One size does not fit all: Monitoring faecal glucocorticoid metabolites in marsupials.

Marsupial research, conservation, and management can benefit greatly from knowledge about glucocorticoid (GC) secretion patterns because GCs influence numerous aspects of physiology and play a crucial role in regulating an animal's response to stressors. Faecal glucocorticoid metabolites (FGM) offer a non-invasive tool for tracking changes in GCs over time. To date, there are relatively few validated assays for marsupials compared with other taxa, and those that have been published generally test only one assay.

SoxE gene duplication and development of the lamprey branchial skeleton: Insights into development and evolution of the neural crest.

SoxE genes are multifunctional transcriptional regulators that play key roles in specification and differentiation of neural crest. Three members (Sox8, Sox9, Sox10) are expressed in the neural crest and are thought to modulate the expression and activity of each other. In addition to regulating the expression of other early neural crest marker genes, SoxE genes are required for development of cartilage.
