Glenn Robert Webb (1918–1999) was a prolific author on the reproductive biology of the terrestrial pulmonates (Mollusca) of the United States. Webb published almost 110 papers, notes and abstracts, many containing detailed descriptions of the functional morphology and reproduction of these gastropods, which remain of value in resolving their phylogeny. Webb described two family-level names (both still considered valid), ten genus-level names (at least seven remain valid), and ten species-level names, all for terrestrial pulmonates. Webb also edited and published the journal Gastropodia, which appeared in thirteen issues, from 1952–1994, and contained extensive original research on the terrestrial pulmonates. Several other malacologists, notably Leslie Hubricht, also published articles and described new species in Gastropodia. This paper provides a biography of Webb, a complete bibliography of his publications, and a list of his taxa, along with a list of other authors’ publications and new taxa in Gastropodia. Webb’s research collection, including some type specimens, and his notebooks, are now housed in the Field Museum of Natural History, Chicago.

Тhe agromyzid (Diptera: Schizophora: Agromyzidae) fauna of America north of Mexico is described in the first part of this publication, including a genus key and discussions on morphology, life history and classification. The second part is a species-level revision of the family in the “Delmarva” states of the United States of America, that is, of the District of Columbia and the surrounding states of Delaware, Maryland, Virginia and West Virginia. The fauna of this region includes 156 species. This study presents 346 new state and provincial records and 23 new country records, two of which are new continental records (Agromyza abiens Zetterstedt and A. apfelbecki Strobl). Liriomyza endiviae Hering is no longer considered to occur in North America. Fifteen species are newly described: Agromyza echinalissp. nov., Melanagromyza brunkeisp. nov., M. eoflacensissp. nov., M. glyptossp. nov., M. rutellasp. nov., Ophiomyia capitoliasp. nov., O. cupreasp. nov., O. galiodessp. nov., O. heleiossp. nov., O. kaliasp. nov., O. laticolissp. nov., Cerodontha (Poemyza) ungulasp. nov., Phytomyza avicursasp. nov., P. catenulasp. nov., and P. winklerisp. nov. Four new species-level synonyms and one genus-level synonym are provided: Agromyza marmorensis Spencer syn. nov. is included as a synonym of A. aristata Malloch; Melanagromyza fastosa Spencer, syn. nov. is included as a junior synonym of Ophiomyia tiliae (Couden); Melanagromyza verbesinae Spencer is considered a synonym of M. vernoniana Steyskal; Phytomyza ranunculoides Spencer, syn. nov. is included as a junior synonym of Phytomyza loewii Hendel; the genus Liomycina Enderlein, syn. nov. is included as a junior synonym of Phytobia Lioy. Ophiomyia ultima (Spencer), comb. nov. is recombined from Melanagromyza. Euhexomyza albicula Spencer, stat. reinst., comb. nov. is resurrected from synonymy with E. winnemanae (Malloch). New host records are given.

In 1928, a collection of marine fish trematodes was made at the United States Bureau of Fisheries Station at Beaufort, North Carolina; thirty-six of fifty-one species of fishes examined contained trematodes; only one or two specimens of some species were examined. Only Monogenea were collected from Elasmo branchs. The following report includes the digenetic forms identified. Type specimens of all new species are deposited in the United States National Museum.

This study shows the results of a rotifer faunistic survey in thalassic waters from 26 sites located in northeastern U.S. states and one in California. A total of 44 taxa belonging to 21 genera and 14 families were identified, in addition to a group of unidentifiable bdelloids. Of the fully identified species, 17 are the first thalassic records for the U.S., including Encentrum melonei sp. nov. and Synchaeta grossa sp. nov., which are new to science, and Colurella unicauda Eriksen, 1968, which is new to the Nearctic region. Moreover, a refined description of Encentrum rousseleti (Lie-Pettersen, 1905) is presented. During the survey, we characterized samples by different salinity values and ecosystems and compared species composition across communities to test for possible ecological correlations. Results indicate that both salinities and ecosystems are a significant predictor of rotifer diversity, supporting that biodiversity estimates of small species provide fundamental information for biomonitoring. Finally, we provide a comprehensive review of the diversity and distribution of thalassic rotifers in the United States. The results of the present study increase the thalassic rotifer record for the U.S. from about 105 (87 at species level) to 124 (106 at species level) taxa.

This book is a new account of utopian writing. It examines how eight writers—Henry David Thoreau, W. E. B. Du Bois, Osip and Nadezhda Mandel'shtam, Anna Akhmatova, Wallace Stevens, Ezra Pound, and J. H. Prynne—construct utopias of one within and against modernity's two large-scale attempts to harmonize individual and collective interests: liberalism and communism. The book begins in the United States between the buildup to the Civil War and the end of Jim Crow; continues in the Soviet Union between Stalinism and the late Soviet period; and concludes in England and the United States between World War I and the end of the Cold War. In this way it captures how writers from disparate geopolitical contexts resist state and normative power to construct perfect worlds—for themselves alone. The book contributes to debates about literature and politics, presenting innovative arguments about aesthetic difficulty, personal autonomy, and complicity and dissent. It models a new approach to transnational and comparative scholarship, combining original research in English and Russian to illuminate more than a century and a half of literary and political history.

Abstract Objective: The citation history of a published article reflects its impact on the literature over time. We conducted a comprehensive bibliometric analysis to identify the most cited papers on CHD in children. Methods: One-hundred and ninety journals listed in Journal Citation Reports were accessed via Web of Science. Publications with 250 or more citations were identified from Science Citation Index Expanded (1900–2020), and those relating to structural CHD in children were reviewed. Articles were ranked by citation count and the 100 most cited were analysed. Results: The number of citations ranged from 2522 to 309 (median 431, IQR 356–518), with 35 published since 2000. All were written in English, most originated from the United States (74%), and were published in cardiovascular journals, with Circulation (28%) the most frequent. There were 86 original research articles, including 50 case series, 14 cohort studies, and 10 clinical trials. The most cited paper was by Hoffman JI and Kaplan S on the incidence of CHD. Thirteen authors had 4 or more publications in the top 100, all of whom had worked in Boston, Philadelphia, San Francisco, or Dallas, and the most prolific author was Newburger JW (9 articles). Conclusions: Citation analysis provides a historical perspective on scientific progress by assessing the impact of individual articles. Our study highlights the dominant position of US-based researchers and journals in this field. Most of the highly cited articles remain case series, with few randomised controlled trials in CHD appearing in recent years.

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791
