Embryonic development
- Characterizing the timing of yolk testosterone metabolism and the effects of etiocholanolone on development in avian eggs
Summary: Maternally derived steroids are metabolized during incubation. Here, we determine the timing of this embryonic metabolism for testosterone and assess early effects of metabolites on embryonic growth.
- Embryonic growth rate affects telomere attrition: an experiment in a wild bird
Highlighted Article: Faster embryonic growth rate, manipulated using incubation temperature, results in shorter telomere length at hatching in a wild bird species, the common tern.
- Thermal spikes from the urban heat island increase mortality and alter physiology of lizard embryos
Summary: Nest temperatures in the urban landscape increase embryo developmental rate but reduce egg survival in lizards.
- Tropical flatback turtle (Natator depressus) embryos are resilient to the heat of climate change
Summary: Flatback sea turtles nesting in tropical regions can withstand high-temperature incubation.
- Consequences of calcium decline on the embryogenesis and life history of Daphnia magna
Summary: Ambient calcium is declining in thousands of soft-water lake habitats. Daphnia females provision their offspring with calcium and through that incur a potential allocation trade-off.
