Supernumerary Teeth In Pleistocene, Recent, And Hybrid Individuals Of The Spermophilus Richardsonii Complex (Sciuridae), H. Thomas Goodwin

Faculty Publications

A supernumerary distal upper molar, always expressed bilaterally, occurred in Pleistocene (one of 204) and Recent (five of 1,667) specimens of the Spermophilus richardsonii complex. Among Recent specimens with the abnormality, three of four with known provenance came from adjacent colonies with hybrids of S. richardsonii (Richardson's ground squirrel) and S. elegans (Wyoming ground squirrel). Elsewhere, the trait was rare in S. richardsonii (one of 947) and absent in S. elegans (out of 668). Affected individuals exhibited normal P3-M2, but two aberrant teeth distal to M2. Aberrant teeth exhibited a mosaic of features typical of M2, M3, and atypical of …

Seasonal Changes In Brown Fat And Pelage In Southern Short-Tailed Shrews, Elisa M. Dew, Keith A. Carson, Robert K. Rose

Biological Sciences Faculty Publications

We examined cellular changes in interscapular brown adipose tissue and pelage characteristics in Blarina carolinensis collected throughout the year in eastern Virginia. Cellular volume occupied by mitochondria and maximum mitochondrial size were significantly greater in the brown adipose tissue of winter shrews than in summer shrews. Lipid droplets occupied greater volume and were larger in shrews in summer than winter shrews. There were no seasonal differences in hair density; Type I and Type II guard hairs were significantly longer in winter than summer by a factor of 1.3. Woolly hairs were 1.2 times longer in winter than summer, a non-significant …

Cladistic Analysis Of 37 Mediterranean Bogidiellidae (Amphipoda), Including Bogidiella Arista, New Species, From Turkey, Stefan Koenemann, Ronald Vonk, Frederick R. Schram

Biological Sciences Faculty Publications

A new subterranean amphipod species, Bogidiella (Medigidiella) arista, found in the mesopsam mic ground waters of southern Anatolia, Turkey, is described, together with Bogidiella (Bogidiella) calicali Karaman, the latter being recorded for the first time in the eastern Mediterranean. A cladistic analysis of 37 Mediterranean species of the family Bogidiellidae is performed, using 4 species from the Canary Islands as an outgroup. Alternatively, 2 cladistic software packages, PAUP 3.1.1 and HENNIG86, are employed to calculate consensus trees of minimal length. The resulting trees show more or less identical robust clades, characterizing a central, a central-eastern, …

Wood Frog (Rana Sylvatica) Use Of Wildlife Ponds In Northcentral Arkansas, Michael E. Cartwright, Stanley E. Trauth, J. D. Wilhide

Journal of the Arkansas Academy of Science

Forty-one wildlife ponds were monitored between 1988 and 1992 for breeding use by wood frogs (Rana sylvatica). Data were collected on egg deposition and pond characteristics. Breeding activity and characteristics were similar to that reported in other portions of the range of the wood frog. We also monitored 15 newly-constructed ponds to determine chronological breeding patterns. Data collected for each site indicated a significant increase (P< 0.05) in the number of egg masses deposited in ponds as they age from 1-3 years during our study period. Increased chronological use of newly-constructed ponds may be due to localized population increase resulting from greater availability of breeding habitat

In-Stream Monitoring Of Sediments And Water In The Lower Ouachita River For Site Impact To Aquatic Biota, Jerry L. Farris, J. T. Knight, C. D. Milam, F. Buzen, J. F. Nix

Journal of the Arkansas Academy of Science

Reported reduced sportfish densities in the main channel of the Ouachita River prompted an investigation, beginning in 1990, into potential causes of ongoing impairment to aquatic biota. In-stream monitoring that incorporated toxicity testing of sediments and water was conducted to discern potential sources of contaminants that might be related to the suboptimal fishery populations. Organisms selected to evaluate chronic impairment included larval fish, clams, midges and water fleas. The fathead minnow {Pimephales promelas) and cladoceran (Ceriodaphnia dubid) were used to estimate patterns of toxicity associated with water from seven designated reaches and selected tributaries of the Ouachita River. Larval survival …

Telemetric Observations Of Foraging Ozark Big-Eared Bats In Arkansas, J. D. Wilhide, V. Rick Mcdaniel, Michael J. Harvey, Daniel R. White

Journal of the Arkansas Academy of Science

Ozark big-eared bat (Corynorhinus townsendii ingens) foraging activities were studied during 1995 in Marion County, Arkansas. Adult bats were equipped with radiotransmitters and tracked during June and July. Foraging activities were generally within 1 kilometer (km) of the roost cave. Male bats ranged farther than females with the exception of one female that flew 2.5 km into a different watershed. Male big-eared bats and northern long-eared bats (Myotis septentrionalis) were also found within the maternity colony.

Behaviour Of Gilbert's Potoroo (Potorous Gilbertii Gould) In Captivity, Kylie Dijon Burke

Theses : Honours

In late 1994, Gilbert's Potoroo was rediscovered almost 120 years after it was believed to have become extinct. It was found at Two Peoples Bay Nature Reserve, near Albany, Western Australia. Since then, it has become urgent that detailed studies of the potoroo's behaviour and ecology be undertaken, so as to increase the understanding of the needs of 'this critically endangered marsupial. Due to its critical status, increasing the number of animals is of paramount importance to the continued survival of this species. An understanding of the behavioural repertoire of the species will aid in its recovery and provide the …

A New Subspecies Of Meriones Tristrami Thomas, 1892 (Rodentia:Gerbillinae) From Kilis (Southeastern Turkey):Meriones Tristrami Kilisensis Subsp. N., Nuri Yi̇ği̇t, Ercüment Çolak

Turkish Journal of Zoology

In this study, seventeen specimens of Meriones tristrami from Kilis were compared with the specimens of Meriones tristrami bodenheimeri along with topotypes of Meriones tristrami lycaon close to those from Kilis. It was determined that the specimens from Kilis were distinguishable from M.t. lycaon by characters such as dorsal coloration, Tx100 / HB (ratio of tail length to head and body), zygomatic breadth, occipitonasal length, basal length, diastema length, occipital width, weight, baculum shape and fundamental number of chromosomes. Thus, the specimens of M. tristrami from Kilis were determined to be a new subspecies, Meriones tristrami kilisensis subps. n.

Contribution To The Taxonomy, Distribution And Karyology Of Martes Foina(Erxleben, 1777) (Mammalia: Carnivora) In Turkey, Nuri Yi̇ği̇t, Ercüment Çolak, Mustafa Sözen, Şakir Özkurt

Turkish Journal of Zoology

In this preliminary study, nine Stone Martens were recorded from different localities in Turkey. Their morphological characteristics were found to be consistent with previously published papers. However, the throat patches of Turkish Stone Martens show variations with respect to shape. In addition, it was determined that the morphologic and biometric characteristics of Turkish samples were consistent with those of M. f. syriaca. According to the karyological findings, the diploid number of chromosomes and the fundamental number were 38 and 76, respectively.

Metazoan Parasites And Other Symbionts Of Cetaceans In The Caribbean, Antonio A. Mignucci-Giannoni, Eric P. Hoberg, Doug Siegel-Causey, Ernest H. Williams Jr.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The parasite fauna in cetaceans from Puerto Rico, the Virgin Islands, and the larger Caribbean region is poorly known. We provide the first records for parasite biodiversity among a diverse assemblage of cetaceans from the Caribbean Sea. Internal and external parasites and commensals were collected from stranded whales and dolphins salvaged in Puerto Rico, the United States and British Virgin Islands, Jamaica, and Venezuela between 1989 and 1997. A total of 47 individuals of 16 species of whales and dolphins (15 odontocetes and one mysticete) were examined. Overall, parasites and commensals were found in 34 (72.3%) animals, representing 13 species …

Chondrocranial Anatomy And Skeletogenesis In Dendrobates Auratus, Rafael O. De Sá, Shannon Hill

Biology Faculty Publications

The larval chondrocranium and visceral skeleton of Dendrobates auratus ls described and compared with those of other dendrobatids. Four characters, i.e. lack of fusion between orbital cartilages and otic capsules, wide processus muscularis palatoquadrati, lack of processus pseudopterygoideus, and lack of processus anterolateralis hyalis, represent derived conditions for Dendrobates within Dendrobatidae. Cranial and postcranial ossification sequences are reported for D. auratus and Epipedobates tricolor. Skeletogenesis is earlier in E. tricolor, but the overall pattern of ossification is similar in the two species.

Turkish Journal of Zoology

In this study carbon-length regression was established for Arctodiaptomus bacilliferand length-weight relationships were established for Diaphanosoma lacustris, Keratella quadrata and Filinia longiseta, which are abundant in Lake Mogan. Great individual variation was determined in the carbon and nitrogen contents of Arctodiaptomus bacillifer, Furthermore, the length-weight regressions varied greatly for the, other zooplanktonic organisms according to sampling dates and, for some, to sampling points.

Influence Of Sediment On Heavy Metal Uptake By The Polychaete Arenicola Marina, Levent Bat

Turkish Journal of Zoology

In this study, the suitability of the polychaete Arenicola marina as a test organism using clean intertidal sediment contaminated with copper, zinc and cadmium was evaluated. Metal levels in casts were significantly lower than in unworked sediment indicating that the bioturbatory activity of lugworms might be significant in the distribution of the pollutants. This study showed that sediments contaminated with specific pollutants affected the uptake of these pollutants by Arenicola in a predictable and dose–dependant way and gave further justification for the use of this species in sediment toxicity tests.

Ultrastructural Study On The Ovarian Wall And The Oviduct Of The Asellus Aquaticus (Crustacea: Isopoda), B. Melike Erkan

Turkish Journal of Zoology

In this study the ovarium, ovarian wall and oviduct of Asellus aquaticus ( A. aquaticus) (Crustacea: Isopoda) were investigated by stereomicroscopy, phase contrast microscopy and light microscopy. Long, tube-shaped, separate ovaries of A. aquaticus are located dorsolateral to the gut. The germinal zone is confined to the ventral region of the ovary as a thin band. The ovarian wall is composed of a few fibrous layers. The oviduct is located in the anterior one-third of the ovary, not in the central part. The sheath of the oviduct was found to possess some muscle cells, a feature first noted in this …

A Comparison Of Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison

Masters Theses

I compared rates of predation between real and artificial nests of grassland birds in order to test the impact of nest type, nest position, and egg size on predation rates. I distributed wicker avicultural baskets and realistic grass nests baited with a clay egg and either northern bobwhite (Colinus virginianus) or house sparrow (Passer domesticus) eggs in four Conservation Reserve Program (CRP) grasslands in east-central Illinois. Nest success averaged 86.5% for 12 days of exposure for artificial nests. For real nests, nest success was markedly lower; averaging 39% over the entire nesting cycle and 59% during approximately 12 days of …

Heartworm And Lungworms In Illinois' Canids And Their Possible Effect On Coyote Condition And Reproduction, David G. Gregory

Masters Theses

This study focuses on the prevalence of heartworm and lungworms in Illinois' canid species, and the effect that they may have on condition (body weight, kidney fat, marrow fat) and reproduction (placental scars) on coyote populations. A total of 1,150 coyotes (Canis latrans), 2,269 domestic dogs, 47 red foxes (Vulpes vulpes), and 2 gray foxes (Urocyon cinereoargenteus) were examined. Prevalence of heartworms (Dirofilaria immitis) averaged 17.8% in coyotes, 3.0% in domestic dogs, 2.0% in red foxes, and 0% in gray foxes. Domestic dogs not receiving any type of prophylactic treatment had a higher prevalence (12.5%) of heartworms than dogs on …

A Probable Nesting Of Clark's Nutcracker (Nucifraga Columbiana) In Nebraska,, Wayne Mollhoff

Nebraska Bird Review

This report provides details on the probable nesting of Clark's Nutcracker (Nucifraga columbiana) in Morrill, Scotts Bluff Co., Nebraska, in 1997. It also corrects an erroneous report of nesting in the Pine Ridge area of Nebraska (Silcock & Jorgensen 1997b).

A single Clark's Nutcracker was first noted corning to a suet feeder at the home of Ms. Edna C. Thomas in Morrill 8-9 Jan 1997. It came to the feeder at least weekly and was often seen daily. A second Clark's Nutcracker appeared during the second week of Feb. Initially, the bird already present was antagonistic towards it …

Black-Throated Sparrow Banded In Omaha, Nebraska, Ruth C. Green

Nebraska Bird Review

On 20 December 1997, I banded a Black-throated Sparrow in the vicinity of 43rd and J Streets in South Omaha, Nebraska. The band number on this bird is 2120/83856. It was an AHY-Male and, according to the description given by James D. Rising in his book, A Guide to the Identification and Natural History of the Sparrows of the United States and Canada, it was of the subspecies Amphispiza b. bilineata. This is the smallest of the three races found in the united States and it is indigenous to central Texas. Besides the smaller size, the identifying field …

Fall Field Report, August-November 1997, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

Notable this Fall was very heavy coverage of the Panhandle during Sep-Oct, which yielded several outstanding records (all, of course, pending NOURC approval). Incredible were first Panhandle records of Golden-winged, Chestnut-sided, Bay-breasted, and Prothonotary Warblers, 3rd record of Northern Waterthrush, and 4th record of Blackburnian Warbler. Philadelphia Vireo was found in the Panhandle for the 3rd time. Important also were 3 records of Hammond's Flycatcher, the 3rd-6th for the state, and likely a regular migrant, and 5 of Cassin's vireo, previously known only by 2 specimens. Finally, from the Panhandle, 4 reports of Blue-Gray Gnatcatcher may be changing the status …

Nebraska Bird Review

EDITOR'S COMMENTS

This issue is the last of my six-year term as Editor of The Nebraska Bird Review. It has been a challenging and stimulating experience, and I have learned much about bird lore and publishing methods. My workload was lightened considerably when Ross Silcock took on the seasonal field reports in 1994, assisted initially by Richard C. Rosche and recently by Joel G. Jorgensen. Dr. R. G. (Rusty) Cortelyou volunteered to compile the index for each volume during my term. This is a time-consuming and detailed project, and I sincerely appreciate his contribution.

I am very pleased that Dr. …
