Evolution: How Some Fishes Can Adapt Even Under Extremly Harsh Circumstances
Cave-obligate animals are some of the most mysterious creatures on the planet with their lack of eyes and pigment. Surprisingly, the evolution of these animals is still not well understood. We examined evolutionary relationships, ancestral eye-state, and body shape variation to understand how some North American fishes have become cave-adapted. I was very fortunate to go caving and collect DNA from these amazing fishes with my co-authors. We found that these fishes invaded caves and lost eyes at least three times. We found that cave and surface fishes have different body shapes, indicating that living in caves does have an impact on how these fishes look. By examining cave-adaptive evolution, we can better understand how animals are impacted by harsh or changing environments. See the paper in Evolution.

Brown Lab Awarded NSF Grant
A major goal of evolutionary biology is to understand how all living things are related to one another (a field known as phylogenetics). To do this, we can use the sequences of thousands of different genes from all across the genomes of different species. However, analyzing these datasets can be very challenging, not only because they're big, but also because they're complicated. Genes evolve differently and offer different perspectives on evolutionary relationships. Only when we consider all of this variation together do we really understand both how species are related and what forces shape a gene's evolution. Continue Reading

Missing Link in Algal Photosynthesis Found, Offers Opportunity to Improve Crop Yields
Photosynthesis is the natural process plants and algae utilize to capture sunlight and fix carbon dioxide into energy-rich sugars that fuel growth, development, and in the case of crops, yield. Algae evolved specialized carbon dioxide concentrating mechanisms (CCM) to photosynthesize much more efficiently than plants. This week, in the journal Proceedings of the National Academy of Sciences, a team from Louisiana State University (LSU) and the University of York report a long-time unexplained step in the CCM of green algae—which is key to develop a functional CCM in food crops to boost productivity “Most crops are plagued by photorespiration, which occurs when Rubisco—the enzyme that drives photosynthesis—cannot differentiate between life-sustaining carbon dioxide and oxygen molecules that waste large amounts of the plant’s energy,” said James Moroney, the Streva Alumni Professor at LSU and member of Realizing Increased Photosynthetic Efficiency (RIPE). “Ultimately, our goal is to engineer a CCM in crops to surround Rubisco with more carbon dioxide, making it more efficient and less likely to grab oxygen molecules—a problem that is shown to worsen as temperatures rise.”.

LSU Researchers Find Clue to ‘Maternal Instinct’
Oxytocin is widely referred to as the love hormone and plays an important role in the regulation of social and maternal behavior. In recent years, the oxytocin system in the brain has received tremendous attention as key to new treatments for many mental health disorders, such as anxiety, autism spectrum disorders and postpartum depression. New research led by a biologist and his students at LSU have discovered a group of cells that are activated by oxytocin in one area of female mouse brains that are not present in the same area in male mouse brains.
“Many researchers have attempted to investigate the difference between the oxytocin system in females versus males, but no one has successfully found conclusive evidence until now. Our discovery was a big surprise,” said Ryoichi Teruyama, LSU Department of Biological Sciences associate professor, who led this study published in PLOS ONE. Read the Press Release

Esselstyn Promoted to Associate Professor
Congratulations to Dr. Esselstyn on his promotion to Associate Professor! Esselstyn is the Curator of Mammals at the Museum of Natural Science and Associate Professor in the Department of Biological Sciences at Louisiana State University. In the lab, we study island biogeography, phylogenetics, systematics, co-evolution, and community ecology. Most of our research focuses on small mammals from Southeast Asia and Africa. In general, we conduct biodiversity surveys and use genetic and morphological characters of organisms to understand how species and populations are related to each other and how they interact with their environment. Our efforts help inform how biotic and abiotic processes produce the patterns of biodiversity we see today. The species-level diversity of mammals remains poorly documented, and we devote a lot of time and money to documenting this diversity. Click here to view Dr. Esselstyn's lab website.

The Kelly Lab's Research Featured on the Cover of Molecular Ecology
Lab member and Graduate student Joanna Griffiths asks whether physiological and transcriptomic responses to acidification differ among corals from different upwelling regimes. Ocean acidification (OA), the global decrease in surface water pH from absorption of anthropogenic CO2, may put many marine taxa at risk. However, populations that experience extreme localized conditions, and are adapted to these conditions predicted in the global ocean in 2,100, may be more tolerant to future OA. By identifying locally adapted populations, researchers can examine the mechanisms used to cope with decreasing pH. Read the paper in Molecular Ecology.

We asked Misagh to tell us about his research and how he was able to keep his stress at bay while earning his two latest degrees. Read More
Being a Student Can Be Stressful. Science Can Help.
There’s no doubt about it – being a student can be stressful. From scheduling classes and waitlists, to taking exams, to waiting on grades, to lining up a summer job, to managing roommate drama, to making sure you on are track to graduation, to deciding what you will “do with your life” when you finish school, stressful events lurk in every corner. No matter how prepared you are, there’s always going to be a failed grade, a missed deadline or a miscommunication with a professor here and there.
But what is stress? Stress can be defined as a behavior or physiological change in an individual in response to a real or perceived stressor. Not all of us perceive the same stressors in the same way, however, meaning that one person may deal with a stressful event and remain happy and healthy, while another may become anxious and ill as a result.
