Lagging Brain Gene Expression Patterns Of Drosophila Melanogaster Young Adult Males Confound Comparisons Between Sexes, Flannery Mclamb, Zuying Feng, Jeanne P. Vu, Lindsey Griffin, Miguel F. Vasquez, Goran Bozinovic

Center for Life in Extreme Environments Publications

Many species, including fruit flies (Drosophila melanogaster), are sexually dimorphic. Phenotypic variation in morphology, physiology, and behavior can affect development, reproduction, health, and aging. Therefore, designating sex as a variable and sex-blocking should be considered when designing experiments. The brain regulates phenotypes throughout the lifespan by balancing survival and reproduction, and sex-specific development at each life stage is likely. Changes in morphology and physiology are governed by differential gene expression, a quantifiable molecular marker for age- and sex-specific variations. We assessed the fruit fly brain transcriptome at three adult ages for gene expression signatures of sex, age, and sex-by-age: 6698 …

Evolution Of Mate Guarding Intensity In Crickets As A Possible Adaptation To Sexual Conflict Over Sperm Transfer, Bert Foquet, Jack Thomas Mckermitt, John Hunt, Ben M. Sadd, Scott K. Sakaluk

Faculty Publications – Biological Sciences

Mate guarding is a common behavioral adaptation in males to ensure mating or to hinder current partners from remating with rival males. In the decorated cricket, Gryllodes sigillatus, males transfer a spermatophore to females at mating, comprising a sperm-containing ampulla enveloped in a large gelatinous mass, the spermatophylax, that serves as a nuptial food gift for the female. Males guard the female while she feeds on the nuptial gift and while sperm are evacuated from the ampulla into her reproductive tract. Mate guarding behavior functions to prevent competitors from mating with the female but may also represent a behavioral …

Edge Feathering Across Forest-Meadow Ecotones Increases Light Heterogeneity And Understory Plant Diversity, Aruni Kadawatha, Jean H. Burns

Faculty Scholarship

Ecotones, the transitional zones between distinct habitats, are vital for ecosystem functioning and habitat diversity. Traditional management practices frequently create abrupt boundaries, leading to stressful conditions for organisms. To address this challenge, an underutilized land management technique called “edge feathering”, which involves gradual thinning of the canopy along the forest edge, has been introduced. This study, con- ducted at Holden Arboretum in Kirtland, Ohio, investigated the effects of edge feathering on light availability and understory plant diversity in edge feathered and control treatments. We calculated the coefficient of variation in light availability as light heterogeneity and plant diversity indices at …

Leveraging Arginine Catabolism To Treat Metabolic Complications, Yiming Zhang

Arts & Sciences Graduate Student Theses and Dissertations

Fasting and caloric restriction are effective to treat patients with pre-diabetes or metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), but intensive lifestyle changes are difficult for many to implement and sustain. Therefore, by identifying and studying fasting-mediated signals, we hope to elicit and convey the therapeutic effects of fasting against MASLD without actual physiological fasting. We discovered a key pathway in the liver through unbiased transcriptomic screening in fasted mice, a novel glucose fasting-activated effector: the amino acid hydrolase, arginase 2 (ARG2). Our previously published data demonstrates that forced hepatocyte-specific Arg2 overexpression is …
