Lungless salamanders (Plethodontidae) are often active on the surface on rainy evenings, and some species may even climb vegetation in search of prey. Here I report the first investigation of plant climbing in the Northern Two-lined Salamander (Eurycea bislineata). Surveys were carried out along Bat Lake Creek in Algonquin Provincial Park over four rainy nights in summer 2007 for Northern Two-lined Salamanders. I compared the numbers of Northern Two-lined Salamanders foraging on the ground with those climbing on plants, and over half of the Northern Two-lined Salamanders were climbing plants. This behaviour may provide the Northern Two-lined Salamander with access to an underutilized food source, and plants may represent an additional foraging habitat for this species.

The metamorphosis of the epibranchial cartilage, a skeletal component of the hyobranchial apparatus, in the salamander Eurycea bislineata entails a combination of the reabsorption of a larval cartilaginous element with the simultaneous genesis of an adult cartilage in the same place. In this study we focus on the fate of the larval chondrocytes. Two hypotheses are considered: one, larval cells simply die off during metamorphosis, or, alternatively, they dedifferentiate and participate in the formation of the adult element. Thyroxine treatment and experimental tissue manipulation coupled with measurements of thyroxine levels using radioimmunoassay show that, within 24 h after T4 treatment, larval chondrocytes in the epibranchials exhibit large autophagocytic vacuoles, disruption of the rough endoplasmic reticulum, abnormally shaped mitochondria, abundance of lysosomes and nuclear degeneration, all symptoms of the onset of cell death. In conclusion, evidence from light microscopy, TEM and SEM show that the larval chondrocytes in response to rising levels of thyroid hormones undergo a process of lysosomal autophagocytosis and do not participate in the formation of adult structures.
