Cellular principles of Xenopus appendage regeneration
… this ability, I investigated Xenopus laevis tadpoles. Tadpoles can regrow their lost tails and limbs only at specific developmental stages, allowing comparative studies to determine principles of regeneration. I first compared tail amputation responses of regeneration-competent and …

FROG DECLINES: EXPLORING CONNECTIONS AMONG CLIMATE CHANGE, IMMUNITY AND DISEASE
… amphibian immune systems. We examined immune development and function (thymus growth, antibody production and skin graft rejection) in Meadow treefrogs (Hyla pseudopuma), a declining species in the MCFP, when tadpoles developed under various water regimes. During the wet seasons of 2001-2004, …
