А Review Of Heterometrus In Thailand (Scorpiones: Scorpionidae), Kazusa Kawai, Thornthan Unnahachote, Yossaphon Suttisatid, Victoria Tang

Euscorpius

Five species of the genus Heterometrus Ehrenberg, 1828 are currently confirmed from Thailand and revised, with their respective distribution range in this country updated. Heterometrus laevigatus (Thorell, 1876) is considered a nomen dubium, while its two previous junior synonyms, H. cimrmani Kovařík, 2004, stat. rev. and H. minotaurus Plíšková et al., 2016, stat. rev. are revalidated and redescribed based on the examination of topotypes. Females of H. minotaurus Plíšková et. al., 2016, stat. rev. were also collected and examined, and their characters are herein described with a special attention to sexual dimorphism. Furthermore, some populations previously regarded as H. …

Euscorpius

A new example of scorpion leg regeneration is reported in an adult male Mesobuthus mesopotamicus (Penther, 1912). A claw (pretarsus) was observed to regenerate at the distal end of the tibia of the left leg II. The regeneration case is described and illustrated.

The Miacomet Movement, Charles Duce

Masters Theses

Nantucket MA, is an island that has failed to refine and regulate the unreasonable uses of freshwater supply, and re-establish the purification processes involved with filtering our wastewater. The validity in claiming re-evaluation for Nantucket’s immoderacies in freshwater consumption and implausibility's in existing wastewater treatments, is seemingly irrefutable. Along with these detriments, Nantucket experiences harsh coastal erosion conditions that are rapidly altering beach profiles and diminishing irreplaceable habitats. Similarly, coastal flooding is causing ecological displacement and in some instances ecological degradation.

The relentlessness and fleetingness sparked by Nantucket’s climatic realities require willing and able action to mitigate impacts; but our …

On The Edge Of The "Er-Ocean" State, Mariesa Travers

Masters Theses

This thesis will explore how hard coastal infrastructure methods can be redesigned by softening the coastal edge to support the ecosystem and enhance public access to the beach. By referencing and arguing against techniques used by the U.S. Army Corps of Engineers (USACE) as a solution to deal with coastal erosion, this process will propose a regenerated design system. Through a series of material experiments, this research works with natural processes and flows, to create transitory systems that erode and ebb with the coast.

Reintroducing Hemp (Rongony) In The Material Palette Of Madagascar: A Study On The Potential Of Hemp Clay Components And Its Impact On Social And Ecological Communities., Henintsoa Thierry Andrianambinina

Masters Theses

When mentioning the word hemp, especially in the local language of Madagascar, the literal translation does not set it apart from marijuana, as they are both called “rongony” - creating the stigma around hemp as the negative stereotype of marijuana. However, the material has been used by the ancestors of Madagascar, as well as across cultures, in its fibrous form to produce fabrication like textile goods and packaging. During colonization, the prohibition of hemp intensified, and since then, any activity related to either of these plants is prohibited and will end in severe punitive measures. This thesis explores the strengths …

Reproduction, Early Development, And Larval Rearing Of The Climbing Perch Anabas Testudineus (Teleostei: Anabantidae) In Captivity, Frolan A. Aya, Reylan C. Gutierrez, Luis Maria B. Garcia

The Philippine Agricultural Scientist

Induced spawning, early development, and larval rearing of the climbing perch Anabas testudineus were examined under captive conditions. Five female climbing perch [125.33 ± 3.27 mm SL; 70.67 ± 5.59 g BW] were paired with apparently mature males (108.50 ± 3.97 mm SL; 39.27 ± 4.70 g BW) and induced to spawn with 5,000 IU human chorionic gonadotropin (hCG) + 0.5 mL Ovaprim kg BW^-1. All hCG + Ovaprim-injected fish spawned 9 – 11 h after hormone administration but saline-injected fish (control group) failed to spawn. Mean egg production per female, fertilization and hatching rates, and larval production …

The Influence Of Microorganisms On Human Health, Tiffany Bui

University Honors Theses

The purpose of this thesis is to explore the interplay between the environment, lifestyle, and composition of human microbiomes across different communities, with a specific focus on immune and digestive health. This literature review investigates three distinct types of communities: isolated/traditional, transitional, and urban/industrialized communities, each characterized by unique environments, societal structures, and interactions. These factors contribute to the distinct microbial populations and compositions within each community. It is impossible to avoid contact with microorganisms as they are present in every aspect of our lives, from the air we breathe, the water we drink, the soil we walk on, the …

Illuminating The Drivers Of Genomic Diversification In Lamprologine Cichlids Of The Lower Congo River, Naoko P. Kurata

Dissertations, Theses, and Capstone Projects

Freshwater fishes are extraordinarily diverse, considering their available habitats represent a tiny proportion of the earth’s surface. Rivers connect heterogeneous habitats in a linear form and provide excellent simplified models to understand how aquatic biodiversity evolves. In particular, the lower Congo River (LCR) in west Central Africa consists of a dynamic hydroscape exhibiting extraordinary aquatic biodiversity, endemicity, and morphological and ecological specialization. This system is thus an excellent natural laboratory for understanding complex speciation and population diversification processes. In my research, I explore various drivers of diversification, and adaptive evolution in rheophilic lamprologine cichlids endemic to the LCR, including Lamprologus …

A Foundational Population Genetics Investigation Of The Sexual Systems Of Solanum (Solanaceae) In The Australian Monsoon Tropics Suggests Dioecious Taxa May Benefit From Increased Genetic Admixture Via Obligate Outcrossing, Jason T. Cantley, Ingrid E. Jordon-Thaden, Morgan Roche, Daniel S. Hayes, Stephamie Kate, Christopher T. Martine

Faculty Journal Articles

Solanum section Leptostemonum is an ideal lineage to test the theoretical framework regarding proposed evolutionary benefits of outcrossing sexual systems in comparison to cosexuality. Theoretically, non-cosexual taxa should support more genetic diversity within populations, experience less inbreeding, and have less genetic structure due to a restricted ability to self-fertilize. However, many confounding factors present challenges for a confident inference that inherent differences in sexual systems influence observed genetic patterns among populations. This study provides a foundational baseline of the population genetics of several species of different sexual systems with the aim of generating hypotheses of any factor—including sexual system—that influences …

Towards Urban Biodiversity: Simulating Design Parameters For Wildlife-Inclusive Green Infrastrcuture, Alisa Abdulghany, Baher Farahat

BAU Journal - Creative Sustainable Development

As of 2021, more than half of the global population resides in urban areas. This resulted in an overwhelming footprint affecting species habitat areas leading to biodiversity loss. By definition, urban biodiversity is the diversity of living things within the urban realm. By providing chances for habitat as part of new developments, preserving on-site habitats, and attempting to connect with the local ecosystems, we can help promote biodiversity. Green infrastructure (GI), which includes all semi-natural areas in the urban context, can serve as a vessel for biodiversity. Therefore, the problem can be defined by the urban footprint that expands on …

A Baseline Assessment Of Migratory And Resident Bird Use Of A Prairie Restoration Site In Eastern Washington, Madilyn J. Odiorne, Brynn A. Richey, Ruby L. Hammond

2023 Symposium

Prairies, and other types of grassland ecosystems, have suffered some of the most profound losses worldwide, due to anthropogenic factors such as fossil fuel extraction, agriculture, and climate change. Likewise, organisms inhabiting grassland ecosystems have become extirpated across much of their historical range, not the least of which has been a 50% decline in grassland birds since the 1960s. In response to losses of intact prairie in eastern Washington, a 120-ac site has been established on the EWU campus to regenerate native prairie and monitor changes in the ecosystem as native plants recolonize and replace non-natives. Because birds are an …

Euscorpius

A new species Androctonus kunti sp. n. is described and illustrated from Iğdır Province of Turkey. This population was first recorded by Birula (1896) as A. crassicauda (Olivier, 1807). A. kunti sp. n. is compared with A. crassicauda as well as A. turkiyensis Yağmur, 2021, which was recently described from Turkey

Practical Solutions To The Invasion Of Lionfish In Utila, Honduras: Science, Education, Food, And Jewelry, Carolyn Corley

Undergraduate Honors Theses

Lionfish (Pterois sp.) are invasive species capable of devastating coral reef ecosystems due to their lack of predators, large appetites, generalist diet, high fecundity, and rapid spawning rates. As lionfish have expanded their distribution across the Caribbean, many conservation groups have taken it upon themselves to systematically remove these predators from environments where they are threatening native species. However, few have involved the community the way I observed while interning with the Whale Shark and Oceanic Research Center in Utila, Honduras. Protecting coral reefs is extremely important, especially in small communities like Utila, where the majority of people’s …

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

The Response Of An Avian Community To Intercropping And Forest Management Practices In A Private Working Pine Forest, Rebecca Doyne Bracken

Theses and Dissertations

Within managed pine forest systems, a plethora of bird species exist throughout the lifecycle of a stand akin to what may be experienced through post-disturbance regeneration in a natural forest system. I sought to address how breeding avian communities shift across time in response to stand aging and forest management, evaluate species-specific responses to stand conditions, investigate the responses of at-risk avian species to forest management, and determine avian non-breeding, over-wintering presence in a managed loblolly pine (Pinus taeda) forest. I conducted breeding bird point count and vegetation surveys within five stands of privately owned and managed pine forest in …

Pasturelands As Natural Climate Solutions: A Socioecological Study Of Tree Carbon And Beef Production Trade-Offs, Bela Starinchak

Masters Theses, 2020-current

Forest restoration is the most effective natural climate solution, with the potential to sequester 37% of the carbon dioxide (CO₂) needed to reach the Paris climate mitigation goal. Cattle pastures offer an underutilized opportunity to increase global forest restoration efforts, improve biodiversity, and maximize carbon storage through the adoption of management strategies that prioritize the incorporation of trees into pasturelands. However, remote estimations of tree carbon storage in pastoral systems have never been field-verified and their accuracy is unclear. Furthermore, the effect of increased trees on cattle production is understudied across biomes. Lastly, the restoration potential of these …

Mechanistic Examination Of Protist-Mediated Plant Growth Through The Comparative Development Of Medicago Truncatula, Shane Connolly

University Scholar Projects

Protists are known to increase plant growth through two main mechanisms: the microbial loop and the alteration of the root microbiome. The microbial loop is a nutrient recycling method in which protists provide inorganic nitrogen ions to the plant. Alteration of root microbiome leads to the removal of plant pathogens and shifting communities towards plant growth-promoting bacteria (PGPB). This study aimed to elicit which mechanism could produce the largest boost in shoot weight for Medicago truncatula. A series of microcosm experiments were explored in which M. truncatula was grown with variable microbiome structures to allow for mechanism differentiation. The …

Aspects Of Distribution, Abundance, Habitat, And Life History Of The Caddo Madtom (Noturus Taylori), A Narrow Endemic Of The Ouachita Highlands, Brittany L. Mccall, Brook L. Fluker

Southeastern Fishes Council Proceedings

The Caddo Madtom, Noturus taylori, is a small catfish endemic to the Ouachita Mountain ecoregion in Arkansas, with habitat altered by land use practices and reservoir dams. We examined aspects of distribution, abundance, habitat, and life history of N. taylori during seasonal sampling from winter 2016 through fall 2017. Our sampling data were concordant with previous studies that suggested N. taylori is more widespread and has higher catch per unit effort in the Caddo River drainage when compared to the upper Ouachita River drainage. We did not detect N. taylori in the Little Missouri River drainage, where it is …
