About the Project

The waters around the Falkland Islands in the South Atlantic are nutrient rich and highly productive, with an oceanography defined by a mix of the cold waters from the Antarctic Circumpolar Current and the southward flowing Brazil Current. This high productivity supports several commercially important fisheries species as well as globally important marine mammal and seabird populations including sea lions, fur seals, baleen and toothed whales, albatross and penguin. Whilst some research has been conducted on how phytoplankton and zooplankton underpin the foodwebs in offshore waters, much less is known about the role of zooplankton in the Falkland Islands nearshore environment and how this operates as a nursery for commercial fisheries, predators and as trophic bridges to the offshore shelf ecosystem.

This outstanding PhD opportunity will support the recently funded Darwin Plus project examining “Climate change resilience in Falkland Islands fisheries and marine ecosystems” to identify key species in the Falkland Islands ecosystem, understand the linkages between inshore and offshore environments and produce ecosystem models that describe trophic interactions.

The studentship will combine marine ecology, population modelling and molecular techniques to

  1. Create a temporal and spatial atlas of zooplankton, ichthyoplankton and squid paralarval communities in the coastal waters of East Falkland.
  2. Elucidate the population dynamics of keystone crustacean species from pelagic life history stages to settlement and reproduction.
  3. Quantify the role of the Falkland Islands inshore environment as nurseries for commercial squid and fish.
  4. Quantify the role of the Falkland Islands inshore environment as trophic bridges to the shelf ecosystem.

The project will provide outstanding opportunities for fieldwork in the Falkland Islands (up to six months per year) supported by the South Atlantic Environmental Research Institute (SAERI), coupled with extensive training in the use of DNA barcoding and molecular markers for species identification and quantitative skills training and modelling. The project also involves considerable engagement with end-user and stake-holder groups with opportunities for translating the research into applied impact by influencing policy and practice.

Informal enquiries are encouraged. Please contact Prof. Stuart Piertney ([Email Address Removed]) for further information.

Essential background of student:

We welcome UK resident applications from exceptional candidates with an excellent academic record (at least a 2:1 Honour’s degree or international equivalent) in marine biology or zoology. Candidates should preferably have a Masters-level degree with Merit / Distinction.

A demonstrable track record of effective academic writing, conducting systematic literature reviews and quantitative data analysis is required. The candidates should be able to work remotely and independently as well as in a team, collaborate with colleagues and have excellent communication skills.

Funding Notes

This is a 36-month full time studentship starting in September 2022. The student will be registered at the University of Aberdeen, and the project will work in conjunction with the South Atlantic Environmental Research Institute (SAERI) based in the Falkland Islands. The project is directly funded by industry in support of the Darwin Plus grant “DPLUS148: Climate change resilience in Falkland Islands fisheries and marine ecosystems”. Funding includes home rate tuition fees (this includes EU nationals that hold UK settled or pre-settled status) and a stipend at the UKRI rate.
