In early spring, #ResearchRoundup highlights a dataset on Blue-spotted Salamanders, which begin migrating despite sub-zero body temperatures. Explore this dataset by @tattersallg.bsky.social and @giacometti.bsky.social from @brocku.ca here: doi.org/10.5683/SP3/...

Congrats, Dr! @melaniedscientist.bsky.social

A Shapiro-Wilk test of the response variable concludes very significant deviation of Normality. But residuals of linear model consistent with Normal distribution.

Visual check of the linear model with DHARMa

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

Below freezing but still moving: How salamanders stay active in winter Some salamanders begin their spring migration in the deep cold. New field research shows how they stay active without freezing.

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

In the snow, these salamanders get supercool Blue spotted salamanders have been seen walking across snow and new research suggests how they get by in the cold.

Happy to share our “supercool” interview with @npr.org about the thermal biology of blue-spotted salamanders that migrate on snow:

Supercool interview with NPR Danilo Giacometti was interviewed by NPR a couple of weeks ago about our blue-spotted salamander paper in CJZ. Check it out here: And next spring, see if you can find salamanders migrating over snow.

These small amphibians begin migrating to their breeding ponds while snow still blankets the ground and ice lingers on and in the soil.
