Time lapse of wood frog development (Rana sylvatica)
Early salamander cleavage (Ambystoma maculatum)
Ambystoma maculatum - stage 40
This is a promotional video put out by the college following our recent Gordon and Betty Moore Foundation grant. The project is in collaboration with researchers at Stony Brook (David Matus), Columbia (Solange Duhamel) and the AMNH (John Burns). We won't be working too much on disease. Instead the focus is on cell biology and imaging over the next three years.

"Discovery of FIRST tadpoles of the LAST frog family for which tadpoles were unknown: These tadpoles are completely fossorial...they live under sand and gravel beds...their eel-like bodies permit movement under sand... skin cover protects their eyes.... and sand mixed with sediments in their guts provides nourishment. When metamorphosis is complete they emerge out of sand which served as their nursery and grow into adults that dance on rocks in streams to attract mates. For the first time, we have discovered the unique tadpoles of Indian Dancing frogs. Our findings are published in the journal PLoS One."
This episode of Shelf Life from the American Museum of Natural History was masterfully produced by the talented Erin Graham and features our
NSF-funded research on an algal symbiosis with salamander embryos.
This animation highlights some of the dramatic changes to the skull during the metamorphosis of a cartilaginous (blue)
tadpole skull into the skull of an adult frog, which is mostly made of bone (red).
This time lapse was taken by Roger Hangarter from Indiana University for our 2011 paper on a salamander-algal symbiosis.
This time lapse was taken through a dissecting scope. It includes images from an SEM study of direct development in Eleutherodactylus coqui by Moury and Hanken (1995).
This is a micro CT image stack taken at Harvard University's Center for Nanoscale Systems with Joanna Larson and Hendrik Mueller.
It shows a series of profile images revealing the internal anatomy of a Plethodon cinereus embryo (eastern red backed salamander). The soft tissues were stained overnight with phosphomolybdic acid.
