Why Important:
🔹Expands GHH ecological knowledge in NW Atlantic; some individuals stay in the Bahamas all year.
🔹So the Bahamas shark sanctuary could be an all-year refuge, key for regional GHH rebuilding goals.
🔹We must analyse genetic samples to see how these GHH fit in the NW Atlantic population.

🔹Year-round residency of Andros-caught GHH in Bahamas w/ site-fidelity to & high use of habitats along Andros reef dropoff & flats.
🔹Possible mating + small juvenile sightings: Andros could be a reproduction ground.
🔹GHH mainly ate barracuda & small sharks/rays, linking pelagic & shoreline foodwebs.

Spring may bring an exciting shark movement modelling project, helping conserve these endangered creatures. I'm blessed to work with friends on projects for a better planet. I hope you've got positives to look forward to & your life is enriched by the connections you've made and work you do.

2025 starts with a workshop in San Diego with mid-career shark scientists, discussing shared challenges & building a support network we hope will benefit us for years to come. I'm also running the 1st US West Coast alumni meetup for Hampton School alumni on April 17 in San Francisco.

With a stellar team, I co-first-authored a paper in top journal Science Magazine, explaining the ecological role of sharks, and why it’s so important to protect them www.science.org/doi/10.1126/... thanks SayoStudio, Marc Dando, & Kylene Gilmore
Ecological roles and importance of sharks in the Anthropocene Ocean
In ecosystems, sharks can be predators, competitors, facilitators, nutrient transporters, and food. However, overfishing and other threats have greatly reduced shark populations, altering their roles ...

With NOAA Fisheries we modelled juvenile smalltooth sawfish habitat in SW Florida, highlighting challenges and conservation opportunities (link coming soon).

Four years in the making, with friends from Bimini (2006), GMIT (2013), and @fiu.bsky.social (2021), we showed the movement & hunting patterns of lemon sharks across tides & as they grew up tinyurl.com/yz83yasj
