The Snakes Of Iowa, J. E. Guthrie 2017 Iowa State College

The Snakes Of Iowa, J. E. Guthrie

Bulletin (Iowa Agricultural Experiment Station)

Altho the popular attitude toward snakes has always been hostile, most of them are harmless and they are often of great value to agriculture. The common practice of killing every snake that shows its head grows out of a lack of knowledge about these animals and their frequent usefulness. It is of economic importance to agriculture in Iowa and elsewhere to have available information as to the useful species of snakes, and ways of separating them from the harmful kinds.

Hemiscorpius Shahii Sp. N. From Iran (Scorpiones: Hemiscorpiidae), František Kovařík, Shahrokh Navidpour, Michael E. Soleglad

Euscorpius

Hemiscorpius shahii sp. n. from Iran, Hormozgan Province, is described and compared with other species of Hemiscorpius genus. The new species is characterized mainly by total length of 84 (female) to 110.7 (male) mm and unique trichobothrial pattern of pedipalp patella. The number of external trichobothria on patella is 17–18 (5 eb, 4 esb, 2–3 em, 3 est, 3 et); the number of ventral trichobothria on patella is 14–16. This distinguishes H. shahii sp. n. from all other species of genus Hemiscorpius, which have 3 or 10–12 ventral trichobothria on patella, one or two trichobothria ...

MANTER: Journal of Parasite Biodiversity

Based on original data obtained from fieldwork conducted from January 2008 to December 2015 and from previous records from published accounts, an updated checklist of helminth parasites of bats from Mexico and Central America is presented. The checklist has been organized in four ways, first as a helminth-host list in the state of Morelos, second as a helminth-host list with taxonomic and geographic distributional information, third as a bat-helminth list with references, and last, as a summary of the host-helminth association. A total of 105 records and 67 helminth taxa (26 trematodes, 4 cestodes, and 37 nematodes [33 adult and ...

Ectoparasitic Mites Of The Genus Gigantolaelaps (Acari: Mesostigmata: Laelapidae) Associated With Small Mammals Of The Genus Nephelomys (Rodentia: Sigmodontinae), Including Two New Species From Peru, Donald D. Gettinger, Scott Lyell Gardner 2017 University of Nebraska - Lincoln

Ectoparasitic Mites Of The Genus Gigantolaelaps (Acari: Mesostigmata: Laelapidae) Associated With Small Mammals Of The Genus Nephelomys (Rodentia: Sigmodontinae), Including Two New Species From Peru, Donald D. Gettinger, Scott Lyell Gardner

Scott Gardner Publications & Papers

An extensive survey of small mammals and ectoparasites along an altitudinal transect in the Manu Biodiversity Reserve in Peru found the sigmodontine rodent genus Nephelomys infested by mites of the genus Gigantolaelaps Fonseca, 1939. Two distinct species co-occurred exclusively in the pelage of Nephelomys keaysi, G. inca Fonseca and G. minima n. sp. Nephelomys levipes, which replaces N. keaysi at higher elevations, was infested exclusively with a single new species, G. nebulosa n. sp. In this paper, we formally describe these new mite species, and provide more information on the morphology of G. inca.


Evaluating The Social Behavior And Activity Patterns Of Clouded Leopards (Neofelis Nebulosa) At The Nashville Zoo: Research And Literature Review, Meghan Ryckeley 2017 Western Kentucky University

Evaluating The Social Behavior And Activity Patterns Of Clouded Leopards (Neofelis Nebulosa) At The Nashville Zoo: Research And Literature Review, Meghan Ryckeley

Honors College Capstone Experience/Thesis Projects

The behavior of the elusive clouded leopard (Neofelis nebulosa) is not well understood. In captivity, they are prone to exhibit stress-related behaviors and are often aggressive to conspecifics when paired. The present study built on past research by examining clouded leopards at the Nashville Zoo at Grassmere (NZG) to determine their activity patterns and temperament. Twelve leopards were exposed to familiar and unfamiliar objects and people, as well as their reflection in a mirror over nine trials. The males were often more reactive than the females, and the 5-year olds more reactive than their younger counterparts. The mirror image and ...


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.

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 ...


Autumn Foraging And Staging Ecology Of Eastern Population Sandhill Cranes (Antigone Canadensis Tabida), Everett E. Hanna 2017 The University of Western Ontario

Autumn Foraging And Staging Ecology Of Eastern Population Sandhill Cranes (Antigone Canadensis Tabida), Everett E. Hanna

Electronic Thesis and Dissertation Repository

Spatial and temporal variation in the density and distribution of waste agricultural grain (grain herein) during staging can affect the carrying capacity of habitats that support avian populations. Such variation in food resources can also have proximate effects on behavioural ecology (e.g., influence optimal behaviour). The Eastern Population of Greater Sandhill Cranes (Antigone canadensis tabida; EP herein) likely began to recolonize Ontario and its historic range starting in the early 1900s and now relies on agricultural grain during migration. Accordingly, ecologists possess little knowledge of how EP crane behavioural ecology may be affected by grain. Thus, my study focused ...


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.


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 ...

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 ...


African Penguins Follow The Gaze Direction Of Conspecifics, Christian Nawroth, Livio Favaro 2017 The Animal Studies Repository

African Penguins Follow The Gaze Direction Of Conspecifics, Christian Nawroth, Livio Favaro

Christian Nawroth, Ph.D.

Gaze following is widespread among animals. However, the corresponding ultimate
functions may vary substantially. Thus, it is important to study previously
understudied (or less studied) species to develop a better understanding of the
ecological contexts that foster certain cognitive traits. Penguins (Family
Spheniscidae), despite their wide interspecies ecological variation, have previously
not been considered for cross-species comparisons. Penguin behaviour and
communication have been investigated over the last decades, but less is known on
how groups are structured, social hierarchies are established, and coordination for
hunting and predator avoidance may occur. In this article, we investigated how
African penguins (Spheniscus demersus ...


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 ...
