2018 Fiscal Year Research-status Report

Penguins as ocean sentinels: using video loggers attached on predators to understand the ecological niche of jellyfishes in Antarctica

Research Project

Project/Area Number 18K18183
Research InstitutionNational Institute of Polar Research

Principal Investigator

THIEBOT J.B.  国立極地研究所, 研究教育系, 特任研究員 (70723691)

Project Period (FY) 2018-04-01 – 2020-03-31
Keywordstrophic interactions / predator-prey / bio-logging / Antarctica / jellyfish / penguin / habitat modelling / global changes
Outline of Annual Research Achievements

During FY2018, the initial plan was closely followed and there was significant progress on several aspects of this project:
- video-loggers were deployed on Adelie penguins in Antarctica, from 9 different sites (8 teams, 7 countries). This is 2 sites more than initially planned, at no extra cost for the project. In total 127 individuals were surveyed using video loggers, building the basis for a sound analysis.
- accelerometers bought from this project were deployed on penguins and retrieved, from two different sites.
- preliminary analyses show no difference in prey availability and jelly consumption between sites.
- a paper has been written, submitted and is now being revised, highlighting the importance of jelly prey for animals including penguins.
- this work has been presented at an international conference (Pacific Seabird Group meeting - USA), where it was awarded a prize from the jury.

3: Progress in research has been slightly delayed.

Reason

As a consequence of the success of the international net-working forming this project (9 sites surveyed by 8 teams from 7 countries), more video data have been collected than initially planned. The expected volume of data was 90 hours of video; and the collected data amount to 635 hours. Analyzing these video data will take longer than expected, and thus final habitat modelling analyses will be conducted at a later stage.
There was an accident on the field, with one team member injured. No jellyfish sample could be collected. As a consequence, the plan to analyse calorimetry of these jellyfish samples, will not be possible this year. Instead, I will use values of calorimetry previously published from other jellyfish species.

Strategy for Future Research Activity

The first priority is now to finish analyzing all video data, and re-submit the first paper from this project.
Then, it will be possible to conduct final analyses on prey availability and habitat modelling, at the scale of Antarctica. A high-impact paper will be produced from these results.
Considering that no jellyfish sample was collected during this past field season, I will not go to the UK in FY2019 to conduct calorimetry analyses. Instead, I will use the funds to attend the International Symposium on Jellyfish Blooms, where I will present my work and develop connections with researchers working on biochemical analyses of jelly tissues. Using existing results will save time on this project, to ultimately estimate the carbon fluxes from these predator-prey interactions.
