Prior work revealed that <i>Astyanax</i> cave-dwelling morphs derived from different cave localities express significantly higher levels of blood hemoglobin compared to surface-dwelling fish. Interestingly, this elevation is maintained in different populations of cavefish, despite captive rearing in normal oxygen conditions. We capitalized on the consistent response of elevated hemoglobin in captive cavefish, which were derived from geographically distinct regions, to determine if this elevation is underpinned by expression of the same <i>Hb</i> genes. Blood hemoglobin proteins are encoded by a large family of <i>hemoglobin</i> (<i>Hb</i>) gene family members, which demonstrate coordinated expression patterns, subject to various organismal (e.g., period of life history) and environmental influences (e.g., oxygen availability). Surprisingly, we found that geographically distinct populations showed mostly divergent patterns of <i>Hb</i> gene expression. Cavefish from two cave localities, Pachón and Tinaja, have a more recent shared origin, and show more similar <i>Hb</i> expression patterns as adults. However, during embryonic phases, Pachón and Tinaja show significant variability in timing of peak expression of <i>Hb</i> family members. In sum, the transcriptomic underpinnings of <i>Hb</i> gene expression represents a complex composite of shared and divergent expression patterns across three captive cavefish populations.

I was obsessed with Disney's Dinosaur movie as a toddler, and grew up catching bugs, watching tons of Animal Planet, and interacting closely with the urban wildlife around me. When I was in middle school, I remember being amazed by a nature documentary explaining how a population of brown bears that ventured into the Arctic accumulated incrementally beneficial mutations over thousands of generations to evolve into polar bears—I think that was the moment that got me to really understand a bit of how evolution works, and I've enjoyed understanding the processes that lead to natural diversity ever since.&lt;/p&gt;&lt;p&gt;I moved to the United States for college and was lucky to work on two (broadly speaking) evolutionary projects as an undergrad, one with a geneticist and another with a statistician. In my senior year, I took a course in developmental biology since I started recognizing it as the bridge between evolution and genetics. And even when I was a research assistant after college in a lab developing neurogenomic technologies, I found myself drawn to the molecular biology of quirky organisms—I remember reading about the genome of the scaly-foot snail (which can grow iron-mineralized scales!) and would chat with labmates about the molecular basis of temperature-dependent sex determination. I think that it was around then that I realized the type of biologist I want to be is one who can integrate evolutionary, developmental, and genomic lines of inquiry to better understand organisms and their biology.&lt;/p&gt;&lt;p&gt;My graduate program is in Molecular Biology, and I came to Princeton without a specific lab in mind—the program requires students to do three rotations as first years to decide which lab to join for their thesis work. Since I had enjoyed developing a sequencing-based technology during my post-bac, the first two labs I rotated in were CRISPR-based technology development labs. On a whim, I decided to join the Mallarino lab for my last rotation, to be able to study a novel biological system. Pretty soon, I realized that I enjoyed my interactions with labmates, many of whom, like me, were passionate about biodiversity, and were excited to use cutting-edge technologies to better understand it. It is this shared passion and the community in the lab that initially drew me to EvoDevo work for my PhD.&lt;/p&gt;&lt;p&gt;For me, I think the three are intertwined. I enjoy using novel technologies to better understand biological systems, and information-rich datasets can help generate new questions. I also really enjoy working with understudied organisms, using technology to shed light on their biology and how it differs from more traditional models.

Based on these data, we analyzed clusters of differentially expressed genes for enriched pathways and biological processes that may be involved in polypide budding, growth, active functioning, and degradation. Although stem cells have never been described in Bryozoa, our analysis revealed the expression of conservative “stemness” markers in developing buds and juvenile polypides.

The self-fertilising nematode <i>Pristionchus pacificus</i> has been developed as a genetic model system for studying developmental plasticity due to its mouth-form polyphenism that results in alternative feeding strategies with a facultative predatory and non-predatory mouth form. Many studies linked molecular aspects of the regulation of mouth-form polyphenism with investigations of its evolutionary and ecological significance. Also, several environmental factors influencing <i>P. pacificus</i> feeding structure expression were identified including temperature, culture condition and population density. However, the nutritional plasticity of the mouth form has never been properly investigated although polyphenisms are known to be influenced by changes in nutritional conditions. For instance, studies in eusocial insects and scarab beetles have provided significant mechanistic insights into the nutritional regulation of polyphenisms but also other forms of plasticity. Here, we study the influence of nutrition on mouth-form polyphenism in <i>P. pacificus</i> through experiments with monosaccharide and fatty acid supplementation. We show that in particular glucose supplementation renders worms non-predatory. Subsequent transcriptomic and mutant analyses indicate that <i>de novo</i> fatty acid synthesis and peroxisomal beta-oxidation pathways play an important role in the mediation of this plastic response.

We also report two conspicuous notches in the R. spinulosa frontoparietal bone mineralization front which are absent in X. tropicalis, and presumably represent evolutionary remnants of the coronal suture that separates the frontal and parietal bones in most vertebrates. As such notches have not been overtly reported in the literature, we examined the X. tropicalis sibling species Xenopus laevis, and were able to identify similar, albeit transient, indentations in the forming frontoparietal bone, suggesting that vestigial coronal sutures might exist in more frog species than anticipated.
