Nebraska’S First Curlew Sandpiper (Calidris Ferruginea), Joel G. Jorgensen, W. Ross Silcock Mar 1998

Nebraska’S First Curlew Sandpiper (Calidris Ferruginea), Joel G. Jorgensen, W. Ross Silcock

Nebraska Bird Review

During a birding trip on 19 July 1997, we stopped at Funk WPA, Phelps County. While viewing from the north-south road that runs through the marsh at the east end of the marsh, we caught glimpses of a large group of shorebirds behind cattails in an area on the south side of the main marsh and about a third of a mile west of the road. We eventually decided to walk out and get a closer look at the shorebirds. Once we were close enough we were able to see that there were approximately 250 shorebirds. We began sifting through …

Bald Eagle Nest Monitoring - Nebraska, 1997 Summary Report, John J. Dinan Mar 1998

Bald Eagle Nest Monitoring - Nebraska, 1997 Summary Report, John J. Dinan

Nebraska Bird Review

In 1997, 38 Bald Eagle (Haliaeetus leucocephalus) nests in 22 counties were surveyed for breeding activity. Eagles occupied territories at 10 of these sites. These same 10 territories were occupied in 1996. Two separate, mid-July sightings of Bald Eagles along the Niobrara River, one of an adult and three juveniles in Knox County and one of an adult and a juvenile in Holt County, suggests the presence of additional nesting territories. All nest attempts in 1997 were successful, producing a total of 16 fledged young. The Lake Alice nest on the North Platte National Wildlife Refuge fell during …

Winter Field Report, Dec 1997 To Feb 1998, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

As one observer (DH) noted, this was a "weird" winter. January and February were more like March, producing winter reports of species with few such previous reports; the species involved come from all parts of the taxonomic list, from loons to icterids. Almost certainly, a first (in recorded history) was a slam of all the Nebraska grebe species in January, even Red-necked and Clark's! Also in January, a Pacific Loon was reported. As shown in the species' accounts below, the list of rare midwinter species is long.

Another significant, related finding involved early-arriving spring migrants, also a long list. In …


Mystery Duck At Sinninger Waterfowl Production Area, York County, Joel G. Jorgensen Mar 1998

Mystery Duck At Sinninger Waterfowl Production Area, York County, Joel G. Jorgensen

Nebraska Bird Review

On the evening of 8 May 1997, I was scanning the shorebirds and ducks at the cattleyard basin of Sinninger WPA, York County. Most of the 300 or so puddle ducks were Bluewinged Teals (Anas discors), but also present were Green-winged Teal (A. crecca), American Wigeon (A. americana), Gadwall (A. strepera), Northern Shoveler (A. clypeata), and a Cinnamon Teal (A. cyanoptera). I eventually noticed a male duck in breeding plumage that superficially resembled a Baikal Teal (A. formosa). All descriptive discussion that follows is of male …


Natural History Of The Southern Short-Tailed Shrew, Blarina Carolinensis, Hugh H. Genoways, Jerry R. Choate Feb 1998

Natural History Of The Southern Short-Tailed Shrew, Blarina Carolinensis, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

The southern short-tailed shrew, Blarina carolinensis, inhabits a broad range of ecological situations in the southeastern United States and, in many areas, is among the two or three most abundant species of small mammals. Nevertheless, its natural history is poorly known and much of what researchers assumed was fairly well understood about this species actually resulted from work on another species (Blarina brevicauda) and may not be correct in all instances. This problem resulted when modem systematic methods revealed that the wide-ranging and well-studied species known at that time as Blarina brevicauda actually consisted of three species …


Randomly Amplified Polymorphic Dna Analysis (Rapd) Of Artemisia Subgenus Tridentatae Species And Hybrids, E. Durant Mcarthur, Joann Mudge, Renée Van Buren, W. Ralph Andersen, Stewart C. Sanderson, David G. Babbel Jan 1998

Randomly Amplified Polymorphic Dna Analysis (Rapd) Of Artemisia Subgenus Tridentatae Species And Hybrids, E. Durant Mcarthur, Joann Mudge, Renée Van Buren, W. Ralph Andersen, Stewart C. Sanderson, David G. Babbel

Great Basin Naturalist

Species of Artemisia (subgenus Tridentatae) dominate much of western North America. The genetic variation that allows this broad ecological adaptation is facilitated by hybridization and polyploidization. Three separate studies were performed in this group using randomly amplified polymorphic DNA (RAPD). Fifty-seven 10-mer primers generated nearly 400 markers from genomic DNA obtained from leaf tissue. These studies were (1) a measure of the variability of plants within and between populations and between subspecies using 5 A. tridentata ssp. wyomingensis populations, 2 A. cana ssp. cana populations, and 1 A. cana ssp. viscidula population; (2) an examination of the hypothesis that …


The Evolution Of Primate Malaria Parasites Based On The Gene Encoding Cytochrome B From The Linear Mitochondrial Genome, Ananias A. Escalante, Denise E. Freeland, William E. Collins, Altaf A. Lal Jan 1998

The Evolution Of Primate Malaria Parasites Based On The Gene Encoding Cytochrome B From The Linear Mitochondrial Genome, Ananias A. Escalante, Denise E. Freeland, William E. Collins, Altaf A. Lal

Harold W. Manter Laboratory of Parasitology: Library Materials

We report a phylogenetic analysis of primate malaria parasites based on the gene encoding the cytochrome b protein from the mitochondrial genome. We have studied 17 species of Plasmodium, including 14 parasitic in primates. In our analysis, four species were used for rooting the Plasmodium phylogenetic tree: two from closely related genera (Hepatocystis sp. and Haemoproteus columbae) and two other Apicomplexa (Toxoplasma gondii and Theileria parva). We found that primate malaria parasites form a monophyletic group, with the only exception being the Plasmodium falciparum–Plasmodium reichenowi lineage. Phylogenetic analyses that include two species …


Management Of Red Squirrel Feeding Damage To Lodgepole Pine By Stand Density Manipulation And Diversionary Food, Thomas P. Sullivan Jan 1998

Management Of Red Squirrel Feeding Damage To Lodgepole Pine By Stand Density Manipulation And Diversionary Food, Thomas P. Sullivan

Vertebrate Pest Conference Proceedings: 18th (1998)

The red squirrel (Tamiasciurus hudsonicus) feeds on the vascular tissues of sapling lodgepole pine (Pinus contorta) during spring periods in forests of interior British Columbia and Alberta, Canada. This damage may lead to mortality and reduced growth of crop trees in managed stands. Manipulation of stand density by pre-commercial thinning to densities < 1,000 stems/ha is an effective method to lower squirrel populations and feeding damage. Lowering stand density enhances the growth of crop trees, and understory herbs and shrubs as wildlife habitat, while protecting trees from squirrel feeding. This approach has been successful in several forest ecological zones. An alternative management tool is provision of diversionary food (sunflower seed) for those stands susceptible to feeding damage, and where stand thinning has already been completed. Diversionary food can be applied aerially and is very cost effective for protecting managed stands. These techniques may be used to maintain or even enhance species diversity of small mammal communities in those forest stands requiring protection.

Notes On The Natural History Of Lasiurus Borealis In Arkansas, David A. Saugey, Robin L. Vaughn, Betty G. Crump, Gary A. Heidt

Journal of the Arkansas Academy of Science

Since June 1982 we have studied various aspects of red bat ecology in Arkansas with emphasis on field work in the Ouachita Mountains and examination of specimens submitted to the Arkansas Department of Health Rabies Laboratory (ADHRL).This study reports on continued field work in the Ouachita Mountains using radiotelemetry and updates information regarding red bats submitted to the ADHRL through December 1996. In addition, we revisited a cave previously reported to contain a large number of red bat skull and skeletal remains. We also report remains from another cave system in northcentral Arkansas. These investigations have yielded additional information on …

Phorbol Ester Activation Of An Nhe-Like Electroneutral Na+ /H+ Antiporter In Isolated E-Cells Of Lobster (Homarus Americanus) Hepatopancreas, Jeff Duerr, Gregory A. Ahearn Jan 1998

Phorbol Ester Activation Of An Nhe-Like Electroneutral Na+ /H+ Antiporter In Isolated E-Cells Of Lobster (Homarus Americanus) Hepatopancreas, Jeff Duerr, Gregory A. Ahearn

Faculty Publications - Department of Biological & Molecular Science

The basolateral membrane of Atlantic lobster (Homarus americanus) epithelium possesses an electroneutral Na+ /H+ antiporter that functionally resembles members of the vertebrate NHE family. Regulatory mechanisms of this antiporter in purified hepatopancreatic E-cell suspensions, produced with a centrifugal elutriation technique, were investigated. Suspensions routinely consisted of greater than 95% E-cells displaying greater than 90% viability. Intracellular pH (pHi) was monitored by loading cells with the fluorescent dye 2´,7´-bis(carboxyethyl)-5,6- carboxyfluorescein (BCECF), and placing suspensions in a spectrofluorometer. Recovery from induced acid-loading was mediated by a Na+ -dependent, dimethylamiloride-sensitive proton efflux. Antiport activation was a sigmoidal function of pHi at values below …

In the present study, the zooplanktonic fauna of the Kunduzlar and Çatören dam lakes (Kirka basin-Eskişehir) was investigated during August 1994-June 1995. Eight species of Rotifera, five species of Cladocera and two species of Copepoda were identified in both dam lakes. In addition, the mean zooplankton abundance (ind. m -3 ) and physical and chemical parameters of dam lakes were given.


Intraspecific Heterochrony And Life History Evolution: Decoupling Somatic And Sexual Development In A Facultatively Paedomorphic Salamander, Travis J. Ryan, Raymond D. Semlitsch Jan 1998

Intraspecific Heterochrony And Life History Evolution: Decoupling Somatic And Sexual Development In A Facultatively Paedomorphic Salamander, Travis J. Ryan, Raymond D. Semlitsch

Scholarship and Professional Work - LAS

Morphological features such as size and shape are the most common focus in studies of heterochronic change. Frequently, these easily observed and measured features are treated as a major target of selection, potentially ignoring traits more closely related to fitness. We question the primacy of morphological data in studies of heterochrony, and instead suggest that principal sources of fitness, such as life history characteristics, are not only the chief targets of selection, but changes in them may necessitate changes in other (subordinate) elements of the organism. We use an experimental approach to investigate the timing of metamorphosis and maturation in …


Highland Pond Utilization By Bats In The Ozark National Forest, Arkansas, J. D. Wilhide, Michael J. Harvey, V. Rick Mcdaniel, Vernon E. Hoffman Jan 1998

Highland Pond Utilization By Bats In The Ozark National Forest, Arkansas, J. D. Wilhide, Michael J. Harvey, V. Rick Mcdaniel, Vernon E. Hoffman

Journal of the Arkansas Academy of Science

During May through August 1996, wildlife ponds (man-made and/or naturally occurring) and road ruts on the Sylamore Ranger District, Ozark National Forest, Arkansas, were mist netted to determine extent of utilization by bats. Thirty-nine ponds and road ruts were netted one or more times during 53 nights. These water sources were originally constructed to support wildlife species such as deer, turkey, etc.. This study demonstrates that taxonomically and numerically diverse bat populations use these water sources. Seven hundred and seventy bats of nine species, including two endangered species, were netted. Bats were identified, and sex, reproductive status, forearm length, and …


Quantifying Community Separation And Increase In Number Of Avian Species With Corresponding Increase In Habitat Complexity, An African Example, Douglas A. James Jan 1998

Quantifying Community Separation And Increase In Number Of Avian Species With Corresponding Increase In Habitat Complexity, An African Example, Douglas A. James

Journal of the Arkansas Academy of Science

The relationship between increase in faunal diversity and corresponding increase in habitat complexity was quantified using shrubland bird communities in western Africa. Vegetational characteristics were measured in circular plots around bird positions. Bird species were then arranged from grassy open habitats to dense shrubland and found to be separated into three distinct communities when subjected to Duncan's multiple range procedure in conjunction with discriminant functions analysis. Random samples classified with respect to bird species showed there were few species in the more abundant open habitats and a disproportionate number of species were packed into the less common but complex shrubby …


Hibernation And Body Weight In Dormice, Glis Glis Orientalis(Nehring, 1903) (Rodentia: Gliridae), Maintained Underuncontrolled Conditions, Ercüment Çolak, Nuri Yi̇ği̇t, Mustafa Sözen, Şakir Özkurt Jan 1998

Hibernation And Body Weight In Dormice, Glis Glis Orientalis(Nehring, 1903) (Rodentia: Gliridae), Maintained Underuncontrolled Conditions, Ercüment Çolak, Nuri Yi̇ği̇t, Mustafa Sözen, Şakir Özkurt

Turkish Journal of Zoology

Hibernation pattern and changes in the body weight of juvenile and adult dormice, Glis glis orientalis, kept in uncontrolled conditions were investigated. It was determined that G.g.orientalis entered hibernation on October 28 when its body weight was 180 g and the ambient temperature was below 18 ºC, which seems to be the critical temperature for entering hibernation. Although body weight has an important role in entering hibernation at the beginning of the hibernation season, dormice hibernated as the hibernation season progressed regardless of their body weight. Adult dormice arose from hibernation during the period of May 13 to June 6. …

Early Development Of Barbel ( Barbus Barbus L.) Larvae, Metin Çalta Jan 1998

Early Development Of Barbel ( Barbus Barbus L.) Larvae, Metin Çalta

Turkish Journal of Zoology

In this study, the early development of barbel ( Barbus barbus L.) larvae has been determined by measuring their wet weight, dry weight, whole body mineral content (Ca, Mg, Na and K), skeletal development and gill development. It has been observed that wet weight, whole body mineral contents, the number of lamellae per filament of gill and the number of calcified vertebrae of larvae during early development stage increased by age, whereas dry weight decreased. The increase of whole body magnesium content has been very low compared with that of other minerals. In addition, a possitive relationship between whole body …

Physiological Energetics Of Buccinum Undatuml. (Gastropoda) Off Douglas,Isle Of Man (The Irish Sea), Ahmet E. Kideyş Jan 1998

Physiological Energetics Of Buccinum Undatuml. (Gastropoda) Off Douglas,Isle Of Man (The Irish Sea), Ahmet E. Kideyş

Turkish Journal of Zoology

Physiological energetics of the common whelk ( Buccinum undatum) were studied in a population off Douglas, Isle of Man and an energy budget was constructed for the period February 1989 to January 1990. The components of the energy budget (in kJ m -2 year -1 ) for the population can be summarized thus: consumption (C)=753; growth production (P g )=34; reproductive production (P r )=4; mucus production=218; respiration (R)=96; ammonia excretion (U)=8; and faecal production (F)=393. Assimilation efficiency was 47.7%. P/B (annual production/biomass) was calculated as 1.40 representing an intermediate life span for this species.
