Effects Of Supplemental Protein During Gestation And Grazing Sub-Irrigated Meadow During The Postpartum Interval On Pregnancy Rates Of Spring Calving Cows And Calf Growth, Leslie Aaron Stalker, Don C. Adams, Terry J. Klopfenstein Jan 2005

Effects Of Supplemental Protein During Gestation And Grazing Sub-Irrigated Meadow During The Postpartum Interval On Pregnancy Rates Of Spring Calving Cows And Calf Growth, Leslie Aaron Stalker, Don C. Adams, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A two year experiment evaluated the influence of supplemental protein during the last trimester of gestation and grazing sub-irrigated meadow during the postpartum interval on pregnancy rates and calf growth in a March calving production system. Supplemental protein during the last trimester did not improve subsequent pregnancy rate but resulted in increased carcass weight. Allowing cows to graze sub-irrigated meadow during the postpartum interval improved pregnancy rates but did not change steer performance in the feedlot. Feeding supplemental protein during the last trimester of gestation and allowing cows to graze sub-irrigated meadow were both economical methods of improving production.

Redescription And New Host Record Of Eimeria Serbica From The Caucasian Tree Squirrel, Sciurus Anomalus, From Turkey, Lee Couch, Atilla Arslan, Donald W. Duszynski

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

Fecal samples from 20 Caucasian tree squirrels, Sciurus anomalus (Gmelin, 1778) Güldenstaedt, 1785, were collected in Turkey during February and March, 2004, and all 20 were infected with a single species of coccidia, Eimeria serbica. Sporulated oocysts are ellipsoidal, 27.5 × 17.5 (21–34 × 15–20) with a length:width ratio (L/W) of 1.6 (1.4–1.8); they lack a micropyle and oocyst residuum, but 0–2 polar granules may be present. Sporocysts are ellipsoidal, 11.9 × 6.9 (10.5–14 × 6–7.5) with a L/W of 1.7 (1.5–2.1); a Stieda body and sporocyst residuum are present.

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In the present paper, we describe the community structure, species diversity, population density, and the character of distribution of soil microarthropods of the Gobi Gurvan Saykhan mountains. In total 45 species of soil microarthropods belonging to 37 genera and 24 families were identified. Twenty-seven species of soil microarthropods belonging to 25 genera and 20 families were found in the Züün Saykhan, 31 species belonging to 27 genera and 19 families in the Dund Saykhan. Oribatid mites are the dominant group (35 species = 77.8% of total species richness), while mesostigmatid mites account for 7 species (15.6 %). Other groups are …


Die Parasitierung Der Luzerne-Blattschneiderbiene, Megachile Rotundata (Hymenoptera: Megachilidae), Durch Physocephala Pusilla (Diptera: Conopidae) In Der Mongolei = Parasitization Of The Alfalfa Leaf-Cutter Bee, Megachile Rotundata (Hymenoptera: Megachilidae), By Physocephala Pusilla (Diptera: Conopidae) In Mongolia, Karsten Seidelmann Jan 2005

Die Parasitierung Der Luzerne-Blattschneiderbiene, Megachile Rotundata (Hymenoptera: Megachilidae), Durch Physocephala Pusilla (Diptera: Conopidae) In Der Mongolei = Parasitization Of The Alfalfa Leaf-Cutter Bee, Megachile Rotundata (Hymenoptera: Megachilidae), By Physocephala Pusilla (Diptera: Conopidae) In Mongolia, Karsten Seidelmann

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Physocephala pusilla Meigen (Diptera: Conopidae) was found to be a dangerous endoparasitoid of the alfalfa leafcutter bee Megachile rotundata F. (Hymenoptera: Megachilidae) in Mongolia. The conopid fly parasitizes adults and causes their early death. In 1989 and 1990, 16% and 15% respectively of the M. rotundata females were found dead in front of the bee shelter. However, the number of bees (females and males) dying in the field is unknown. These bees cause a contamination of the alfalfa fields due to an increase of the conopid population. Therefore, Ph. pusilla becomes a serious problem for the management of M. rotundata …


Biodiversity And Ecology Of Soil Oribatid Mites (Acari: Oribatida) In The Grassland Habitats Of Eastern Mongolia, Badamdorj Bayartogtokh Jan 2005

Biodiversity And Ecology Of Soil Oribatid Mites (Acari: Oribatida) In The Grassland Habitats Of Eastern Mongolia, Badamdorj Bayartogtokh

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Composition, abundance, distribution, and diversity of oribatid mite communities were investigated at five study areas in Eastern Mongolia. A total of 88 species of oribatid mites were recorded from the studied areas. The largest number of species (51 spp.) was found in the habitats of river valleys, while the plain steppe which covers the largest area contained the lowest species richness (24 spp.). Three other sub-regions with similar landscape types show approximately the same species richness (39 to 45 spp.), although they are located relatively far from each other. The oribatid mite faunas of all sub-regions were essentially similar to …


Types Of Areas And The Origin Of Black Flies Fauna In Mongolia (Diptera: Simuliidae), Josef Halgoš Jan 2005

Types Of Areas And The Origin Of Black Flies Fauna In Mongolia (Diptera: Simuliidae), Josef Halgoš

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The survey of Mongolian Black Flies species (Diptera: Simuliidae) is given in the presented work. The classification based on Emelyanov (1974) and Gorodkov (1984) appeared to be as most advantageous one. Black Flies species found on the Mongolian territory up to now were classified according to the character of their distribution among 5 groups: Holoarctic species (7 species), Eurasian (15), Eastern Palaearctic (20), Turanian-Mediterranean (7), Mongolian endemic species (8). Individual groups are divided according to the type of area into smaller subgroups. The zoogeographical analysis has shown big similarity with Black Flies zoogeography in Siberia and Far East (in percentage …

Parasites Of The American White Pelican, Robin M. Overstreet, Stephen S. Curran Jan 2005

Parasites Of The American White Pelican, Robin M. Overstreet, Stephen S. Curran

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

Metazoan symbionts, including parasites, infecting the American white pelican (AWP) Pelecanus erythrorhynchos comprise a list of 75 species, 7 of which are new host records. Several new geographic records are also presented, but generally these have a low value because of the migratory nature of the bird. Evidence suggests that some parasites, mostly flies and other arthropods but also nematodes and digeneans, produce detrimental behavioral or pathologic changes in the AWP. Some of the arthropods transmit microbial agents to the pelican. Two digeneans that have the AWP as a definitive host harm and even kill their catfish intermediate host, especially …


The Pathologic Copepod Phrixocephalus Cincinnatus (Copepoda: Pennellidae) In The Eye Of Arrowtooth Flounder, Atherestes Stomias, And Rex Sole, Glyptocephalus Zachirus, From British Columbia, Reginald B. Blaylock, Robin M. Overstreet, Alexandra B. Morton Jan 2005

The Pathologic Copepod Phrixocephalus Cincinnatus (Copepoda: Pennellidae) In The Eye Of Arrowtooth Flounder, Atherestes Stomias, And Rex Sole, Glyptocephalus Zachirus, From British Columbia, Reginald B. Blaylock, Robin M. Overstreet, Alexandra B. Morton

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

We report Phrixocephalus cincinnatus, a pennellid copepod infecting the eyes of flatfishes, from a single specimen of rex sole, Glyptocephalus zachirus, for the first time. In the typical host, the arrowtooth flounder, Atherestes stomias, the parasite occurred commonly in sampled populations from the Broughton Archipelago in British Columbia, infected primarily the right eye of the flounder, and on only one occasion presented more than two parasites per eye. The copepod attached to the choroid layer and ramified throughout the posterior compartment of the eye, resulting in the disruption of the retina and probably impairing host vision. Inflammation …


Global Warming Is Changing The Dynamics Of Arctic Host-Parasite Systems, S. J. Kutz, Eric P. Hoberg, L. Polley, E. J. Jenkins Jan 2005

Global Warming Is Changing The Dynamics Of Arctic Host-Parasite Systems, S. J. Kutz, Eric P. Hoberg, L. Polley, E. J. Jenkins

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

Global climate change is altering the ecology of infectious agents and driving the emergence of disease in people, domestic animals, and wildlife. We present a novel, empirically based, predictive model for the impact of climate warming on development rates and availability of an important parasitic nematode of muskoxen in the Canadian Arctic, a region that is particularly vulnerable to climate change. Using this model, we show that warming in the Arctic may have already radically altered the transmission dynamics of this parasite, escalating infection pressure for muskoxen, and that this trend is expected to continue. This work establishes a foundation …

Trichinella Pseudospiralis From A Wild Pig In Texas, H. Ray Gamble, E. Pozio, J. Ralph Lichtenfels, D. S. Zarlenga, D. E. Hill

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

In December 2001, the routine inspection of a wild boar intended for human consumption revealed the presence of Trichinella ssp. larvae. Biological, morphological and genetic analyses demonstrated the parasite to be Trichinella pseudospiralis. This is the second report of T. pseudospiralis in the United States and the first report of the parasite in a food animal species in the U.S.


Caudal Polymorphism And Cephalic Morphology Among First-Stage Larvae Of Parelaphostrongylus Odocoilei (Protostrongylidae: Elaphostrongylinae) In Dall’S Sheep From The Mackenzie Mountains, Canada, Eric P. Hoberg, Emily J. Jenkins, Benjamin Rosenthal, Mayee Wong, Eric F. Erbe, Susan J. Kutz, Lydden Polley Jan 2005

Caudal Polymorphism And Cephalic Morphology Among First-Stage Larvae Of Parelaphostrongylus Odocoilei (Protostrongylidae: Elaphostrongylinae) In Dall’S Sheep From The Mackenzie Mountains, Canada, Eric P. Hoberg, Emily J. Jenkins, Benjamin Rosenthal, Mayee Wong, Eric F. Erbe, Susan J. Kutz, Lydden Polley

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

We demonstrate polymorphism in the structure of the tail among first-stage larvae of Parelaphostrongylus odocoilei (Protostrongylidae). Two distinct larvae, both with a characteristic dorsal spine, include (1) a morphotype with a kinked conical tail marked by three distinct transverse folds or joints and a symmetrical terminal tail spike and (2) a morphotype with a digitate terminal region lacking folds or joints and with an asymmetrical, subterminal tail spike. These divergent larval forms had been postulated as perhaps representing distinct species of elaphostrongyline nematodes. Application of a multilocus approach using ITS-2 sequences from the nuclear genome and COX-II sequences from the …

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

An intensive survey of ectoparasitic arthropods associated with small mammals in upland forests near Manaus, Brazil, provides information on the taxonomy and host distribution of laelapine mites in the Amazonian Region. We identified 5 genera and 21 species of these mites by comparisonw ith representativem useum specimens, the taxonomic literature, and, when possible, the original type specimens. These mites are host specific, with associations ranging from strict monoxeny (18 species) to oligoxeny (1 species) and pleioxeny (2 species). Marsupials were infested with species of Androlaelaps, echimyid rodents with Tur, and sigmodontine rodents with Gigantolaelaps, Laelaps, and Mysolaelaps. Androlaelaps bergalloi …


Faunal Survey Of Streblid Flies (Diptera: Streblidae) Associated With Bats In Paraguay, Carl W. Dick, Donald Gettinger Jan 2005

Faunal Survey Of Streblid Flies (Diptera: Streblidae) Associated With Bats In Paraguay, Carl W. Dick, Donald Gettinger

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

An extensive survey of the ectoparasites infesting bats in Paraguay provides information regarding the taxonomy and host distribution of streblid bat flies at a geographic interface between subtropical and temperate habitats. Five families of bats representing 45 species, including Molossidae (5 genera and 15 species), Natalidae (1 genus and 1 species), Phyllostomidae (11 genera and 15 species), Noctilionidae (1 genus and 2 species), and Vespertilionidae (4 genera and 12 species) were collected from 24 localities across Paraguay and sampled for ectoparasites. In total, 2,467 bat flies were collected, representing 11 genera and 31 nominal species of Streblidae, of which 6 …


Hesperoctenes Fumarius (Hemiptera: Polyctenidae) Infesting Molossus Rufus (Chiroptera: Molossidae) In Southeastern Brazil, Carlos E. L. Esbérard, Andrea C. Jesus, Adarene G. Motta, Helena G. Bergallo, Donald Gettinger Jan 2005

Hesperoctenes Fumarius (Hemiptera: Polyctenidae) Infesting Molossus Rufus (Chiroptera: Molossidae) In Southeastern Brazil, Carlos E. L. Esbérard, Andrea C. Jesus, Adarene G. Motta, Helena G. Bergallo, Donald Gettinger

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

We analyzed the prevalence. intensity. and medium density of parasitism of Hesperoctenes fumarius infesting Molossus rufus in natural (hollow trees) and anthropogenic roosts (attics) in southeastern Brazil. The prevalence and intensity of infestations were higher in the hollow trees than in the attic roosts. We also noted a relationship between the amount of space available within the roost and the infestation levels of H. fumarius. One advantage of roosting in larger. often manmade. refuges may be the reduction in ectoparasite infestations.


A New Species Of Skrjabingylus Petrov, 1927 (Nematoda: Metastrongyloidea) From The Frontal Sinuses Of The Hooded Skunk, Mephitis Macroura (Mustelidae), Ramon A. Carreno, Kathryn E. Reif, Steven A. Nadler Jan 2005

A New Species Of Skrjabingylus Petrov, 1927 (Nematoda: Metastrongyloidea) From The Frontal Sinuses Of The Hooded Skunk, Mephitis Macroura (Mustelidae), Ramon A. Carreno, Kathryn E. Reif, Steven A. Nadler

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

Skrjabingylus santaceciliae n. sp. is described based on specimens from the frontal sinuses of a hooded skunk, Mephitis macroura, collected from the Area de Conservación Guanacaste, Costa Rica. Skrjabingylus santaceciliae n. sp. differs from the other 5 species in the genus in having pointed spicule tips that lack a rounded or lobed formation and by lacking a prominent distal projection at the tail tip. Morphometric comparisons show that S. santaceciliae n. sp. is much smaller than the only other valid species from Mephitis, Skrjabingylus chitwoodorum Hill, 1939. Likewise, morphometric comparisons also distinguish S. santaceciliae n. sp. from other described Skrjabingylus …


Systematics Of Mesocestoides (Cestoda: Mesocestoididae): Evaluation Of Molecular And Morphological Variation Among Isolates, Kerry A. Padgett, Steven A. Nadler, Linda Munson, Ben Sacks, Walter M. Boyce Jan 2005

Systematics Of Mesocestoides (Cestoda: Mesocestoididae): Evaluation Of Molecular And Morphological Variation Among Isolates, Kerry A. Padgett, Steven A. Nadler, Linda Munson, Ben Sacks, Walter M. Boyce

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

A hypothesis-based framework was used to test if 3 genetic strains of Mesocestoides (clades A, B, and C) are distinct evolutionary lineages, thereby supporting their delimitation as species. For comparative purposes, 3 established cestode species, Taenia pisiformis, Taenia serialis, and Taenia crassiceps were assessed using the same methods. Sequence data from mitochondrial rDNA (12S) and the second internal transcribed spacer of nuclear rDNA (ITS-2) revealed derived (autapomorphic) characters for lineages representing clade A (n = 6 autapomorphies), clade B (n = 4), and clade C (n = 9) as well as T. pisiformis (n = 15) and T. serialis …


Pseudostertagia Bullosa (Nematoda: Trichostrongyloidea) In Artiodactyl Hosts From North America: Redescription And Comments On Systematics, Eric P. Hoberg, A. Abrams Jan 2005

Pseudostertagia Bullosa (Nematoda: Trichostrongyloidea) In Artiodactyl Hosts From North America: Redescription And Comments On Systematics, Eric P. Hoberg, A. Abrams

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

A relationship for Pseudostertagia bullosa within the trichostrongyloids has been enigmatic or unresolved. Studies of the synlophe in males and females of P. bullosa revealed a tapering system anterior to the deirids and a pattern of parallel ridges extending to near the caudal extremity in both lateral and median fields. Structurally, the synlophe differs considerably from that seen among the Cooperiinae and exhibits homoplasy with respect to ridge systems among some Ostertagiinae. Other structural characters due to symplesiomorphy, homoplasy or because they represent autapomorphies do not serve to reveal the putative relationships for P. bullosa with other trichostrongyloids. Although somewhat …

Molecular Phylogenetics And Diagnosis Of Anisakis, Pseudoterranova, And Contracaecum From Northern Pacific Marine Mammals, Steven A. Nadler, Stefano D'Amelio, Murray D. Dailey, Lia Paggi, Sandra Siu, Jusy A. Sakanari

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

Individual specimens of Anisakis, Pseudoterranova, and Contracaecum collected from marine mammals inhabiting northern Pacific waters were used for comparative diagnostic and molecular phylogenetic analyses. Forty-eight new sequences were obtained for this study of 14 Anisakis taxa, 8 Pseudoterranova taxa, 4 Contracaecum taxa, and 4 outgroup species. Partial 28S (LSU) and complete internal transcribed spacer (ITS-1, 5.8S, ITS-2) ribosomal DNA was amplified by the polymerase chain reaction and sequenced. Sequences of ITS indicated that Pseudoterranova specimens from Zalophus californianus (California sea lion), Mirounga angustirostris (northern elephant seal), Phoca vitulina (harbor seal), Enhydra lutris (sea otter), and Eumetopias jubatus (Steller’s …


Possible Recent Range Expansion Of Alcataenia Longicervica (Eucestoda: Dilepididae) Parasitic In Murres Uria Spp. (Alcidae) Into The North Atlantic [Short Communications], Sabir B. Muzaffar, Eric P. Hoberg, Ian L. Jones Jan 2005

Possible Recent Range Expansion Of Alcataenia Longicervica (Eucestoda: Dilepididae) Parasitic In Murres Uria Spp. (Alcidae) Into The North Atlantic [Short Communications], Sabir B. Muzaffar, Eric P. Hoberg, Ian L. Jones

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

A wide range of helminths has been recorded from murres Uria spp. (Threlfall 1971, reviewed by Hoberg 1984a, Muzaffar & Jones 2004). Of the cyclophyllidean cestodes that parasitize murres, the genus Alcataenia Spasskaya 1971 (Dilepididae) is represented by ten species, eight of which are restricted and specific to the auks; the other two species occur in gulls (Laridae). The intermediate hosts of Alcataenia are euphausiid crustaceans such as species of Thysanoessa (Shimazu 1975), which also form an important dietary component of breeding and wintering murres, particularly Thick-billed Murres Uria lomvia (Gaston & Noble 1985, Birkhead & Nettleship 1987, Elliot et …

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

Recently, the protostrongylid nematode Parelaphostrongylus odocoilei has been reported in a new host species, thinhorn sheep (Ovis dalli). For the first time, we completed the life cycle of P. odocoilei in three Stone’s sheep (O. dalli stonei) and two thinhorn hybrids (O. dalli stonei × O. dalli dalli), each infected with 200 third-stage larvae from slugs (Deroceras laeve). The prepatent period ranged from 68 days to 74 days, and shedding of first-stage larvae (L1) peaked at >10,000 L1 per gram of feces between 90 and 110 days postinfection. A total of 75, …


Homologous And Heterologous Reconstitution Of Golgi To Chloroplast Transport And Protein Import Into The Complex Chloroplasts Of Euglena, Silvia Sláviková, Rostislav Vacula, Zhiwei Fang, Tomoko Ehara, Tetsuaki Osafune, Steven D. Schwartzbach Jan 2005

Homologous And Heterologous Reconstitution Of Golgi To Chloroplast Transport And Protein Import Into The Complex Chloroplasts Of Euglena, Silvia Sláviková, Rostislav Vacula, Zhiwei Fang, Tomoko Ehara, Tetsuaki Osafune, Steven D. Schwartzbach

School of Biological Sciences: Faculty Publications

Euglena complex chloroplasts evolved through secondary endosymbiosis between a phagotrophic trypanosome host and eukaryotic algal endosymbiont. Cytoplasmically synthesized chloroplast proteins are transported in vesicles as integral membrane proteins from the ER to the Golgi apparatus to the Euglena chloroplast. Euglena chloroplast preprotein pre-sequences contain a functional N-terminal ER-targeting signal peptide and a domain having characteristics of a higher plant chloroplast targeting transit peptide, which contains a hydrophobic stop-transfer membrane anchor sequence that anchors the precursor in the vesicle membrane. Pulse-chase subcellular fractionation studies showed that 35S-labeled precursor to the light harvesting chlorophyll a/b binding protein accumulated in the Golgi …


First Record Of Drosophila Parthenogenetica And D. Neomorpha, Cardini Group, Heed, 1962 (Drosophila, Drosophilidae), In Brazil, Daniela Cristina De Toni, Jennifer A. Brisson, Paulo R. P. Hofmann, Marlucia Martins, Hope Hollocher Jan 2005

First Record Of Drosophila Parthenogenetica And D. Neomorpha, Cardini Group, Heed, 1962 (Drosophila, Drosophilidae), In Brazil, Daniela Cristina De Toni, Jennifer A. Brisson, Paulo R. P. Hofmann, Marlucia Martins, Hope Hollocher

The group is characterized by medium-sized flies with a shiny thorax (Vilela et al., 2002). Different species of the group display different abdominal pigmentation patterns …


First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles Jan 2005

First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles

The Prairie Naturalist

The evening bat (Nycticeius humeralis) occurs throughout the eastern and southeastern United States and into extreme northeastern Mexico, approximately 42° to 18° N latitude (Watkins and Shump 1981). Although records of females are common, records of adult male evening bats are rare in the northern portion of the species range (Watkins 1969, Watkins 1972). Jones et al. (1967) suggested that adult males might not accompany females to at least some parts of the parturient range. As part of a larger study (Davis 2003) we surveyed bats on Fort Leavenworth Military Reservation (FLMR), Leavenworth County, Kansas in July 2002 …


Efficacy Of Translocations For Restoring Populations Of Black-Tailed Prairie Dogs, Jo Ann L. D. Dullum, Kerry R. Foresman, Marc R. Matchett Jan 2005

Efficacy Of Translocations For Restoring Populations Of Black-Tailed Prairie Dogs, Jo Ann L. D. Dullum, Kerry R. Foresman, Marc R. Matchett

United States Fish and Wildlife: Staff Publications

We evaluated translocation as a method to promote recovery of black-tailed prairie dogs (Cynomys ludovicianus) after plague-induced population declines in colonies at the Charles M. Russell National Wildlife Refuge, Montana. We translocated prairie dogs in June of 1999 and evaluated the effects of translocation on colony area 1 year and 4 years later. We also assessed effects of release group size and estimated rates of population growth and survival. Initial size of experimental colonies was categorized as inactive (0 ha), small (0.1-2.0 ha), or large (2.0-6.6 ha); numbers of prairie dogs translocated to each colony size class were …


Endangered And Threatened Wildlife And Plants; Determination Of Endangered Status For The Salt Creek Tiger Beetle (Cicindela Nevadica Lincolniana) Jan 2005

Endangered And Threatened Wildlife And Plants; Determination Of Endangered Status For The Salt Creek Tiger Beetle (Cicindela Nevadica Lincolniana)

United States Fish and Wildlife: Staff Publications

We, the U.S. Fish and Wildlife Service (Service), determine endangered status for the Salt Creek tiger beetle (Cicindela nevadica lincolniana), pursuant to the Endangered Species Act (Act) of 1973, as amended (Act). This species is endemic to the saline wetlands of eastern Nebraska (NE) and associated streams in the northern third of Lancaster County and southern margin of Saunders County. Only three small populations of this subspecies remain, and the known adult population size in 2005 was only 153 individuals. This final rule extends Federal protection and recovery provisions of the Act to the Salt Creek tiger beetle.
