Pterourus Appalachiensis (Papilionidae: Papilioninae), A New Swallowtail Butterfly From The Appalachian Region Of The United States, Harry Pavulaan, David M. Wright Jun 2002

Pterourus Appalachiensis (Papilionidae: Papilioninae), A New Swallowtail Butterfly From The Appalachian Region Of The United States, Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

A new univoltine species of Tiger Swallowtail, Pterourus appalachiensis, is described from the southern Appalachian Mountain region of the eastern United States. This distinct swallowtail has remained unrecognized by lepidopterists since the description of its sympatric congener Pterourus glaucus (Linnaeus) in 1758. Historical accounts of Tiger Swallowtails from this region pertain specifically to glaucus and cannot be attributed to this new species. Morphology, voltinism, phenology, distribution, and behavioral traits indicate species level status of appalachiensis. Although appalachiensis shares several phenotypic characters with the recently elevated species canadensis (Rothschild & Jordan), preliminary mitochondrial DNA analysis indicates that appalachiensis is …

Name-Bearing Types And Taxonomic Synopsis Of Three Lycaenid Butterfly Taxa From Western Canada (Lepidoptera: Lycaenidae), Norbert G. Kondla, Crispin S. Guppy May 2002

Name-Bearing Types And Taxonomic Synopsis Of Three Lycaenid Butterfly Taxa From Western Canada (Lepidoptera: Lycaenidae), Norbert G. Kondla, Crispin S. Guppy

The Taxonomic Report of the International Lepidoptera Survey

We clarify which of two designated lectotypes of Chrysophanus florus Edwards, 1884 is valid. We also show that the putative holotype of Plebeius saepiolus insulanus Blackmore, 1920 is actually a lectotype. A valid neotype designation for Lycaena saepiolus amica Edwards, 1863 is provided. Publication dates are corrected and we also briefly review the various taxonomic interpretations and distributions that appear in the literature with respect to these taxa.

Diel And Seasonal Habitat Use By Red Shiner (Cyprinella Lutrensis), Shyi-Liang Yu, Edward J. Peters Jan 2002

Diel And Seasonal Habitat Use By Red Shiner (Cyprinella Lutrensis), Shyi-Liang Yu, Edward J. Peters

School of Natural Resources: Faculty Publications

Fish distribution and microhabitat use were quantified over a 24-h period 15 times from July 1988 to October 1990 at a site in the lower Platte River, Nebraska. The objectives of this study were to determine the effects of availability on habitat use by the red shiner (Cyprinella lutrensis) and to describe variations in red shiner use of depth, velocity, cover, and substrate by seasonal and diel periods. Day-night collections showed a difference in selection or avoidance of depths and substrates in summer. Red shiners selected depths of less than 30 cm during the night and fine substrate during the …

Clone Size Of Andropogon Gerardii Vitman (Big Bluestem) At Konza Prairie, Kansas, Kathleen H. Keeler, Charles F. Williams, Linda S. Vescio Jan 2002

Clone Size Of Andropogon Gerardii Vitman (Big Bluestem) At Konza Prairie, Kansas, Kathleen H. Keeler, Charles F. Williams, Linda S. Vescio

School of Biological Sciences: Faculty Publications

Clone size of plants of Andropogon gerardii from Konza Prairie Biological Station, Manhattan, Kansas was estimated from spatial patterns of genetic variation, using proteins detected by starch gel electrophoresis and DNA content (ploidy) measured by flow cytometry. Unique multi-locus protein banding patterns and differences in ploidy were used to exclude plants as members of the same clone. Individual clones averaged about 2 m in diameter and areas of prairie of 100 m2 were calculated to contain an average of 31.8 genetic individuals.

Morphological Variation Of Allocreadium Lobatum (Digenea: Allocreadiidae) In The Creek Chub, Semotilus Atromaculatus (Osteichthyes: Cyprinidae), In Nebraska, Usa, Monte S. Willis Jan 2002

Morphological Variation Of Allocreadium Lobatum (Digenea: Allocreadiidae) In The Creek Chub, Semotilus Atromaculatus (Osteichthyes: Cyprinidae), In Nebraska, Usa, Monte S. Willis

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Allocreadium lobatum Wallin 1909, a parasite of fresh-water fish, was originally described as having distinct lobate testes, and subsequent descriptions have left this original description unchanged. The present study quantifies the observation of distinctly non-lobate testes that could be categorized as round or asymmetrical in addition to the previously described lobate testes. Six hundred thirty-six A. lobatum were collected from 228 Semotilus atromaculatus over a 9 month period. Overall, 21.3%, 61.6%, and 16% were found to be round, asymmetrical, and lobate testes respectively (N = 1,071). Analysis of testis morphology found the increasing presence of lobate testis as …

Protostrongylus Stilesi (Nematoda: Protostrongylidae): Ecological Isolation And Putative Host-Switching Between Dall’S Sheep And Muskoxen In A Contact Zone, Eric P. Hoberg, Susan J. Kutz, John Nagy, Emily Jenkins, Brett Elkin, Marsha Branigan, Dorothy Cooley Jan 2002

Protostrongylus Stilesi (Nematoda: Protostrongylidae): Ecological Isolation And Putative Host-Switching Between Dall’S Sheep And Muskoxen In A Contact Zone, Eric P. Hoberg, Susan J. Kutz, John Nagy, Emily Jenkins, Brett Elkin, Marsha Branigan, Dorothy Cooley

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The occurrence of Protostrongylus stilesi in a population of introduced muskoxen, Ovibos moschatus wardi, on the Arctic Coastal Plain, Yukon Territory (YT) and Northwest Territories (NT), Canada, is consistent with a contemporary colonization event from Dall’s sheep, Ovis dalli dalli, which indicates that host specificity may be ecologically based and contextual for this parasite. Colonization of muskoxen by P. stilesi may be a predictable event in zones of sympatry with Dall’s sheep; exposure to infection may coincide with occupation of winter ranges of Dall’s sheep by muskoxen during the summer season. Disruption of contemporary ecological isolating barriers can …

Development Of The Muskox Lungworm, Umingmakstrongylus Pallikuukensis (Protostrongylidae), In Gastropods In The Arctic, Susan J. Kutz, Eric P. Hoberg, John Nishi, Lydden Polley

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Development of the muskox protostrongylid lungworm, Umingmakstrongylus pallikuukensis, in its slug intermediate host, Deroceras laeve, was investigated under field conditions in the Arctic. Every two weeks, from 19 June to 28 August 1997, groups of ten experimentally infected slugs were placed in tundra enclosures in a mesic sedge meadow near Kugluktuk, Nunavut, Canada. First-stage larvae (L1) infecting slugs on or before 17 July developed to third-stage larvae (L3) in 4–6 weeks. Intensity of L3 in slugs peaked at 6–8 weeks post infection (PI) and then progressively declined by 10, 12, and 48–50 weeks PI. Abundance of L3 in …
