We have the most photogenic campus

Excited about a new preprint from PhD candidate Megan Heft, showing that nestling provisioning rates in male tree swallows are not limited by the male's risk of overheating (in contrast with previous studies of females) 🧪 #ornithology #science

If you're a fish tracking nerd you know and love the sight of this pink foam

Caught a couple northern sunfish in a beach seine today; first time ever seeing these for me (in the Otonabee River near Trent U).

Diagram of a template design for a CTmax apparatus. Aeration, mixing mechanisms (pump), and heating elements are in an ‘equipment section’ that is physically separated with a screen from the part of the arena containing the animals (‘animal arena’; here with fish). A submerged temperature sensor (or data logger) is used to log temperatures, in addition to a temperature sensor with a display that is used to score CTmax in real time. The time and temperature should only be visible to the data recorder (and/or video camera), not to the person observing animals for end points.

Raby et al. provide a comprehensive, practical guide for designing and conducting experiments to measure critical thermal limits, with an emphasis on CTmax 🌍 🧪 👇

Incredibly nerdy paper, but should be useful I think.

This was a product of a pre-SEB writing retreat a bunch of had in Czechia last year.

Raby lab retreat this week at Harkness Lab of Fisheries Research was a great success!

Thanks to the ghost of F.E.J. Fry for writing inspiration 👻🐟
