Climate change is something that we are all worried about. But as scientific researchers, linking fields as disparate in focus as evolutionary development and global change is quite a challenge. Dr. Yui Suzuki from Wellesley College is helping to pioneer this interdisciplinary research area by exploring how climate change may shape insect evolution and development. The UMD Department of Entomology hosted Dr. Suzuki for a talk on his research as well as a talk on his experience as a liberal arts professor on August 30, 2024. written by: Ben Gregory
Compare the ears of these two species of rabbits: the Eastern cottontail rabbit (left), native to the temperate forests of the eastern United States; an6d the black-tailed jackrabbit (right), which lives in the deserts of the Western US and Mexico. The jackrabbit has much larger ears relative to the size of its body. Evolutionary biologists think that this species’ large ears may be an adaptation to deal with high temperatures. Rabbits living in the desert face a much higher risk of overheating than rabbits living in the much cooler forests on the east coast. Larger ears allow for more surface area for the rabbits to dissipate heat into the air far from their high-temperature core. Natural selection on rabbits in these very hot environments favored rabbits with larger ears because rabbits with smaller ears were more likely to experience the negative consequences of overheating. Over many generations, this continued pressure led to rabbits with larger and larger ears, while rabbits on the east coast did not experience this pressure, and so did not gain this trait. The closest to retirement Emeritus Professor Mike Raupp has gotten is "almost" retired. The 'Bug Guy' shares with The Silver Terp the range of activities he has been up to from cicada-mania to plans for a critter filled study abroad and everything in between.

By Lasair ní Chochlain and Eva Perry Urban trees provide important habitats for insects and other arthropods. Dr. Paola Olaya-Arenas, an adjunct professor at Universidad Icesi, presented the results of her research on Bogotá’s urban trees and associated insect communities to the University of Maryland’s Department of Entomology this April. Dr. Olaya-Arenas and collaborators sampled insects associated with Ficus americana Aubl. located in parks and on sidewalks in three urban areas in Bogotá, Colombia. A diverse and abundant community of herbivores, predators, and parasitoids was sampled, and information about their feeding habits, other host trees, and damage to plant tissue is described in Dr. Olaya-Arenas et al., 2022 bilingual publication “Insects associated with urban trees in Bogotá (Colombia): exploring their diversity and function.” This publication can be downloaded from the following link (Electronic book link), and it is a good guide for citizens and visitors of the city. Dr. Sara Via's webinar series, "Climate & Biodiversity Action", has begun! Next talk, "Regenerating our soil," is Wednesday, June 19, 2024, 4-5:30 pm. Tune in to find out what healthy soil is and how we can get it back.
Can't wait till June for expert advice on climate change?! Want to do something now but not sure what?

On any given day, Dr. Tanisha Williams might be found exploring the desert in search of bush tomatoes, analyzing historical herbarium samples, or nurturing a vibrant community of Black botanists. What underscores all her work is the elevation and exploration of the relationships between people and plants, especially in the context of human mediated climate change caused by anthropogenic greenhouse gases (IPCC, 2013). In her work, Dr. Williams investigated how this change is affecting the phenology and diversity of plants, particularly in the context of climate change and Traditional Ecological Knowledge (TEK). written by: Ben Gregory and Minh Le
Vampires do exist – they’re just tiny and have six legs. Blood-feeding insects, such as mosquitoes, feed on the blood of other animals to complete their life cycle. Blood provides many essential nutrients that aren’t easy to get elsewhere in nature. Unfortunately for us, blood-feeding insects can carry pathogens that cause human diseases, like malaria, West Nile, and Zika. For this reason, many scientists are interested in learning how the process of blood feeding works, and what we might be able to do to keep ourselves safe from it. One of these scientists, Dr. Chloé Lahondère of the Department of Biochemistry at Virginia Tech, has spent years learning about one unusual element of blood-feeding that you probably haven’t considered: how to stay cool. Your blood is hot – about 100°F in your body! Given that insects are cold-blooded animals and must maintain their body temperature below a certain level, the question arises “how does a blood-feeder feed on piping hot blood without overheating? Dr. Lahondère is using the kissing bug (Figure 1, Left) to answer this question. We are thrilled to extend a big CONGRATULATIONS to Samantha Rosa, for being selected to join the esteemed cohort of NOAA’s Margaret A. Davidson Graduate Fellows! Samantha Rosa is a graduate student in the Gruner and Espíndola Labs. As part of the fellowship Samantha will conduct collaborative research with the Heʻeia National Estuarine Research Reserve in Ka-waha-o-ka-manō on the island of O‘ahu. Her research will focus on developing K-12 Community-Driven Science curriculum and programming that draws on Indigenous and contemporary knowledge to empower children and educators to lead biocultural restoration and management of Hawai‘i's cultural and ecological systems. Samantha is excited to contribute her experience as a classroom teacher and ecologist towards enhancing the education programs at the only NOAA reserve formally recognized as an Indigenous and community-conserved area. Dr. Karen Rane has been the Director of the University of Maryland’s Plant Diagnostic Lab (PDL) since 2007. After 17 years of service and a WOW # of plant samples processed, she has decided to turn in the towel and retire this semester. We thank Karen for lending her expertise to our Departments, the University and broader community and wish her all the best in retirement. For more on Karen and her service check out the write up from her National Plant Diagnostic Network (NPDN) - Lifetime Achievement Award and recent(ish) graduate student blog about her work, "Catching bugs isn’t just for entomologists: Inside the University of Maryland’s plant diagnostic lab"

written by: Allison Huysman, Leo Kerner and Ben Burgunder It is a dry day in the Montana rangelands, a vast landscape of sagebrush, prairie junegrass, and purple prairie clover. Dr. Kathryn Bloodworth is vacuuming the plants. She wields a modified leaf blower designed to suck up the insects that call this wide-open space home (Fig. 1). Her goal: to understand the links between insects, grassland plant communities, and drought. Shout out to Entomology Ph.D. student Megan Ma (Shultz Lab & Wood Lab at Smithsonian NMNH) for receiving the prestigious National Science Foundation (NSF) Graduate Research Fellowship, which recognizes outstanding graduate students in science, technology, engineering, and mathematics (STEM).
Insect Terps in Fritz Lab collaborate with NC State University on genomic approach to identify signs of emerging pesticide resistance. From AGNR press release: “Global food security and protection of public health rely on the availability of effective strategies to manage pests, but as it currently stands, the evolution of resistance across many pests of agricultural and public health importance is outpacing the rate at which we can discover new technologies to manage them,” said Megan Fritz, an associate professor of entomology at UMD and senior author of the study. “I'm really excited about this study, because we're developing the framework for use of genomic approaches to monitor and manage resistance in any system.” Check out full AGNR press release here>>
Share your colleagues exciting work on social media (X , facebook) or wherever & however you like to spread science. "Legacy effects of long-term autumn leaf litter removal slow decomposition rates and reduce soil carbon in suburban yards," out in the journal Plants, People, Planet, is one of Burghardt Labs latest pubs. Their study finds that in places where people historically have left their fallen leaves to decompose, without removing them, the soil holds up to 32% more carbon on average. Check out AGNR's press release here. Includes quotes by Max Ferlauto and suggests some ways one can adopt leaf leaving practices in the landscapes they manage.

[Seminar Blog] Designing and managing agricultural landscapes for insect driven ecosystem services4/2/2024
written by: Brendan Randall & Angela Saenz A brisk, foggy morning; the sun rises on a midwest farm. Corn stalks sway for as far as the eye can see, seemingly the only life around. If one looks carefully, however, one will find the farm is teeming with life. Dr. Nate Haan is fascinated by the diversity of organisms on farms and how we can understand their ecology to improve farm sustainability and conservation of native biodiversity. Now an assistant professor in the Entomology Department at the University of Kentucky (UK), he is excited to answer fundamental questions about how farm management practices affect insects. In his seminar talk, Dr. Haan presented various approaches to test his central research question–does management affect insects in agricultural landscapes? Katy Evans (Espindola Lab) has been awarded the esteemed Ann G. Wylie Dissertation Fellowship by the University of Maryland’s Graduate School! Awarded to students in the final stages of their doctorate (wow, Katy, getting close!), the Wylie Fellowship provides one semester of support during the 2024-2025 academic year. Katy's dissertation research aims to understand plant-insect interactions and their movements in rapidly changing landscapes, and consequential effects on plant reproduction. She uses experimental and observational data to investigate the effects of floral diversity on beneficial arthropods, and its repercussions on nearby plant fitness and reproductive success. Please join us in giving Katy a round of applause for this well-deserved recognition! Harriet Harris, an undergrad pursuing a minor and honors in ento w/ Dr. vanEngelsdorp, shines in Maryland Today. In addition to being an accomplished student and kick-butt roller derby player, Harriet is co-founder of BaltiSpore, a company that markets "functional" mushroom products for various health benefits.
