Hi bsky sci community! I’m new here, so here’s a Sharky introduction! I’m an ecologist interested in understanding shark movement, diet, and population dynamics in the San Francisco Bay! Hope you’ll join me on this new app journey 🌎 🦈 🫶🏻

Does tidal marsh #restoration "work", if the goal is bringing back key species AND the trophic interactions that support them? A thousand stable isotope samples later, we have answers! 💯 work by PhD student Megan Pagliaro:

Does tidal marsh restoration lead to the recovery of trophic pathways that support estuarine fishes?

Evaluation of tidal marsh restoration success is typically based on the recovery of habitat size and target species. However, food-web structure may provide valuable insight into ecosystem functionin...

I finally did it. My first chapter is FINALLY written and out for all to see. If you’ve attended my talks you 100% know what this is about. If you haven’t attended my talks, shark nostrils are more interesting than we thought. Enjoy! academic.oup.com/icb/advance-...
