Ecological impacts of microplastic pollution in freshwater habitats
Position type: PhD position
Location: Anglia Ruskin University, Cambridge (UK)
There is now so much plastic on our planet that microscopic plastic particles (‘microplastics’) are the most abundant form of solid waste on Earth. Global plastic production is ever increasing, having grown from 1.5 (in 1950) to 322 million tonnes in 2015 and, each year, at least 10% of this plastic ends up as litter in aquatic environments. The majority of the plastic found in the world’s oceans originates from land, transported to marine systems along river networks. Despite the fact that many freshwater environments, including rivers, lakes and canals, are heavily contaminated by plastic waste, research on plastic pollution in freshwaters is still in its infancy. Freshwater habitats such as wetlands, rivers, aquifers and lakes provide vital benefits and services such as drinking water, water for food production and habitats for aquatic life and birds. Understanding and reducing the risk that microplastics pose to freshwater ecosystems is, therefore, an urgent research priority.

This PhD project will:
1. Quantify the distribution, abundance and type of microplastics in urban and rural freshwater habitats. Via collaborations with the Department of Biomedical and Forensic Sciences a Fourier Transform Infrared Microscope will be used to determine polymer types of the microplastics
2. Assess the potential impacts of microplastics on biodiversity, foodweb structure and ecosystem functioning in freshwater habitats The results of this project will generate essential novel data on the presence and effects of microplastic litter in freshwater habitats.
Recommendations on monitoring/mitigation will be established to provide managers with important information for policy-making decisions.

BBSRC-iCase project: Application of Molecular Tools to Update aquatic Ecotoxicology Monitoring
Position type: PhD position
Location: University of Nottingham, Nottingham (UK)
Application deadline: 2019-06-30
The detection and identification of species-specific DNA from water samples is a rapidly expanding field in ecology and has considerable commercial potential. To date, most commercial applications are in the detection of environmental DNA fragments by q-PCR to detect endangered wildlife species. Metabarcoding, using the latest deep sequencing technology, is revolutionising how we assess biological communities and is suited to the concurrent detection of a diverse range of species from water samples. This inter-disciplinary studentship project aims to develop a completely novel application for the detection of aquatic populations of organisms using both q-PCR and metabarcoding: to detect and quantify a wide range of invertebrate, phytoplankton and zooplankton species in aquatic ecotoxicity studies. Such studies are crucial for the testing and safety assessment of new and existing pesticides or pesticide formulas. The continuing development of pesticides is essential for improving crop production, particularly in light of current environmental pressures, such as climate change, increasing the occurrences of drought and flood events during growing seasons. Alongside the growing political and economic pressures to produce greater numbers of crops from ever decreasing available land. The necessity of pesticide use in the agricultural industry, means safety for non-target species needs to be rapidly and thoroughly assessed to allow these products to enter the marketplace and current approaches are both time and cost expensive. These DNA detection methods have the potential to compliment, streamline, or eventually replace, the traditional microscopy techniques. The project will include full training in a range of molecular techniques including PCR, qPCR, metabarcoding, next generation sequencing, and bioinformatics development. The latter will involve the design of bespoke bioinformatics methods in collaboration with the University’s Advanced Data Analysis Centre. Full training in conventional ecotoxicity methods will also be provided by the industrial partner and will include industry standard ecotoxicological experimental design, microscopy for taxonomic identification and enumeration of indicator species and the growth of monocultures. These taxonomy methods are rare and highly desirable skills in the ecotoxicology field. The study will be primarily based in the School of Veterinary Medicine and Science (SVMS) at the University of Nottingham’s Sutton Bonington Campus, a recognised centre for excellence in Global Food Security. The student will join a dynamic and very experience research group ( ; tab: Research Group) who are developing novel molecular diagnostics and therapeutics for a wide range of applications. The student will also undertake placements with the project’s industrial sponsor Cambridge Environmental Assessment (CEA); this is a highly regarded, multi-disciplinary consultancy and research organisation specialising in the area of environmental toxicity.

This project will be supervised by Dr Kevin Gough (SVMS), Dr Tania Dottorini (SVMS), Professor Richard Emes (SVMS) and Dr Nadine Taylor (CEA).

Postdoctoral Research Associate - Aquatic Ecology Group
Position type: Post-Doc position
Location: Oak Ridge National Laboratory, Tennessee (USA)
The Aquatic Ecology Group within the Environmental Sciences Division at Oak Ridge National Laboratory (ORNL) seeks a postdoctoral researcher with an understanding of aquatic biology and chemistry, with a specific focus on contaminant behavior and bioaccumulation in freshwater systems.

The successful candidate will work collaboratively with an interdisciplinary team of environmental scientists at ORNL to understand the chemical and ecological factors controlling mercury methylation and bioaccumulation in contaminated aquatic systems, and will develop experimental designs aimed at mitigating methylmercury bioaccumulation. Mercury is one of the most pervasive and widespread contaminants worldwide but the relationship between environmental mercury concentrations, methylmercury production, and mercury bioaccumulation is poorly understood. Because methylmercury bioaccumulation in fish poses both a human health and ecological risk, there is a need to understand both the chemical and ecological drivers of mercury bioaccumulation in aquatic systems. In particular, the candidate will examine the effects of filter feeders on mercury dynamics in stream systems. As keystone species in freshwater ecosystems, freshwater bivalves can drastically affect water quality, habitat, and food web structures, and consequently their presence may also affect mercury bioaccumulation and trophic transfer.

Responsibilities will include laboratory experiments to determine mussel filtration rates and bioaccumulation rates, mesocosm experiments to determine impacts of mussel introductions on mercury and nutrient dynamics in flowing systems, and field work (water quality measurements, caged mussel deployments). The results from this project will be useful in guiding future remediation efforts at Oak Ridge, but will also provide a fundamental understanding of the processes governing mercury bioaccumulation in stream systems.

12 Early Stage Researchers (3-years PhD positions) within the MSCA ITN MARSoluT - Managed Aquifer Recharge Solutions Training Network
Position type: First Stage Researcher (R1)
Location: Multiple locations, see work locations below.
Application deadline: 2019-06-15
Managed Aquifer Recharge (MAR) – storing water in aquifers during times of excess – is a key strategy to enrich groundwater resources in water scarce regions by providing intermediate storage, addressing the typical mismatch between water demand and availability. It can help to mitigate the effects of climate change, and to support water-related environmental services. However, MAR is characterised by complex interaction of physical, biological and hydrochemical processes influencing water quality and the sustainability of infiltration rates. Individual processes are in principal known, but there is a significant knowledge gap on how they are linked and affect each other. MARSoluT addresses this knowledge gap by a collaborative effort in a multi-disciplinary team.

Applicants from all relevant research fields are encouraged to apply, namely geosciences, engineering, hydrology, and hydrochemistry. The selected candidates will perform high-level research activities towards a PhD. The MARSoluT (Managed Aquifer Recharge Solutions Training Network) Innovative Training Network (ITN) is funded by the Horizon 2020 Marie Skłodowska-Curie Action of the EU.
