Full Time Fixed Term (until 30/06/2026)
Tuesday 20 June 2023
University of Southampton, School of Geography & Environmental Science (SoGES).
Start Date from 1st September 2023.
A range of metrics show freshwater ecosystems as amongst the most vulnerable on global scales, yet systematic solutions for their recovery or restoration are not available anywhere in the world. Recovering a lake that has undergone a regime shift is not straightforward, with hysteresis and the strength of new feedback loops often causing failure. The holder of this full time post will undertake novel scientific research on freshwater lake ecosystems as part of the exciting NERC-funded project entitled ‘Recovery pathways for lake ecosystems’ awarded to Prof. Pete Langdon and colleagues. The project goal is to quantify the balance of factors influencing the recovery of freshwater ecosystems from undesirable (eutrophic) states. We aim to provide a unifying theoretical and practical framework for understanding what drivers and within-lake processes influence lake recovery pathways. This will be developed through three work packages, comprising data assimilation (WP1), empirical analyses (WP2) and system-based modelling (WP3), working with lake system stakeholders across all WPs.
The researcher will work on three main tasks providing the opportunity to gain skills in sampling design, fieldwork (UK and overseas), microfossil, macrofossil, geochemical and molecular data collection approaches, data analysis and modelling.
(i) Collate and review globally available data from lakes that have been subject to eutrophication, and subsequently have started or undergone full or partial recovery (WP1). (ii) Generate comprehensive full ecosystem datasets (multiple food-web trophic levels) from lakes that have undergone full or partial recovery. We will analyse new sediment cores across representative lake types (deep/shallow, large/small) where good information exists across sufficient time horizons on drivers and resolution. Analyses will include microfossils and macrofossils across all trophic levels, geochemical and molecular indicators and driver data (WP2).
(iii) Combine results from (i) and (ii) to (a) quantify trajectories and rates of recoveries; (b) identify the most influential and fastest/slowest responding biotic groups; (c) determine which feedback loops are likely to maintain each state; (d) compare composition and resilience of the recovered ecosystem to the system prior to impact; (e) estimate the impact of recovery mode (linear, stepwise, or hysteretic) on the new ecosystem structure (WP1&2).
You should have a PhD* or equivalent professional qualifications and experience in freshwater palaeoecology.
The post holder will work with both Prof. Pete Langdon (SoGES) and Prof. Helen Bennion (UCL) across WP1 and 2. Additionally, they will contribute data, and collaborate with the modelling team (and PDRA 2 – WP3), who will be led by Prof. Simon Willcock (Rothamsted) and include Prof. Patrick Doncaster (School of Biological Sciences [SoBS] Southampton), Prof. John Dearing (SoGES) and Dr Greg Cooper (Sheffield). The post holder will benefit from the early-career support opportunities available across both Schools in Southampton, with additional support and input from project colleagues at other institutions. In addition, they will be part of the wider team, including experts working on a range of different palaeoecological techniques (notably pigments – Dr. Virginia Panizzo, Nottingham and Prof. Suzanne McGowan, Netherlands Institute of Ecology; sedimentary ancient DNA – Dr. Jan Janouškovec, SoBS), and statistical techniques (Dr. Roseanna Mayfield, Newcastle and Dr Rong Wang, NIGLAS, China).
