Congrats, Dr! @melaniedscientist.bsky.social

Periodic reminder that we should avoid testing the Normality of the response variable. For a linear model, what matters is the Normality of residuals (and not that much). Visual checks better than test. #statistics

🚨New paper in JEZ-A 🦎 In Tropidurus catalanensis, sprint speed isn’t about size, testosterone or muscle enzyme activity. Instead, fast lizards show greater cardiac oxidative capacity, which is vital for post-exercise recovery doi.org/10.1002/jez....

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…

I'm extremely happy to share that in August I'll be starting a post-doc in Dr. Carlos Navas' lab at Universidade de São Paulo! With a fellowship given by the São Paulo Research Foundation, I'll study the mechanisms underlying behavioural fever in amphibians and reptiles 🐸🦎🌡️

Salamanders need to make sure their skin stays wet enough to survive living on land. Giacometti & co recently showed that salamanders can sense the humidity in the air and seek out areas that will stop their skin from drying out journals.biologists.com/jeb/article/...

Faculty of Math and Sciences Best PhD Dissertation Award to Danilo Giacometti Congratulations Dr. Danilo Giacometti! The Faculty of Mathematics and Sciences at Brock has awarded you the FMS Best PhD Thesis Award. A supervisor could not be prouder!

And all 5 chapters published before the thesis defense! Amazing! Makes the committee kind of irrelevant in a good way.

Extremely happy to share that I successfully defended my PhD yesterday! Thank you to my fantastic supervisor @tattersallg.bsky.social , my committee members @photopidge.bsky.social and @richardsmiriam1.bsky.social, and my external examiners @lizardprof.bsky.social and Dr. Toby Mündel.

Congratulations, Dr. Giacometti! I am really proud to congratulate Dr. Danilo Giacometti for his successful PhD Defence! The thesis entitled "Physiological and behavioural responses to temperature and humidity in fossorial amphibians" was defended today in front of his examining committee: Dr. Don…

Hydro Hackers: How Salamanders Outsmart “the Drying” For amphibians, water is everything. Their thin skin makes them especially vulnerable to drying out, so staying hydrated is not just about comfort—it is about survival. But how do amphibians manage their hydration state in the face of different…

🚨 New paper! 🚨 We show that salamanders behaviourally regulate a constant vapour pressure deficit regardless of temperature, which supports the presence of a humidistat that helps regulate evaporative water loss. doi.org/10.1242/jeb.... @tattersallg.bsky.social @jexpbiol.bsky.social #herpetology

🚨New paper!🚨 In our latest paper in Oecologia, we demonstrate that fossorial (i.e., underground-dwelling) ectotherms, which are thought to experience attenuated climatic variability underground, also display seasonal adjustments in key physiological functions. doi.org/10.1007/s004...

Digging into physiology: how salamanders balance energy and water between seasons Ectotherms from highly seasonal habitats often exhibit remarkable physiological plasticity, which allows them to balanceand adjust energy and water budgets in the face of fluctuating climatic conditions. Yet,…
