Taxonomy and Relationships Within Polemonium foliosissimum (Polemoniaceae): Untangling a Clade of Colorful and Gynodioecious Herbs

Abstract— New molecular and ecological data have necessitated taxonomic revisions of several species complexes within Polemonium (Polemoniaceae), including P. foliosissimum, an herbaceous perennial widespread in the Intermountain West of the United States. As currently circumscribed, P. foliosissimum is a highly polymorphic species of four taxonomic varieties. One of the most striking morphological traits of the species is its diversity in flower color, which is unusual for the genus. Several species have been proposed based on this variation in flower color. However, these names have been treated as infraspecific taxa because previous authors have concluded that the presence of micropollen grains throughout the geographic range of the species complex indicated partial hybrid sterility and therefore incomplete barriers to gene flow. However, recent evidence suggests that micropollen is instead due to a gynodioecious breeding system. Using 128 nuclear loci and eight quantitative morphological traits, I clarify relationships and taxonomy within the species complex. I show that what is currently circumscribed as four varieties of P. foliosissimum represent five species that, in addition to differing in corolla color, differ in leaflet number, corolla size, and vegetative and floral pubescence. I propose a new species endemic to the White Mountains of southeastern Arizona, Polemonium apachianum. This study provides a new phylogenetic context and taxonomic circumscription to serve as a framework for future research on the evolution of floral color and sexual systems in a previously misunderstood but evolutionarily exciting system.

Apprentice in Law and Journalism

The death of Kyriakos left Venizelos head of the family. The granting by the Ottomans of the Halepa pact and the development of civil society created conditions in which, with help from Mitsotakis, he could exploit openings in the law and journalism, and eventually politics. With young friends he took over Mitsotakis's journal White Mountains (lefka ori), in which he commented on political issues concerning Crete, Greece, Turkey and the Balkans. In parallel he developed his legal practice, representing clients from all confessions. He stood for restraint in the pursuit of union with Greece, recognizing the need for Crete to move in step with Greece. He argued in his journalism for responsibility in public life, meaning an end to rousfeti (corruption) and the abuse of the freedoms introduced by the Halepa pact. He developed early a political philosophy based on the general interest.

Foliar Endophytic Fungi from the Endangered Eastern Mountain Avens (Geum peckii, Rosaceae) in Canada

Eastern Mountain Avens (Geum peckii Pursh, Rosaceae) is a globally rare and endangered perennial plant found only at two coastal bogs within Digby County (Nova Scotia, Canada) and at several alpine sites in the White Mountains of New Hampshire (USA). In Canada, the G. peckii population has declined over the past forty years due in part to habitat degradation. We investigated the culturable foliar fungi present in G. peckii leaves at five locations with varying degrees of human impact within this plant species’ Canadian range. Fungal identifications were made using ITS rDNA barcoding of axenic fungal cultures isolated from leaf tissue. Differences in foliar fungal communities among sites were documented, with a predominance of Gnomoniaceae (Class: Sordariomycetes, Phylum: Ascomycota). Habitats with more human impact showed lower endophytic diversities (10–16 species) compared to the pristine habitat (27 species). Intriguingly, several fungi may represent previously unknown taxa. Our work represents a significant step towards understanding G. peckii’s mycobiome and provides relevant data to inform conservation of this rare and endangered plant.

Cultural Inheritance and Innovation—Taking the Heilongjiang Garden Design of the Garden Expo as an Example

With the rapid development of social science and technology civilization, and the acceleration of urbanization, the requirements of urban landscape planning and design are also paying more and more attention to the design concept of “adopting measures to local conditions and putting people first”. Therefore, the inheritance and innovation of urban landscape planning and design based on the culture that can represent local characteristics is a respect for and inheritance of traditional regional culture, the integration of traditional culture and the culture of the new era, and the inevitable trend of modern landscape planning and development. This essay uses the Heilongjiang Garden Engineering Design Project of the Garden Expo as a case to carry out the regional landscape planning and design, inheriting the regional characteristics, and proposing the design concept of “nature and culture growing on black soil”, integrating the characteristics of white mountains and black water into the garden, and seeing the big from the small Interpret the characteristic landscape impression of Heilongjiang and provide a reference for the design of the exhibition garden project in the future.

Alfonsas Aldonis: Writing a Soviet Poem

The article studies the genesis of poems by one of the most famous Lithuanian poets of the Soviet era Alfonsas Maldonis (1929–2007). It follows the methodology of genetic criticism and compares versions of manuscripts and texts of poems that have already been published. The main attention is given to poems “Awakening from Sleep”, “White Mountains”, “Morning Wind”. The poet’s first manuscripts are usually more ordinary, containing everyday realities and even open critique of Soviet life. While editing the manuscripts, the author sometimes only deletes or replaces some words with neutral ones (names of religious holidays, realities reminiscent of Soviet repression), but more often, the image is fundamentally redesigned, the particulars are replaced with abstract images, creating a multifaceted reading. The original ideas do not disappear but seem to be taken into the poem’s underground layer. The manuscripts’ analysis reveals how Maldonis created his distinctive poem and how an internal censor is involved in the process, suggesting which words would never be printed in a book published by an official publisher. Rarely, but there are also opposite cases where Soviet symbols are inserted into an ideologically neutral text. Maldonis’s poetry, however, contains signs similar to what Czesław Miłosz called the “captive mind”. It is difficult to say whether those few sovietisms stem from internal conviction or external ideological pressure to write bright, optimistic texts.

Direct Inversion Method of Fault Slip Analysis to Determine the Orientation of Principal Stresses and Relative Chronology for Tectonic Events in Southwestern White Mountain Region of New Hampshire, USA

The orientation and relative magnitudes of paleo tectonic stresses in the western central region of the White Mountains of New Hampshire is reconstructed using the direct inversion method of fault slip analysis on 1–10-m long fractures exposed on a series of road cuts along Interstate 93, just east of the Hubbard Brook Experimental Forest in North Woodstock, NH, USA. The inversion yields nine stress regimes which identify five tectonic events that impacted the White Mountain region over the last 410 Ma. The inversion method has potential application in basin analysis.

438. Characteristics and Epidemiology of a Native American Community with a High Prevalence of COVID-19

Background COVID research and reporting has focused on large urban populations. However, limited data suggests that rural Native American (NA) populations are disparately impacted. We serve a well-defined NA population of ≈18,000 that is relatively geographically isolated in the White Mountains of eastern Arizona. Our first case SARS-CoV-2 was confirmed April 1st. We have since confirmed an attack rate significantly higher than most of the United States. We provide testing and case trends in addition to characteristics of the first 800 cases. Methods We sequentially reviewed the charts of all laboratory-confirmed COVID-19 patients from April 1 to June 3, 2020. In addition to calculating prevalence and rates, we provided summary statistics that were used to describe testing breakdown, demographics, symptoms, and co-morbidities. Results From April 1 to June 3, we tested 2,662 persons, of which 884 (33.2%) were positive. The estimated prevalence of the time of writing is 4.9% and the rate of 4,911 per 100,000 persons. Data compiled from the first 800 laboratory-confirmed patients is summarized in table 1. Median age for confirmed cases was 40.6 (IQR 28–54). 555 cases (72.1%) were symptomatic. The most common symptoms were cough (67.7%), subjective fever (39.5%), and muscle aches (36.8%). 30.6% of confirmed cases were asymptomatic at the time of testing. The majority of cases were among persons aged 30–39 years (22.9%). Some of the most common comorbidities in confirmed cases included cardiovascular disease (30.4%), substance abuse (30.1%), and diabetes (25.0%). There were 18 (2.04%) deaths. Clinical findings among symptomatic patients Conclusion We observed a significantly higher prevalence (10-times) and attack rate of (17-times) COVID-19 in a well-defined NA population, when compared to the general Arizona population. We provide characteristics of these cases and report that nearly a third were asymptomatic at the time of testing. More research is needed to understand the rapid spread of COVID-19 in vulnerable rural communities. Disclosures All Authors: No reported disclosures

Quaternary slip rates on the White Mountains fault zone, eastern California: Implications for comparing geologic to geodetic slip rates across the Walker Lane

The White Mountains fault zone in eastern California is a major fault system that accommodates right-lateral shear across the southern Walker Lane. We combined field geomorphic mapping and interpretation of high-resolution airborne light detection and ranging (LiDAR) digital elevation models with 10Be cosmogenic nuclide exposure ages to calculate new late Pleistocene and Holocene right-lateral slip rates on the White Mountains fault zone. Alluvial fans were found to have ages of 46.6 + 11.0/–10.0 ka and 7.3 + 4.2/–4.5 ka, with right-lateral displacements of 65 ± 13 m and 14 ± 5 m, respectively, yielding a minimum average slip rate of 1.4 ± 0.3 mm/yr. These new slip rates help to resolve the kinematics of fault slip across this part of the complex Pacific–North American plate boundary. Our results suggest that late Pleistocene slip rates on the White Mountains fault zone were significantly faster than previously reported. These results also help to reconcile a portion of the observed discrepancy between modern geodetic strain rates and known late Pleistocene slip rates in the southern Walker Lane. The total middle to late Pleistocene slip rate from the southern Walker Lane near 37.5°N was 7.9 + 1.3/–0.6 mm/yr, ∼75% of the observed modern geodetic rate.
