferring coarse scale biodiversity from sets of local
samples (biodiversity up-scaling) and conversely to infer fine scale occupancy
from coarser scale distributional data (population down-scaling). We hope to further develop these tools, e.g.
to allow up-scaling in the absence of count data, using information on spatial
turnover patterns. We also need to
develop software tools or analytic libraries and appropriate documentation, to
make these approaches more widely available to non-specialist researchers and
conservation analysts. We will also test
for efficient sampling designs to be used in applications of these approaches
to population and biodiversity monitoring.
Implementing improved remote sensing vegetation models (EU-BON). Remotely sensed images are typically
classified on the basis of spectral reflectance data. The spatial scales of ancillary variables
typically receive little attention in the classifications of vegetation from
remotely sensed images; however recent research in our group has shown that
incorporating widely available environmental datasets (e.g. DEM, soils) at
local and neighbourhood scales has the potential to inform and greatly improve
such classifications, allowing much finer vegetation differentiation and higher
accuracy than would otherwise be possible.
We will further develop these methods to incorporate information about
temporal variation in reflectance and in vegetation, and develop application
software to make them more widely available.
These three goals are linked; the vegetation modelling involves a
form of the spatial niche modelling, and the resulting vegetation maps could
serve as habitat variables for modelling animal distributions. Moreover, both involve explicit scaling
approaches, tied to the downscaling methods.
The Research Fellow will join a
large and varied team of academics, postdoctoral researchers and postgraduate
students from both the Kunin and Benton labs, and the wider Leeds ecology and
evolution research group. They will also
have the opportunity to form collaborations with a wide circle of researchers
across Europe and beyond, and to participate in the three project teams.
Application deadline: 14 March 2013. For information contact Bill Kunin: w.e.kunin@leeds.ac.uk For further details and application materials: http://jobs.leeds.ac.uk, Reference: FBSBY0002
