Predators And Life Histories Shape Lestes Damselfly Assemblages Along A Freshwater Habitat Gradient, Robby Stoks, Mark A. Mcpeek Oct 2002

Predators And Life Histories Shape Lestes Damselfly Assemblages Along A Freshwater Habitat Gradient, Robby Stoks, Mark A. Mcpeek

Dartmouth Scholarship

Survey data from New England showed that assemblages of Lestes dam- selflies are organized along the entire gradient of pond permanence and predator presence. One assemblage occupies vernal ponds lacking large dragonfly predators and fish; four are largely confined to temporary ponds that typically contain dragonfly predators; one dom- inates fishless permanent ponds and lakes where dragonflies are the top predators; and one dominates permanent ponds and lakes where fish are the top predators. We determined the role of life history and predation in maintaining this striking pattern by conducting a series of transplant experiments in the field and a …

Impact Of The Agricultural Sector On The Arkansas Economy, H. L. Goodwin Jr., Jennie Popp, Wayne Miller, Gina Vickery, Z. Clayton-Niederman

AAES Research Reports and Research Bulletins

Agriculture historically has been one of the primary sectors of the Arkansas economy. Agriculture is defined as the sum of agricultural, forestry, and fisheries production and processing activities unless otherwise specified. Not only does agriculture contribute to the economy through direct agricultural production and added value processing, it also plays an important role through the economy’s other sectors. Utilizing data from the United States Bureau of Economic Affairs and the State of Arkansas, the economic impact of agriculture on the Arkansas economy was estimated for the latest year available, 1999. Gross State Product (GSP) information for Arkansas was compared with …

Mapping Intramuscular Tenderness Variation In Four Major Muscles Of The Beef Round, B.J. Reuter, D.M. Wulf, R.J. Maddock Oct 2002

Mapping Intramuscular Tenderness Variation In Four Major Muscles Of The Beef Round, B.J. Reuter, D.M. Wulf, R.J. Maddock

Animal Science Faculty Publications

The objective of this study was to quantify intramuscular tenderness variation within four muscles from the beef round: biceps femoris (BF), semitendinosus (ST), semimembranosus (SM), and adductor (AD). At 48 h postmortem, the BF, ST, SM, and AD were dissected from either the left or right side of ten carcasses, vacuum packaged, and aged for an additional 8 d. Each muscle was then frozen and cut into 2.54- cm-thick steaks perpendicular to the long axis of the muscle. Steaks were broiled on electric broilers to an internal temperature of 71°C. Location-specific cores were obtained from each cooked steak, and Warner- …


The Effect Of A Predator Gradient On Female Oviposition Site Selection And Larval Performance, Josef F. Rieger Oct 2002

The Effect Of A Predator Gradient On Female Oviposition Site Selection And Larval Performance, Josef F. Rieger

Biological Sciences Theses & Dissertations

Patterns of larval amphibian distribution and abundance have historically been ascribed to direct predation. However, adult oviposition site selection is an alternative mechanism that can produce identical patterns and significantly influence community assembly. Although such behavioral habitat selection has been documented in several amphibian species whose larvae lack particular anti-predator defenses, the sensitivity of adult amphibians in detecting predator cues and avoiding these habitats has not yet been determined. If larval survivorship is greatly reduced in sites containing predatory fish, selection to detect and avoid habitats with low fish densities should be strong. I conducted three experiments which, (1) evaluated …


Maternal Behavior In Mice Selected For Large Litter Size, Chung-Feng Chiang, Rodger . K. Johnson, Merlyn K. Nielsen Sep 2002

Maternal Behavior In Mice Selected For Large Litter Size, Chung-Feng Chiang, Rodger . K. Johnson, Merlyn K. Nielsen

Department of Animal Science: Faculty Publications

A total of 96 lactating mice and their pups from each of three replications of lines selected 21 generations for increased litter size (LS) followed by 23–25 generations of random selection and contemporary unselected control lines (LC) were characterized for maternal behavior. Sixteen dams and their pups from each replication of LS and LC lines were sampled. Litter sizes at birth for LS versus LC in the first, second, and third replicates were 17.3 versus 13.2, 15.9 versus 13.1, and 12.3 versus 10.6 pups, respectively, with LS dams averaging 2.87 ± .70 pups more. One-half of the litters were standardized …

Hermit Warbler In Knox County: First Accepted Record For Nebraska, Mark A. Brogie Sep 2002

Hermit Warbler In Knox County: First Accepted Record For Nebraska, Mark A. Brogie

Nebraska Bird Review

The 2002 Nebraska Ornithologists' Union Record Committee has reviewed the following record and accepted it as a Class III. This Knox County sighting constitutes the first confirmed record of Hermit Warbler in Nebraska.

On 15 May, 2002, while birding with Ben Brogie, we stopped at an isolated planting of mixed hardwoods and Ponderosa Pine (Pinus ponderosa) on a high hill 5.5 miles north (Road 530) of Creighton. We noticed several birds moving among the branches along the roadside and upon "spishing" for just a few seconds we attracted a female Cape May Warbler (Dendroica tigrina) and …


The Changing Status Of Sandhill Crane Breeding In The Eastern Rainwater Basin, Joel G. Jorgensen Sep 2002

The Changing Status Of Sandhill Crane Breeding In The Eastern Rainwater Basin, Joel G. Jorgensen

Nebraska Bird Review

Prior to extirpation as a breeder before 1 900, the Sandhill Crane (Grus canadensis) formerly bred throughout Nebraska (Bruner et al. 1 904; Ducey 1988; Sharpe et al. 2001). During the 1990s, several summer observations of Sandhill Crane in the Eastern Rainwater Basin region of south-central Nebraska suggested the probability of breeding. In 1999, I discovered direct breeding evidence at Harvard Waterfowl Production Area, Clay County. This breeding record, along with another by different observers in the same county during the same season are the first modern breeding records for Nebraska. In this note, I describe my observations, …

Summer Field Report, June-July 2002, W. Ross Silcock Sep 2002

Summer Field Report, June-July 2002, W. Ross Silcock

Nebraska Bird Review

The big news this summer was the drought which affected most of southern and western Nebraska. Conditions were particularly severe in the southern Panhandle and in the southwest. As one observer (DP) wryly noted: "The cool, cloudy weather in the sixties this morning was a welcome contrast to the stinkin' hot dirt blowing blast furnace in the low one hundreds that was in south central Nebraska Sunday afternoon [June 3]." Some comments from western Kansas by birder-rancher Scott Seltman are pertinent: "I think there's no question that because of the ongoing drought most farmers delayed their fieldwork this spring" perhaps …

Summer Field Report Last Page September 2002

Nebraska Bird Review

White-winged Crossbill: The remarkable winter influx persisted into the summer period, with one seen in Omaha- the last at the observer's feeders- on 1 June (NR), and a female identified as late as 20 June at a Bassett feeder where none had showed since 9 June (CH). These sightings signify record late spring dates (although there are a few isolated summer records); both locations had hosted significant wintering flocks.

Mitochondrial Dna And The Origins Of The Domestic Horse, Thomas Jansen, Peter Forster, Marsha Levine, Hardy Oelke, Matthew Hurles, Colin Renfrew, Jürgen Weber, Klaus Olek Aug 2002

Mitochondrial Dna And The Origins Of The Domestic Horse, Thomas Jansen, Peter Forster, Marsha Levine, Hardy Oelke, Matthew Hurles, Colin Renfrew, Jürgen Weber, Klaus Olek

Genetics Collection

The place and date of the domestication of the horse has long been a matter for debate among archaeologists. To determine whether horses were domesticated from one or several ancestral horse populations, we sequenced the mitochondrial D-loop for 318 horses from 25 oriental and European breeds, including American mustangs. Adding these sequences to previously published data, the total comes to 652, the largest currently available database. From these sequences, a phylogenetic network was constructed that showed that most of the 93 different mitochondrial (mt)DNA types grouped into 17 distinct phylogenetic clusters. Several of the clusters correspond to breeds and/or geographic …

Within-Litter Birth Weight Variation In The Domestic Pig And Its Relation To Pre-Weaning Survival, Weight Gain, And Variation In Weaning Weights, Barry N. Milligan, David Fraser, Donald L. Kramer Aug 2002

Within-Litter Birth Weight Variation In The Domestic Pig And Its Relation To Pre-Weaning Survival, Weight Gain, And Variation In Weaning Weights, Barry N. Milligan, David Fraser, Donald L. Kramer

Ontogeny Collection

To determine the relationship between within-litter birth weight variation and pre-weaning survival and weight gain, and to provide practical guidance on fostering low-birth-weight piglets, we analyzed piglet survival and weight gain in litters of piglets from 52 sows followed through eight consecutive parities. Litters with high variation in birth weight had more deaths, especially if the litter’s mean birth weight was low. High variation in birth weight was also associated with high variation in weaning weight, but was not significantly related to mean weaning weight. Piglets with birth weights well below the range of most of the litter (‘low-birth-weight piglets’) …


Fisheries Research Report No. 132 - A Review Of Food Availability, Sea Water Characteristics And Bivalve Growth Performance At Coastal Culture Sites In Temperate And Warm Temperate Regions Of The World, Sidney A. Saxby Aug 2002

Fisheries Research Report No. 132 - A Review Of Food Availability, Sea Water Characteristics And Bivalve Growth Performance At Coastal Culture Sites In Temperate And Warm Temperate Regions Of The World, Sidney A. Saxby

Fisheries Research Reports

The suitability of a coastal area for bivalve farming, as well as the density at which bivalves can be farmed in that area, is limited by the available food supply and other environmental variables. In this review, a range of successful and marginal bivalve growing areas in temperate and warm temperate coastal areas around the world are characterised. These include areas of high food and nutrient levels, such as Saldanha Bay in South Africa, and the Seto Inland Sea, Japan, through to more oligotrophic areas, typified by parts of the South Australian coastline and the Mediterranean Sea. The latter areas …


Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg Aug 2002

Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg

Fisheries Management Papers

The Department of Fisheries does not want to embark on what is ‘new territory’ in Western Australia without a policy framework to define what is to happen, why it is to happen, and what will happen if the project does or does not succeed. This paper therefore attempts to do three things. 1. It sets in place accepted definitions of reseeding and stock enhancement within the general context of fisheries management in Western Australia. 2. It discusses the policy issues associated with reseeding grazing gastropods and bivalves into the natural environment. 3. It proposes a framework or process to be …


Estimating Population Numbers Of Black Bears (Ursus Americanus) In Eastern Kentucky Using Microsatellite Analysis, Kelly Vowels Aug 2002

Estimating Population Numbers Of Black Bears (Ursus Americanus) In Eastern Kentucky Using Microsatellite Analysis, Kelly Vowels

Masters Theses & Specialist Projects

Black bears (Ursus americanus) occur sporadically in eastern Kentucky, and there is some evidence that a breeding population exists. In order to establish management practices to enhance the black bear population in Kentucky, information about this population is needed. However, until recently, no population size estimate has been available. Gathering information on black bears is difficult because black bears are elusive animals. The development of new molecular methods has made it easier to track and gather information on black bear populations, including estimates of population size. Molecular markers are particularly useful in that they do not require physical contact with …

Technical Note: The Effect Of Freezing On Warner-Bratzler Shear Force Values Of Beef Longissimus Steaks Across Several Postmortem Aging Periods, B.C. Shanks, D.M. Wulf, R.J. Maddock

Animal Science Faculty Publications

The objective of this study was to compare fresh and frozen protocol procedures for Warner- Bratzler shear force (WBSF) determination on steaks aged for different periods of time. The fresh protocol consisted of measuring WBSF on steaks cooked on the exact day the aging period ended. The frozen protocol consisted of measuring WBSF on steaks that were aged, frozen (−16°C) for approximately 2 mo, thawed for 24 h, and then cooked. Twenty-two strip loin steaks from each of 20 crossbred heifers and steers were individually vacuum-packaged and assigned to either the fresh or frozen protocol and one of 11 aging …


A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer Aug 2002

A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer

School of Natural Resources: Dissertations, Theses, and Student Research

The need to accurately assess the use and suitability of elk (Cervus elaphus spp.) habitat at regional scales will continue to increase as human development encroaches into what was once optimum elk habitat. The objectives of this research were to calculate the relative proportions of habitat use by elk in the Pine Ridge region of Northwestern Nebraska from a set of radio-collared elk locations and generate a habitat suitability model. Habitat variables (Iandcover type, aspect, slope, distance to a road, road density, and distance from the ponderosa pine edge) were measured for each elk location (n = 5,787 dating …

Effect Of Duration Of Performance Test On Variance Component Estimates For Lamb Growth Rate, G. D. Snowder, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The objective was to determine the effect of periods of adjustment and duration of performance test on estimating genetic variance parameters for ADG. Variance components were estimated from ADG data collected from 1978 to 1984 on a total of 1,047 Targhee ewe and ram lambs at the U.S. Sheep Experiment Station (Dubois, ID). Across all years, lambs averaged 84 ± 9 d of age and 25 ± 5.4 kg of weight when placed on test. Lambs were provided ad libitum access to a commercial pellet of barley grain and ground alfalfa for 14 wk. Every 2 wk, ADG was recorded. …
