First Confirmed Records Of Dusky Flycatcher For Nebraska, Stephen J. Dinsmore, W. Ross Silcock

Nebraska Bird Review

Prior to the fall of 2000, there were no accepted records of Dusky Flycatcher for Nebraska. With the exception of a single sight record by Silcock (17 May 1992) judged "Hypothetical" by the Nebraska Ornithologists' Union Records Committee, this species had been unreported in Nebraska. Dusky Flycatchers breed locally in the Black Hills of South Dakota (Peterson 1990) and were presumed to occur in western Nebraska. Here, we report the capture of three Dusky Flycatchers in Kimball County and three additional sight records from western Nebraska.

On 31 August 2000, we were mist netting below the dam of Oliver Reservoir …

The 2000-2001 Nebraska Christmas Bird Count, Stephen J. Dinsmore

Nebraska Bird Review

The 2000-2001 Christmas Bird Count (CBC) period included nine counts in Nebraska, down one from last year. New this year was the resurrected Crawford count while Kearney and Dakota-Dix were missing (Table 1). These counts reported a total of 117 species and nearly 138,000 individuals, which is not bad for such a cold count period. Counts were scattered statewide, but most effort was in the eastern half of the state where most of the birders are. The top count again this year was Lake McConaughy with 93 species. Other excellent totals included 71 at Harlan County and 65 at Branched …

Bats Of The West Indian Island Of Dominica: Natural History, Areography, And Trophic Structure, Hugh H. Genoways, Carleton J. Phillips, Robert M. Timm, Duane A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

Because the islands in the Caribbean long have interested students of mammals and zoogeography, considerable information has been published concerning the biology of the Antillean mammalian fauna in the past three decades (Jones and Schwartz, 1967; Schwartz and Jones, 1967; Koopman, 1968, 1989; Jones and Phillips, 1970, 1976; Varona, 1974; Baker and Genoways, 1978; Baker et al., 1978; Swanepoel and Genoways, 1978; Jones and Baker, 1979; Silva Taboada, 1979; Baker et al., 1984; Eshelman and Morgan, 1985; Buden, 1986; Griffiths and Klingener, 1988; Jones, 1989; Masson et al., 1990; Pederson et al., 1996; Genoways et al., 1998).

Internesting Movements Of Loggerhead (Caretta Caretta) Sea Turtles In Virginia, Usa, Katherine L. Mansfield, John A. Musick, Soraya M. Bartol

Reports

Virginia is the northern most nesting region regularly utilized by loggerhead sea turtles (Caretta caretta) along the eastern coast of the United States. Along the southern shoreline of Virginia, between two and ten nests have been recorded annually since 1989 within Back Bay National Wildlife Refuge and False Cape State Park. Since 1992, the Virginia Institute of Marine Science (VIMS) has attached eight satellite transmitters to nesting loggerhead sea turtles in order to monitor their interesting movements and falVwinter migrations. VIMS has tracked the same nesting loggerhead three separate times during the 1993, 1995 and 1997 nesting seasons. This turtle …

Rare, Threatened And Endangered Plants And Animals Of Oregon (2001), James S. Kagan, Sue Vrilakas, Eleanor P. Gaines, Cliff Alton, Ken Popper, Mark A. Stern, Eric Scheuering, John A. Christy, Mary Finnerty, Jon Hak, Anthony A. Tovar, Michael Murray, Claudine Tobalske, Oregon Natural Heritage Program

Institute for Natural Resources Publications

Extinction is a natural process. Today, however, plant and animal species are disappearing world-wide at an accelerated pace. Based on current trends, half of the species on earth will be extinct within the next 100 years. The major cause of this phenomenon is large-scale destruction of native habitats, which has increased since European settlement began in the mid 1800's - in Oregon and throughout the New World.

Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend …

Peripheral Blood Leukocyte Response And Macrophage Function During Eimeria Adenoeides Infection In Turkey Poults, Amanda D. Drake, Sarah E. Heuer, Timothy G. Kimball, Timothy O. Peters, H. David Chapman, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Intestinal coccidiosis, caused by various species of Eimeria, is an economically important disease of chickens and turkeys. The peripheral blood leukocyte response and macrophage functions during a coccidial infection in turkeys have not been defined. To examine these aspects of innate immunity during primary Eimeria infection in turkeys, 4-week-old poults were orally inoculated with either 50,000 E. adenoeides oocyst (24 infected poults) or water (24 control poults). To monitor the concentrations and proportions of white blood cells (WBC) throughout the course of infection, heparinized blood was collected from 12 infected and 12 control poults prior to inoculation (day 0), and …

The Possible Enzymatic Differences Between Cattle And Sheep In Their Response To Ergot Alkaloids, Susan M. Cannon, Charles F. Rosenkrans, Ali Moubarak

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Ergotamine is an ergot alkaloid associated with fescue toxicosis of livestock who have grazed endophyte-infected fescue. High performance liquid chromatography (HPLC) was used to detect individual or species-specific differences in the metabolism of ergotamine by liver cytochrome P450 of sheep and cattle. Livers were collected from four steers and two sheep. The diet of the steers used in this study consisted of two being fed a grain diet, one steer grazing endophyte-infected fescue, and the final steer grazing endophyte-free fescue. The two lambs were both fed a grain diet. Livers were prepared and examined for the disappearance of ergotamine and …

A Study On The Feeding Biology Of Laudakia (=Agama) Stellio (L. 1758) (Lacertilia: Agamidae) Populations In The Antalya Region, Serdar Düşen, Mehmet Öz

Turkish Journal of Zoology

The feeding biology of Laudakia (=Agama) stellio (L. 1758) was studied using 91 specimens collected from the Antalya region over two consecutive years (1995 and 1996). A total of 1224 prey items were identifed and their frequency of occurrence and percent of diet were tabulated. The majority of the diet consisted of the class Insecta (99.18%), and within this class, Hymenoptera (72.21%) was the major order represented, primarily by the families Formicidae (49.83%) and Apidae (16.74%). In addition to insects, L. stellio feeds on plant material, insect larvae and eggs, and even snails, showing opportunist feeding behavior.

Effects Of Hydroperiod On Metamorphosis In Rana Sphenocephala, Travis J. Ryan, Christopher T. Winne

Scholarship and Professional Work - LAS

Hydroperiod, the time a temporary pond holds water, is an important factor influencing recruitment in amphibian populations and structuring amphibian communities. We conducted an experiment to test the effect of hydroperiod on metamorphic traits of the southern leopard frog (Rana sphenocephala), a common amphibian in the southeastern United States. We reared larval R. sphenocephala in artificial ponds at a density of 32 larvae per tank (initial volume = approximately 650 liter). We dried the tanks according to natural patterns, using three different hydroperiods (60, 75 and 90 d). Experimental hydroperiods had a significant effect on the number of …

Do Naked Goby (Gobiosoma Bosci) Larvae Exhibit Periodic Vertical Movements In Order To Facilitate Upriver Migration In The Hudson River Estuary?, Megan C. Fencil, Eric T. Schultz

EEB Articles

Estuaries provide high quality nursery habitat for larval fishes due to high productivity, predator protection, and warm temperatures. Previous studies suggest that larval naked gobies (Gobiosoma bosci) are capable of upriver migration and estuarine retention despite net seaward flow. Gobiosoma bosci larvae were collected at a fixed site in the Hudson River estuary in late July of 1998 from 4 discrete depths to provide a time-series of depth-stratified abundance during both a spring and a neap tide. Larvae were concentrated at depth, indicating that depth preference behavior is present and will likely contribute to up-river transport. Harmonic regression …

Reward Frequency: Effects On Flower Choices Made By Different Honeybee Races In Turkey, İbrahi̇m Çakmak, Harrington Wells

Turkish Journal of Zoology

We compared the European honeybee races Apis mellifera armeniaca, A.m. caucasica, A.m. cypria, and A.m. syriaca. These subspecies are endemic to very different habitats. Additionally, they are exposed to very different levels of predation. A.m. caucasica exists where honeybee predators typically are rare, while the remaining subspecies have ranges that coincide with areas where honeybee predators are abundant. Foraging decisions of workers visiting artificial flower patches containing blue, white, and yellow flowers were recorded. We tested whether foragers responded to differences in rewarding flower frequency among flower color morphs. Division of labor occurred among foragers of each race; some bees …

Effect Of Water Temperature On Growth Of Hatchery Reared Black Sea Turbot, Scophthalmus Maximus (Linnaeus, 1758), Temel Şahi̇n

Turkish Journal of Zoology

A rearing experiment was carried out to examine the effect of water temperature on the growth of the Black Sea turbot, Scophthalmus maximus, at ambient temperature (mean 15.2±0.6°C), 18, 20, 22 and 24°C with fish of 34.4±9.9 g initial body weight. The experiment lasted 30 days and the fish were fed to satiation three times a day with a commercial pelleted diet. Survival rates starting with the control group were 100, 83.4, 68.4, 3.4, and 1.7%, respectively. Although the mean weights of the groups were very similar at the beginning of the experiment, they had become markedly varied by the …

Ultrastructural Observations On The Development Of Some Actinosporean Types Within Their Oligochaete Hosts, Ahmet Özer, Rodney Wootten

Turkish Journal of Zoology

Synactinomyxon type 1, aurantiactinomyxon type 3, echinactinomyxon type 5 and raabeia type 4 were studied at the TEM level in order to determine the developmental stages within their oligochaete hosts. All the actinosporean types studied had uninucleate cells as the earliest stage of development. The formation of a subsequent binucleate cell stage was either due to the division of the nucleus in a uninucleate cell or the plasmogamy of two uninucleate cells. The earliest pansporocyst formation seen was two outer somatic cells surrounding two inner generative \alpha and \beta cells in all the actinosporean types studied. However, the formation of …

A Study On Endocrine Cells In The Midgut Of Agrotis Segetum (Denn.And Schiff.) (Lepidoptera:Noctuidae), Nursel Gül, Hakki Sayar, Nesri̇n Özsoy, Cevat Ayvali

Turkish Journal of Zoology

The structure of midgut endocrine cells of Agrotis segetum larvae was examined by light and electron microscopy. It was observed that the endocrine cells were located on the basal lamina and among the columnar epithelial cells of the midgut. The cells were morphologically determined as columnar or coniform. The cytoplasm of endocrine cells was observed to contain rough endoplasmic reticulum, mitochondria, developed Golgi complex, vesicles and numerous small secretory granules. It was also observed that the secretory granules were often located in the basal region of the endocrine cells.

Histological Study Of The Organogenesis Of The Digestive System And Swim Bladder Of The Chalcalburnus Tarichi Pallas, 1811 (Cyprinidae), Güler Ünal, Osman Çeti̇nkaya, Ertuğrul Kankaya, Mahmut Elp

Turkish Journal of Zoology

The histological development of the digestive system and swim bladder of Chalcalburnus tarichi larvae and their histology in adults were studied under light microscopy. After hatching, the digestive tract is a simple undifferentiated tube. Exogenous feeding started on the 6th day. The yolk sac was absorbed completely on the 9th day. The goblet cells appeared first in the bucco-pharyngeal cavity and oesophagus on the 4th day, in the anterior on the 9th day and in the posterior intestine on the 5th day. The digestive tract was differentiated as the buccal cavity, pharynx, oesophagus post-eosophageal swelling and intestine on the 5th …

The Structure Of Baculum In Myotis Myotis And Myotis Blythi (Chiroptera: Vespertilionidae) From Turkey, İrfan Albayrak, Nursel Aşan

Turkish Journal of Zoology

A comparison was made of the shape and size of the bacula of 32 Myotis myotis (Borkhausen, 1797) and 26 Myotis blythi (Tomes, 1857) collected from Turkey. It was determined that baculum size does not distinguish the two species but baculum shape distinguishes them.

New Rumen Ciliates From Turkish Domestic Cattle (Bos Taurus L.): 3. Entodinium Oektemae N. Sp. And Entodinium Imaii N. Sp. (Entodiniidae, Entodiniomorphida), Bayram Göçmen, Murat Tosunoğlu, Beri̇a Falakali Mutaf

Turkish Journal of Zoology

Certain entodiniid ciliates, somewhat different from those previously described (1), were observed the during examination of the rumen contents of 30 adult domestic cattle (Bos taurus L.) in the vicinity of Izmir. We propose that these new forms should be taxonomically named Entodinium oektemae n. sp. and Entodinium imaii n. sp. The frequencies Entodinium oektemae n. sp. and Entodinium imaii n. sp. were 6.67% 16.67% respectively. The main characteristics of these two species are described in detail and discussed in comparison with those of the previously reported ones.
