Paleoecology PhD position – Northumbria University

White Sea meromictic lakesas rich archives of palaeoenvironmental change: Not only do lakes in the White Sea region of the Russian Arctic provide ideal sites from which to generate records to constrain deglaciation and postglacial sea-level change, but they also represent a rare and globally unique laboratory providing insight into lake responses to climate change. Due to rapid geological uplift (at the fastest rates seen in the Russian Arctic), the lakes are at various stages of separation from the sea, driving them to sequentially shift from a partially to permanently stratified (meromictic) state . In this way, a unique series of lakes exist, exhibiting a gradient of environmental conditions. As ~16% of lakes globally are expected to undergo less frequent mixing and approach meromictic states by 2100AD3 – a regime change that will profoundly modify their role in regulating global climate – the White Sea region can be viewed as future representation of the Arctic under future climate change. Ongoing monitoring by project partners at Lomonosov Moscow State University shows warming of these lakes has accelerated over the last decade. However, in order to assess the impacts of future climate change, we need to understand how these lakes have responded to past environmental changes over much longer geological timescales. The locality of the White Sea presents a myriad of opportunities to investigate the drivers of past and current climate change, and the effects on high Arctic lakes. In this project, you will address one or more of the key questions above depending on your area of expertise, and will be supported in the development of a multi-disciplinary research strategy, which combines proxy records from lake sediment cores and numerical modelling. You will conduct fieldwork from the White Sea Biological Research Station with support from colleagues at Lomonosov Moscow State University, and undertake a range of laboratory analyses, including diatoms, chironomids, Xray Fluorescence scanning, and radiocarbon dating. Depending on your interests, there will be exciting opportunities to use your newly developed proxy records to inform earth systems models.

Harmful algal blooms (HABs) formed by planktonic microalgae lead to
devastating fish kills worldwide. Only a few of the causative agents are identified
so far and even less is known about their toxicity. In a recently established
working group we are dealing with potentially toxic compounds produced by
microalgae which represent a potential threat for food safety and food security.

PhD position in multiple stressor river ecology

We are seeking a doctoral researcher to participate in the subproject Functional and compositional responses of stream microphytobenthic communities to multiple stressor increase and decrease in the CRC RESIST with a focus on microphytobenthos / diatoms. The project will use digital microscopic, molecular biological and pigment analyses to characterize the responses of stream microphytobenthic communities to increasing and decreasing multiple stressor load. Expected start January 1st 2021 or when position is filled.
