Plankton are the microscopic plants and animals at the base of the marine foodweb that produce half the oxygen we breathe and support most of the fish we consume. Despite nearly a century of research into the efficiency of marine foodwebs, there remain key unanswered questions about how some of the largest fisheries in the world such as those for tuna are supported in the vast nutrient-poor regions that have very little plankton. We will explore this conundrum by testing the general marine ecological theory that the length of food chains is critical to the amount and distribution of fish in different regions of the ocean. The general theory posits that short food chains are efficient at transferring energy from plankton to fish, as there is less energy loss through respiration compared with long food chains. This talk will explore how getting the zooplankton right in mathematical models of the marine foodweb is important for explaining the amount and distribution of fish in the ocean.


About Statistics, modelling and operations research seminars

Students, staff and visitors to UQ are welcome to attend our regular seminars.

The events are jointly run by our Operations research and Statistics and probability research groups, and colleagues in the Centre for Applications in Natural Resource Mathematics.

Seminars are held on Tuesdays from 11am to 12pm in Room 67-442 of the Priestley Building (Building 67).

Information for speakers

Plan to speak for up to 40 minutes, and allow up to 15 minutes for questions and discussion.

Pitch your presentation to an interdisciplinary mathematical audience.

To avoid technical delays on the day, contact us a few days in advance of your presentation to discuss requirements.

You can either email us your presentation in advance, or save it to a memory stick. Microsoft PowerPoint presentations and PDFs are the most convenient file formats, but you can also run the talk from your own laptop.
