Secondary Ecology, Tertiary World: Middle-Earth’S Ecology As Played By Aotearoa, Rory Queripel
Secondary Ecology, Tertiary World: Middle-Earth’S Ecology As Played By Aotearoa, Rory Queripel
Journal of Tolkien Research
Tolkien's self-declared love of nature (Letters: 165) is well-known and forms a thread that runs through all his work, to the point that Brian Rosebury (2003) posits that 'Middle-earth, rather than any of the characters, is the hero of The Lord of the Rings'. John Garth (2020) points out various links between the nature of The Shire and other Middle-earth locations and England, taken, as Tolkien wrote, from 'such life as I know' (Letters: 181). However, visual adaptations of Tolkien's work by Peter Jackson and Amazon have used locations in Aotearoa (New Zealand), to play the 'character' of Middle-earth on …
Unraveling Wetland Ecology: The Effect Of Abiotic Heterogeneity And Habitat Size On Wetland Plant Diversity In The Piedmont, Gregory T. Gilmore
Unraveling Wetland Ecology: The Effect Of Abiotic Heterogeneity And Habitat Size On Wetland Plant Diversity In The Piedmont, Gregory T. Gilmore
All Theses
Ecosystems around the world are seeing an unprecedented decline in biodiversity. However, to better prevent this decline we cannot only understand the drivers of biodiversity loss, but also the factors that support diversity. Traditional ecological hypotheses such as the Habitat Heterogeneity Hypothesis (HHH) and the Theory of Island Biogeography (TIB) have provided frameworks for understanding biodiversity drivers. However, recent research suggests a more nuanced relationship between heterogeneity, habitat size, and diversity than previously thought. This study looks to bridge existing research gaps by examining the ecologically and conservational important habitat of wetlands. Specifically, the study focuses on the plant diversity …

All Works
This study focused on the nematicidal potential of sea urchin-like zinc oxide nanometrics (SUZN) against the root-knot nematode Meloidogyne incognita. XRD, SEM, UV-vis spectroscopy, TEM, and EDX have been utilized to characterize the SUZN. Various SUZN concentrations (150–750 ppm) were examined for their implications for M. incognita second-stage juveniles (J2s) and egg masses, including mortality as well as hatching inhibition. The largest J2s hatching inhibition (83.07%) was seen at 750 ppm SUZN after 48 hours of incubation, whereas the lowest hatching occurred at 150 ppm when compared to the control. SUZN illustrated increased nematicidal efficiency with increasing concentration and incubation …

Effects Of Uv Filter Pollutants On The Growth Of Cucurbits And Possible Implications For Humans, Leia Staples
Effects Of Uv Filter Pollutants On The Growth Of Cucurbits And Possible Implications For Humans, Leia Staples
Undergraduate Theses
One main area of concern is the use of personal care products and pharmaceuticals in society and their long-term persistence when released into the environment (Chaturvedi et al. 2021). Cucurbits, however, are well-known for taking up pollutants (Namiki et al. 2013, Christou et al. 2019, Komives et al. 2009), so it essential to ensure that these pollutants do not negatively affect growth or productivity of plants. These plants are particularly useful in society because they have many health benefits and are consumed regularly by humans. While much research has been done on how much of the pollutant travels throughout the …

The Virginia Academy Of Science: A Scholarly Forum Over Decades For Students Of A Plant Ecologist, Stewart Ware
The Virginia Academy Of Science: A Scholarly Forum Over Decades For Students Of A Plant Ecologist, Stewart Ware
Virginia Journal of Science
As a newcomer to Virginia in 1968, I learned that annual meetings of the Virginia Academy of Science (VAS) were regarded as an excellent place for students to have their first experience giving a talk about their research to fellow scientists, and a place for faculty to get to know other Virginia scientists in their fields. Over the next four decades William and Mary students (undergraduate and graduate) and I were presenters or co-authors of 42 talks or posters at VAS annual meetings, 29 of them based on studies of plant ecology across Virginia. Two were talks by colleagues with …

Improving Riparian Restoration Planning Efforts In San Juan County Using A Site-Specific Planting Tool, Julia Jaquery
WWU Graduate School Collection
The purpose of this project was to develop a riparian planting planning tool and standard operating procedure for riparian restoration site preparation for the use of land managers working for the San Juan Islands Conservation District, to improve restoration planting establishment. The primary use of the Excel tool is to select appropriate plants for restoration sites based on the assessed soil conditions of a site. The Excel tool includes a list of riparian plant species for potential selection by land managers, with species-specific information that may inform selection. It also includes data from soil sample analysis within restoration sites, compared …
Miocene Phytolith And Diatom Dataset From 10.3myo Diatomite Formation, Fernley, Nevada, Usa, Jacopo Niccolò Cerasoni, Megan C. O'Toole, Richa Patel, Yoel E. Stuart
Miocene Phytolith And Diatom Dataset From 10.3myo Diatomite Formation, Fernley, Nevada, Usa, Jacopo Niccolò Cerasoni, Megan C. O'Toole, Richa Patel, Yoel E. Stuart
Biology: Faculty Publications and Other Works
Phytoliths are opal silica particles formed within plant tissues. Diatoms are aquatic, single-celled photosynthetic algae with silica skeletons. Phytolith and diatom morphotypes vary depending on local environmental and climatic conditions and because their silicate structures preserve well, the study of phytolith and diatom morphotypes can be used to better understand paleoclimatic and paleoenvironmental dynamics and changes. This article presents original data from an 820cm-deep stratigraphy excavated at the Hazen diatomite deposits, a high-elevation desert paleolake in the Fernley District, Northern Nevada, USA. The site has been studied for an assemblage of fossilized threespine stickleback, Gasterosteus doryssus, that reveal adaptive …
Anything But Bland: Uncovering The Hidden Diversity And Genomic Origin Of The Threatened Vanilla Spice, Paige Ellestad
Anything But Bland: Uncovering The Hidden Diversity And Genomic Origin Of The Threatened Vanilla Spice, Paige Ellestad
Boise State University Theses and Dissertations
Conserving the genetic diversity of crop species and their wild relatives has become a mounting concern as the detrimental effects of climate change, habitat destruction, and genetic erosion are being realized. In this epoch of unprecedented biodiversity loss, the genetic resources needed to improve crops may be at risk of extinction. Even one of the most iconic spices, vanilla, is threatened. Wild populations of the main vanilla producing species, Vanilla planifolia Andrews (Orchidaceae), are being rapidly extirpated due to deforestation and illegal harvesting in their native range. On top of that, clonal propagation methods within cultivated plants are hypothesized to …
Vascular Plants Of The Caribou-Targhee National Forest And Curlew National Grassland In Southeastern Idaho, Western Wyoming, And Northern Utah, Michael Daines
Vascular Plants Of The Caribou-Targhee National Forest And Curlew National Grassland In Southeastern Idaho, Western Wyoming, And Northern Utah, Michael Daines
Electronic Theses & Dissertations
Due to a historical paucity of collections from and the absence of a comprehensive floristic treatment for parts of the Caribou-Targhee National Forest and Curlew National Grassland, an updated inventory for the area was needed. I present an annotated checklist of the vascular plants documented from the Caribou-Targhee National Forest and Curlew National Grassland. A total of new 3189 voucher specimens were collected for this project in 2021 and 2022. To compile the annotated checklist, I consulted both newly collected specimens and specimen data from online botanical databases. A total of 1557 taxa (species, subspecies, varieties, and hybrids), 1423 species …
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
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 …

A Most Surprising Fern: Serendipity And Browsing In Botanical Search, Douglas Tuers
Journal of the South Carolina Academy of Science
This article is a case study of botanical field work in the eastern United States in the early twentieth century. These cases will be analyzed as instances of browsing and serendipity. Browsing and serendipity have a rich literature in information science and this article will draw on this literature in order to better understand serendipity in botany. This article will show how botanical localities support browsing and serendipity for the botanists who search them. This article will also show how botanical institutions and botanists interface with localities in order to further support browsing and serendipity. As a whole this article …

Plants And Environment: A Paleoethnobotanical Analysis Of The Vosburg Site (21fa002), Jaelyn Elizabeth Stebbins
All Graduate Theses, Dissertations, and Other Capstone Projects
Recognized archaeologically by their distinct material culture, Oneota sites exist in many ecological zones across the Upper Midwest during the late Precontact period, c. 1000-1700 CE. Consequently, the sites are hardly homogenous. Across localities, Oneota groups are recognized as food producers who grew Zea mays (maize), Cucurbita pepo (squash), and later Phaseolus vulgaris (bean). The utilization of other wild and domesticated botanical resources across localities is not as well documented.. While extensive paleoethnobotanical analyses have been completed for the late Precontact period in southeastern Minnesota (Schirmer) and southwestern Wisconsin (Arzigian), little is known about plant utilization by Oneota groups on …
Effect Of Soil Transplantation On Fungal Communities During Restoration, Thomas Luehl
Effect Of Soil Transplantation On Fungal Communities During Restoration, Thomas Luehl
All Master's Theses
Ectomycorrhizal fungi are integral parts of natural ecological systems that provide access to nutrients that would otherwise be unavailable by forming symbiotic relationships with plants. Relationships with ectomycorrhizal fungi are known to improve plant growth rate, increase plant resistance to pathogens, and improve survival. Current revegetation practices often ignore this relationship between fungi and plants. During the revegetation of the Interstate 90 Keechelus Lake wildlife overcrossing (Easton, WA), soil from forest sites adjacent to the restoration area were collected and used to inoculate a set of experimental plots to determine whether ectomycorrhizal fungi would become established in the plots and …
Investigating The Effects Of Disturbance And Competition On Establishment, Growth, And Reproduction Of The Endangered Ripariosida Hermaphrodita, Daniel Engelking
Investigating The Effects Of Disturbance And Competition On Establishment, Growth, And Reproduction Of The Endangered Ripariosida Hermaphrodita, Daniel Engelking
Theses and Dissertations (Comprehensive)
Ripariosida hermaphrodita (Virginia Mallow) is a perennial riparian plant with broad, maple-like leaves. It grows up to three meters high and is often found in large clonal patches, but sexually reproduces readily. While this plant may seem like a redoubtable competitor when growing in large colonies, it is declining across its range in North America. The only known occurrences in Canada are in southern Ontario. Prior to this study, no new populations had been recorded even though one of the known populations produces copious amounts of viable seed with potential to disperse. There are many hypotheses for its rarity, but …
Discerning Friend From Foe: Systematic Revision Of Cuscuta L. Section Indecorae Using A Combined Ecological, Morphometric, And Phylogenetic Approach., Corey Burt
Theses and Dissertations (Comprehensive)
The genus Cuscuta (Dodder; Convolvulaceae) are obligate parasitic plants. In one clade known as section Indecorae, there are species which are considered pests that pose significant threats to agricultural crop production, while other species are rare or known only from historical records. Section Indecorae contains three species: C. coryli, C. warneri, and C. indecora (the latter with three infraspecific taxa: var. indecora, var. longisepala, and var. attenuata). The systematics of section Indecorae are not currently resolved. Cuscuta indecora has a long and complicated taxonomic history with many infraspecific varieties described, and …
Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski
Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski
Theses and Dissertations (Comprehensive)
The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

Flora Of Doe Mountain Recreation Area, Johnson County, Tennessee, Benjamin Mccullough
Electronic Theses and Dissertations
A botanical inventory of Doe Mountain Recreation Area (DMRA) in northeastern Tennessee was conducted to help guide conservation-based management. A total of 484 species were found in DMRA, comprising 94 families, and 285 genera, 10 species listed in the state rare plant list, and 76 exotic species. Two species, Liatris virgata and Lycopodiella inundata, were new state records. Water in the Lycopodiella seep was an order of magnitude more acid than at other sites. An analysis of the wildland-urban interface showed that only 13% of the area was classified as uninhabited. The inventory-invasion index, introduced to quantify the relative …
Flora's Fourth Child: Race, Gender, And Botany In The British Colonial Caribbean, Brittany L. Mondragon
Flora's Fourth Child: Race, Gender, And Botany In The British Colonial Caribbean, Brittany L. Mondragon
Electronic Theses, Projects, and Dissertations
In 1824, an enslaved woman named Catalina (alias Susannah Mathison) induced an abortion by drinking an herbal mixture on the Castle Wemyss Estate in Jamaica. Consequently, the estate’s attorney denounced her as an African witchcraft practitioner. Many enslaved women faced similar convictions for their botanical knowledge as British colonists misinterpreted Obeah for witchcraft or superstition. This thesis sheds light on these women’s experiences and examines how the British Empire imposed imperial rule over enslaved women by reflecting on the intersectionality of race, gender, and botany. Focusing on the Greater Caribbean area and centering primarily around Jamaica, this research explores the …

Uses Of Native Plant Species Of A Communal Rangeland Within ‘Sierra De Huautla’ Protected Area, México, E. Cortés-Díaz, T. González-Bonilla, L. López-Aguilar, Pedro A. Martínez-Hernández, A. Hernández-Tapia
IGC Proceedings (1993-2023)
Sustainability of communal rangelands has become a major concern at national and international levels because land use conflicts and associated social conflicts allows for over-utilization of selected species making a high pressure on them and given away their places to species with no use at all becoming lands degraded and unproductive. The objective of the study was to determine floristic composition and native plant uses by local peasants. The range surface is of 4262 ha, belongs to the communal land ‘El Limon’, in Tepalcingo, Morelos, Mexico, and it is within the Natural Reserve Area “Sierra de Huautla”. Native vegetation is …

Garlic mustard is an invasive Eurasian biennial spreading in deciduous forests of North America. Garlic mustard plants in Ohio can be infected with a strain of Xanthomonas campestris, the causal agent of black rot disease in brassicas. I examined variation in susceptibility to X. campestris among garlic mustard populations, several native wild species, and agricultural crop varieties. Twenty-four garlic mustard populations were universally susceptible to X. campestris, though disease severity varied. Cardamine concatenata and Cardamine diphylla were susceptible but can phenologically escape infection in the field. Of the 14 agricultural crops tested, three cultivars (Raphanus sativus, Brassica rapa var. Rapa …
A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin Purdy
A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin Purdy
CGU Theses & Dissertations
California’s Sierra Nevada mountain range contains a disproportionate share of the state’s plant diversity and is one of the most floristically diverse regions of its size in the United States. The high Sierra Nevada, in particular, has been identified as an important center of species richness and endemism within California. Anthropogenic climate warming is expected to disproportionately affect mountain ecosystems, and models have predicted serious habitat contraction and extirpation for many alpine plant taxa. A specimen-based inventory of the vascular and non-vascular plants of Coyote Ridge and Flat was conducted to establish baseline data for one such sensitive alpine and …
The Roles Of Polyploidy, Climate, And Genetic Architecture In The Evolution Of Leaf Form In Viburnum (Adoxaceae), Morgan Kirstin Moeglein
The Roles Of Polyploidy, Climate, And Genetic Architecture In The Evolution Of Leaf Form In Viburnum (Adoxaceae), Morgan Kirstin Moeglein
Yale Graduate School of Arts and Sciences Dissertations
Plants exhibit extensive variation in leaf form, but the evolutionary drivers of this variation are not well understood. This dissertation leverages the wide diversity of leaf form and instances of leaf syndrome convergence in Viburnum to investigate trends in leaf trait evolution across the group. First, I explore how changes in chromosome number and genome size influence leaf characters of ecophysiological importance. It appears that even with extensive variation in chromosome number and genome size across Viburnum, nucleotypic changes largely do not constrain leaf traits related to ecophysiological function. I then look into a case of convergent evolution for leaf …
Short & Long-Term Restoration Dynamics Of Created Freshwater And Estuarine Wetlands, James Grant Mckown
Short & Long-Term Restoration Dynamics Of Created Freshwater And Estuarine Wetlands, James Grant Mckown
Master's Theses and Capstones
The restoration of tidal and freshwater wetlands either through compensatory mitigationor voluntary efforts have become a major strategy to conserve remaining wetland resources after historic losses and in the face of current unprecedented threats. Prior efforts of wetland restoration have often fallen short of expectations due to the reliance of a compliance success framework, which requires short monitoring timeframes, misapplies successional theories, and defines success of projects into a yes or no dichotomy. Decades of advancement in restoration ecology theory and its application to wetland ecology and botany have led to the development of a functional success framework to improve …

Compatibility Of Kura Clover And Cool Season Grass Mixtures In Michigan, P. Jeranyama, R. H. Leep, T. Dietz
IGC Proceedings (1993-2023)
Kura clover (Trifolium ambiguum Bieb.) is an alternative forage legume for rotational grazing in cool-season grass mixtures. However, compatibility with cool-season grasses is unknown. Seven cool-season perennial grasses were seeded into Kura clover in a rotational grazing experiment. The objectives of this study were to evaluate botanical composition, forage yield and quality of binary mixtures of cool-season grass with Kura clover. Field studies were conducted on a Nester (fine sandy loam) soil at Lake City Experiment Station, Lake City, MI. Botanical compositions in the first year of the study heavily favored grasses (avg. 74%) and Kura clover accounted for …
