​The end of the semester is here! For the last weekly seminar series, the Entomology Department welcomed Dr. Jason Rasgon to speak about his research and experience with new molecular tools for gene editing in arthropods. Dr. Rasgon completed his Ph.D. at the Entomology Department of the University of California, Davis. There he had the opportunity to conduct research on Wolbachia infection dynamics, a naturally occurring bacteria that lives within several insect taxa and is passed from one generation to the next through their eggs. Since early in his career, he has successfully answered research questions in various systems, which has given him the experience to lead projects across a wide range of biology-subdisciplines. Currently, he is a professor of Entomology and Disease Epidemiology at Pennsylvania State University, where he integrates population biology, ecology, molecular tools, and theory to answer both fundamental and applied questions in genetics. The main goal of Dr. Rasgon’s lab is the development of new methods that can be used to introduce transgenes into natural disease vector populations.

Please join us in congratulating Dr. Karen Rane, Director of UMD’s Plant Diagnostic Lab, for being named recipient of the National Plant Diagnostic Network’s (NPDN) Lifetime Achievement Award.

Quote from NPDN announcement:
“Since the beginning, NPDN has benefited from Rane’s practical experience and advice, whether it was in developing training tools, setting priorities or mentoring new diagnosticians.”

​Let’s face it. Graduate school can be a wonderful experience, but there are stressors aplenty - from financial worry to time management, coping with expectations of yourself and others, all in a field of scientific research - where the nature of the work involves a high degree of uncertainty and uncharted territory1, 2. These cumulative pressures can all lead to a great deal of stress for the graduate student, especially during the COVID-19 pandemic. Thankfully, skilled and caring professionals like Ms. Simone Warrick-Bell are there if needed. Ms. Warrick-Bell has been a graduate student academic counselor for the University of Maryland (UMD) Graduate School since early 2020, and prior to 2020 she was a care manager with the UMD counseling center. She holds a Master’s in Counseling Psychology and is a licensed Clinical Professional Counselor. Her works include individual consultation sessions and leading graduate student circle sessions, which were created solely to support UMD graduate students. The entomology department was happy to welcome Ms. Warrick-Bell to our Friday seminar series and to hear more about the services she provides through the Graduate School.

The natural world is teeming with gorgeous and awe-inspiring biological structures, patterns, and colors that cannot be described via mere words alone. During the digital age, accurate and realistic imagery of these specimens can be obtained through the lens of a camera. However, the camera can only capture what is, not what could have been. Exquisite imagery requires the gentle and imaginative hand of an artist like Taina R. Litwak a scientific illustrator with the US Department of Agriculture’s Systematic Entomology Lab and the Smithsonian Institution’s Museum of Natural History who joins this week’s entomology colloquium at the University of Maryland to talk about entomological art in the digital age. ​

​Combining different schools of thought or discipline can lead to more meaningful discovery and understanding. The work of Dr. Chris Hamilton addresses this by studying Aphonopelma, a group of tarantulas that are found in the incredible and unique biome of sky islands in the southwestern United States and Mexico. This group of tarantulas are important as a marker for understanding the region, and hold a place of cultural significance in the San Carlos Apache creation story. What is a sky island you ask? They are made of mountain ranges that are surrounded by desert valleys. These mountains create interesting temperature and humidity gradients that play host to various stratified environments. These environments are similar to ocean islands because the deserts take the role of the impassable ocean, isolating organisms to specific islands if they can not cross the desert. The tarantulas in this area have no way to cross the large deserts and are partitioned into their niches across this area. The speciation and diversity of these tarantulas can shed light on the geologic history, evolution, and current state of this understudied diversity hot spot.
