Dr. Tom Letessier
Adjunct Research Fellow
- RT @ReeFishNews: A new meta-analysis led by @stephmanel uses data from 243 species across 130 studies to show that median dispersal capacity is 42km but only 33km for fishes. This distance, certainly underestimated, connects three quarters of marine reserves globally. https://t.co/JjoU1F8wHa https://t.co/LE7U6ryLDY,
- RT @jb_jouffray: We used a machine learning approach known as 'boosted regression trees' and created a dedicated R package (ggBRT) for interpretation and visualisation available at https://t.co/xyK5Q1b4X5. All data and analysis script are open access at https://t.co/j2nHd9t98z #rstats https://t.co/jOpDgvoWwX,
- RT @JoneseyRM: Well that was a cracking set of talks! Unbelievably accurate tracking of poaching fishing boats by tagged albatross amongst other amazing things #ZSLtalks #BIOTscience,
I am a marine ecologist whose primary expertise lies in the understanding of open-ocean and pelagic ecosystems. I have a keen interest in pelagic biogeography, biodiversity, ecosystem function and conservation. My PhD studies involved quantifying the influence of bathymetric features on pelagic ecology using field sampling, statistical modelling techniques, and biochemical laboratory analysis such as stable isotopes and fatty acids.
I am currently working on pelagic predators, utilizing mid-water baited camera technology to inform conservation and management strategies. As part of my research fellowship I have coordinated remote field expeditions in Pitcairn, Chagos, New Caledonia, French Polynesia, Shark Bay (Australia), the Timor Sea, and the coastal Skagerrak.
