Differential Use Of Agricultural Fields And Rangeland Nesting Habitat By Mccown’S Longspur (Calcarius Mccownii) And Chestnut-Collared Longspur (Calcarius Ornatus) In Western Nebraska, Larry Snyder, Bartholomew L. Bly
Differential Use Of Agricultural Fields And Rangeland Nesting Habitat By Mccown’S Longspur (Calcarius Mccownii) And Chestnut-Collared Longspur (Calcarius Ornatus) In Western Nebraska, Larry Snyder, Bartholomew L. Bly
Nebraska Bird Review
The Nebraska Natural Legacy Plan (NNLP) lists both McCown's Longspur and Chestnut-collared Longspur as Tier I and Tier II species of conservation concern, respectively (Schneider et al. 2005). McCown's Longspur is listed as a Tier I species (highest conservation priority) in Nebraska because of regional population declines (Schneider et al. 2005), and because it is also listed on the Partners in Flight WatchList (Fitzgerald and Pashley 2000). The breeding distribution of McCown's Longspur in Nebraska is suggested to be the westernmost counties of the Panhandle (With 1994), although limited information on the breeding ecology of this species exists for Nebraska. …

Winter Field Report, December 2008 To February 2009, W. Ross Silcock
Nebraska Bird Review
This was one of the more "normal" winters for some time; I base this conclusion on the lack of unusually early or late dates or exceptional counts, as well as the lack of rarities. Although there were 11 species of gulls reported, perhaps we have become jaded by the gull extravaganza that is Lake McConaughy. It was a great winter for Common Redpolls and Snow Buntings as well, which was welcome as these birds do not appear in any numbers most winters. Perhaps the only group of birds that exhibited consistent aberration from the "norm" (I prefer "average") was the …

Fisheries Occasional Publication No.057 - Introduced Marine Species In Western Australia, Department Of Fisheries Western Australia
Fisheries Occasional Publications
As the largest State in Australia, Western Australia (WA) has a long and relatively pristine coastline that stretches over 12,500 km, or over 20,700 km if the State’s 3,747 islands are included. The coast ranges over 20 degrees of latitude from the temperate south coast to the northern tip of the tropical Kimberley. There are a wide variety of coastal marine habitats in this vast area. The south coast has extensive white sandy beaches interspersed with granite headlands. A diverse range of nearly 800 species of temperate marine algae, or seaweeds, occurs in the area. With 26 species, the seagrasses …
2008-2009 Christmas Bird Counts In Nebraska
2008-2009 Christmas Bird Counts In Nebraska
Nebraska Bird Review
Thirteen Christmas Bird Counts were held in Nebraska in the 2008–09 season, one less than last year. (Beaver Valley was not run this year.) This year fewer participants (184, the fewest since 2000) found more individual birds than last year (146,635 vs 133,106) but fewer species (126, the fewest since 2000).
Temperatures were about like last year, with an average high of 29°F. Most counts reported some snow cover, frozen still water, and some open running water. On the day of the Branched Oak–Seward count, a balmy 51°F was recorded in Lincoln shortly after midnight. By afternoon, the temperature had …

All Faculty Scholarship for the College of the Sciences
Infectious diseases are a significant threat to worldwide biodiversity. Amphibian declines, a significant part of current biodiversity losses, are in many cases associated with infectious disease. Water molds are one group of pathogens affecting amphibians on a worldwide basis. Although water molds have been studied extensively for their effects on host embryos, little information is available about how they affect post-embryonic amphibians. We tested the effects of one species of water mold, Saprolegnia ferax, in a comparative study of larvae of 4 amphibian species: Pseudacris regilla (Pacific treefrog), Rana cascadae (Cascades frog), Ambystoma macrodactylum (long-toed salamander), and R. aurora (red-legged …

Method Of Inhibiting Binding Activity Of Immunoglobulins, Clair D. Hicks, Zeynep Ustunol
Animal and Food Sciences Faculty Patents
A method for inhibiting culture agglutination in a fermentation medium including immunoglobulins includes the step of treating a source of immunoglobulins with an enzyme, such as papain, ficin, bromelain and mixtures thereof to hydrolyze the immunoglobulins into immunoreactive peptides having a molecular weight of less than 10,000 Daltons. This is accomplished utilizing ultrafiltration and/or diafiltration techniques. Next, is the collecting of peptides so produced and the adding of the peptides to a growth media for microorganisms useful in fermenting the fermentation medium. This is followed by growing the microorganisms in the inoculated growth media and adding the microorganisms grown in …

Four Decades Of Christmas Bird Counts In The Great Plains: Ornithological Evidence Of A Changing Climate, Paul A. Johnsgard, Thomas G. Shane
Papers in Ornithology
The rationale for this book has its origins in Terry Root’s 1988 Atlas of North American Wintering Birds, which provided a baseline landmark for evaluating the nationwide winter distributions of North American birds, using data from the National Audubon Society’s annual Christmas Bird Counts birds from 1962-63 through 1971-72. Tom Shane and I speculated that an updated analysis might shed light on the possible effects of more recent climatic warming trends on bird migration and wintering patterns in the Great Plains, a region known for its severe winters and also one of our continent’s important migratory pathways and wintering regions. …

Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon
Aquaculture Collection
A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or an unfamiliar social group, to two groups of noxiously treated rainbow trout, Oncorhynchus mykiss. In the predator cue experiment, fish were classified as bold or shy. Noxiously stimulated fish did not show antipredator responses, suggesting that pain is the imperative. In the social status experiment, noxiously stimulated fish held individually and undisturbed showed an increase in respiration rate and plasma cortisol. As a comparison, we used the dominant or subordinate fish …

Animal Science
A market basket survey for beef retail cut composition at the retail level (four stores each from two chains in each city) was conducted in 11 US cities from January to March 2006. Beef cuts (n = 17,495) were measured for external fat thickness with cuts from the chuck (0.05 cm), round (0.05 cm), and miscellaneous (0.04 cm) having less (P < 0.05) fat than cuts from the loin (0.11 cm) and rib (0.11 cm). Beef cuts (n = 1327) were separated physically into separable components with round cuts having more (P < 0.05) separable lean (96.63%) than chuck cuts (86.81%) and miscellaneous cuts (86.18%), which had more (P < 0.05) separable lean than loin cuts (84.53%) with rib cuts (69.34%) having the lowest (P < 0.05) separable lean. Chemical fat from the separable lean differed (P < 0.05) between each cut category: round cuts (3.71%), miscellaneous cuts (4.99%), loin cuts (5.60%), chuck cuts (6.90%), and rib cuts (8.61%). Ground beef samples (n = 235), with declared lean/fat percentages ranging from 73/27 to 96/4, had overall chemical fat values of 13.41% and moisture values of 67.42%. This survey documents the current beef retail cut and ground beef composition, which is helpful to those who need this information for various dietary and marketing purposes.

Fisheries Research Report No. 188 - Results Of The 2007 Survey Of The Albany Marine Area For Introduced Marine Species, Justin I. Mcdonald, Fred E. Wells, Michael J. Travers
Fisheries Research Reports
A survey of the Albany marine area (King George Sound, Princess Royal Harbour and Oyster Harbour) for introduced marine pest species was conducted in 2007. This survey was trialling the new system of monitoring for introduced marine pests developed by the National Introduced Marine Pests Coordination Group (NIMPCG). This study represents one of the first trials of this system (the first trial commenced in South Australia is still ongoing). In this survey fifty-two of the fifty-five potential pest species were targeted. Three species were excluded on the basis of salinity and/or temperature tolerances being exceeded. A wide variety of sampling …

Fisheries Research Report No. 183 - Development Of A Long-Term Program To Monitor Coastal Communities Within The Swan Region, Lynda M. Bellchambers
Fisheries Research Reports
Marine benthic communities along the metropolitan coast of Western Australia are varied and unique. The southward flowing Leeuwin Current brings warm water and tropical recruits whilst the cooler counter current, the Capes Current, brings the temperate recruits. The result is a mosaic of tropical species intermingled with the dominant temperate species. These areas sustain varied fish and invertebrate communities making this coast a highly desirable location for recreational and commercial use. Management strategies are in place that attempt to maintain the sustainability of this area including various fishery restrictions and the implementation of areas zoned as sanctuary zones (no-take). However, …

Fisheries Research Reports
This report summarises the performance indicators (PIs) and biological reference points (BRPs) developed from standardised catch per unit effort (SCPUE) models of the Western Australian abalone fisheries. It also outlines analysis and consultation processes used to construct these indicators. Other PIs, such as those relating to harvest rate and recruitment, will be developed when more fishery independent data becomes available.
A comprehensive 7-step process was utilised to develop PIs.
1) The Abalone Management and Advisory Committee (AbMac) considered options and advised that in the short-term, catch and effort trends be reviewed with other potential indicators to be considered at a …

Bulletins 4000 -
Sheep husbandry can be an interesting and rewarding activity but before starting to work with or buy sheep ask yourself if you are prepared to spend the time and effort to care for them.
Sheep cannot be placed in a paddock and forgotten. The sheep, along with their water, feed and fences must be inspected regularly. If you do not live on the farm, or visit it only infrequently, make sure there is a responsible person available who is willing to inspect and manage the sheep on your behalf.

Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts
Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts
Bulletins 4000 -
Sheep mortality during the first year of life is a large problem on many farms and poses a significant animal welfare issue for Australian agriculture. Post weaning mortality is estimated to cost the Australian sheep industry more than $89 million annually through reduced income, poor productivity and increased management expenses (Sackett et al. 2006).
A high mortality rate among weaners reduces the number of surplus animals available for sale and the number of potential breeding replacements. This, in turn, affects the selection intensity for desirable traits and the flock’s rate of genetic improvement.
Ill thrift and poor growth of weaner …

High levels of ciliate infestation can affect respiration, feed intake, and locomotion in farmed shrimps in the tropics. Information on seasonal variation of the infestation parameters of ciliates is scarce, but it would be useful for determining the suitability of preventive measures or therapeutic treatment if necessary. This study aimed to describe the prevalence and mean intensity of infestation (MII) of ciliates on wild native shrimps Penaeus (Farfantepenaeus) brasiliensis and P. (Farfantepenaeus) duorarum and farm-cultured juvenile shrimp Penaeus (Litopenaeus) vannamei over an annual cycle and to determine whether an association existed among physicochemical factors …
The Effects Of The Acetic Acid “Pain” Test On Feeding, Swimming, And Respiratory Responses Of Rainbow Trout (Oncorhynchus Mykiss): A Critique On Newby And Stevens (2008), Lynne U. Sneddon
Experimentation Collection
Newby and Stevens’ (2008) paper ‘‘The effects of the acetic acid ‘pain’ test on feeding, swimming, and respiratory responses of rainbow trout (Oncorhynchus mykiss)’’ examines the effects of a noxious stimulus on the behaviour of trout in an attempt to replicate research conducted in my laboratory (Sneddon, 2003a; Sneddon, 2007; Sneddon et al., 2003a,b; Reilly et al., 2008). However, the authors used a different protocol to the one already published and I would like to respond to some of their points of discussion to provide scientific explanations for their results using data from my laboratory. The authors show that swimming …

Teff: What Is It? Where Does It Fit In Kentucky, Bret Winsett
Teff: What Is It? Where Does It Fit In Kentucky, Bret Winsett
Forage Symposium at the Kentucky Cattlemen’s Convention
Teff (Eragrostis tef (zucc)) is an annual, warm season grass native to Ethiopia. Throughout its history, teff has been used more as a gluten-free grain for flour than as forage. However, in recent years, forage agronomists and producers have become increasingly interested in its potential contribution as a hay crop. Teff is characterized by a fairly large crown, many tillers, fine stems, a very shallow root system, rapid growth and high tonnage capability. During the vegetative stage, teff plants look somewhat similar to tall fescue in size and color. Teff tends to germinate quickly with good moisture, regrow quickly after …

Weed Control Options For Pastures, Jon Doran
Forage Symposium at the Kentucky Cattlemen’s Convention
What is a weed? A pasture or hayfield “weed” is any plant that you deem as being out of place and/or a plant that is decreasing your desired forage production. Weeds may be classified in several ways including broadleaf weeds, woody plants, and undesirable grasses. Besides decreasing forage, weeds can also interfere with forage utilization, grazing distribution, etc. There are several methods available to control weeds and increase production of and access to desirable forages. The three main methods are cultural, mechanical, and chemical. The cultural method is quite simple-a thriving grass stand is an excellent form of weed control …

Selecting Clover Varieties Wisely, S. Ray Smith
Forage Symposium at the Kentucky Cattlemen’s Convention
Although there are not a lot of new red clover varieties, several companies and Universities have active red clover breeding programs. In some ways, red clover is the easiest species to make variety recommendations for. Simply put, “only plant certified seed of improved varieties, never plant common seed.” University of Kentucky research has shown that the difference between improved varieties and common seed can be 6000 to 10,000 lb/acre in higher yield and 1 to 1 ½ years longer stand life. Sometimes you may “luck up” and find that the bag of cheap common seed you purchased was actually an …
