Announcement of international PhD grant in Polar Sciences for vegetation and
permafrost studies in Antarctica
Duration: 3 years
PhD in Polar Sciences: the PhD is an international PhD, therefore not
Italian student are invited to participate to the public selection
The PhD activities will be developed within the project “Permafrost and
Climate Change in Antarctica: study and monitoring of Climate Change impacts
on permafrost and related terrestrial ecosystems”. This project is inserted
in an international framework and is linked to international and
multidisciplinary panels, such as GCOS (Global Climate Observing System) and
the SCAR project EBA (Evolution and Biodiversity in Antarctica) (formerly
RiSCC, Regional Sensitivity to Climate Change in antarctic terrestrial and
limnetic ecosystems), LGP (Latitudinal Gradient Project), CALM (Circumpolar
Active Layer Monitoring), ANTPAS (Antarctic and sub-Antarctic Permafrost,
Periglacial and Soil Environments) and TSP (Permafrost Observatory Project:
A Contribution to the Thermal State of Permafrost) and GTNet-P (Global
Terrestrial Network for Permafrost).
Work location: University of Ferrara, Italy and, partially, at Milano and
Varese University (Italy).
Tutor: Dr PhD Nicoletta Cannone (University of Ferrara)
Requirements: The candidates must provide a second level degree at least a 4
years degree, documented polar experience, specialization in Botany and
fluent English (the learning of elemental Italian could be useful) and are
invited to contact and send their curriculum vitae to Dr Nicoletta Cannone
to the e-mail address: nicoletta.cannone at unife.it
Economical information: The amount of the grant will be of 10561 EURO per
year. In addition, the grant will cover the travel expenses from Ferrara to
the research areas and return to Ferrara and all the authorised travel
expenses needed for the research activities. During the periods of field
activities in areas located south to latitude 60° S, there will be an
additional payment for all the period of permanence in Antarctica.
Topics and activities: The research activities will focus on the study and
the monitoring of the relationship between vegetation, permafrost and the
climatic change through a multidisciplinary approach along latitudinal and
climatic transects. The research will focus on two different biogeographic
areas of Antarctica, respectively, Continental Antarctica and Maritime
Antarctic and, for comparison, on the Svalbard Islands as template site for
the Northern Hemisphere.
One of the main research objectives will be to analyse the vegetation
changes (both at species and community level) of long-term monitoring plots
established across a latitudinal network at Victoria Land (Continental
Antarctica) in 2001-2003, and at King George Island (South Shetlands,
Maritime Antarctica) in 2000-2001.
Moreover, the monitoring network of Victoria Land will be implemented
including new inland sites and new sites at the latitudinal extremes of the
investigated gradient and with the elaboration of a phytosociological map of
the vegetation occurring at the CALM site of Boulderclay. In Maritime
Antarctica the network is still under construction and will be implemented
with the inclusion of new sites in Maritime Antarctica at Rothera and Signy
and with the elaboration of a phytosociological maps of the vegetation
occurring at the CALM sites of Signy and Rothera. At Ny-Ålesund will be
established new long-term monitoring plots, thus providing data for a
bipolar approach.
The impacts of climate change on ecosystem functioning will be assessed also
through analyses of CO2 fluxes in the network sites both in Continental and
Maritime Antartica through an Infrared Gas Analyser (IRGA).
In addition, analyses of intraspecific genetic variability and of the
secondary metabolites of some target lichens species will be carried out to
evaluate their relationships to latitudinal and environmental gradients.
The research results will allow the development of models to forecast future
scenarios within the framework of SCAR-EBA project.
The research activities will be carried out in the frame of the project
“Permafrost and climate change in Antarctica” (funded by PNRA, Progetto
Nazionale Ricerche in Antartide) and are included in the frame of
international and multidisciplinary panels, such as the SCAR project EBA
(Evolution and Biodiversity in Antarctica), LGP (Latitudinal Gradient
Project), GCOS (Global Climate Observing System), ANTPAS (Antarctic and
sub-Antarctic Permafrost, Periglacial and Soil Environments) and TSP
(Permafrost Observatory Project: A Contribution to the Thermal State of
Permafrost), CALM (Circumpolar Active Layer Monitoring) and GTNet-P (Global
Terrestrial Network for Permafrost).
Field Activities: the field activities will be two research campaigns in
Antarctica and one in the High Arctic.
