Mother-Young Recognition In An Ungulate Hider Species: A Unidirectional Proce, Marco V.G. Torriani, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Parent‐offspring recognition is usually crucial for survival of young. In mammals, olfaction often only permits identification at short range, and vocalizations are important at longer distances. Following and hiding antipredator strategies found in newborn mammals may also affect parental recognition mechanisms. We investigated mother‐offspring recognition in fallow deer, an ungulate hider species. We analyzed the structure of adult female and fawn contact calls to determine whether they are individually distinctive and tested for mother‐offspring recognition. Only females (and not fawns) have individualized vocalizations, with the fundamental frequency as the most distinctive parameter. Playback experiments showed that fawns can distinguish the …

Fisheries Research Report No. 158 - An Assessment Of The Blue Swimmer Crab Fishery In Geographe Bay, Lynda M. Bellchambers, K. D. Smith, D. Harris

Fisheries Research Reports

The study was undertaken to provide detailed information on blue swimmer crabs in Geographe Bay so that the recreational and commercial fishery issues could be addressed using more accurate data than was previously available. A ministerial decision that banned commercial fishing for blue swimmer crabs in Geographe Bay was made in January 2005 while this study was underway. The intention of this report was to provide a summary of information on crab stocks in the region, not to alter the current management arrangements. This report describes experimental sampling, commercial catch statistics, commercial catch monitoring and surveys of recreational fishers to …

Habitat Characteristics Of Spring Blackbird Roosts In East-Central South Dakota, H. Jeffrey Homan, Richard S. Sawin, George M. Linz, William J. Bleier

The Prairie Naturalist

In the northern Great Plains, blackbirds (Icteridae) roost almost exclusively in emergent-dominated wetlands. The physical characteristics of wetland roosts are not well understood. From March 20 to April 20, 1999, we studied 16 wetlands used as blackbird roosts in east-central South Dakota. Six wetlands had major roosts (range: 102,000-298,000 blackbirds); whereas, 10 wetlands had minor roosts (range: 2,010-34,000 blackbirds). Maximum roost size was correlated directly with emergent vegetation area (P = 0.05) and possibly with wetland basin area (P ≤ 0.10). Water depths were greater at used sites within wetlands of major roosts (median = 44 cm) than …

Aerial Searches For Whooping Cranes Along The Platte River, Nebraska, John G. Sidle, Wallace G. Jobman, Craig A. Faanes

Nebraska Bird Review

The endangered Whooping Cranes (Grus americana) that migrate between Wood Buffalo National Park, Alberta and Northwest Territories, and the Aransas National Wildlife Refuge Area, Texas, roost at many aquatic stopover locations (Austin and Richert 2001) including the central Platte River, Nebraska (Johnson 1982; Lingle et al. 1984, 1986, 1991; Faanes et al. 1992; Richert 1999). Under the U.S. Endangered Species Act, 90 km of the central Platte have been designated as critical habitat for the Whooping Crane, although suitable Platte River habitat for Whooping Crane and Sandhill Crane (Grus canadensis) continues to decline (Sidle et al. …

Letter Of Information' Excerpts

Nebraska Bird Review

In the early years of the Nebraska Ornithologists' Union, which was founded in 1899, the organization published its Proceedings, yearly through 1902 and less frequently for the following 13 years. Beginning in 1916, the NOU allied itself with the Wilson Ornithological Club, and its annual proceedings were published by that organization for the next nine years. In 1925, distribution of a mimeographed "Letter of Information" began, with NOU Secretary-Treasurer Myron H. Swenk acting as editor. These Letters, which contain announcements, accounts of meetings and field trips, and notes on bird sightings from members, were published through 1932. They bridged …

Summer Field Report, June-July 2006, W. Ross Silcock

Nebraska Bird Review

Under "Old Business", numbers of Black-capped Chickadees are beginning to recover, but several observers mentioned that American Crows and, most recently, Black-billed Magpies are still suffering lowered numbers. On the plus side, Scissor-tailed Flycatchers continue in increasing numbers, including a pair (or at least one of a pair) that returned to the same location where they nested successfully last year and succeeded again this year.

And now ''New Business". Evidence came to hand that both Western and Clark's Grebes may have suffered poor breeding success due to poor water conditions at traditional breeding sites. An intriguing observation on 28 Jul …

White-Cheeked Geese In Nebraska, W. Ross Silcock

Nebraska Bird Review

The intent of this paper is to summarize the current state of knowledge regarding "White-cheeked Goose" is used in reference to the various taxa included within the two species Canada Goose (Branta canadensis) and Cackling Goose (B. hutchinsii), as constituted by the American Ornithologist' Union (AOU; 2004). Using culmen measurements, confirmation of both species' and the "expected" subspecies' occurrence in Nebraska was documents, but culmen measurements alone could not confirm the occurrence of any of the "unexpected" subspecies.

TAXONOMY

As many as 10 subspecies of White-cheeked Goose were described by the AOU (1957), five of which ( …

An ∼140-Kb Deletion Associated With Feline Spinal Muscular Atrophy Implies An Essential Lix1 Function For Motor Neuron Survival, John C. Fyfe, Marilyn Menotti-Raymond, Victor A. David, Lars Brichta, Alejandro A. Schaffer, R. Agarwala, William J. Murphy, William J. Wedemeyer, Brittany L. Gregory, Bethany G. Buzzell, Meghan C. Drummond, Brunhilde Wirth, Stephen J. O'Brien

Biology Faculty Articles

The leading genetic cause of infant mortality is spinal muscular atrophy (SMA), a clinically and genetically heterogeneous group of disorders. Previously we described a domestic cat model of autosomal recessive, juvenile-onset SMA similar to human SMA type III. Here we report results of a whole-genome scan for linkage in the feline SMA pedigree using recently developed species-specific and comparative mapping resources. We identified a novel SMA gene candidate, LIX1, in an ~140-kb deletion on feline chromosome A1q in a region of conserved synteny to human chromosome 5q15. Though LIX1 function is unknown, the predicted secondary structure is compatible with …

Artificial Burrows And The Deer Mouse: Do Number Of Entrances Influence Use?, Glennis A. Kaufman, Donald W. Kaufman

The Prairie Naturalist

We examined use of artificial burrows by the deer mouse (Peromyscus maniculatus) in mixed grass prairie in north central Kansas. We predicted differential use of burrows, such that the deer mouse would prefer two entrance burrows in non-winter months when predatory snakes were active, but prefer one entrance burrows in winter when cold, windy conditions existed. We installed 20 pairs of artificial burrows (one single entrance and one double entrance) in summer 1988. We examined these burrows on seven dates from autumn 1988 to autumn 1989. All mice (n = 70) used two entrance burrows at least …

Evaluating Genetic Viability Of Pronghorn In Wind Cave National Park, Jonathan A. Jenks, Christopher N. Jacques, Jaret D. Sievers, Robert W. Klaver, R. Terry Bowyer, Daniel E. Roddy

The Prairie Naturalist

The pronghorn (Antilocapra americana) was reintroduced into Wind Cave National Park, South Dakota, in 1914 and thus, has inhabited the Park for almost a century. A decline in the population has raised concern for the continued existence of pronghorn inside Wind Cave National Park. Historically, pronghorn numbers reached greater than 300 individuals in the 1960's but declined to about 30 individuals by 2002. The primary objective of our study was to evaluate genetic characteristics of pronghorn to determine if reduced heterozygosity contributed to the decline of pronghorn in Wind Cave National Park. Microsatellite DNA was collected from 75 …

Rana Ocellata Linnaeus, 1758 (Currently Leptodactylus Ocellatus; Amphibia, Anura): Proposed Conservation Of Usage Of The Specific Name By The Designation Of A Neotype, W. Ronald Heyer, Ulisses Caramaschi, Rafael O. De Sá

Biology Faculty Publications

The purpose of this application, under Article 75.6 of the Code, is to conserve the usage of the specific name of Rana ocellata Linnaeus, 1758 for a species of leptodactylid frog from South America by the designation of a neotype. Prevailing usage of the name is threatened by the identity of the type specimen which is a different species than that which is currently known as Leptodactylus ocellatus. It is proposed that all name-bearing types be set aside and a neotype designated in accord with prevailing usage.

Seasonal Territoriality In The Carolina Wren, Thryothorus Ludovicianus, To Visual And Vocal Stimuli., Mark Allen Dunaway

Electronic Theses and Dissertations

Carolina Wrens, Thryothorus ludovicianus, are permanent residents throughout their range. They form pair bonds at a young age, maintain these bonds for multiple years, and defend feeding/breeding territories year round. Male Carolina Wrens use songs in territorial defense and have been shown to countersing regularly to both neighbors and intruders. They use various song characteristics to determine the location of another bird and whether its territory has been invaded.

Wrens often approach playbacks silently in apparent searching behavior. In some cases, birds will investigate the playback but fail to countersing. I wanted to determine whether or not wrens would …

The Fisheries Of The Lower Columbia River, 1792 To 1850, Based On Euroamerican Explorer And Fur Company Accounts, Michael A. Martin

Dissertations and Theses

The role of fish in the Native American economy of the lower Columbia River has never been considered in detail. My study focused on the Columbia River from its mouth to the Cascades and the Willamette River from its confluence with the Columbia to Willamette Falls. For this study I asked: How was salmon used? What other fish were important? Where and how were these fish taken and used?

To address these questions, I evaluated historical documents, including explorer's accounts and the administrative records of fur companies dating from the late 1700's through the 1850's. I used fishery data, physical …

Modulation Of Intraoral Subambient Pressure And Feeding Behavior Relative To Prey Type In The Largemouth Bass, Micropterus Salmoides Floridanus, Sarah Legates

Masters Theses & Specialist Projects

Variation, or modulation, of suction feeding performance across two prey location treatments, as measured by peak subambient pressure generation, was studied in the Florida largemouth bass, Micropterus salmoides floridanus. Previous studies of suction feeding in centrarchids have excluded possible sources of performance variation to minimize the modulatory response. Florida bass are known to modulate their feeding kinematics when exposed to prey at different levels of elusiveness, and were in turn predicted to vary suction pressure generation when exposed to these conditions. Eight bass fed Palaemonetes sp. shrimp in an open water (elusive) setting and in a vegetated (non-elusive) setting were …

Strategies For Reducing Mosquito-Borne Disease Vulnerability In Equine Populations: A Kentucky Case Study, Sara Dalton

Masters Theses & Specialist Projects

This research examined equine management practices that limit or contribute to the spread of West Nile virus and other mosquito-bome disease. I hypothesize that there is a relationship between equine management practices and outbreaks of mosquito-borne disease in horse populations. Improved and appropriate mosquito habitat management may limit the risk of mosquito-borne disease in humans and horses by helping to lower the mosquito populations. The study goals were to recognize equine management practices and mosquito prevention practices that foster outbreaks of mosquito-borne disease. This study used a questionnaire for county level analysis of equine management practices and the relationship to …

National Pork Producers Council Maternal Line National Genetic Evaluation Program: A Comparison Of Sow Longevity And Trait Associations With Sow Longevity, T. Serenius, K. J. Stalder, T. J. Baas, J. W. Mabry, R. N. Goodwin, R. K. Johnson, O. W. Robison, M. Tokach, R. K. Miller

Department of Animal Science: Faculty Publications

Data from the National Pork Producers Council Maternal Line National Genetic Evaluation Program were used to compare longevity of sows from 6 commercial genetic lines and to estimate the phenotypic associations of sow longevity with gilt backfat thickness, ADG, age at first farrowing, litter size at first farrowing, litter weight at first farrowing, average feed intake during lactation, and average backfat loss during lactation. The lines evaluated were American Diamond Genetics, Danbred North America, Dekalb-Monsanto DK44, Dekalb-Monsanto GPK347, Newsham Hybrids, and National Swine Registry. The data set contained information from 3,251 gilts, of which 17% had censored longevity records (sows …

Characterization Of Membrane Potentials In Vascular Smooth Muscle Of Hagfish, Lamprey And Trout, Prentiss Jones Jr.

Dissertations

The objective of this study was to characterize membrane potentials in systemic arteries of Pacific hagfish, Eptatretus stouti, Rainbow trout, Onchorhyncus mykiss, and Sea lamprey Petromyzon marinus. Previous studies have characterized membrane potentials in piscine tissue. However, these studies utilized non-vascular tissues such as cardiac muscle and skeletal muscle (69, 161). Characterization of membrane potentials in fish vasculature is without precedent in the literature. The hypothesis of this study was that membrane potentials in fish vascular smooth muscle differ little between species when comparable vasculature is evaluated.

Predicted Responses Of Small Mammals To Reintroduction Of Fire Along A Northern Prairie River Valley, Aren Eddingsaas, Robert Murphy, Patrick Isakson, Keith Behrend

United States Fish and Wildlife Service: Publications

Fire is being reintroduced to restore native mixed-grass prairie that has been invaded by woody vegetation and introduced species of grasses at 8000-ha (20,000-ac) Des Lacs National Wildlife Refuge (NWR) in northwestern North Dakota. Implications of this management for much of the local fauna are merely speculative without basic inventory data. We measured the occurrence and habitat relationships of small mammals (< 450 g [< 1 lb]) in prairie and woodland on the refuge. Using snaptraps, we captured 7 mammal species on 42 75-m (245-ft) radius plots in prairie during summer 1998 (n = 193 individuals in 5,208 trap-nights) and 5 species on 32 11-m (36-ft) radius plots in woodland during summer 2000 (n = 289 individuals in 2,560 trap-nights). We found 13-lined ground squirrel (Spermophilus tridecemlineatus) and western jumping mouse (Zapus princeps) almost exclusively in open prairie and southern red-backed vole (Clethrionomys gapperi) almost exclusively in woodland. Based on logistic regression analysis, occurrence of 13-lined ground squirrel …

Long-Term Abundance Of Breeding Songbirds During Restoration Of Northern Mixed-Grass Prairie, Robert Murphy, Karen Smith

United States Fish and Wildlife Service: Publications

There are no published, long-term accounts of responses of grassland passerine birds to the restoration of northern mixed-grass prairie through combined use of fire and grazing. During 1979-2001, we assessed abundance of passerine birds (9 grassland species and 1 shrub-associate species) on 2 brush-invaded, mixed-grass prairie tracts at Lostwood National Wildlife Refuge in northwestern North Dakota. Each tract encompassed 90 ha (220 ac) that were being restored through 4 prescribed fires then 3 consecutive years of grazing by cattle. Fires were separated by 2-4 years of rest (i.e., nondisturbance) and grazing was initiated 2 years after the last fire. Among …
