Our lab was at the Toronto Zoo as part of Science Rendezvous. We had fun talking to kids and adults about the sense of smell of fish! @liamtigert.bsky.social @utscbiology.bsky.social @utscresearch.bsky.social

3)The responses to some odorants (L-cysteine) were more affected by hypoxia than the response to others (L-Arginine)

2) mild hypoxia (50%sat) decreased olfaction just as much as more severe hypoxia!

A 🧡 about some interesting findings from our latest paper:

1)external hypoxia not hypoxaemia (internal hypoxia) causes a decrease in olfactory sensitivity in seabream

Effects of hypoxia on the olfactory sensitivity of gilt-head seabream (Sparus aurata) Highlighted Article: Electrophysiology shows that low external oxygen levels can impair the olfactory sensitivity of a coastal marine fish species.

🐟 New paper out where we show that aquartic hypoxia affects the olfaction of marine fish! Work by @liamtigert.bsky.social during a @biologists.bsky.social travelling fellowship to work at CCMar with Peter Hubbard

In the lab 😁 finally getting around to testing a new piece of equipment - LI-COR DIC analyzer. Love the nice peak! This will support our climate change research on fish! @utscbiology.bsky.social @utsc.bsky.social Thank you to CFI for funding to buy this incredible machine!

From 1.5C to 2C of global warming is an increase by 33.3 percent. Many people assume that the negative impacts of this would also increase by only 33.3 percent. Unfortunately, that is not the case. The increase is non-linear.
This is one of the biggest missing pieces in public climate literacy.
