Biodiversity, Evolution and Adaptation team
Our ambition
Is to understand how past, present and future environmental change has and will affect polar biodiversity both on land and in the ocean, and how life adapts to extreme polar conditions. Our research outcomes will provide deep insight into the impact of environmental change on the natural world, make a strong contribution to future conservation measures, and generate new and innovative areas of research that have potential societal benefits.
Our team has two research groups, Biodiversity and Adaptations. The Biodiversity group focuses its investigations on mapping species distributions, how they relate to current and past environments and how this information can be used to predict future distributions under environmental change. The Adaptations group investigates adaptations to extreme polar conditions, from the molecular level through physiology to ecology and, using experimental approaches, how these may affect species abilities to adapt under future change scenarios. Both groups work together towards the same aim: to develop a holistic picture of future patterns of biodiversity in a changing world.
Team priorities
Science
Biodiversity
- Patterns in biodiversity. Revealing the distribution of life in Polar Regions, from microscopic to global scales, to discover the critical environmental and biological drivers that shaped those patterns.
- Responses to historical and environmental change. Understanding current distributions of animals, plants and microbes can help us to constrain models of past environmental conditions. Studying how life at the poles has survived extreme environmental change in the past will help us to predict how it will react to future changes.
- Species and ecosystem functions and interactions in Polar Regions. This is mainly a terrestrial project that manipulates and models the network of interactions between soil microrganisms to understand how polar food webs work.
- Assessing human impacts. Human interactions with the biodiversity of the Polar Regions have the potential for serious negative impacts including pollution, habitat destruction, invasive species and over-exploitation. Surveying, monitoring and assessing key or vulnerable species and habitats allows us to inform policy makers responsible for resource management and environmental protection.
Adaptations
- Impacts of life in the cold. To understand how life has adapted to extreme Polar conditions we study the similarities and differences between species living at the Poles and those at lower latitudes from genetic, cellular and ecological perspectives.
- Species resilience to environmental change. Discovering how organisms react and respond to changing environmental conditions, and how their polar adaptations could be an advantage or disadvantage in a warming world.
- Calcification processes. Understanding how skeletons, especially shells, are produced by marine species (polar and European), and how this impacts their abilities to adapt under future climate change, informs how this knowledge can be used for societal gain for instance in future aquaculture and biomimicry exploitation.
- Biomolecules from polar organisms. We will identify and develop novel chemicals used by organisms in extreme environments for their potential use for innovative applications in industry and society.
Technology, innovation and training
- Use molecular (gene), biochemical and cellular technologies to understand physiological and ecological processes affect resilience/sensitivity to climate change.
- Use morphological and molecular (phylogeographic) technologies in taxonomy and phylogeny.
- Use and develop databases and mapping software to reveal patterns in biodiversity and predict future range changes.
- Use a range of advanced marine technology, including heated settlement plates for marine colonisation studies and new high definition video and photographic systems for mapping seafloor biodiversity.
- Continued strong commitment to post graduate training through NERC Doctoral Training Partnerships and other direct UK and international collaborations.
Influencing and leading international programmes
- Scientific Committee on Antarctic Research (SCAR) scientific research programmes State of the Antarctic Ecosystem (AntEco) and Antarctic Thresholds – Ecosystem Resilience and Adaptation (AnT-ERA); steering group of proposed Antarctic Terrestrial and Nearshore Observing System (ANTOS); SCAR Development Council
- International biodiversity data initiatives including: biodiversity.aq (the Antarctic biodiversity information system), the Global Biodiversity Information System (GBIF) and the Ocean Biogeographic Information System (OBIS)
- Participation in a series of meetings and workshops contributing to Marine Protected Areas in the Southern Ocean, and to the development of Antarctic Biodiversity and Conservation Strategies.Contribution to the Southern Ocean Observing System (SOOS), Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the United Nations Environment Programme World Conservation Monitoring Centre (UNEP-WCMC), the United Nations World Ocean Assessment, the Inter-governmental Panels on Climate Change and Biodiversity and Ecosystem Services (IPCC, IPBES), the Genomic Observatories Network and the European Marine Biological Research Centres (EMBRC).
