How can we bring together the study of genes, embryos and fossils? Embryos in Deep Time is a critical synthesis of the study of individual development in fossils. It brings together an up-to-date review of concepts from comparative anatomy, ecology and developmental genetics, an…
"Can fossil embryos demonstrate evolutionary changes in reproductive modes? How have changes in ocean chemistry in the past affected the development of marine organisms? What can the microstructure of fossil bone and teeth reveal about maturation time, longevity, and changes in …

Focusing on specific pathways or pathway components, Analysis of Growth Factor Signaling in Embryos provides the methods and guidelines for experimental design to study cell signaling in vertebrate embryos. With contributions from top researchers, the book incorporates molecular…
The Blackside Dace (Chrosomus cumberlandensis; BSD) is a federally threatened minnow that has been extirpated from 31 streams in Tennessee and Kentucky since 1978. Although there is strong evidence linking elevated conductivity levels and low BSD occurrence, the mechanistic rela…
We studied the responses of the late-stage chicken embryo to infection with the lymphotropic viruses Marek's disease virus (MDV 1), turkey herpesvirus (MDV 3), and infectious bursal disease virus (IBDV). Our objective was to examine the effects of these viruses on embryonic lymp…
To gain insight into how the age of the hen affects selected reproductive characteristics and subsequent embryonic and posthatching development, experiments were conducted to study: (1) hormonal and initial egg production characteristics as influenced by hen age and age at photo…
