This behavior lasted 42 sec. This behavior was repeated 23 out of 24 trials conducted during the next 24 days. The duration of swallowing wes 9-62 sec (avg 35.8, N = …

The Bats Of Fountain Cavern, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

First paragraph:

During May 1988, two species of bats--Brachyphylla cavernarum (Antillean cave bat) and Natalus stramineus (funnel-eared bat)--were captured at the opening of Fountain Cavern. Only Brachyphylla cavernarum was captured inside of the cave. The weather was extremely wet during our visit to Anguilla so our work in Fountain Cavern was limited by hazardous conditions. Nevertheless, we did make a thorough survey of the bats inside the cave. There is only one other species on Anguilla--Monophyllus redmani (Antillean long-tongued bat)--that might be expected to utilize Fountain Cavern as a roosting site.

Includes the author's recommendations about conservation for …

Caribbean Island Zoogeography: A New Approach Using Mitochondrial Dna To Study Neotropical Bats, Carleton J. Phillips, Dorothy E. Pumo, Hugh H. Genoways, Phillip E. Ray

University of Nebraska State Museum: Mammalogy Papers

Genetic analysis of animal mitochondrial DNA is a new and valuable addition to the battery of techniques available to zoogeographers. This paper describes characteristics of mitochondrial DNA (mtDNA) that make it applicable for the study of island zoogeography.

Some traditional zoogeographic questions are examined using mtDNA from the Neotropical fruit bat, Artibeus jamaicensis. The specific questions are: 1) To what extent are island populations isolated (that is, does interbreeding occur between the insular subspecies)? 2) Can a single founding female account for the mitochondrial genomes on specific islands in the Antilles? 3) Is there a correlation between the genomic …

Effects Of Methylxanthines On Newborn Rat Respiration, Craig Gatto

Masters Theses

Methylxanthines (MX), such as theophylline, are commonly used in the treatment of recurrent apnea due to their stimulant effects on the respiratory center. Structure-activity studies have demonstrated that substitution of alkyl groups on the 3-position of the xanthine nucleus results in increased bronchodilator potency, while substitution on the 1-position is important for adenosine antagonism and CNS stimulation. Three different alkylxanthines were studied to determine the structural requirements for respiratory stimulation. Respiratory rates and volumes were determined in 4- to 7-day-old rats using a volume displacement body plethysmograph. Measurements were made before and at 5 minute intervals after subcutaneous (s.c.) injection …

Coccidia (Apicomplexa: Eimeriidae) From The Subterranean Rodent Ctenomys Opimus Wagner (Ctenomyidae) From Bolivia, South America, Christine R. Lambert, Scott Lyell Gardner, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Of 35 tuco-tucos (Ctenomys opimus) collected in Bolivia, South America, 31 (88%) had eimerian oocysts in their feces at the time they were examined. Eighteen (58%) of the 31 infected animals were concurrently infected with 2 or 3 eimerian species. Four species of Eimeria were recovered and are described as new species based on the characteristics of sporulated oocysts. Oocysts of E. granifera n. sp. were ellipsoidal, 21.1 x 17.2 (15-26 x 11-20), μm with sporocysts ovoidal, 11.3 x 7.1 (8-14 x 5-9), μm.

Cestodes Of The Genus Hymenolepis Weinland, 1858 Sensu Stricto From Pocket Gophers Geomys And Thomomys Spp. (Rodentia: Geomyidae) In Colorado And Oregon, With A Discriminant Analysis Of Four Species Of Hymenolepis, Scott Lyell Gardner, Gerald D. Schmidt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes found to represent previously undescribed members of the genus Hymenolepis s. str. (Yamaguti, 1959) were recovered from pocket gophers, Geomys bursarius (Shaw), in northeastern Colorado. Hymenolepis weldensis n. sp. and H. geomydis n. sp., not occurring together in any individual host, were found in 3 and 8%, respectively, of pocket gophers examined for helminths. The life cycle of H. weldensis was completed in the laboratory using beetles, Tenebrio molitor (L.), as intermediate hosts, and pocket gophers of three genera (Geomys, Thomomys, and Pappogeomys) as definitive hosts. Development of H. weldensis did not …

The Development And Comparative Morphology Of The Mandibular Symphysis In Salamanders, Jennifer Lorenz Elwood

Biological Sciences Theses & Dissertations

Despite the extensive literature on salamander cranial morphology, few authors mention the structure or development of the mandibular symphysis. Adult specimens representing eight caudate families and larval Ambystoma opacum, representing nine developmental stages, were evaluated histologically to determine the structure and development of the mandibular symphysis.

From this analysis it was determined that early in the ontogeny of the mandibular symphysis Meckel's cartilages are separated by a band of undifferentiated cartilage. As development progresses, this band of undifferentiated cartilage gradually transforms into a wedge of fibrocartilage which fuses to Meckel's cartilages.

Symphyseal morphologies of the adult caudates could be broken …

BRANT AT FUNK LAGOON. Rick Peifer and I co-led a Bell Museum of Natural History (University of Minnesota) field trip to the Platte River ill March 1988. On 21 March about 25 of us went to Funk WPA (Phelps Co.) about 14:00, We found only a few thousand waterfowl, the remainder had apparently been driven off by USFWS personnel as a preventative measure against a further outbreak of fowl cholera. We were on the NI S road between sections 1 and 2, T6N, R17W, and saw only about 1,000 to 1,500 geese (mostly Canada’s, plus some White-fronted) plus a few …

White-Winged Dove In Dawson County, Lloyd G. Kaufman, Paul Kaufman

Nebraska Bird Review

On 3 July 1988, my wile and I saw a dove south of Cozad, Nebraska. We were driving at road speed, and not really bird watching. I caught a glimpse of white on the dove's wings as it flew and by the time I got stopped the dove circled about 0.25 mile away. We never got our binoculars on the dove at all, but we both noted the white trailing edge of the wings and on the tail. We are not sure enough to claim anything. I have been by there 15 to 20 times since then and have not …

Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller

Great Basin Naturalist

Thirty-eight accessions of 20 taxa (species and subspecies) of Chrysothamnus from a range of environments were grown in a uniform garden. During mid-June, terminal and lateral leaves were removed, fixed, and processed for light-microscopy studies. Area and perimeter measurements of ink tracings of midleaf vein cross sections were measured using computer-scan techniques. Leaf area and perimeter were compared with vein perimeter and area measurements. Area and perimeter of these Chrysothamnus leaves varied in response to the environment at the collection location. Plants native to hot, dry conditions had small, thick leaves, whereas plants native to cooler, more mesic conditions had …

Gibbon Classification: The Issue Of Species And Subspecies, Erin Lee Osterud

Dissertations and Theses

Gibbon classification at the species and subspecies levels has been hotly debated for the last 200 years. This thesis explores the reasons for this debate. Authorities agree that siamang, concolor, kloss and hoolock are species, while there is complete lack of agreement on lar, agile, moloch, Mueller's and pileated. The disagreement results from the use and emphasis of different character traits, and from debate on the occurrence and importance of gene flow.

A Light And Electron Microscopic Study Of The Rat Olfactory Tubercle: Normal Morphology And Acetylcholinesterase Localization, James Curtis Woodley

Biological Sciences Theses & Dissertations

A cytoarchitectural analysis of the rat olfactory tubercle using Nissl-stained coronal sections revealed that the dense cell layer (DCL) consisted of medium sized striatal cells in the cortical regions and small sized "granule" cells in the cap regions. Also delineated from this experiment was a rim of neuropil, nearly devoid of neurons as well as neuronal processes, outlining the islands of Calleja. Acetylcholinesterase (AChE) localization utilizing light microscopy revealed that the olfactory tubercles (OT) contained AChE-positive fibers that were orientated dorsoventrally in the molecular and multiform layers. The DCL consisted of only fibers en passant and putative terminals. Diisopropylfluorophosphate (DFP) …

Comparative Analysis Of The Effects Of Visual And Auditory Stimuli On Avian Mobbing Behavior, C. Ray Chandler, Robert K. Rose

Biological Sciences Faculty Publications

Both visual and auditory stimuli elicit avian mobbing behavior, but there is little comparative information on their isolated and additive effects. Using three combinations of two experimental stimuli (mount and tape of an Eastern Screech-Owl, Otus asio) we tested the effects of stimuli on the frequency, intensity, and duration of avian mobbing behavior. Of 169 mount-only trials, only 11 (6.5%) were successful in attracting birds. Tape-only (n = 169) and mount-and-tape (n = 170) were equally successful in attracting birds (approximately 85% of all trials), but mount-and-tape trials were more likely to initiate mobbing behavior. Birds responding …
