Hot Is Rich—An Enormous Diversity Of Simple Trichal Cyanobacteria From Yellowstone Hot Springs, Jan Kaštovský, Jeffrey R. Johansen, Radka Hauerová, Mildred Akagha

2023 Faculty Bibliography

In 2019, cyanobacterial samples were collected from thermal sites in Yellowstone National

Park. In this paper, we discuss the considerable richness of representatives of simple filamen- tous cyanobacteria. Using a polyphasic approach, one new genus, Copelandiella, with two species

(C. yellowstonensis and C. thermalis) and eight additional new species Albertania prattii, K. anagnostidisii, Kovacikia brockii, Leptolyngbya tildenae, L. vaporiphila, Nodosilinea calida, N. igneolacustris, and Oculatella castenholzii were described. At the same time, by analyzing our new molecular data, we concluded that other genera of trichal cyanobacteria can be merged with existing genera: species within the genus Plectolyngbya are herein transferred …

A New Species Of Arrhenia (Agaricales, Hygrophoraceae) From Guizhou Province, China, Jing Wang, Huan Gao, Dong Mei Liu, Chun Ying Deng, Shao Qi Zhou

Turkish Journal of Botany

Arrhenia nivea is a new bryophilous species of Arrhenia from a valley in southwestern China'a subtropical monsoon humid climate zone.The species is characterized by pure white basidiomata with an irregularly discoid to cupulate 1.5-4.5 mm diameter pileus, reduced hymenium, nonamyloid basidiospores, lack of cystidia, the presence of clamps, and no incrusted pigment of the pileipellic hyphae. Phylogenetic analysis using ITS sequence data confirmed that it arised from a pathway separate from other species of Arrhenia.

Seed Morphology Of Some Plantago (Plantaginaceae) Species In Iran And Its Systematic And Phylogenetic Implications, Saeed Mohsenzadeh, Masoud Sheidai, Fahimeh Koohdar

Turkish Journal of Botany

Plantago is a cosmopolitan genus with approximately 200 species and various infrageneric classifications have been reported. In this study, the seed morphologies of 19 species of Plantago from Iran were studied and documented in detail using scanning electron microscopy and light microscopy. The studied species were grouped by using statistical analyses such as a minimum spherical cluster method based on Euclidean distance, principal coordinate analysis, and multidimentional scaling. We have described four types based on the seed shape and states of the inner side of the studied seeds: convex- angular type, convex-elliptic type, flat-elliptic type, and concave-elliptic type.

A Biodiversity Survey Of The Soil Crusts Of The Geographically Isolated San Nicholas Island, California, Usa And Description Of Species In Three Genera (Atlanticothix, Pycnacronema, Konicacronema) Previously Restricted To Brazil Using A Polyphasic Approach To Cyanobacterial Taxonomy, Brian Jusko

Masters Theses

San Nicholas Island, California, USA is a geographically-isolated island that experiences a semiarid climate and exhibits significant topographic and geologic diversity. Access to the island is restricted to the public and, as a result, only one previous study has been done on the algal biodiversity of its biological soil crusts. The previous study used morphology as the sole basis of species identification, and it was the aim of this study to corroborate and expand upon the results by including molecular data. Using 16S rRNA and 16S–23S ITS sequences and phylogenetic analyses, a diverse set of taxa were identified and are …

Diversity And Distribution Of Bryozoans Of The Northern To Central Rocky Outer Coast Of California, Ismael Chowdhury

Cal Poly Humboldt theses and projects

The phylum Bryozoa is one of the most diverse groups of marine invertebrates, with a global distribution that spans marine and fresh waters. This study analyzes the Bryozoa in infralittoral communities on rocky surfaces from northern California (Point Saint George) to central California (Estero Bay), spanning 940 kilometers and encompassing 12 rocky intertidal sites. Although recent studies on bryozoan taxonomy and phylogeny have increased due to scanning electron microscopy (SEM) and high throughput sequencing, there is still a lack of studies on species found in shallow waters at intertidal depths, particularly in the northeastern Pacific.

Could There Be A Relationship Between Feeding Characteristics And The Shape Of Condylus Occipitalis And Foramen Magnum In Mammals?, Yasi̇n Demi̇raslan, İsmai̇l Demi̇rci̇oğlu, İftar Gürbüz, Funda Aksünger Karaavci, Abdullah Ortadeveci, Özcan Özgel

Turkish Journal of Veterinary & Animal Sciences

The aim of the study was to investigate the shape of the foramen magnum and condylus occipitalis of mammalian species belonging to different feeding groups. For this, two-dimensional geometric morphometric method analyses were applied. The data from the skulls of the 12 species were used. In principal component analysis, the first three principal components accounted for 70.353%of the total shape variation. According to the first principal component, the dorsal edge of the condylus occipitalis and foramen magnum contributed the most to shape variation. Most of the individuals were correctly separated according to the feeding groups. The most accurate grouping features …

Brunner, G. Eyal, F. L. González-Zapata, S. E. Kahng, K. R. W. Latijnhouwers, P. Muir, V. Z. Radice, J. A. Sánchez, M. J. A. Vermeij, O. Hoegh-Guldberg, S. J. Jacobs, P. Bongaerts

Biological Sciences Faculty Publications

Background: Mesophotic coral communities are increasingly gaining attention for the unique biological diversity they host, exemplified by the numerous mesophotic fish species that continue to be discovered. In contrast, many of the photosynthetic scleractinian corals observed at mesophotic depths are assumed to be depth-generalists, with very few species characterised as mesophotic-specialists. This presumed lack of a specialised community remains largely untested, as phylogenetic studies on corals have rarely included mesophotic samples and have long suffered from resolution issues associated with traditional sequence markers.

Results: Here, we used reduced-representation genome sequencing to conduct a phylogenomic assessment of the two dominant mesophotic …

Revisiting The Type Species Of The Genus Homidia (Collembola, Entomobryidae), Guo-Qiang Zhang, Yu-Xin Zhao, Feng Zhang

Faculty, Staff and Student Publications

Homidiacingula Börner, 1906, the type species of the genus Homidia Börner, 1906, is widespread from India to Southeast Asia, but its detailed morphological characteristics have not yet been described. We examined the morphology of specimens of H.cingula from Indonesia and southwestern China and confirmed their conspecific status by comparing their DNA barcoding sequences. We also compared the morphology of H.cingula with other two closely related species, confirming the valid species status of H.subcingula Denis, 1948. Our study provides new taxonomic and molecular data for the genus Homidia.

Taxonomic Revision And Morphometric Analysis Of Selected Anthurium (Araceae) Species From Bolivia And Peru, Daniel M. Tarazona Ocana

Theses

The genus Anthurium (Araceae) consists of around 1,200 species distributed in the Neotropics, particularly in Central and South America. The montane forests in the eastern flank of the Andes, ranging from northern Ecuador to central Bolivia; hereafter, the East Andes Gradient region, are particularly rich in terms of species diversity, and include an understudied group of Anthurium species endemic to the region. Within this group of species, some taxa are difficult to distinguish from each other mainly due to the lack of identification keys, incomplete species descriptions and unknown synonyms. In this study, a combination of traditional taxonomic techniques and …

Neotype Designation For Papilio Fulgerator Walch, 1775 (Hesperiidae: Eudaminae), Jing Zhang, Qian Cong, Gerardo Lamas, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

The discovery that a skipper butterfly Telegonus fulgerator (Walch, 1775), previously placed in the genus Astraptes Hübner, [1819], is a complex of many similar-looking species-level taxa with different COI barcodes, caterpillar foodplants, and body patterns, and subtle differences in adult phenotypes raised a question about which species is the original T. fulgerator. To answer this question, being unable to locate its holotype, we designate the neotype of Papilio fulgerator Walch, 1775, a female specimen from Suriname in the Zoological State Collection, Munich, Germany. This neotype will form the foundation for a comprehensive revision of the T. fulgerator complex based …

The Ecology And Evolution Of Species Rarity In Oaks (Quercus Spp.), Yingtong Wu

Dissertations

Rare species are susceptible to extinction due to ecological and genetic factors. Understanding the distribution, ecology, and evolution of rare species can provide useful information for effective conservation. To investigate species rarity, this dissertation focuses on a species-rich and ecologically diverse genus, Quercus (oaks). In Chapter 1, I aimed to understand how interactions between hosts and soil microbes contribute to habitat restriction in oak species. I performed a soil inoculum experiment on two pairs of sister oak species that show habitat divergence. I found that host-specific soil microbes contribute to habitat divergence and exclusion among sister species of oaks, but …

A Comprehensive Phylogeny Of Stick And Leaf Insects (Insecta: Phasmatodea) Reveals Widespread Taxonomic Incongruence, Jackson B. Linde

Theses and Dissertations

Stick and leaf insects (Insecta: Phasmatodea) are a mesodiverse order of insects distributed across the world. These masters of masquerade crypsis are riddled with analogous morphological characters and lack a robust taxonomic framework. It seems that convergent evolution and the re-evolution of complex traits like wings and ocelli is perhaps the rule rather than the exception in stick insects. To investigate the re-acquisition of traits in this unique study system, a robust phylogenetic framework is essential. Our analyses combine traditional Sanger data with a transcriptomic backbone to provide the most corroborated phylogenetic analyses to date. To accomplish this, we employ …

Its Rdna Barcodes Clarify Molecular Diversity Of Aquatic Hyphomycetes, Ricardo Franco-Duarte, Isabel Fernandes, Vladislav Gulis, Fernanda Cássio, Cláudia Pascoal

A New Phyllophaga (Listrochelus) Timida Group Species From Baja California Sur (Coleoptera: Scarabaeidae: Melolonthinae), William B. Warner

Insecta Mundi

Phyllophaga (Listrochelus) baja, new species (Coleoptera: Scarabaeidae: Melolonthinae), is de­scribed and illustrated. Its relationship to other species in the “timida group” is discussed.

Morón (2002) reviewed the Phyllophaga Harris (Listrochelus Blanchard) species near P. timida (Horn) and included a key to the eight known species of the “timida group.” Many species in this group are difficult to dis­tinguish from one another via external characters; however, the male genital shape is diagnostic for each. Here I describe a new species from Baja California Sur, Mexico, that falls within that group.

Invasion Of Two Labidesthes Species Through The Tennessee-Tombigbee Waterway In Mississippi, Benjamin H. Chaffins, Calvin R. Rezac, Robert J. Ellwanger

Southeastern Fishes Council Proceedings

We re-identified the collections of Labidesthes sicculus at Mississippi Museum of Natural Science after a 2015 publication by Werneke and Armbruster elevated Labidesthes vanhyningi to the full species level. Following re-examination of specimens, 64% were identified as L. vanhyningi and 36% were identified as L. sicculus. During our study, a chronological review of the distribution of both species suggested bi-directional invasion through the Tennessee-Tombigbee Waterway. Prior to the connection of the two drainages, the only Labidesthes located in the Tennessee drainage was L. sicculus, where as L. vanhyningi was allopatric within the Tombigbee drainage. However, following canal construction, we …

A Morphological And Molecular Study Of Phallus Multicolor In Indonesia, Rudy Hermawan, Ivan Permana Putra, Mega Putri Amelya, Mochammad Rizky Wangsadireja Gunawan

Makara Journal of Science

Phallus is known as stinkhorn mushroom. Previous reports have shown that this genus is recognized by the size and color of the basidioma, which is a highly plastic morphological character that can potentially lead to misidentification. In Indonesia, no study has combined morphological and molecular analyses to identify Phallus. This study aimed to determine the identity of Phallus that has the orange color of an indusium found in Bekasi, West Java, Indonesia. The morphological characteristics were described by observing the macroscopic and microscopic features of fresh specimens. Molecular analyses were performed based on the internal transcribed spacer 4/5 region …
