Eimeria longirostris (Apicomplexa: Eimeriidae) from Vagrant Shrew, Sorex vagrans (Mammalia: Eulipotyphla: Soricidae), from Montana, USA
Acta Parasitologica, 2021Co-Authors: Chris T. Mcallister, John A. Hnida, John M. KinsellaAbstract:Purpose Nothing is known about the coccidian parasites of Vagrant shrews, Sorex vagrans Baird, 1868. Here we report, for the first time, the occurrence of Eimeria longirostris Hertel and Duszynski, 1987 from faecal contents of S. vagrans from Montana, USA. Methods Faecal samples, collected in July and August 2020 from six pitfall-trapped Vagrant shrews as well as faeces from two masked shrews , Sorex cinereus Kerr, 1792, and one American pygmy shrew, Sorex hoyi Baird, 1857 from Missoula County, Montana, USA, were examined for coccidian parasites. Samples were placed in individual vials containing aqueous potassium dichromate. They were examined for coccidia after flotation in Sheather’s sugar solution, measured, and photographed. Results Three (50%) S. vagrans and one (50%) S. cinereus were found to be passing oocysts of Eimeria longirostris Hertel and Duszynski, 1987; the single S. hoyi was negative. Oocysts from S. vagrans were subspheroidal and measured (average L × W) 16.1 × 14.4 µm with an L/W ratio of 1.1. One (typically) to two polar granules was present but a micropyle and oocyst residuum were absent. Sporocysts were ovoidal and measured 9.6 × 6.2 µm with an L/W ratio of 1.6. A Stieda body was present but subStieda and paraStieda bodies were absent. The sporocyst residuum was composed of various sized granules typically scattered between and across the sporozoites but sometimes formed a loose aggregate or compact mass. Conclusion We document a new host and new geographic record for E. longirostris from S. vagrans and report the coccidian from S. cinereus for the third time but the first report from specimens from Montana. This coccidian has now been reported from at least 12 species of shrews within the genus Sorex in 14 US states and two provinces in Canada.

morphological and molecular differentiation of staphylocystis clydesengeri n sp cestoda hymenolepididae from the Vagrant shrew sorex vagrans soricomorpha soricidae in north america
Zootaxa, 2013Co-Authors: Vasyl V Tkach, Arseny A Makarikov, John M. KinsellaAbstract:Staphylocystis clydesengeri n. sp. is described from shrews Sorex vagrans in Montana and Washington, United States. It differs from the only previously known North American representative of the genus, S. schilleri, in having more numerous (37-42 vs. 22-30) and larger (39-44 microm vs. 27-30 microm) rostellar hooks. The two species also differ in several other important characters such as relative length of the cirrus pouch, position of gonads and shape of mature proglottides. Morphological differentiation of the new species from all previously known Palearctic species of Staphylocystis from Sorex is also provided. Differentiation from Staphylocystis parasitic in crocidurine shrews is not provided due to the high level of specificity among shrew hymenolepidids to the host genera and much greater levels of sequence divergence between Staphylocystis from the two groups of shrews. Molecular differentiation based on 2,800 base pair long sequences of nuclear ribosomal RNA (complete ITS region and partial 28S region), 663 base pair long sequences of mitochondrial nad1 gene and 542 base pair long sequences of mitochondrial ribosomal 16S gene strongly support the status of Staphylocystis clydesengeri n. sp. Relative utility of the DNA fragments used in this study for reliable differentiation among closely related species of mammalian hymenolepidids is discussed. Nuclear ribosomal RNA region appears to be too conserved for this purpose. Use of at least one mitochondrial gene in addition to nuclear ribosomal RNA or without it, is recommended. Vampirolepis novosibirskiensis Sawada & Kobayashi, 1994 is transferred to Staphylocystis as a junior synonym of S. furcara (Stieda, 1862). Rodentolepis gnoskei Greiman & Tkach, 2012 is transferred to Pararodentolepis Makarikov and Gulyaev, 2009 as a new combination Pararodentolepis gnoskei (Greiman & Tkach, 2012) n. comb.

molecular identification of an avian dicrocoeliid brachylecithum mosquensis from a Vagrant shrew sorex vagrans in montana u s a
Comparative Parasitology, 2009Co-Authors: John M. Kinsella, Vasyl V TkachAbstract:Gravid dicrocoeliid flukes recovered from the liver of a Vagrant shrew, Sorex vagrans, in Montana, U.S.A., were identified as Brachylecithum mosquensis by comparing their morphology and DNA sequences to specimens from 2 American robins, Turdus migratorius, from North Dakota, U.S.A. This is the first record in the world, to our knowledge, of a bird dicrocoeliid from a shrew and also the first record in North America of a dicrocoeliid parasitic in the genus Sorex.

helminths of the Vagrant shrew sorex vagrans from western montana usa
Acta Parasitologica, 2007Co-Authors: John M. KinsellaAbstract:A total of 19 helminth species (1 trematode, 11 cestodes, 7 nematodes) were collected from 45 Vagrant shrews, Sorex vagrans (Mammalia, Soricidae), in western Montana, USA. One trematode (Brachylaima sp.), 2 cestodes (Paruterina candelabraria, Staphylocystoides longi), and 6 nematodes (Baruscapillaria rauschi, Eucoleus oesophagicola, Longistriata meylani, Paracrenosoma sp., Parastrongyloides winchesi, Pseudophysaloptera formosana) are reported for the first time from this host. Baruscapillaria rauschi n. comb. is proposed for Capillaria rauschi Read, 1949. This is the first record of merocercoids of P. candelabraria from a shrew, and the first report of the genus Paracrenosoma in North America.

Factors affecting the distribution and abundance of autumn Vagrant New World warblers in northwestern California and southern Oregon.
PeerJ, 2018Co-Authors: C. John Ralph, Jared D. WolfeAbstract:Birds found outside their typical range, or Vagrants, have fascinated naturalists for decades. Despite broad interest in vagrancy, few attempts have been made to statistically examine the explanatory variables potentially responsible for the phenomenon. In this study, we used multiple linear regression to model the occurrence of 28 rare warbler species (family Parulidae) in autumn in northern California and southern Oregon as a function of migration distance, continental population size, distance, and bearing to both closest breeding population and breeding population center. In addition to our predictive model, we used capture data from the California coast to 300 km inland to examine relationships between the presence of Vagrant warblers, regional warbler species richness and age class distribution. Our study yielded three important results: (1) vagrancy is strongly correlated with larger North American population size; (2) Vagrants are more common at some coastal sites; and (3) where young birds are over-represented, Vagrants tend to occur-such as on the coast and at far inland sites. Of the many explanations of rare and Vagrant individuals, we feel that the most likely is that these birds represent the ends of the distributions of a normal curve of migration direction, bringing some few migrants to locations out of their normal migratory range as Vagrants. We also examine the underrepresented species that, according to our model, are overdue for being recorded in our study area.

Constitutionalization as Statecraft: Vagrant Nation and the Modern American State
Law & Social Inquiry, 2018Co-Authors: Karen M. TaniAbstract:This essay showcases the contribution of Risa Goluboff's Vagrant Nation (2016) to one field of scholarship that the book scarcely mentions: the historical literature on the American state. In Goluboff's account of the fall of the “vagrancy law regime” in the “long 1960s” I see vital questions about the nature of the modern American state and the endurance of older, seemingly antithetical modes of governance. Given the trends that state-focused scholars have illuminated—for example, toward centralization of power and the protection of individual rights—what allowed for vague, locally enforced vagrancy laws to survive so late into the twentieth century? What ultimately triggered their demise? In mining Vagrant Nation for answers, this essay also urges scholars to contemplate “constitutionalization” as a form of statecraft. In giving a constitutional law framing to the grievances of “Vagrants,” federal courts reinforced key tenets of the modern American state, including the supremacy of national law over competing legal orders and the desirability of being a rights-bearing member of the nation-state. Simultaneously, these court decisions left open other, more “modern” possibilities for regulating the kinds of people (poor, nonwhite, unpopular) whom vagrancy laws once ensnared.
