Excited to share another paper from work I did during my PhD with @trishschulte.bsky.social and @madisonearhart.bsky.social. We looked at how fish embryos respond differently to constant and fluctuating temperatures! 🐟

Atlantic killifish are robust little fish, but now @tblanchard.bsky.social & co reveal that fluctuating temperatures while the embryos are developing in the egg can have beneficial and damaging consequences journals.biologists.com/jeb/article/...

New lake sturgeon work out investigating transcriptional shifts in the gill during early development mRNA changes associated with histone modifications, DNA methylation, and apoptosis were conserved across both populations, as well as population-specific processes 🧪🌎🌐🐠 tinyurl.com/bdekwzed

Different process which changed in the gill of lake sturgeon during early development.

these REUs are so crucial for undergraduates to get to do science, for their careers, and for all of us because undergraduates are our future and we need to support and nurture their brilliance ~ this is heartbreaking 💔 🧪👩🏻‍🔬🌎

Another paper from my PhD where we looked at the short and long term effects of raising embryos at two different temperatures 🐟 Interestingly hypoxia tolerance but not thermal tolerance was shown to be altered in juveniles.

How do early developmental conditions affect stressor resilience in fish later in life? We investigated this in a new paper lead by @tblanchard.bsky.social! 🧪👩🏻‍🔬🌎🌐🦑 We found that in killifish, sub-optimal developmental temps had lasting negative impacts on hypoxia tolerance later in life 👇🏼

Exposure to sub-optimal temperature during early development decreases hypoxia tolerance in juvenile Fundulus heteroclitus

Summary: Exposing Fundulus heteroclitus to a sub-optimal temperature during development reduces hypoxia tolerance but increases hif1α expression in juvenile fish and has no effect on thermal tolerance...

Survived my first ever term as a Lecturer, even though I still have lots to learn, my students are what made the class so enjoyable to teach. My biggest takeaway from teaching is to show students you care, and to that I look forward to what next semester brings.

two notes from students to say thank you with two chocolate bars.
