Determination Of A New Spring-Flying Species Of The Pterourus Glaucus Complex (Papilionidae) In Southern New England, Harry Pavulaan
Determination Of A New Spring-Flying Species Of The Pterourus Glaucus Complex (Papilionidae) In Southern New England, Harry Pavulaan
The Taxonomic Report of the International Lepidoptera Survey
The Pterourus glaucus complex in three southern New England states is analyzed for cryptic speciation. What was historically considered to be one species, P. glaucus (Linnaeus, 1758), was recently split to separate P. canadensis (Rothschild & Jordan, 1906) at species rank (Hagen et al., 1991). Additionally, P. appalachiensis Pavulaan & Wright, 2002, was described as an Appalachian Mountain endemic. The western member of the complex, P. rutulus (Lucas, 1852), has frequently been considered a subspecies of P. glaucus (Scott, 1986; Tyler, Brown & Wilson, 1994), as was P. alexiares (Höpffer, 1866) (Tyler, Brown & …

Identifying Invasive Species Sightings From Geoai-Validated Social Media Posts, Nathan Fox, Derek Van Berkel
I-GUIDE Forum
The spread of invasive species requires scalable monitoring techniques to help guide management and conservation strategies. Here, we explore the potential of GeoAI for the rapid validation of invasive species sightings through social media data. We utilized the Flickr API to retrieve 23,000 images from posts that contained the names of 72 invasive species across various taxonomic categories within the contiguous USA. Then using BioCLIP, a computer vision model capable of identifying over 450,000 species, we assessed whether these posts genuinely contained the species that the user tagged. Results varied, with some species like the European Starling showing high match …
Working In Pairs Increases Consistency Of Georgia Adopt-A-Stream's Habitat Assessment, Christopher H. Kodani, Robert Bourne, Cody Jones, Michael Kahle, Cecilia Nachtmann
Working In Pairs Increases Consistency Of Georgia Adopt-A-Stream's Habitat Assessment, Christopher H. Kodani, Robert Bourne, Cody Jones, Michael Kahle, Cecilia Nachtmann
Georgia Journal of Science
Habitat assessment is a skill that is important to stream ecologists of all levels, including volunteers of water quality monitoring programs such as Georgia Adopt-A-Stream (AAS). Some aspects of habitat assessment can be subjective because observers must use their best judgement in assessing some variables, therefore, it is worthwhile to examine the variation in volunteer stream monitor observations, the effect of training, and the reliability of habitat metrics calculated from the data collected. To gain some insight, we asked volunteers attending a workshop at AAS’s 2022 Confluence Conference to complete a Habitat Assessment Worksheet both before and after a short …

Mutations And Antibiotic Resistance In Mycobacterium Tuberculosis, Ryan M. Johnson, Bodhi Brady, Nicklaus Busse, Connor Beckman, Hunter Gloden, Joseph Glasrud, Zachary Smith, Hari P. Nepal, Madhav P. Nepal
Life Science Reports
Mycobacterium tuberculosis (MTB) is a bacterium known to target, infect, and destroy lung cells as well as connective tissues within the body. This bacterium is prevalent worldwide and has infected over a quarter of the current world population, becoming one of the most successful pathogens in history. Due to its extreme transmission rates as an airborne pathogen, MTB strains have been treated with antibiotics such as rifampicin and isoniazid, which inhibit bacterial infection in the human body. These first-round drugs remained as successful mechanisms for slowing and killing the pathogen, notably through rifampicin's inhibition of RNA-polymerase and isoniazid’s ability to …

Prescription Adherence Rates Across Medication Categories, Makenzie Stagner, Allie Weber, Madhav P. Nepal, Hari P. Nepal
Life Science Reports
Prescription adherence is a major public health challenge, as non-adherence to medication instructions can lead to poorer health outcomes and higher healthcare costs. Although prescription adherence is crucial for managing patient compliance and health outcomes, adherence rates differ greatly between medication types. The main objectives of this study were to determine prescription adherence rates across six medication types (antibiotic, cardiac, chronic health, pediatric, and psychiatric) and identify sources of variation. We searched PubMed and Web of Science databases for relevant published articles. Previous research data were selected related to prescription adherences and compliance rates were included in our analysis. Results …

PANDION: The Osprey Journal of Research and Ideas
Artist Statement
The Moon Jelly is a piece I created as a part of the Scientific Illustration course I participated in during the summer semester of 2023. This piece was inspired by the livestreams of the Monterey Bay Aquarium that film these moon jellies (Aurelia aurita) in their tank. The Moon Jelly is an ink drawing created as part of a collection focused on Monterey Bay Aquarium animals. Through this artwork I hoped to draw attention to smaller marine animals that may otherwise be overlooked even though they provide a vital role in the ecosystem. Moon jellyfish are important marine …
Clustered Setation On The Pedipalps Of Buthid Scorpions (Scorpiones: Buthidae), Graeme Lowe, Victoria Tang
Clustered Setation On The Pedipalps Of Buthid Scorpions (Scorpiones: Buthidae), Graeme Lowe, Victoria Tang
Euscorpius
Chaetotaxy of the external pedipalp femur and distal ventral pedipalp movable finger was studied in 120 species, 69 genera and 17 families of scorpions. Setation was generally denser in the ‘Buthus’ group, a major arid-adapted buthid lineage distributed across Palearctic deserts. On the external femur, macrosetae formed a prominent cluster, the ‘distal external macrosetal cluster’ (DEMC); on the distal ventral movable finger they formed a dense patch, the ‘distal ventral macrosetal cluster’ (DVMC). In other buthids and non-buthids, the DEMC and DVMC were mostly absent, except in a few arid-adapted genera. Relative setation densities of DEMC and DVMC in different …

Fire And Ant Interactions Mediated By Honeydew And Extrafloral Nectar In An Australian Tropical Savanna, Fernanda M. P. Oliveira, Carlos H. F Silva, Melinda L. Moir, Inara R. Leal, Alan N. Andersen
Natural Resources Research Articles
Fire is a major disturbance affecting ecosystems globally, but its impact on mutualisms has received minimal attention. Here, we use a long-term field experiment to investigate the impact of different fire regimes on globally important ant–honeydew and ant–extrafloral nectar (EFN) mutualistic interactions in an Australian tropical savanna. These interactions provide ants with a key energy source, while their plant and hemipteran hosts receive protection services. We examined ant interactions on species of Eucalyptus (lacking EFNs) and Acacia (with EFNs) in three replicate plots each of burning every 2 and 3 years early in the dry season, burning late in the …

Temperature Affects Nest Box Selection, Nest Success, And Nestling Size In A Southeastern Population Of Eastern Bluebirds, Katie Stumpf
Temperature Affects Nest Box Selection, Nest Success, And Nestling Size In A Southeastern Population Of Eastern Bluebirds, Katie Stumpf
Georgia Journal of Science
Given the critical role of temperature in avian reproduction, rising global temperatures will likely impact reproductive success of many bird populations. We examined the effect of nest box temperature, nest box color, entrance orientation, distance to forest cover, and distance to water on net box selection, nest success, and nestling size in eastern bluebirds (Sialia sialis) in central Georgia. White painted nest boxes had significantly cooler temperatures than control nest boxes (P < 0.05). However, model selection revealed that eastern bluebird females selected control boxes, despite their overall warmer temperatures. Nest success was associated with year, likely because of high nest predation during the warmer 2022 breeding season (P < 0.05). Nest success was also associated with cooler nest boxes, possibly because incubating females spend more time incubating which can reduce predation risks. Larger nestlings fledged from painted nest boxes, nest boxes with cooler temperatures, and nests from 2021, which we attribute to decreased thermoregulatory demands enabling faster nestling growth in cooler boxes and years. These seemingly opposing results suggest there may be an optimal temperature range where nest box temperature maximizes reproductive fitness while minimizing energetic demands on incubating adults. Determining this temperature range can help target management efforts to ensure specific goals are met.
Albinism In Olivierus Martensii (Karsch, 1879) (Scorpiones: Buthidae), Victoria Tang, Zhenbang Liu
Albinism In Olivierus Martensii (Karsch, 1879) (Scorpiones: Buthidae), Victoria Tang, Zhenbang Liu
Euscorpius
This is a formal case report for the albinism in Olivierus martensii (Karsch, 1879). Albino phenotype is compared with its normal counterpart in terms of their morphology and behavior by cursory experiments. The examined 7 albino individuals (5 of which were adults) were smaller and more slender than their normal counterparts. However, these quantitative differences were not statistically significant and should be treated with caution due to the low sample size. Their abilities to detect both white light and UV light or UV-excited fluorescence were not significantly undermined, although their tendency to ensure a clear vision through self-cleaning behavior appeared …

Resource Selection Of The Southern Fox Squirrel (Sciurus Niger Niger) In The Coastal Plain Of Virginia, Marissa H. Guill, Jesse L. De La Cruz, K. Marc Puckett, W. Mark Ford
Virginia Journal of Science
The southern fox squirrel (Sciurus niger niger) is a subspecies of fox squirrel that ranges from southeastern Virginia to northern Florida. Throughout its Southeastern range, southern fox squirrel habitat of natural mixed pine-hardwood forests has been fragmented by agriculture and short-rotation pine plantations. In Virginia, remaining habitat has been transformed by fire suppression on the landscape and has in turn resulted in small, disjunct populations of southern fox squirrels. We sought to identify the home range and resource utilization of southern fox squirrels in the southern Coastal Plain of Virginia. From established nest boxes, we captured, radio collared …

Anthropology Faculty Publications and Presentations
Objectives
Cortical bone geometry is commonly used to investigate biomechanical properties of primate mandibles. However, the ontogeny of these properties is less understood. Here we investigate changes in cortical bone cross-sectional properties throughout capuchin ontogeny and compare captive versus wild, semi-provisioned groups. Tufted capuchins (Sapajus spp.) are known to consume relatively hard/tough foods, while untufted capuchins (Cebus spp.) exploit less mechanically challenging foods. Previous research indicates dietary differences are present early in development and adult Sapajus mandibles can resist higher bending/shear/torsional loads.
Materials and methods
This study utilized microCT scans of 22 Cebus and 45 Sapajus from early …

Ophidiomyces Ophidiicola And Texas Snakes: A Field To Bench Study Of Ophidiomycosis, Kenlynn L. Volz
Biology Theses
Ophidiomyces ophidiicola (Oo), the primary cause of Ophidiomycosis, is a fungal pathogen recently detected in Texas snakes. Prior to this study, there were major knowledge gaps regarding Oo growth, spread, and suitable environmental conditions. This study filled those gaps using a field to bench approach involving sampling snakes across Texas, in vitro fungal growth, and ecological niche modeling. 103 snakes were sampled across Texas in 2023 and 2024 and six cases of Oo infection were detected. Results of the growth experiment suggest that Oo prefers more stable temperatures and high humidity to a point and that there is a …

Monitoring The Seasonal Presence Of The Blue Shiner, Cyprinella Caerulea, In Little River Canyon National Preserve Using Environmental Dna, Deanna Meadows
Theses
The study of environmental DNA (eDNA) has provided researchers with a more accessible and sensitive way to identify the presence of specific species compared to traditional monitoring methods. eDNA enables species detection by analyzing environmental samples such as water or soil, which contain genetic material shed by organisms in a given area. Research indicates that eDNA techniques have become a valuable method for monitoring threatened and invasive species, proving particularly reliable for detecting aquatic species compared to traditional techniques. Quantitative PCR (qPCR) has been used in numerous eDNA studies, as it provides for greater accuracy than conventional PCR. Cyprinella …

Précis Of: "Birds, Bats And Minds: Tales Of A Revolutionary Scientist, Donald R. Griffin", Carolyn A. Ristau
Animal Sentience
Donald Griffin co-discovered bat sonar and founded the field of echolocation. He studied bird migration and founded Cognitive Ethology, the study of animal awareness and mental experiences. In all these endeavors, he faced hostile opposition. The biography (Ristau 2024) examines Griffin's life and the scientific explorations by him and others in these fields. This Précis emphasizes his arguments and supporting evidence for animal consciousness as well as his later research. Griffin considered the inhibiting assumptions made by scientists, including Cartesian views, the misunderstanding of innate behaviors, prejudice against lower animals, concern with violations of parsimony, and the assertions of the …

Arthropod Arbiters: Natural Enemy Communities Mediate The Effects Of Landscape And Local-Scale Complexity On Lygus-Induced Crop Loss In Organic Strawberries, Adrian Lu, David J. Gonthier, Amber Sciligo, Karina Garcia, Taiki Chiba, Gila Juárez, Claire Kremen
Entomology Faculty Publications
Sustainable pest management requires growers and regional land managers to consider the relationships among pest management practices, pest and natural enemy communities, crop loss, and multi-scalar habitat complexity. However, the causal links among these variables, in particular potential interactions between landscape and local-scale habitat complexity, remain underexplored. In the context of organically managed strawberry crops in California’s Central Coast, we tested the independent effects of landscape and local habitat complexity gradients on arthropod communities and crop loss using a piecewise structural equation model (PSEM). We found that landscape-scale woody habitat proportion indirectly decreased crop loss through its positive effect on …

Biosecurity factsheets
This factsheet provides information on the red fox in Western Australia (WA).
The red fox (Vulpes vulpes) is a native of the northern hemisphere where it occurs throughout most of Europe, Asia, North America, and the northern coast of Africa. The red fox was first introduced to Australia (Victoria) from Britain as early as 1845 for hunting with foxhounds. Having become successfully established in Victoria by about 1870, it colonised most of mainland Australia over the next 70 years. Foxes are not found in the most northern regions of Australia, including northwest Kimberley.
In WA, the fox is a declared …

Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano
Animal Sentience
Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …
A Dendrochronological Analysis Of Longleaf And Associated Pines From The Blackwater Ecological Preserve In Southeastern Virginia, Sarah Durham
Biological Sciences Theses & Dissertations
The field of dendrochronology utilizes annual tree ring growth data to create chronologies, which function as proxies to measure the effect of climate on radial growth. In the southeastern United States, dendrochronological studies involving the effect of climate on the growth of Pinus species exist, but significant gaps persist. For this study, I: 1) created chronologies of earlywood, latewood, and total ring-width growth for longleaf pine (Pinus palustris Mill.), loblolly pine (P. taeda L.), and pond pine (P. serotina Michx.) and 2) conducted a climate analysis on each species to determine how climatic factors affected radial …

Donkeys (Equus asinus) were first imported in substantial numbers to Australia in 1866 by Sir Thomas Elder. They were used as pack and draught animals in outlying areas of Western Australia (WA) until the 1930s. They were eventually replaced by the motor vehicle, and unwanted donkeys were released to the wild, where they became feral. The first record of feral donkeys is from the Kimberley in the early 1930s, but it is possible they became feral much earlier.
