Hot And Bothered: Introduced Generalist Marine Snail Outperforms Native Specialist Under Gradual And Extreme Warming, Alysha B. Putnam, Adeline Dwyer, Danielle T. Weiss, Bethany A. Bradley, Michelle D. Staudinger, Paulette Peckol

Biological Sciences: Faculty Publications

Climate change is reshaping coastal ecosystems through gradual warming and increasingly frequent extreme heat events, potentially affecting native and introduced species differently. We experimentally compared the native marine snail Littorina obtusata, a habitat and dietary specialist, to the introduced generalist Littorina littorea under sustained warming and short-term extreme heat. We measured survival and performance metrics, including grazing, growth, and attachment strength, under short- and long-term thermal stress in air and water. L. littorea consistently outperformed L. obtusata, maintaining or increasing function under warming and exhibiting greater survival during simulated heatwaves. Conversely, L. obtusata showed performance declines and higher …

Influence Of Genetic Relationships On The Spatial Distribution Of Breeding Eastern Wild Turkeys (Meleagris Gallopavo Silvestris) In West-Central Louisiana, Rachel D. Price

LSU Master's Theses

Eastern wild turkeys (Meleagris gallopavo silvestris) have a complex social system influenced by dominance hierarchies and exhibit seasonal variation in gregarious behaviors. Previous work has examined the influence of kin relationships on interactions between same sex conspecifics and flock associations, but information on how genetic relatedness influences interactions between individuals remains lacking. We constructed a dyad-based social network using high-resolution GPS data from 179 female and 68 male wild turkeys in west-central Louisiana during the 28-day period before a females’ 1st nest initiation to quantify interaction probability based on genetic relatedness and age. Our findings suggest that …

Data For Post-Retail Application Of Chitosan Coating And Uv-C Irradiation: Effects On Strawberry Shelf Life, Microbial Quality, And Consumer Acceptance, Jonathan Kershaw

ScholarsArchive Data

Food waste is a global issue with significant environmental, economic, and human health impacts. The largest share of household and retail food waste comes from fresh produce, much of which is still edible at the time of disposal. While previous work has investigated shelf-life extension technologies applied on freshly harvested produce, almost no studies have investigated the efficacy of these treatments when applied to post-retail produce. This study investigated the effect of UV-C exposure and chitosan coating on the quality, microbial load, and visual acceptance of post-retail strawberries. Strawberries were assigned to low dose UV-C, chitosan dip, or one of …

With the popularity of space travel increasing, it is important to understand the effects of microgravity on microbial communities as alterations on bacterial interactions can occur. Staphylococcus epidermidis and Escherichia coli are bacteria that are commonly found within human microbiomes. S. epidermidis is a cocci-shaped gram-positive bacterium that is part of the human skin microbiome. However, it can gather on sites of open skin and enter the body leading to an infection. E. coli is a rod-shaped gram-negative bacterium that can be found in the human gut microbiome. The pathogenic strains of E. coli have the potential to cause harmful …

Signal And Substance: Why Methodological Sophistication Fails To Guarantee Inference, Aamir Rashid, Rizwana Rasheed Jul 2026

Signal And Substance: Why Methodological Sophistication Fails To Guarantee Inference, Aamir Rashid, Rizwana Rasheed

Publications and Research

Despite increasing analytical sophistication, empirical research in organization studies continues to suffer from fragile inference, uneven theoretical accumulation, and contested credibility. This paper seeks to explain why these problems persist by shifting attention from authors’ methodological choices to the evaluative dynamics of peer review. Adopting a conceptual and theory-analytic approach, the paper theorizes peer review as an inferential gatekeeping system. Drawing on research design, theory evaluation, and philosophy-of-science literatures, this study develops an analytical framework to examine how evaluative routines shape what constitutes empirical rigor during the review process. The analysis identifies five recurring reviewer blind spots: inferential scope inflation, …

Department of Biology Faculty Scholarship and Creative Works

Background: Mosquitoes transmit a diverse range of deadly pathogens, including dengue and Plasmodium spp., when they consume the blood of vertebrate hosts in order to nutritionally provision their eggs. However, mosquito species from multiple genera have independently evolved the ability to produce eggs without blood. The molecular and physiological processes underlying the evolution of blood-independent reproduction are largely unresolved, in part because the two most well-studied models of mosquito reproductive physiology and genetics are obligate blood feeders. Herein, we integrate life-history, genomics, and gene expression to identify physiological processes and candidate genes associated with the evolution of blood-independent reproduction in …
