Event Description
- Full Description:
- Hi everyone!
Hope this finds you all well.
The Centre for Marine Science is happy to invite you to a special marine postgraduate seminar, next Tuesday 18th August, at 1pm.
The seminar will be held on Zoom. Please register in advance for this meeting: https://uqz.zoom.us/meeting/register/tJ0vdeqsrzIjE9K3jLyYVgJ1REbsCkZ-7bzx
We will be joined by two guest speakers: PhD students Sheldon Rey Boco from Griffith University and Brett Lewis from Queensland University of Technology. Join us in exploring the impact of future climate scenarios on the Irukandji jellyfish and in the establishment of the first coral attachment model to inform out-planting restoration.
1) Extreme, but not moderate climate scenarios, impart sublethal effects on polyps of the Irukandji jellyfish, Carukia barnesi
Sheldon Rey Boco, PhD candidate, Griffith University
Ocean warming and acidification stress many cnidarian species but most experiments test responses to the most extreme climate scenarios, despite moderate scenarios being most likely to occur. We examined the combined effects of warming and acidification on the reproduction, respiration, mobility and metabolic composition of polyps of the Irukandji jellyfish, Carukia barnesi. The experiment consisted of two orthogonal factors: temperature (current 25 °C and future 28°C) and pH (current (8.0) moderate (7.9) and extreme (7.7)). All C. barnesi polyps survived the experiment, unlikely to be affected by the more optimistic climate scenario and will tolerate, but perhaps not thrive in the most extreme climate conditions.
2) Substrate attachment in Scleractinian corals to inform out-planting restoration
Brett Lewis, PhD candidate, Queensland University of Technology
Asexual reproduction via fragmentation is common for many corals and yet, the process by which coral fragments attach is poorly understood. Robust fragment attachment is also the primary factor governing success of the outplanting-based reef restoration – a practice that is accelerating worldwide. Using novel imaging methods, we established the first coral attachment model and created a much-needed baseline for substrate attachment in Scleractinian coral. We are now using a range of taxa to characterise and compare the attachment and identifying potential to enhance or accelerate the natural process.
We hope to see you on Zoom next Tuesday!
Cheers,
The Centre for Marine Science
