Published: 4 April 2022
...Sandy M. Kawano; Richard W. Blob ABSTRACT Amphibious fishes and salamanders are valuable functional analogs for vertebrates that spanned the water–land transition. However, investigations of walking mechanics have focused on terrestrial salamanders and, thus, may better reflect the capabilities...

... microbiota may influence the relationship between temperature and digestion. To explore the connections between these three factors, we compared digestive performance and gut microbial community diversity and composition in red-backed salamanders housed at three experimental temperatures: 10, 15 and 20°C. We...

... in fishes. The lateral hypaxial musculature (LHM) of salamanders is less anatomically complex and therefore a good system for exploring the basic mechanics of segmented musculature. Here, we derive a mathematical model of the LHM and test our model using sonomicrometry and electromyography during steady...
