Patterns And Sources Of Variation In Heterospecific Pollen Deposition In Flowers Of The Native Blue Cardinal Flower (Lobelia Siphilitica), Allie Drinnon 2023 East Tennessee State University

Patterns And Sources Of Variation In Heterospecific Pollen Deposition In Flowers Of The Native Blue Cardinal Flower (Lobelia Siphilitica), Allie Drinnon

Undergraduate Honors Theses

Plants species interactions via pollinators are a model system to understand the mechanisms that generate plant diversity in nature. However, most studies have focused on plant-plant interactions via pollinator attraction while ignoring the role of plant-plant interactions via pollen transfer. Heterospecific pollen transfer (henceforth HP) can be common and have negative fitness effects. Negative HP fitness effects may prompt the evolution of adaptive strategies to minimize them. However, the extent of spatial variation in HP load size within and among populations, a tenet for natural selection, remains unexplored. Such knowledge would hence constitute a first step in advancing our understanding ...


A New Scorpion Genus And Species From China, Qianxie Solegladi Gen. Et Sp.N. (Scorpiones: Pseudochactidae), Victoria Tang 2022 Marshall University

A New Scorpion Genus And Species From China, Qianxie Solegladi Gen. Et Sp.N. (Scorpiones: Pseudochactidae), Victoria Tang

Euscorpius

A new monotypic genus belonging to the basal scorpion family Pseudochactidae Gromov, 1998, Qianxie solegladi gen et. sp. n., is described from Yunnan Province of China. The family is recorded from China for the first time, vastly extending its known geographic range. The new genus shares morphological characters with both Pseudochactas Gromov, 1998 and Troglokhammouanus Lourenço, 2007. It differs from Pseudochactas and is similar to Troglokhammouanus in the shapes of anterior and posterolateral carapace margins, form of the circumocular sutures, distance between median ocelli, development of dorsoventral projection of patella, length of tarsal spinules, recurvature of the lateral margins and ...


A Standardized List Of Scorpion Names In Chinese, With An Etymological Approach, Victoria Tang 2022 Marshall University

A Standardized List Of Scorpion Names In Chinese, With An Etymological Approach, Victoria Tang

Euscorpius

The scientific (Latin) names of scorpion species are widely used across the world by both experts and amateurs. However, in China, there is a great need for designating standardized Chinese names for various scorpions since it is difficult for those not familiar with Latin alphabet to memorize the scientific names. Currently used Chinese names often cause confusion and misunderstanding due to a lack of standardized, unified naming. The present work critically revises the existing formal Chinese scorpion names, vernacular names (used by local population and amateurs), and the names used in Chinese scientific publications, along with the confusion they have ...


Review Of Orthochiroides Kovařík, 1998 With Description Of A New Species (Scorpiones: Buthidae), František Kovařík, Graeme Lowe 2022 Marshall University

Review Of Orthochiroides Kovařík, 1998 With Description Of A New Species (Scorpiones: Buthidae), František Kovařík, Graeme Lowe

Euscorpius

The genus Orthochiroides Kovařík, 1998 is reanalyzed. Revised diagnoses and new illustrations for the genus and all four of its species are presented. A new species, O. somalilandus sp. n. from Somaliland is described and illustrated. Phylogenetic relationships of the genus with several other similar genera of small buthids are inferred from a parsimony analysis of 43 discrete morphological characters. The recent synonymy of Orthochiroides with Orthochirus is refuted and the genus is revalidated.


Diversity-Productivity Relationships In Forests Of The Southeastern United States: Leveraging National Inventory Data And Tree Functional Traits, Elizabeth Baach 2022 Mississippi State University

Diversity-Productivity Relationships In Forests Of The Southeastern United States: Leveraging National Inventory Data And Tree Functional Traits, Elizabeth Baach

Theses and Dissertations

Numerous studies have evaluated the relationship between biodiversity and productivity, with general trends suggesting a positive relationship. While most studies only use species richness, this study also analyzed how productivity changes with functional diversity and Shannon’s diversity index. Functional diversity gives important context to the examination of biodiversity-productivity relationships due to the direct link between organisms’ functional traits and their role in a given ecosystem. This study used data from the USDA Forest Service Forest Inventory and Analysis (FIA) database collected in Alabama, Louisiana, and Mississippi to estimate plot-level productivity and diversity. Structural equation modeling was used to determine ...


Trophish: Building A Global Database Of Freshwater Trophic Interactions, Jacob M. Ridgway 2022 University of South Dakota

Trophish: Building A Global Database Of Freshwater Trophic Interactions, Jacob M. Ridgway

Honors Thesis

Freshwater management and research frequently use the trophic data of freshwater fishes. Despite this fact, it is difficult to perform a simple search of dietary information for any one fish species. FishBase represents, to our knowledge, the largest compilation of freshwater dietary information to date. However, it excludes a large portion of the ecological literature due to its development taking place prior to the creation of most modern scientific search engines. Our project (TroPhish) is building upon FishBase by digitizing approximately 130 years of data from the fish predation literature. Data from the primary and grey (e.g. theses, dissertations ...


Using Color To Identify Neotropical Parrots In Early Modern European Art: Recognizing Limitations And Avoiding Pitfalls Through Integration Of Scientific And Artistic Knowledge, Deniz Martinez 2022 Lindenwood University

Using Color To Identify Neotropical Parrots In Early Modern European Art: Recognizing Limitations And Avoiding Pitfalls Through Integration Of Scientific And Artistic Knowledge, Deniz Martinez

The Confluence

Colorful Neotropical parrots were amongst the first and most frequent exotic animals to be imported by Europeans from the “New World” of the Americas, becoming key figures in what would become known as the Columbian exchange. There has been an ongoing effort to locate and identify images of Neotropical parrots in the visual record of early modern Europe, with the classification of many remaining unsettled in the scholarship. Proper identification of these images can be valuable data for reconstructing historical biogeography and transatlantic trade; especially compelling is the potential of certain “mystery parrots” in the visual record to support the ...


Life After Death – Does Carcass Biodiversity Scale With Carcass Body Size?, Troy Warfield 2022 University of Arkansas, Fayetteville

Life After Death – Does Carcass Biodiversity Scale With Carcass Body Size?, Troy Warfield

Biological Sciences Undergraduate Honors Theses

Mammals play a large role in the ecosystems where some, especially large-bodied mammals, act as ecosystem engineers. Mammal carcasses, particularly those of large body mass act as a temporary island of dense nutrients that support other organisms, including other mammal species, for an extended period. Research in this field currently focuses on the link between mammal carcass size and nutrient availably or on non-mammalian size and biodiversity, but little is available on the correlation between mammal carcass size and its influence on ecosystem biodiversity. Here we ask, does the available biomass (i.e., body size) of the carcass affect its ...


Operatic Mysticisms: Mountains, Deserts, Waterscapes, Andrew Demczuk 2022 East Tennessee State University

Operatic Mysticisms: Mountains, Deserts, Waterscapes, Andrew Demczuk

Electronic Theses and Dissertations

Operatic Mysticisms: Mountains, Deserts, Waterscapes examines the ways we encounter environments as readers/viewers of operas, literature, film, and sound recordings, and how each medium requires different detail-gathering techniques. Respective to the previously mentioned mediums, Sun & Sea (2017), Mount Analogue (1952), El Mar La Mar (2017), and Energy Field (2010) are analyzed by engaging with environmental media studies and invention. Reflecting the nature of each landscape—summits of mountains, aporias of deserts, and mysteries of waterscapes—an elemental approach is taken in investigating how these spaces may be noticed, internalized, recorded, and traversed by both the artist and viewer. With ...


Describing The Effect Of Thin Layer Sediment Placement On Coastal Microbial Communities Using Foraminifera Diversity, Elizabeth B. Billings 2022 University of Rhode Island

Describing The Effect Of Thin Layer Sediment Placement On Coastal Microbial Communities Using Foraminifera Diversity, Elizabeth B. Billings

Senior Honors Projects

Salt marshes are rich ecosystems that play an important role in aquatic food systems and prevent erosion while also providing essential habitats for wildlife. Climate change has resulted in rising sea levels and erosion of these coastal wetlands. Thin Layer Sediment Placement (TLP) is a restoration effort being implemented to mitigate the effects of climate change on coastal ecosystems. The TLP process raises elevation of the marsh and provides substrates for vegetative growth by spraying dredged sediment over existing marsh. The impacts of TLP on microbial populations is not widely understood, therefore metrics are required to study the effects of ...

Providing undergraduate students effective, learning experiences to develop technical and cultural competency prepares them to address this challenge and become global leaders in their disciplines. A three-year experiential research and extension project brought together 14 students and 10 faculty mentors to investigate smallholder farmers practicing conservation-compatible adjacent to the Vaca Forest Reserve in Belize. We used an agroecological approach to foster systems-level thinking and develop transdisciplinary skills of undergraduate students. Students completed applied individual research projects that explored ...


Diversity Of Bacteriophage In Burkholderia Species, Abigail Price 2022 Bowling Green State University

Diversity Of Bacteriophage In Burkholderia Species, Abigail Price

Honors Projects

Bacteriophages are viruses that infect and replicate within bacteria and offer the potential of a therapeutic alternative to chronic infections that do not respond to antibiotic-based therapies. B. vietnamiensis is one of a number of Burkholderia species involved with chronic drug resistant infections in the lungs of individuals with compromised respiratory systems, as found in those with chronic obstructive pulmonary disease and, most especially, are of particular significance in patients with cystic fibrosis. The diversity of the Burkholderia species is explored by using online databases and looking at bacteriophage or phage-encoding viruses found in B. vietnamiensis. The open reading frames ...


Using Conservation Genetics To Inform Reintroduction Of The Endangered Mottled Duskywing (Erynnis Martialis), Shayla Kroeze 2022 The University of Western Ontario

Using Conservation Genetics To Inform Reintroduction Of The Endangered Mottled Duskywing (Erynnis Martialis), Shayla Kroeze

Electronic Thesis and Dissertation Repository

Habitat loss and climate change have caused declines in species diversity and abundance globally, including in butterflies which are important components of many ecosystems. Reintroductions are increasingly used to reverse diversity loss but are most effective when informed using genetics. I developed 24 microsatellites and characterized genetic structure and diversity of the endangered Mottled Duskywing (Erynnis martialis) in Ontario and neighbouring provinces and states. These were used to inform a planned reintroduction in Ontario. Populations had moderate levels of genetic diversity, however all but the largest populations may be subject to appreciable levels of genetic drift. Populations more than 8 ...

Genetic Variation In The Ohio Population Of Tonguetied Minnow (Exoglossum Laurae), Emmily Moses, Sarah Armstrong, Madeline Williams

ONU Student Research Colloquium

A singular population of tonguetied minnow (Exoglossum laurae) inhabits a ~50-km segment of the Mad River of western Ohio. Tonguetied minnow is Endangered in Ohio as a consequence of its small geographic range and low abundance. For this study, the polymerase chain reaction (PCR) was used amplify five genetic loci from 35 tonguetied minnow captured from the Mad River. Loci included two mitochondrial genes, the NADH-dehydrogenase 2 (ND2) and the control region (D-loop). From the nuclear genome, myosin heavy chain 6 (myh6) and β-actin (β-act) introns were amplified, as well as a portion of the major histocompatibility (Mhc-IIB) locus. PCR ...


Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood 2022 Bowling Green State University

Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood

Honors Projects

Global lakes are experiencing an increase in toxic algal blooms that can be damaging to the environment. These blooms are caused by cyanobacteria, specifically a species called Planktothrix. Skinn Lake, in Ohio, is a location of a cyanobacterial bloom that is mainly populated by Planktothrix rubescens. This lake was further examined to identify the major toxin-producing bacteria and identify environmental microbes surrounding the bloom. When the data was examined it was found that the microbiomes of the lake greatly differed between the winter (bloom) months and the summer (non-bloom) months. This difference can be viewed within the nutrient analysis from ...


Microbial Diversity And Community Structure In Sediments Associated With The Seagrass (Thallassia Testudinum) In Apalachicola Bay, Florida, Rahma Ahmed, Thomas McElroy, Troy Mutchler 2022 Kennesaw State University

Microbial Diversity And Community Structure In Sediments Associated With The Seagrass (Thallassia Testudinum) In Apalachicola Bay, Florida, Rahma Ahmed, Thomas Mcelroy, Troy Mutchler

Symposium of Student Scholars

Seagrass is an angiosperm which provides many ecosystem services in coastal areas, such as providing food, shelter and nurseries for many species, and decreasing the impact of waves on shorelines. A global assessment reported that 29% of known seagrass meadows are in a state of decline due to the effects of human activity. Seagrass is commonly found in shallow marine waters where they form meadows containing a microbiome that plays an important role in providing nutrients for seagrass growth, though little is known about the microorganisms within the seagrass meadow sediments. Our project collected sediments from seagrass meadows and adjacent ...

From Individuals To Communities: The Effect Of Climate Change On Ectothermic Predators, Matthew Lawrence Meehan 2022 The University of Western Ontario

From Individuals To Communities: The Effect Of Climate Change On Ectothermic Predators, Matthew Lawrence Meehan

Electronic Thesis and Dissertation Repository

The living components of ecological systems exist within a nested hierarchy, consisting of individuals, populations, and communities. Because of this nestedness, climate change can greatly impact ecological systems, as whole-organism metabolic and physiological demands change for ectotherms under warming, the effects of which may compound with every succeeding level. Therefore, a multi-level approach can better isolate how climate change will reshape ecological systems. In my doctoral research, I used feeding and mesocosm experiments to examine how climate change affects ectothermic predators at the individual-, population-, and community-level, using mesostigmatic mites (Arachnida: Parasitiformes) as my model predator. My research objectives were ...


Historical And Future Role Of Wilmar Palm Oil In Deforestation Of Indonesian Borneo, Sam Coroniti III 2022 University of South Carolina - Columbia

Historical And Future Role Of Wilmar Palm Oil In Deforestation Of Indonesian Borneo, Sam Coroniti Iii

Senior Theses

Borneo is one of the most biologically diverse locations on Earth, with thousands of endemic and rare species forming unique and intricate relationships throughout the ecosystems. Orangutans, elephants, leopards, tigers, rhinos, and many more species call this island their home, although population levels for all of the mentioned species have been in seriously decline over recent decades. The loss of primary rainforest that provides the most critical habitat for these species has occurred at the highest rate that has ever been seen on Earth, leading to extreme land conversion and greenhouse gas producing operations. The primary driver of these actions ...
