Evolutionary Genetics of Dictyostelids: Cryptic Species, Sociality and Sex
… serves as an ideal system to study social evolution because of the social stage of its lifecycle, where individuals aggregate to build a multicellular structure. However, much of its basic biology remains unknown and this limits its utility. I used three separate projects to fill these …

Cooperation, conflict, and experimental evolution in social amoebae
… the importance of high relatedness in the evolution of cooperation and cheater resistance. In an experimental evolution study, we tested the hypothesis that de novo cheater mutants readily evolve under low relatedness conditions. We found that the majority of our lines evolved to cheat …

Intertwined evolution of swimming, morphology and microhabitat in tree frogs from the subfamily Hylinae
… those three approaches we aim to disentangle the evolution of morphological traits and their influence on swimming behavior and performance, both within multiple microhabitats for Neotropical tree frogs. The subfamily Hylinae includes 163 species; they have three main locomotion modes with a …

The zebrafish maternal factor pollywog is required for yolk syncytial layer morphogenesis
… undergoes dramatic reorganization during early development through processes that mirror the morphogenetic movements of the blastoderm. The YSL and YSL nuclei (YSN) undergo epiboly, and during convergence and extension movements of the blastoderm, the YSN underneath the animal cap also converge …
