Development and Evolution of Complex Reproductive Traits in the Brassicaceae and Cleomaceae
DownloadSpring 2023
Flowering plants exhibit a bewildering diversity of forms, which raises fundamental questions on how that diversity arises. A cornerstone of evolutionary developmental biology is the expansion of comparative landscapes and establishment of focal clades that enable investigation of complex and...

Gene expression and sensory structures in sponges: Explorations of sensory-neural origins in a non-bilaterian context
DownloadFall 2017
The nervous system is present in all but two animal phyla – one of them being Porifera, sponges. Sponges have no neurons and yet have organized behavior and finely tuned sensation. Furthermore, sponges have genes involved in the nervous system of other animals (informally called ‘neural’ genes)....

Responses to lowered salinity in the Pacific spiny dogfish, Squalus suckleyi, a marginally euryhaline shark
DownloadFall 2018
Euryhalinity is the ability to survive in multiple environmental salinities. Full euryhalinity is rare within the elasmobranchs (rays, skates, and sharks), however, marginal euryhalinity is comparatively more common. The physiology underlying these adaptations is relatively understudied in...
