Brumation by Tom Lagasse

A winter slumber
Longing for thirst to be quenched
The reptile brain wakes

by Tom Lagasse

My wife and I were walking near a pond and didn’t know if snakes hibernated or not. After a quick check, we learned that mammals hibernate and reptiles brumate.

Indigenous Engagement

The benefits of
indigenous engagement:
Ethics and Science.

Local knowledge and an awareness of local context can be integral to conducting a variety of research. However, one thing that’s less often considered is the impact of the diversity of the research team itself.

Conservation research by Ward-Fear et al (2019) into the impact of cane toads on yellow-spotted monitor lizards in Australia has unintentionally produced evidence of the scientific benefits of collaborating with local indigenous people.

Large cane toads are spreading through tropical Australia but are fatally toxic if eaten by yellow-spotted monitor lizards. Ward-Fear et al (2016) trained lizards with smaller, non-lethal cane toads and then compared the survival rates of trained and non-trained lizards in the wild over an 18 month period. They found that trained lizards had a greater survival rate than non-trained lizards, suggesting that the training helped the lizards to avoid eating the larger toxic cane toads.

Yet their study also revealed the importance of researcher diversity. In monitoring the population of lizards over 18 months, the research team included western scientists (professional, nonindigenous ecologists) and indigenous rangers (Australian-Aboriginal Traditional Owners of the region).

The indigenous rangers saw lizards from a greater distance, in more dense vegetation, under poorer light levels, and more frequently when the lizard was stationary. Additionally, when assessing the behavioural traits of the lizards, those that were spotted by the indigenous rangers were found to be more shy. What’s more, the ranger caught lizards appeared to benefit more from the training against the toxic cane toads.

All this highlights the importance of cultural diversity within research teams and in particular shows that indigenous collaboration can be utterly crucial for conservation efforts.

Snakeskin secrets

Learning from nature:

Snakeskin secrets revealing

lessons in friction.

 

The natural world has inspired engineering and design in countless ways. Now researchers are looking at snakeskins in an attempt to better understand an understudied engineering area: friction.

Abdel-Aal (2018) summarises findings from 40 species of snake to understand how the textural traits of snake skin compare to the standard features of textured industrial surfaces. This exploratory framework could subsequently lead to new, nature-inspired smart surfaces.

Frozen anoles

Frozen anoles

must evolve cold tolerance…

and flipping quickly!

 

Evolutionary changes can occur quicker than you might think. A severe cold snap in the winter of 2013-2014 led green anole lizards to develop an increased cold tolerance as measured by a loss of coordination when flipped over. Further investigation of the populations revealed changes at six genomic regions that are known to be important for regulation of function in the cold. Campbell-Staton et al, 2017.

Evolution doesn’t always have to take place over long periods of time. Recent research has shown that some lizards on Brazilian man-made islands have developed larger heads than their mainland counterparts in only 15 years. Eloy de Amorim et al, 2017.
