Novel technology for endangered and invasive crayfish management
University of Leeds ：Faculty of Biological Sciences
Supervisor：Dr Josie South, Prof Alison Dunn
Application Deadline ：Wednesday, January 05, 2022
Competition Funded PhD Project (Students Worldwide)
About the Project
Background
Invasive non-native crayfish cause US$ 61 million a year in damage and management costs worldwide and pose a severe and increasing threat to native biodiversity as ecologically destructive omnivores and ecosystem engineers. Burrowing by invasive crayfish causes structural damage to reservoirs and watercourses which negatively affects ecosystem services, such as water supply and flood defences water services. Invasive signal crayfish have also contributed to the severe decline of native endangered white clawed crayfish within Europe. Assessing populations of crayfish is therefore a conservation and biosecurity imperative which is hampered by the biases and short falls of current sampling techniques.
Novel and exciting technologies, such as Remote Underwater Video (RUV) and environmental DNA (eDNA) are the future in biodiversity monitoring. These tools are at the pioneering edge of research and innovation. The aim of this project is to develop and test a variety of RUV methods, including baited RUVs (BRUVs) and Remote Operated Vehicles (ROVs), i.e. remote controlled submarines, and in combination with other techniques for detecting signal crayfish and white clawed crayfish with a view to improving information flow to facilitate more effective and targeted management. The student will complete field and laboratory work using these tools to help answer fundamental questions regarding crayfish conservation and invasion ecology while providing an applied dimension with regards to intervention and management strategies.
Objectives
Determine novel technology effectiveness in comparison with traditional methods
Explore differences in detection probability between RUV, BRUV, ROV compared to manual trapping, Artificial Refuge Traps (ARTs) and eDNA
Determine environmental limitations for RUV such as turbidity and habitat type.
Assess novel molecular methods to monitor crayfish as well as to add value in tandem, for example in the detection of crayfish plague.
Provide first data on distribution and population structure along a longitudinal gradient
The student will use the optimal technology to sample a series of catchments and reservoirs across the length of the U.K. to identify differences which may be driving invasions
Classify key microhabitat and water parameters for native and invasive crayfish
Determine crucial environmental parameters for both species to determine habitat and niche overlap and pave the way for habitat restoration interventions.
Approach:
This project will largely be field based surveys, video analysis, GIS modelling and potential for a lab-based study.
Training:
This project crosses core ecology with real world application and innovation in technology. At the University of Leeds the candidate will be jointly supervised by JS and AD. With JS’s research group they will be trained in field approaches in novel technology and survey design for conservation and management. With AD’s research group, they will receive training in INNS ecology and in biosecurity treatments. The candidate will spend 3 months working with APEM consulting to understand industry requirements and assist in developing their ROV survey protocols and designs. The candidate will learn skills in freshwater species identification, crayfish conservation, survey design and analysis, GIS, and non-native species management. All supervisors have extensive experience of supervising PhD students as well as different aspects of crayfish ecology and offer a supportive environment to enable the student to fulfil their project aims, undertake professional development and improve their career prospects.
Impact:
The project places environmental science and water engineering at the heart of responsible management of natural resources (NERC vision). It will lead to publications in high quality scientific journals and inform APEM operational practice. Societal impact includes reducing threats to water supply, benefits to biodiversity and ecosystems processes through the prevention of the spread of aquatic invasive species.
Entry Requirements:
Applicants to this project should normally have a first class British Bachelors Honours degree (or equivalent) in an appropriate discipline, such as Biology, Zoology, Ecology or related areas and/or a Masters qualification in a related area. Some experience in field work is desirable, but not

Sustainable valorisation of bio-based platforms
University of Auckland：Department of Chemistry
Supervisor：Dr Jon Sperry
Application Deadline ：Applications accepted all year round
Funded PhD Project (Students Worldwide)
About the Project
The field of chemical synthesis is under constant pressure to produce molecules in a timely, economical and sustainable fashion. This project will involves subjecting bio-based building blocks to heterocyclisation and heteroannulation reactions using both electrochemistry and mechanochemistry. These synthetic procedures generate a negligible waste-stream, thus providing a valuable contribution to the fledgling field of sustainable chemical synthesis. It is anticipated the new methods developed during the course of this project will lead to a paradigm shift in bio-based fine chemical production
Funding Notes
Scholarship funding up to NZ$27,500 per annum for three years. Tuition fees are also paid (3 years)
Dielectric diagnostics for charged particle beams

About the Project
For our location in Hamburg we are seeking: PhD student
Limited: 3 years | Starting date: earliest possible | ID: MDO006/2021 | Deadline: open | Part‑time
DESY, with its more than 2700 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.
Short electron bunches with durations in the femtosecond regime are sought after in a growing number of applications. For example, accelerator-driven X-ray sources like the EuXFEL require them to produce comparatively short light flashes. The current state-of-the-art diagnostic methods for such short bunches, based on radio-frequency deflecting structures, reach the required time resolution. However, they are high in cost and destructive for the electron bunches, preventing them to provide a live characterization of the bunches during operation.
DESY is developing novel charged particle beam diagnostics at the dedicated accelerator research and development facility ARES, and is looking for a PhD student to join this effort within the team running the radio frequency linear accelerator ARES. The main topic will be the development of a non-destructive dielectric structure-based charged particle beam diagnostic from simulation to device design to the proof-of-principle experiment at ARES. This will be complemented by operation and further development of the ARES linac. This research will be conducted in a very collaborative environment with SLAC, Stanford University, UCLA, FAU Erlangen and PSI already working together on experiments at the ARES linac.
About your role:
Simulation of charged particle beam interaction with dielectric micro-structures
Development of a prototype design
Planning and running of proof-of-principle experiment
Participation in the operation of ARES linac
Software development for machine control and data analysis
Participation in the on-going dielectric laser acceleration experiments
