Overview

Biodiversity is undergoing alarming declines worldwide. Modern species extinctions are predominantly attributed to environmental factors, mostly climate change and habitat destruction. However, sexual selection –competition over mates–drives evolution of intrinsically ‘costly’ traits (calls, ornaments, displays) that increase chances of population collapses, thus potentially leading to non-ecological extinctions. But, is sexual selection a factor responsible for ongoing species extinctions? Despite its enormous implications for our understanding of current and future global biodiversity, this question remains unresolved. Existing theories linking sexual selection to extinctions make contradictory predictions –some models suggest that sexual selection accelerates extinctions, while others suggest that it mitigates species declines. Unfortunately, empirical evidence remains limited.

This project implements the first global-scale research programme investigating whether the worldwide extinctions of one of nature’s most threatened lineages, amphibians, are accelerated by the widespread evolution of a particularly costly sexual trait –advertisement calls, known to enhance mortality via energetic and ecological costs. Using a dataset spanning morphological, ecological, life history, genomic, climatic, geographic and phylogenetic data for 7,000+ amphibian species, this project aims to establish the mechanistic connections between sexual selection and extinctions at an unprecedented scale. This project is part of the Global Amphibian Biodiversity Project (GABiP) led by Dr Daniel Pincheira-Donoso.

This project will be supervised by Dr Daniel Pincheira-Donoso and Dr Hansjoerg Kunc of Queen’s University School of Biological Sciences.

Biological Sciences overview

The School of Biological Sciences provides PhD and MPhil (research degree) programmes in subjects ranging from basic biochemistry, molecular genetics and cancer research, to agricultural science, marine ecology and the economic evaluation of ecosystem services and food retailing. If you have a topic or research question in mind, please use the Find a Supervisor link (see Apply tab) to identify the most appropriate member of staff to support your idea. If not, don't worry, we regularly advertise funded projects and there is no harm in browsing our academic staff profiles for inspiration and then contacting whoever seems best: we are very open to applications from suitably qualified people interested in scientific research. In every case, a PhD or MPhil course provides the means of being part of a cutting edge scientific research team and contributing to genuine new discoveries or the development of new methods for practical use. If you cannot study full time, we offer pro-rata part time research degree programmes as well.

To help orientation, the School is organised into three research theme clusters:

- Ecosystem Biology and Sustainability
- Microbes and Pathogen Biology
- Food Safety and Nutrition

Ecosystem Biology and Sustainability:

In this cluster, you could research biodiversity and ecosystem services for environments ranging from tropical forests to deep oceans, using field techniques and skills such as wildlife tracking, taxonomy, geostatistics, molecular and genetic ecology, foodweb-analysis, microcosm and mesocosm experiments and mathematical/computational methods. Alternatively, you could study the behaviour and temperament of wild, agricultural or domestic animals and their implications for welfare and ability to respond to environmental change. Potential research projects include phylogenetic analysis of rare and newly discovered species, examination of ecological interactions in tropical systems, agricultural soils, or marine communities, using state-of-the-art genetic analysis, surveys using drones or satellite tagging, or experiments in tanks and field plots, including careful and ethical examinations of animal behaviour. Projects range from theoretical analysis of stability in ecosystems, through discovery of new species and mechanisms of interaction, or responses to climate change, to the assessment of EU agri-environment schemes, development of new methods for commercial fisheries management and economic evaluations of conservation measures. Projects very often have an international dimension and include collaboration with other researchers worldwide.

Microbes and Pathogen Biology:

This cluster covers a diverse array of research interests united by an emphasis on molecular approaches applied to both fundamental and applied questions over the range from molecular to ecological systems. These interests include biochemistry, food safety, microbiology and parasite control with applications in human and animal health, nutrition, plant and soil sciences, and agricultural development. We have a long-standing reputation in parasite biology and in applied microbiology (for example in clearing land of contamination) as well as strong contributions to fundamental methods in understanding cancer, developing veterinary vaccines and molecular detectors for toxins and diseases. The common thread is our strong molecular approach using and developing cutting edge genomic, transcriptomic/proteomic methods. Research students in this cluster enjoy a range of strong international links across Europe, Asia, North and South America.

Food Safety and Nutrition:

Research opportunities offered by this cluster span the entire food chain "from farm to fork" with a strong emphasis on food safety and nutrition, public health and food security. In this cluster you would conduct research under the supervision of leading scientists based in the Institute for Global Food Security and benefit from integration with business experts, helping you gain leadership positions nationally and internationally.

People teaching you

Dr Keith Farnsworth
Chair of School Postgraduate Research Committee
School of Biological Sciences
For a PhD you will have a principal and second supervisor who advise your independent studies and will be supported by a wider team from the academic staff - who they are, of course, depends on your project. For further details on any aspect of postgraduate research degrees within the School of Biological Sciences, contact: biosciences-pg@qub.ac.uk.

Learning Outcomes

A research degree offers students an opportunity to foster their capacity for independent research and critical thought. It also allows students to explore an area of interest and so understand and solve theoretical and practical problems within the field. Undertaking a research degree can enhance a student’s written and oral communication skills and a PhD is almost always a formal requirement for an academic post.

Assessment

Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present drafts of their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.

This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.

The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.

Feedback

Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.

Facilities
Full-time research students will have access to a shared office space and access to a desk with personal computer and internet access.
