About this Event
Biological faculty members Jason Andras, Sarah Bacon and Renae Brodie will each discuss their current research. Pizza will be served.
Learning the steps of the host-parasite dance: Molecular genetic insights into the ecology & evolution of an invertebrate-bacterial pathosystem I’ll be discussing my research group’s efforts to understand the genetic basis of interaction between an important model parasite, the bacterium Pasteuria ramosa, and its host, the planktonic crustacean Daphnia magna.
In early pregnancy, some uterine blood vessels are hollowed out into high flow, low resistance “hoses” that keep the placenta awash in fresh maternal blood. These greatly dilated vessels are severed at birth when the placenta detaches from the uterus, creating a risk for maternal hemorrhage. In the Bacon lab we are trying to better understand the uterine healing process that seals off these blood vessels and readies the uterus for the next pregnancy.
Marine intertidal invertebrates contend with daily cycles of submergence and exposure, and as the planet warms, increases in both sea water and air temperature will impact the lives of these fringe dwellers. Rising temperatures pose an existential threat to many intertidal organisms, in part due to damages that accrue when body temperatures rise beyond the optimal range. Renae Brodie and her students are examining the energetic trade-offs made by intertidal crabs under different food and body temperature conditions to decipher crab survival strategies and predict future species ranges.
