no that is gen Ai image. Our dean is a strong advocate for gen Ai use though, and I think this is more ethical way to promote pi day than dragging a goat to campus.

Our dean wants us to tether a goat on campus to graze to demonstrate the mathematical principles of pi, in celebration of #PiDay. This is wrong on so many levels.

Why leave the water if you are a fish? Despite being a major event in early tetrapod evolution, many living fish species occasionally leave water, but the reasons are not always obvious. Some do it to feed, some to escape predation, and some to cope with poor water quality, although rarely for long periods of time. Another intriguing possibility is that fish may use land to help regulate their body temperature.

We show that even short-term, gentle handling changes skin temperature and activity in salamanders, with implications for thermal physiology research and animal welfare. 🌡️🔥

Handle with care: when measuring temperature changes the temperature Measuring body temperature should seem straightforward, but in ectotherms, the act of measuring can be part of the problem. For especially small amphibians in particular, common approaches like cloacal thermometry require restraint and direct contact, raising the possibility that handling itself alters body temperature before it is even recorded. In this study, we asked a simple but important question: does brief, gentle handling measurably change the body temperature of salamanders?

Award season in the lab A lot of news has happened in the past month and I have been negligent about updating. All lab members have had awards, scholarships, and bursary announcements that warrant celebration! • Melane Denommé Stauder (PhD student) will be receiving the Jack Miller Graduate Award for the Faculty of Mathematics and Sciences this coming year. Stay tuned for a future announcement as I'm not sure this is public knowledge yet.

Try Before You Buy: How Experience Shapes What Bearded Dragons Prefer A recent paper from the lab, led by PhD student Melanie Denommé, examines a foundational assumption in reptile husbandry: that animals will inherently prefer naturalistic enclosures over simpler, more utilitarian ones. Using bearded dragons (Pogona vitticeps) as a model species, Melanie conducted preference tests in which lizards were given free choice between naturalistic and standard enclosure styles (Figure 1).

Too Hot, Too Cold, Just Right: The Goldilocks Effect in Garter Snake Habitat Use Our new paper, led by MSc student Harry Kumbhani and building on fieldwork conducted by former MSc student Curtis Abney, explores how Eastern Garter Snakes (Figure 1) navigate the complex thermal landscapes of wetlands in southern Ontario. Using detailed operative temperature models, which were copper snake replicas equipped with temperature loggers, our team quantified how three adjacent habitat types (closed forest, mixed shrub, and open peat; Figure 2) differ in the thermal opportunities they provide.

Oxytocin Neurons and the Rhythm of Warmth and Wakefulness A new study led by Morgane Vandendoren, Nicole Bedford, and others from Adam Nelson's lab at the University of Wyoming has uncovered a new role for oxytocin, the so-called “love hormone.” Published in eLife, the research shows that oxytocin neurons in the paraventricular hypothalamus act as a kind of biological switch, helping mammals transition from cooler, resting states to warmer, active ones.

Supercool Survival Strategies of Blue-Spotted Salamanders In the cold, temperate forests, long before spring fully arrives, blue-spotted salamanders (Ambystoma laterale) are already on the move. These small amphibians begin migrating to their breeding ponds while snow still blankets the ground and ice lingers on and in the soil. This is a risky strategy for a species that can’t survive freezing. Our recent Natural History note…
