Turkish Journal of Botany

Oxytropis is a taxonomically challenging genus within the tribe Galegeae of the family Fabaceae. Despite its systematic importance, the seed morphology of Oxytropis has been poorly investigated. In the present study, we examined the seed morphology of 18 Oxytropis species representing 10 sections from the Pakistan, with the aim of evaluating the diagnostic value of seed traits using both light and scanning electron microscopy. The current investigation revealed two distinct seed shapes, namely cordiform and prolonged reniform, across the studied taxa. Seed length ranged from 1.75 mm in O. crassiuscula to 2.3 mm in O. duthieana, while seed width varied …

Unveiling The Diversity Within Salvia Caespitosa Sensu Lato (Lamiaceae): Three New “Hidden” Endemic Species From Türkiye​, Ferhat Celep, Musa Doğan, Gali̇p Akaydin, Ahmet Kahraman, Ersi̇n Karabacak, Ömer Çeçen, Meti̇n Armağan, Chun-Lei Xiang, Bryan T. Drew

Turkish Journal of Botany

Documenting species, particularly those that are threatened or endangered, is fundamental to biodiversity conservation. However, many taxa remain scientifically unrecognized, being either undiscovered or unpublished. While some plants can be easily recognized as new species, other identifications are obscured by morphological, taxonomic, and nomenclatural complexity. Detecting cryptic or “hidden” species is therefore essential to understanding biodiversity and plant evolution. Our revisionary studies on Salvia demonstrate that the morphologically complex Salvia caespitosa is not a single species but instead comprises at least four distinct species, three with narrow distributions. This conclusion is supported by integrative evidence from extensive field studies, herbarium …

Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber

Master's Theses

Landscape stewardship is an integral role for land managers that becomes more important when rare or endangered species occur within managed areas. Conservation across the landscape is a primary concern for land managers, but resources allocated for conservation can be limited due to many competing goals. Taxonomic uncertainty surrounding rare and endangered taxa, particularly plant taxa, that have historically been classified solely using morphological features further complicates conservation planning. One such taxon is Potentilla rupincola, a rare plant endemic to the eastern Rocky Mountains in Colorado. For over a century, botanists have debated whether P. rupincola is a distinct species …

Leveraging Historic Collections: Investigating Morphometric Differentiation In Members Of The Arisaema Triphyllum (L.) Schott (Araceae) Species Complex, Morgan Bradley Russell

Graduate Theses and Dissertations

The Jack-in-the-pulpit (Arisaema triphyllum (L.) Schott) is an herbaceous perennial herb of North America, and its taxonomic history is full of confusion and rank shifts. Now split into six species, the A. triphyllum species complex consists of morphologically similar taxa that have differing ploidy levels. In Chapter I, I compiled a detailed introduction and history for these taxa, focusing on their taxonomic complexity and morphological ambiguity in herbarium specimens and immature plants. I also presented their ploidy distinctions and how the implications of polyploidy may hold answers to parsing them apart, especially in dried herbarium specimens where defining characteristics are …

Effects Of Plant Growth-Promoting Microorganisms On Microbial Community Dynamics And Plant Growth Responses Of Aeroponically Cultivated Spinach, Veronica Snow

All NMU Master's Theses

Regional food insecurity caused by the inability to use conventional farming techniques year-round in cold climates increases the need for access to quality, locally sourced, and affordable foods year-round. Shifting from a soil-based system to aeroponics can increase yields, as aeroponic systems are not weather-reliant and can operate year-round. Aeroponics, a subgroup of hydroponics, induces growth by misting nutrient-rich solutions onto the plant roots. These systems use space and water more efficiently and rely less on fertilizers and pesticides but are vulnerable to errors in nutrient application, power loss, and rapid pathogen spread. Adding Vermicompost (VCT) and plant growth-promoting microorganisms …

Phylogenomics And Biogeography Of Zinniinae (Asteraceae: Heliantheae) Using Plastome And Nuclear Datasets, Samuel Victor Skibicki

Graduate Theses, Dissertations, and Problem Reports (ETD)

Zinniinae is a subtribe of plants in the daisy family (Asteraceae) and the sunflower tribe (Heliantheae). Traditionally, seven genera were included in the subtribe: Echinacea, Heliopsis, Philactis, Sanvitalia, Tehuana, Trichocoryne, and Zinnia. The subtribe is poorly understood from a phylogenetic and taxonomic standpoint, and I undertook a phylogenetic investigation of Zinniinae, using both the plastid genome (plastomes) and the nuclear genome, to learn more about the evolutionary history of this clade. Plastomes were assembled to build a phylogenetic tree, targeted sequence capture was used to compile the nuclear datasets, and a chronogram was created to estimate date ranges for …

Phylogenomics Of The Tribe Leonureae Reveals A New Genus: Paraleonurus (Lamiaceae, Lamioideae), Mei-Lin Qian, Ya-Ping Chen, Tuncay Di̇rmenci̇, Yue Zhao, Guo-Xiong Hu, Fei Zhao, Ferhat Celep, Bo Li, Chunlei Xiang

Turkish Journal of Botany

With approximately 80 species across six genera (Leonurus, Lagopsis, Panzerina, Lagochilus, Chaiturus, and Loxocalyx), the tribe Leonureae represents one of the most morphologically diverse tribes within the subfamily Lamioideae of Lamiaceae. Previous studies indicated that Leonurus and Lagopsis are not monophyletic, and relationships among and within these genera remain unclear due to limited sampling and DNA markers. In this study, we present the most comprehensive phylogenomic analyses of Leonureae based on complete plastome sequences and 127 nuclear loci retrieved from next-generation sequencing data. Our results provide strong evidence for the monophyly of Leonureae, which can be further divided into six …

Novelties In Funalia And The Status Of Fomitella (Polyporaceae, Basidiomycota), Virton Rodrigo Targino De Oliveira, Paulo Roberto De Assis Alves, Nelson Correia De Lima-Júnior, Carla Santos, Nelson Lima, Leif Ryvarden, Josef Vlasák, Tatiana Baptista Gibertoni

Turkish Journal of Botany

During studies on the taxonomical delimitation of some species of Funalia, some inconsistencies were observed in the genus. Based on morphological and phylogenetic analyses, Fomitella supina was positioned within the Funalia clade, thus the synonymization of the genus and the new combination of F. supina are proposed. Funalia glabrorigens is also combinated in the genus, while Coriolopsis hainanensis is suggested as a synonym of F. floccosa and F. rigida is assumed as a distinct species from F. floccosa. A table with morphological comparison of the 10 Funalia species confirmed by molecular analyses is also presented.

Using Leaf Spectra To Elucidate The Taxonomy And Ecology Of Living And Dried Plants, Natalia L. Quinteros Casaverde

Dissertations, Theses, and Capstone Projects

Identifying plants and understanding of changes in plant communities are crucial to the conservation and management of nature. The shortwave spectral reflectance of leaves is a promising tool for rapidly identifying species at different taxonomic ranks and predicting important plant functional traits. However, the spectral reflectance of leaves changes in response to biotic and abiotic conditions.

The aim of this dissertation is to investigate the potential of shortwave spectral reflectance to investigate (Chapter 1) how its variation affects the accuracy of methods used to predict plant taxonomies and what environmental factors most influence biophysically predicted traits, (Chapter 2) what are …

Characterizing New Plant Fossils With Woody Growth From The Battery Point Formation Of Quebec (Canada), Emma T. Casselman

Cal Poly Humboldt theses and projects

The oldest woody growth has been recognized in several Early Devonian (ca. 410-395 Ma) euphyllophytes. Their taxonomic diversity is difficult to evaluate due to a lack of quantitative methods for comparing plants based on secondary xylem anatomy. In turn, this hinders understanding of their implications for the evolution of plant development. To develop metrics that quantify secondary xylem anatomy and allow for conclusive comparisons, I investigated extant taxa and Early Devonian fossil woody taxa. I developed multiple metrics for quantifying tracheid size as a function of position in the secondary xylem and tested them on a dataset of extant gymnosperms. …
