EASTBIO: Soundscapes of Recovery: Acoustic Indicators of Ecological Change in Scottish Rivers

EASTBIO: Soundscapes of Recovery: Acoustic Indicators of Ecological Change in Scottish Rivers

Research Question and Project Fit

Can sounds linked to freshwater invertebrate behaviour provide reliable evidence of river ecological condition? This St Andrews Biology doctorate connects freshwater ecology, behavioural annotation, acoustic analysis and community-facing conservation. Iain Matthews and Stefan Pulver are the named supervisors, and the advert specifies a 3–6 month CASE placement with Buglife. International tuition differences are covered for successful EASTBIO award holders; that is a competitive route, not a guaranteed funded place. The deadline is 16 November 2026, date only. Prior acoustics or machine-learning experience is expressly unnecessary because training is provided. Personal submission availability and the closing clock still need confirmation.

Research direction and evidence from original studies

The project asks whether behaviour-linked sounds of aquatic invertebrates can predict river ecological health. It proposes a reference sound-and-behaviour library in Years 1–2 using synchronised high-speed audio/video observations, followed in Years 2–3 by paired underwater recordings, macroinvertebrate-community data and water chemistry. The three advertised catchments are Dreel Burn, Fife, undergoing restoration; South Esk, Lothian, with mixed pressures; and River Peffrey, Highlands, described as restored. The last name retains the advertisement's spelling. Precise field locations and permissions need confirmation rather than an unverified name correction.

The scientific distinction is between identifying a sound source and establishing an ecological indicator. A recognisable acoustic event does not by itself establish species abundance, water quality or restoration success. Flow, weather, equipment noise, season, animal activity and site differences may change recordings independently of ecological condition. Paired biological and chemical observations make this a stronger proposed design than treating a single sound index as ground truth. However, the advertisement does not guarantee independent catchment validation, pre-restoration baselines or a causal restoration comparison. These are important design questions, not established project results.

Three original studies inform different parts of the work: one includes Pulver, while two are external comparisons. Their species, settings and methods differ from the proposed Scottish river indicator, so none validates it.

Behavioural context: Xu Ying, Zwart and Pulver, Journal of Experimental Biology, 2025

This study examines context-dependent movement in beetle larvae. The study tracks whole-animal and leg movement and shows that movement coordination changes with behavioural context and speed. This supports attention to behaviour when interpreting movement-linked sounds, but the study does not record river soundscapes or establish freshwater indicator taxa. Pulver contributed conceptualisation, writing and supervision; the statement assigns methodology and investigation to Xu Ying, and formal analysis to Xu Ying and Zwart. Do not credit Pulver with every measurement. The work concerns a terrestrial insect, with restricted experimental contexts; its behavioural findings cannot be assumed to transfer to aquatic communities. 2025 behavioural original.

Recording context: Lawson and colleagues, Remote Sensing in Ecology and Conservation, 2024

This study compares mobile and stationary acoustic recording in a Croatian lake. The study compares paired recording methods, addresses noise and reports classifier validation. The manually checked bird classifier had F1 0.75 for stationary versus 0.60 for moving recordings. Several apparent richness/abundance differences were not statistically significant; compositional turnover was informative. Underwater indices were deliberately interpreted as acoustic activity, not directly as biodiversity, because abiotic and human sounds contribute. This is a useful counterexample to equating greater acoustic activity or broader sampling with better ecological inference. It is a lake study, with surface bird classification distinct from underwater invertebrates, and neither St Andrews supervisor is an author. Lawson is first author; the publisher identifies Lawson and Kovac for correspondence, but the full technical contribution breakdown remains unclear. 2024 original, institutional version.

Reproducible characterisation: Rivas, Brizio, Buzzetti and Pijanowski, Methods in Ecology and Evolution, 2025

This study presents Rthoptera, an original insect-bioacoustics software contribution. The article describes package development, interactive measurements and tests. 98% software test coverage supports code testing; it is not a species-classification accuracy or river-health validation figure. Rivas conceived the package, developed code and wrote the manuscript; Brizio co-designed applications and tested functions; Buzzetti supplied expert feedback; Pijanowski provided guidance and funding. Neither project supervisor is a coauthor. Its relevance is reproducible sound characterisation and accessible analysis, not proof that the package handles every underwater sound or that R is compulsory for this PhD. 2025 methods original.

Together these studies support behavioural annotation, explicit noise controls and reproducible measurement. They do not establish a universal acoustic proxy. A reasonable assessment criterion is performance on recordings from a catchment, season or volunteer group excluded from model development. A second is whether an acoustic model adds information beyond flow, chemistry and sampling effort. Those are analytical decision criteria, not promised results or operational field instructions.

University, discipline and doctoral training

The intended awarding institution is the University of St Andrews, United Kingdom, with Biology the advertised host and “PhD with internship” the instructed application route. EASTBIO's information being hosted on an Edinburgh website does not create an Edinburgh degree. Pulver's affiliation in Psychology and Neuroscience is a supervision link, not evidence of a joint degree or permission to select a neuroscience programme instead. The exact registration code and supervisory division should be confirmed in the offer.

Biology's PhD framework specifies a literature review after four months, a progress report/review after nine months and annual subsequent reviews. Satisfactory nine-month assessment is required to continue. Full-time students are expected to submit within four years, followed by a viva involving an external examiner. This is a doctoral progression framework, not a four-year completion guarantee or automatic funding extension. Biology PhD framework.

The university's Biology page reports 84% of research activity rated 3-star or 4-star in REF 2021. Its subject-guide rankings refer explicitly to 2023. These dated unit/subject measures are contextual, not current river-ecoacoustics or individual-supervisor rankings. The concrete training opportunity—paired ecological evidence, an interdisciplinary supervisory setting and an advertised conservation placement—is more relevant than a general league-table label. Biology assessment scope.

The 2026–27 EASTBIO handbook provides research-training and placement context. Its generic PIPS arrangements must not replace the specific Buglife CASE placement of 3–6 months. Nor should a generic CASE allowance, research-training budget or placement bursary be treated as a personally approved cash enhancement. Exact 2027 CASE terms, timing and expenses need the award agreement. Dated training handbook.

Supervisors and Conservation Collaboration

The Biology staff profile identifies Iain Matthews as Senior Lecturer, with named doctoral supervision examples. Its listed publications are largely older; that list does not establish recent project-specific output or supervisory capacity. A public list of students is not a completion rate or proof of an available slot. The advertisement names Matthews; it does not detail lead-versus-day-to-day responsibilities. Matthews staff profile.

The official research profile identifies Stefan Pulver as Senior Lecturer in the School of Psychology and Neuroscience, affiliated with the Institute of Behavioural and Neural Sciences and Centre for Biophotonics. His research overview covers integrative movement neuroethology in flies, beetles and aquatic invertebrates. It explicitly lists BugLife Scotland as an external partner, strengthening the coherence of the advertised collaboration. This does not establish instrument allocations or transfer every technique in the lab to this student's work. Pulver current profile.

The CASE component places the student with conservation practitioners, community groups and citizen scientists in Guardians of Our Rivers to co-develop accessible monitoring. The Buglife programme description gives the Next Steps funding period as October 2024–September 2026, describes support for regional trainers and continuation beyond the funded period. These programme details do not confirm a 2027 host budget. The new advert's 3–6 month placement remains a specific proposal, while the precise successor programme, host supervisor, funding and practical arrangements require confirmation. Partner programme and dated scope.

Clarify responsibilities for field access, equipment maintenance, community coordination, permissions and data governance. The advertisement does not guarantee an individual hydrophone allocation or a funded long-term field team.

Funding, costs and support boundaries

The exact advertisement offers a four-year competitive EASTBIO BBSRC studentship, open to UK and international candidates, with UKRI-standard maintenance and UK-level tuition support. St Andrews will cover the Home–International fee difference for successful award holders. There is an explicitly supported international fee route; there is no basis to invent an unresolved overseas top-up for a funded winner. The award is not guaranteed merely by applying or obtaining a supervisor's nomination.

The programme FAQ confirms the waiver arrangement and distinguishes tuition, stipend and annual research support. It says visa and immigration health surcharge costs are not covered. Research/placement budgets are not unrestricted personal income. The specific advert does not promise an additional CASE stipend, name an approved individual grant or state an exact 2027 amount. Funding and international conditions.

The official UKRI table gives £21,805 minimum stipend and £5,238 fee level for 2026–27; the project materials do not specify a 2027–28 rate. Use those only as dated benchmarks. £21,805 divided by 12 is approximately £1,817 monthly, not a verified payment schedule. Four years of advertised support is distinct from doctoral registration beyond four years; extension fees and maintenance are not automatically covered. UKRI annual rates.

St Andrews' 2026–27 US federal-loan administration budget lists £14,313 for residence or rent/utilities/food, £5,200 personal living expenses, £2,000 travel and £1,200 equipment/books. Their non-tuition sum is £22,713 over a year, about £1,893 monthly. The £908 difference against £21,805 is an illustrative comparison, not a guaranteed personal shortfall. This administrative borrowing ceiling is not a housing quote or the 2027 cost of this field-based PhD. Avoid overlapping headings in a personal budget and establish deposits, travel and placement-related costs. Budget basis.

The government's Student-route financial guidance gives £1,171 monthly outside London for up to nine months, or £10,539 maximum. These are the amounts on the government page at the 13 October 2026 check, not a forecast for a 2027 visa application or a 12-month living budget. The same guidance normally exempts Chinese nationals from submitting financial evidence upfront, while retaining the requirement to meet the funds standard and allowing later requests. Documented sponsorship or CAS coverage should still be confirmed; exemption from upfront evidence is not an exemption from having adequate funds. Visa financial evidence.

Applicant fit, Chinese qualifications and materials

The research is advertised for interests in ecology, conservation, ecoacoustics, neuroethology, environmental monitoring or data science. No previous acoustics or machine-learning experience is required. A thoughtful explanation of transferable experience can help, but Python, R, prior wet-lab work or a completed sound classifier must not be invented as hard conditions. EASTBIO generally requires an upper-second undergraduate degree or international equivalent; the project's suitability and the university's assessment remain individual. A master's is not universally required. The Biology framework and competition rules describe general routes, not a guarantee of admission.

The China country page gives a general 78% minimum for an accredited bachelor's degree, with requirements depending on institution and degree. It does not certify that every 78% transcript meets the programme's equivalence assessment. Chinese nationals are not excluded by the international award route; fee status, academic equivalence and immigration requirements are separate questions. Some country-page fee-status/SELT wording is broad or dated and should not override the precise offer and current language policy. China qualification guidance.

The postgraduate English policy normally uses the School's taught-course profile, subject to higher requirements and formal offer conditions. Biology corresponds to Profile 3-D: IELTS Academic 7.0 overall and 6.5 each component. Test results are normally accepted within two years of programme start. Pulver's cross-School involvement does not establish a different language profile. An EASTBIO applicant may apply before taking an English test, but an eventual offer may require the language condition. PGR language policy. Profile 3-D.

The advertisement's five steps are the EDI survey, EASTBIO application form, St Andrews online application, choosing “PhD with internship”, and uploading qualifications, applicable English evidence and two references using EASTBIO's reference forms. Referees may use automated portal upload or the specified administrator route, pgrecbiology@st-andrews.ac.uk, handled by Rachel Horn. Generic university start-date flexibility is not this cohort's agreed start. Institutional research application route.

Central guidance permits one EASTBIO project across all hosts. Referees should be academic or professional and cannot be this project's supervisory team. The EDI survey availability through 17 November does not extend the project deadline. The EDI survey and visible form links do not by themselves establish that an individual application has been submitted. Current application guide.

Career and Transferable Skills

Training can develop the ability to assess ecological indicators, manage labelled data, compare model performance and communicate uncertainty to volunteers and practitioners. Those skills are relevant to conservation monitoring, environmental data analysis and behavioural or ecological research. They are reasoned skill mappings rather than measured employment outcomes, a guaranteed conservation post or a salary forecast.

Timing, Risks and Questions to Resolve

The deadline is 16 November 2026; no closing hour or time zone is stated. Confirm the submission route with St Andrews.

EASTBIO selection involves institutional eligibility/completeness checks, supervisor nomination, central shortlisting and panel assessment. The 30% international studentship limit, host caps and CASE allocation affect competition; they are not a China-specific ban or a personal success probability. The table lists 18 January nominations, 22 February invites, interviews in the week of 8 March and decisions in the week of 22 March. Its 2027 years follow the recruitment context where the table gives only day/month. A cohort expectation of 1 October is not an individual start contract. Selection timetable.

China is not an exempt nationality under ATAS, but the requirement depends on the assigned research subject/CAH code and offer/CAS conditions. The specific code was not established. It is an individual immigration question, not evidence of a nationality ban. ATAS rules.

Before committing, resolve personal degree/English equivalence; the exact application stage and deadline clock; award and 2027 stipend; Buglife's 2027 host arrangement, CASE timing and expenses; field locations, access and data permissions; supervisors' daily roles; and validation across sites, seasons and volunteer recordings. This is a credible proposed interdisciplinary training opportunity, with full international tuition support conditional on winning the competition. Its ecological forecasts and citizen-science usability remain research questions, with the species, setting and method limits described above.

Evidence and Sources

The recruitment materials list 19 October 2026 as the start of project advertising and 16 November 2026 as the project deadline; no closing hour or time zone is specified. These dates do not establish an individual submission status. The 2027 Buglife placement and successor programme arrangements remain unconfirmed. The cited studies concern beetle behaviour, lake recording and insect-bioacoustics software; none validates the proposed Scottish river indicator. Funding and cost figures apply only to their stated years and purposes.
