The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin 2017 Marshall University

The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin

Euscorpius

We report the remnants of five new scorpion specimens discovered dead in Levana Cave in Israel in December 2015. We confirm that they belong to the relict scorpion Akrav israchanani Levy, 2007 (Akravidae), famously described from the neighboring Ayyalon Cave, also from dead specimens. The details of morphology of the new specimens are given; they match completely the characters of A. israchanani redescribed by Fet, Soleglad & Zonstein (2011). This second record indicates a wider distribution of this unique cave scorpion, which, however, is extinct in both caves. There is still no evidence that live populations of this species exist.

Some Factors Influencing Populations Of The European Corn Borer, Ostrinia Nubilalis (Hubner) In The North Central States: Resistance Of Corn, Time Of Planting And Weather Conditions Part Ii, 1958-1962, A. N. Sparks, H. C. Chiang, C. A. Triplehorn, W. D. Guthrie, T. A. Brindley

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

A cooperative project was conducted by the agricultural experiment stations of Iowa, Minnesota and Ohio and the U. S. Department of Agriculture to study the effects of weather, planting date and resistant hybrids as factors influencing populations of the European com borer, Ostrinia nubilalis (Hübner). Identical studies were carried out at Ankeny, Iowa; Waseca, Minnesota; and Wooster, Ohio, during a 10-year period, 1953-1962.

The first 4 years of the study (1953-56) were reported by Everett et al. (1958). The work reported herein is a companion bulletin to the Everett et al. (1958) publication and deals with the results of experiments ...


Mountain Plover Nest In Kimball County, Stephen J. Dinsmore 2017 Midcontinent Ecological Science Center

Mountain Plover Nest In Kimball County, Stephen J. Dinsmore

Stephen J Dinsmore

On 18 May 1995 I observed two adult Mountain Plovers 5 mi west and 1.25 mi north of Bushnell in southwest Kimball county. The birds were in an area of short-grass prairie interspersed with clumps of prickly pear and bare ground. I observed both birds almost continuously from 1-2 p.m. MDT. The first bird was along the road south of the fenceline, just after the road climbs on top of the plateau. The second bird was about 0.1 mi to the north on the west side of the road. Both birds were medium-sized, plain shorebirds, similar in ...


Long-Tailed Jaegers In Western Nebraska, Stephen J. Dinsmore 2017 Selected Works

Long-Tailed Jaegers In Western Nebraska, Stephen J. Dinsmore

Stephen J Dinsmore

The Long-tailed Jaeger is an accidental migrant in Nebraska with just one accepted record through the mid-1990s. Based on records from adjacent states, especially Colorado (Andrews and Righter 1992) and Wyoming (Faulkner 2010), the species is probably more frequent than these records indicate, and its status is further complicated by possible confusion with Pomarine and Parasitic jaegers. In this article I report details of four records of Long-tailed Jaegers in western Nebraska and comment on the species' identification and status in the state.

Notes On Bird Sightings In Nebraska March 1997, Ruth C. Green, Alice Kenitz, Joel G. Jorgensen, Stephen J. Dinsmore

Stephen J Dinsmore

Albino Eastern Bluebirds. On 24 July 1996, I banded two totally white Eastern Bluebirds in Sarpy County, Nebraska. These two birds were in a nest with two other normally plumaged siblings. They were not only white-plumaged, their feet and bills were white and the eyes were a pinkish-red. They were just as well developed as the two normal birds and were ready to fledge, which they did the following day. I believe these birds fit the description of total albinism as defined by John K. Terres in The Audubon Encyclopedia of North American Birds. He defines total albinism as the ...


Hyperactivity, Blood Lactic Acid And Mortality In Channel Catfish, Charles W. Caillouet Jr. 2017 University of Southwestern Louisiana

Hyperactivity, Blood Lactic Acid And Mortality In Channel Catfish, Charles W. Caillouet Jr.

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

Mortality in submature channel catfish, Ictalurus punctatus (Rafinesque), caught in the Mississippi River and stocked in Iowa streams and ponds, led to this investigation in 1961-1963. The major findings can be summarized as follows:

The mean concentration of lactic acid in the blood of unexercised channel catfish varied from 2.3 to 7.6 mg/100 ml of whole blood. That of fish subjected individually to forced exercise varied from 21.1 to 44.1 mg/100 ml after 5 minutes of exercise and from 59.1 to 67.6 mg/100 ml after 15 minutes of exercise. A lower ...


Description Of A Pathologic White-Tailed Deer (Odocoileus Virginianus) Mandible From Central Georgia, Patrick M. Powers, Alfred J. Mead 2017 Georgia College and State University

Description Of A Pathologic White-Tailed Deer (Odocoileus Virginianus) Mandible From Central Georgia, Patrick M. Powers, Alfred J. Mead

Georgia Journal of Science

A pathologic mandible was observed in a male white-tailed deer (Odocoileus virginianus) harvested in central Georgia during the 2015 fall hunting season. The deer was approximately four and a half years of age and displayed no outward indication of injury or evidence of irregular tooth attrition at the time of death. Upon soft tissue removal, the mandible displayed signs of premortem trauma. The pathology was consistent with secondary bone deposition associated with bone breakage. The nature of the fracture suggests that it may have been caused by antler impact during male-to-male sparring. A physical examination of 621 white-tailed deer mandibles ...


Biology And Possible Control Of Nuisance Caddisflies Of The Upper Mississippi River, Calvin R. Fremling 2017 Winona State College

Biology And Possible Control Of Nuisance Caddisflies Of The Upper Mississippi River, Calvin R. Fremling

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

The principal nuisance species of caddisflies at Keokuk, Iowa, are Hydropsyche orris Ross, Cheumatopsyche campyla Ross and Potamyia flava (Hagen), all members of the family Hydropsychidae (Order Trichoptera). The larvae of these species require considerable water current so that food may be carried into the nets which they construct upon submerged rocks and other silt-free structures. Keokuk lies along the tailwaters of the largest dam on the Upper Mississippi River, and the current and subsequent lack of silting create a large area which is favorable for hydropsychid larval habitation. Consequently, Keokuk is host to more caddisflies than the other river ...


Biology Of A Large Mayfly, Hexagenia Bilineata (Say), Of The Upper Mississippi River, Calvin R. Fremling 2017 Winona State College

Biology Of A Large Mayfly, Hexagenia Bilineata (Say), Of The Upper Mississippi River, Calvin R. Fremling

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

Hexagenia bilineata (Say) and Hexagenia limbata ( Serville) create nuisance problems by their sheer numbers in many cities along the Mississippi River. They also constitute a navigation hazard and may cause allergies.

H. bilineata is generally more abundant than H. limbata on the Upper Mississippi River, but H. limbata becomes increasingly abundant northward. The absence of intermediate-sized nymphs in late summer indicates that H. bilineata completes a generation in 1 year in the Keokuk area. H. bilineata nymphs live in burrows in the river bottom and are most abundant in impounded areas where there is little current and where the river ...


The Effects Of Fluoride Ions On Neuromuscular Activity And Regeneration In Dugesia Tigrina, John Williams Jr. 2017 Albany State University

The Effects Of Fluoride Ions On Neuromuscular Activity And Regeneration In Dugesia Tigrina, John Williams Jr.

Georgia Journal of Science

Fluoride ions have been implicated in numerous nervous system pathologies, though the association of these ions with these conditions has been controversial. The purpose of this research is to determine the effects that fluoride ions have on the nervous system development and function in planarians as a simple model for fluoride-nervous system interactions. In the first set of experiments, planarians were exposed to one of four concentrations of sodium fluoride: 0 mM, 1 mM, 1 mM, and 5 mM. In the second set of experiments, planarians were bisected and exposed to 1 mM of NaCl and NaF for regeneration purposes ...


Life History Of The White Bass, Lepibema Chrysops (Rafinesque), Of Spirit Lake, Iowa, William F. Sigler 2017 Utah State Agricultural College, Logan

Life History Of The White Bass, Lepibema Chrysops (Rafinesque), Of Spirit Lake, Iowa, William F. Sigler

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

The white bass were probably originally stocked in Spirit Lake, northwestern Iowa, in the last 50 years and were not native to these waters. The numbers have shown great fluctuations over the years. The field work for the present study covered the period 1941 to 1946.

Spirit Lake is a shallow, rich, hard water, eutrophic lake not exceeding 23 feet in depth. Potamogeton richardsonii and Scirpus acutus are the dominant deep-water plants. In general, young pan and game fish amounted to a very large percentage of all of the small fish in the lake during the years 1941, 1942, 1943 ...


Comparative Analysis Of Red Fox Feeding Trends On Two Central Iowa Areas, Thos G. Scott 2017 U.S.D.I.

Comparative Analysis Of Red Fox Feeding Trends On Two Central Iowa Areas, Thos G. Scott

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

Progress toward an understanding of the meaning of predation is sometimes obtained by comparing the predator's feeding trends in markedly different habitats. Data collected in Iowa in 1940 and 1941 make such a comparison possible for the northern plains red fox (Vulpes regalis Merriam). A continuous investigation of the food coactions of red foxes was made on the Moingona Fox Range from June 1938 to May 1941 (Scott, 15). A similar study was undertaken on the Wall Lake Area in June 1940 and continued to October 1941, when it was interrupted by World War II. Thus, observations were being ...


An Analysis Of Mink Predation Upon Muskrats In Northcentral United States, Paul L. Errington 2017 Iowa State College

An Analysis Of Mink Predation Upon Muskrats In Northcentral United States, Paul L. Errington

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

The present analysis is based on data first acquired incidental to personal fur-trapping (principally in South Dakota, 1915-28), later as a product of intensive year-to-year field researches in central and northern Iowa, 1934-42. In the intensive phases of the investigations, particular efforts were made to inquire into the mechanics of predation suffered by the muskrat at different densities, under different environmental conditions, and at different seasons.

It was found that strangeness of environment, intraspecific intolerance, and drouth were especially important in predisposing muskrats of north-central United States to predation, as by minks; and that kinds and numbers of wild predators ...


Development Of A Bob-White Management Area In Southern Iowa, Earl Sanders 2017 Iowa State College

Development Of A Bob-White Management Area In Southern Iowa, Earl Sanders

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

An experimental bob-white management area was divided into two parts, the northern part of which was designated as the pay-shooting area because the farmers were permitted to charge $1 per man-day for hunting privileges. The southern part was designated as a free-shooting area because the farmers were not permitted to charge for hunting, but instead were paid 10 cents an acre by the Iowa State Conservation Commission in 1936 and 1937. Both areas were to carry out identical, recommended game management practices.

Designated game management practices in 1936 included: (1) Planting sorghum and Korean lespedeza; (2) setting out trees; (3 ...


Ecology And Management Of The Mourning Dove, Zenaidura Macroura (Linn.), In Cass County, Iowa, H. Elliott McClure 2017 Iowa State College

Ecology And Management Of The Mourning Dove, Zenaidura Macroura (Linn.), In Cass County, Iowa, H. Elliott Mcclure

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

Decrease of the mourning dove, an important game bird of the United States, has been noted recently in eastern and southern states. In Iowa, the dove is among the commonest of breeding birds, and observations in Cass County, Iowa, during 30 months of 1938, 1939 and 1940 revealed that the county production was high, averaging an estimated 200,000 young yearly from 73,000 adults. About 2 percent of the summer residents is believed to have wintered in the county.

Detailed investigations at Lewis, at 14 farmyards and at 6 other habitat types, brought under observation nearly 4,000 nests ...


Microananteroides Mariachiarae Rossi Et Lourenço, 2015 Is A Junior Synonym Of Akentrobuthus Atakora Vignoli Et Prendini, 2008 (Scorpiones: Buthidae), František Kovařík, Rolando Teruel, Graeme Lowe 2017 Museo de Historia Natural “Tomás Romay”

Microananteroides Mariachiarae Rossi Et Lourenço, 2015 Is A Junior Synonym Of Akentrobuthus Atakora Vignoli Et Prendini, 2008 (Scorpiones: Buthidae), František Kovařík, Rolando Teruel, Graeme Lowe

Euscorpius

The African monotypic scorpion genus Microananteroides Rossi et Lourenço, 2015 and its single species M. mariachiarae Rossi et Lourenço, 2015, from Ghana, are herein demonstrated to be junior synonyms, respectively, of Akentrobuthus Lamoral, 1976 and A. atakora Vignoli et Prendini, 2008 from neighboring Benin. We provide detailed high-resolution color photographs of the holotype of M. mariachiarae and further show its real tri-chobothrial pattern, which was incorrectly depicted in the original description.


The Great Horned Owl And Its Prey In North-Central United States, Paul L. Errington, Frances Hamerstrom, F. N. Hamerstrom Jr. 2017 Iowa State College

The Great Horned Owl And Its Prey In North-Central United States, Paul L. Errington, Frances Hamerstrom, F. N. Hamerstrom Jr.

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

Along with other predatory species, the great horned owl has been studied in north-central United States, particularly in Iowa and southern Wisconsin localities in which ecological research upon certain prey types has been carried on contemporaneously. After investigation by field and laboratory methods involving experimentation with captive horned owls and observation in nature, it became obvious that the mass data on feeding trends required by the program could be best obtained through pellet studies supplemented by whatever additional techniques would yield information.

The horned owl food habits data upon which this bulletin is partly based were gathered largely between 1930 ...


Complements To The Taxonomy Of Some Amazonian Scorpions (Scorpiones: Buthidae), Rolando Teruel, František Kovařík, Graeme Lowe, Stefan Friedrich 2017 Museo de Historia Natural “Tomás Romay”

Complements To The Taxonomy Of Some Amazonian Scorpions (Scorpiones: Buthidae), Rolando Teruel, František Kovařík, Graeme Lowe, Stefan Friedrich

Euscorpius

We describe and illustrate in detail the previously unknown adult male of Ananteris ashaninka Kovařík, Teruel, Lowe et Friedrich, 2015, based upon a specimen recently captured at the type locality. In addition, the taxonomic status of three Amazonian species of the genus Tityus C. L. Koch, 1836, is reevaluated and all are restored from unjustified synonymies: Tityus carolineae Kovařík, Teruel, Cozijn et Seiter, 2013, Tityus dillerorum Kovařík, Teruel, Lowe et Friedrich, 2015, and Tityus wachteli Kovařík, Teruel, Lowe et Friedrich, 2015.


Investigation Of The Impact Of Increased Dietary Insoluble Fiber Through The Feeding Of Distillers Dried Grains With Solubles (Ddgs) On The Incidence And Severity Of Brachyspira-Associated Colitis In Pigs, Bailey Lauren Wilberts, Paulo Elias Arruda, Joann M. Kinyon, Timothy S. Frana, Chong Wang, Drew Robert Magstadt, Darin M. Madson, John F. Patience, Eric Ryan Burrough 2017 Iowa State University

Investigation Of The Impact Of Increased Dietary Insoluble Fiber Through The Feeding Of Distillers Dried Grains With Solubles (Ddgs) On The Incidence And Severity Of Brachyspira-Associated Colitis In Pigs, Bailey Lauren Wilberts, Paulo Elias Arruda, Joann M. Kinyon, Timothy S. Frana, Chong Wang, Drew Robert Magstadt, Darin M. Madson, John F. Patience, Eric Ryan Burrough

Bailey (Wilberts) Arruda

Diet has been implicated as a major factor impacting clinical disease expression of swine dysentery and Brachyspira hyodysenteriae colonization. However, the impact of diet on novel pathogenic strongly beta-hemolytic Brachyspira spp. including “B. hampsonii” has yet to be investigated. In recent years, distillers dried grains with solubles (DDGS), a source of insoluble dietary fiber, has been increasingly included in diets of swine. A randomized complete block experiment was used to examine the effect of increased dietary fiber through the feeding of DDGS on the incidence of Brachyspira-associated colitis in pigs. One hundred 4-week-old pigs were divided into five groups ...


The Influence Of Size Of Brood Cell Upon The Size And Variability Of The Honeybee (Apis Mellifera L .), Roy A. Grout 2017 Iowa State College

The Influence Of Size Of Brood Cell Upon The Size And Variability Of The Honeybee (Apis Mellifera L .), Roy A. Grout

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

1. Enlarged brood cells affect the size of the adult worker bee, and significantly larger worker bees are obtained through the use of enlarged cell foundation.

2. The average percentage increases of the linear measurements of the adult worker bees are almost proportional to the percentage increases of the diameters of the brood cells.

3. The increase in the size of the bee does not· quite keep pace with increases in cell size.

4. Size of brood cell apparently does not affect the variability of the adult worker bee, except possibly its dry weight.

5. The number of bees used ...
