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 …

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 …

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

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 …

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 …

The Collaboration Between Art And Botany, Hee So, Sierra Beecher

Undergraduate Research Posters

Using past research from my work study with Dr. Beecher where a team of students focused on quantitative and diagnostic anatomies of salt marsh and beach grasses on the Atlantic coasts, I used the research collected and created vector-based diagrams that were easily readable for Biology students at VCU. These illustrations were used in a manuscript we have been preparing, which has been accepted by the “Castanea” scientific journal. During the research fellowship, I was able to design a poster that portrayed the benefits of collaboration between art and botany, and Dr. Beecher presented the poster at the ASPB conference …

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

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

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 (1997-2023)

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 …

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 …

Exploring The Host Range, Impacts, And Distribution Of Black Rot Disease On Alliaria Petiolata, Gabriela Ivette Harney-Davila

Browse all Theses and Dissertations

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 …

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

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 (1997-2023)

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 …

Epiphyte-Host Dynamics Between Pyropia And Nereocystis In Central California, Daniel Joseph Gossard

Master's Theses

Macroalgal epiphytism is widespread, but many unique epiphyte-host interactions remain poorly understood. Pyropia nereocystis is an annual northeastern Pacific species that has evolved to primarily epiphytize the annual kelp Nereocystis luetkeana. I examined three aspects of Pyropia-Nereocystis epiphyte-host dynamics in the southern extent of the host’s range: (1) temporal variation in epiphtyte presence; (2) growth of gametophyte and sporophyte (conchocelis) stages using transplantation experiments; and (3) effects of epiphyte depth and host characteristics on the recruitment and biomass of the epiphyte. Pyropia exhibited a shift in presence on Nereocystis that differed interannually as a function of Nereocystis density and Nereocystis …

Conservation Genetics Of Nabalus Serpentarius And Its Common Congener, Nabalus Trifoliolatus (Asteraceae) With Implications On Conservation, Steven Michael Ballou Jr

Electronic Theses and Dissertations

Nabalus serpentarius (Pursh) Hooker is a species of concern to conservation management on the island of Nantucket, MA where four populations have been recently observed. A comparative population genetic study was carried out on N. serpentarius and a common congener, N. trifoliolatus using genetic markers developed from Taraxacum kok-saghyz and Nabalus serpentarius. Evaluations of genetic diversity and population structure of both Nabalus species on Nantucket were conducted. Nabalus serpentarius showed no reduction in population genetic variation as compared to the common congener, and the two species demonstrated similar and very low levels of population genetic structure. These data indicate that …

Lepidopteran Granivory Reduces Seed Counts In A Rare Species Of Riparian Scour Prairies, Cheyenne Moore, Angela J. Mcdonnell, Scott Schuette, Christopher T. Martine

Faculty Journal Articles

In Pennsylvania Baptisia australis var. australis is found along only four waterways: the Allegheny River, Youghiogheny River, Clarion River, and Red Bank Creek. Because of its limited distribution and small number of extant populations, the species is considered state-threatened in Pennsylvania. In addition, the riparian prairie habitat that Pennsylvania Baptisia australis var. australis is restricted to is also in decline and considered vulnerable. Because of these conservation concerns, insights into the natural history of the taxon in the state is valuable and will inform conservation efforts. Field surveys and fruit collections along the Allegheny River and herbarium collections were used …

Patterns Of Genetic Divergence Across Geographically Variable Populations Of Xanthisma Gracile (Asteraceae), Lavanya Challagundla, Lisa E. Wallace

Biological Sciences Faculty Publications

Premise of research. Numerous biotic and abiotic factors can contribute to local selection and lead to geographic structure and genetic divergence between populations. The southwestern United States contains many distinctive plant communities, ranging from woodlands to desert scrub, that are shaped by species adapting to local variation in elevation, precipitation, seasonality, and soils. Given this variation, species occurring across diverse habitats are expected to harbor high genetic diversity and exhibit significant genetic differences associated with environmental variation.

Methodology. Here, we studied the genetic divergence of populations of Xanthisma gracile (Asteraceae) across Arizona using amplified fragment length polymorphisms and evaluated associations …

Investigation Into The Genetic Provenance Of Three Rare Plants With East-West Disjunction Patterns In Pennsylvania., Scott Schuette, Christopher T. Martine

Other Faculty Research and Publications

Rare plant conservation relies on an understanding of the natural history, biology and ecology, and real and potential threats to their populations to inform state regulations that serve to protect the species from extirpation. This work often involves extensive field surveys over several years to determine population sizes and whether those populations are seeing reductions in number of individuals necessary to maintain the genetic diversity within and between those populations. Species and populations with high genetic diversity are better equipped to withstand sudden changes to their habitats that derive from land use changes and changing climate. There are a variety …

Exploring Zosterophyll Relationships Within A More Broadly Sampled Character Space: A Focus On Anatomy, Megan Nibbelink

Cal Poly Humboldt theses and projects

Important constituents of Siluro-Devonian floras, zosterophylls gave rise to the lycophytes. I explore the relationships of 18 zosterophyll species from 16 genera, maximizing sampling of anatomy. Using phylogenetic and phenetic methods, I (1) assess the influence of tree rooting, taxon sampling, and morphological vs anatomical characters on the stability of relationships; and (2) compare phylogenetic and phenetic methods in terms of relationships recovered. Phenetic analyses show sensitivity to taxon sampling and support placement of Renalia among zosterophylls, but do not provide results that are strongly congruent with those of phylogenetic analyses. Phylogenetic analyses demonstrate that taxon and character sampling significantly …

Analysis Of The Variables Affecting Plant Species Richness In Deserts, Eli R. Kallison, Ellen Thompson, Maddison Keen, Rusty Newman

IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt

There are many hypotheses that attempt to explain patterns of species diversity in different environments. Deserts are a great place to study changes in species richness because they are relatively nutrient bare and exhibit low precipitation. This barebones environment means that slight shifts in climate and geography may lead to clear changes in species richness. We investigate how temperature, precipitation, water and light availability, latitude, elevation and other variables affect plant species richness in 20 deserts.
