Fisheries Research Report No. 152 - Development Of A Dna Database For Compliance And Management Of Western Australian Sharks., Rory Mcauley, K. Ho, R. Thomas

Fisheries Research Reports

Final FRDC Report - Project 2003/067

The capability to identify individual shark species from processed body parts is necessary for the WA Department of Fisheries to ensure the compliance of all WA fisheries with both existing protected species regulations and proposed new management measures for commercially important shark species. This project established a reference database of genetic profiles or ‘fingerprints’ for nine of Western Australia’s protected and commercially important shark species. Fingerprints from a 10th species, the shortfin mako (Isurus oxyrinchus) could not be obtained due to probable primer sequence mismatching. The database, in conjunction with an associated inspection and …

Fisheries Research Report No. 151 - Biology And Stock Assessment Of The Thickskin (Sandbar) Shark, Carcharhinus Plumbeus, In Western Australia And Further Refinement Of The Dusky Shark, Carcharhinus Obscurus, Stock Assessment., Rory Mcauley, R Lenanton, J. Chidlow, R. Allison, E. Heist

Fisheries Research Reports

Final FRDC Report - Project 2000/134

The purpose of this project was to collect the biological and fishery information necessary to conduct a stock assessment of the sandbar (known locally as ‘thickskin’) shark, Carcharhinus plumbeus and to improve and update the existing stock assessment for the dusky shark, Carcharhinus obscurus. Results from this project have already been used by the Western Australian Department of Fisheries to determine appropriate management arrangements for the State’s shark fisheries to ensure the sustainable exploitation of these species. Results have also assisted the WA target-shark fisheries in conducting Ecologically Sustainable Development (ESD) assessment in order …

Suggested Areas For Study, William F. Rapp Jr.

Nebraska Bird Review

After 100 years of organized ornithology we have a good picture of the bird fauna of Nebraska. Yes, we will still be able to add new species to the state list, but this will become more and more difficult. What problems are left for the amateur ornithologist to solve? Nebraska is a big state with many different ecological areas, few of which have been studied in detail. Only a few areas of the state have been well studied. Not only do we need data on what species occur, but how many. This type of study can be done by amateur …

Comparing Immune Responses Of Juvenile And Adult Northern Fence Lizards, Sceloporus Undulatus, Zaïna Sandrine Kabange

All-Inclusive List of Electronic Theses and Dissertations

Sex steroid hormones affect behavior and morphological traits important in sexual selection. Steroid hormones also play a role in the development and functioning of immune system components. The immunocompetence handicap hypothesis (Folstad and Karter, 1992) proposes that tradeoffs, mediated by plasma levels of testosterone, exist between the immune system and elaboration of secondary sexual traits. Endocrine-immune interactions are well documented in birds and mammals, and steroid hormones can be immunoenhancing or immunosuppressive. Relatively little work has examined the ontogeny of immune function, and the interactions between steroid hormones and the immune system in reptiles. The first experiment addressed the question …

Intramuscular Tenderness Variation Within Four Muscles Of The Beef Chuck, G.A. Searls, R.J. Maddock, D.M. Wulf

Animal Science Faculty Publications

The i.m. tenderness variation was examined within four beef chuck muscles, the infraspinatus (IF), supraspinatus (SS), triceps brachii (TB), and serratus ventralis (SV). The IF, SS, TB, and SV muscles were cut into 2.5 cm thick steaks perpendicular to the long axis of the muscle. An identification tag was placed on each steak, consisting of a muscle identification number, steak number, and orientation of the steak. Steaks were vacuum-packaged and stored at −22°C until subsequent analysis. Steaks were thawed at 1°C and cooked on electric broilers to an internal temperature of 71°C. One core was removed from each 2.5-cm × …

Fall Field Report, August–November 2005, W. Ross Silcock

Nebraska Bird Review

This fall was notable for its lack of notable events; numbers of migrants reported in all species groups, especially waterfowl, shorebirds, and warblers, were low. Lingering birds were both insectivores and seed-eaters, and, coupled with a rather stable fall weather-wise, it seems that there were no disturbances to concentrate birds or otherwise impede a steady flow of migrants through the state. Without concentrations, migrants are often not noticed or, more accurately here, not reported by observers.

The best Western Grebe count was 2500, very low relative to expected high fall counts of at least 20,000. Mergansers were the only bright …

Fall Field Days At Harlan County Reservoir

Nebraska Bird Review

The annual Fall Field Days were held on September 9–11, 2005, at the 4-H Camp near Alma. Field trip destinations included Harlan County Reservoir and various other points of interest in Furnas, Harlan, Franklin, Phelps, Kearney, and Adams Counties. The total tally was 119 species, including Snowy Egret, Yellow-crowned Night-Heron, Mississippi Kite, Prairie Falcon, and Olive-sided Flycatcher.

Fifty-four members and guests attended. On Friday the group heard from Dr. Josef Kren on the topic of obligate brood parasites, species that have lost the ability to construct nests and incubate eggs and instead lay eggs in the nests of other species, …

Snowy Plover Nesting At Lake Mcconaughy In 2004 And 2005, Mark M. Peyton, Gabriel Wilson

Nebraska Bird Review

The Snowy Plover (Charadrius alexandrinus) is a small shore bird that upon casual observation resembles the Piping Plover (Charadrius melodus). The most obvious differences are in the dark beak and legs of the Snowy Plover in contrast to the orange bill with the black tip and orange legs of the Piping Plover. The two also have strikingly different calls (pers. obs.). In Nebraska the Piping Plover can be found along the Missouri, Platte, Niobrara, Loup, and Elkhorn Rivers and the sandpits associated with those rivers (Haig and Plissner 1993). Piping Plovers are also common along the …

Plumage Convergence In Picoides Woodpeckers Based On A Molecular Phylogeny, With Emphasis On Convergence In Downy And Hairy Woodpeckers, Amy C. Weibel, William S. Moore

Biological Sciences Faculty Research Publications

Adult and juvenile plumage characters were traced onto a well-resolved molecular based phylogeny for Picoides woodpeckers, and a simple phylogenetic test of homology, parallelism, and convergence of plumage characters was performed. Reconstruction of ancestral character states revealed multiple events of independent evolution of derived character states in most characters studied, and a concentrated changes test revealed that some plumage characters evolved in association with habitat type. For example, there was a statistically significant association between loss of dorsal barring and use of densely vegetated habitats among Picoides species. Two analyses indicated that convergence, as opposed to parallel evolution or shared …

Determining The Optimum Beef Longissimus Muscle Size For Retail Consumers, K.K. Sweeter, D.M. Wulf, R.J. Maddock

Animal Science Faculty Publications

Research was conducted in two phases to determine the optimum beef LM size for retail consumers. In Phase I, 50 USDA Choice beef carcass sides were selected at a commercial packing plant and assigned to five different categories (10 sides per category) based on LM size: 61 to 68 cm2 (A), 70 to 78 cm2 (B), 80 to 90 cm2 (C), 92 to 103 cm2 (D), and 105 to 119 cm2 (E). Ribeye rolls were retrieved from all carcass sides. Steaks (2.5-cm thick; 14 per ribeye roll) were cut as needed and transported in groups of 35 steaks (seven per …

Chimpanzee Theory Of Mind: Looking In All The Wrong Places?, Kristin Andrews

Sentience Collection

I respond to an argument presented by Daniel Povinelli and Jennifer Vonk that the current generation of experiments on chimpanzee theory of mind cannot decide whether chimpanzees have the ability to reason about mental states. I argue that Povinelli and Vonk’s proposed experiment is subject to their own criticisms and that there should be a more radical shift away from experiments that ask subjects to predict behavior. Further, I argue that Povinelli and Vonk’s theoretical commitments should lead them to accept this new approach, and that experiments which offer subjects the opportunity to look for explanations for anomalous behavior should …

Cortical Complexity In Cetacean Brains, Patrick R. Hof, Rebecca Chanis, Lori Marino

Veterinary Science and Medicine Collection

Cetaceans (dolphins, whales, and porpoises) have a long, dramatically divergent evolutionary history compared with terrestrial mammals. Throughout their 55–60 million years of evolution, cetaceans acquired a compelling set of characteristics that include echolocation ability (in odontocetes), complex auditory and communicative capacities, and complex social organization. Moreover, although cetaceans have not shared a common ancestor with primates for over 90 million years, they possess a set of cognitive attributes that are strikingly convergent with those of many primates, including great apes and humans. In contrast, cetaceans have evolved a highly unusual combination of neurobiological features different from that of primates. As …

In Situ Examination Of Boldness–Shyness Traits In The Tropical Poeciliid, Brachyraphis Episcopi, Culum Brown, Felicity Jones, Victoria Braithwaite

Sentience Collection

Explaining consistent variation in the behaviour of individuals in terms of personality differences is one of the cornerstones of understanding human behaviour but is seldom discussed in behavioural ecology for fear of invoking anthropomorphism. Recently, however, interest has begun to focus on identifying personality traits in animals and examining their possible evolutionary consequences. One major axis used to define personality traits is the shyness–boldness continuum. We examined boldness in an in situ experiment using fish from eight populations of the poeciliid Brachyraphis episcopi (also referred to as Brachyrhaphis episcopi). Fish from high- and low-predation regions within four streams that run …

Evaluating Consumer Acceptability And Willingness To Pay For Various Beef Chuck Muscles, A.C. Kukowski, R.J. Maddock, D.M. Wulf, G.L. Taylor

Animal Science Faculty Publications

In-home consumer steak evaluations, followed by centralized laboratory-setting auctions, were used to determine consumer (n = 74 consumers) acceptability and willingness to pay for various beef chuck muscles. The infraspinatus (IF), serratus ventralis (SV), supraspinatus (SS), and triceps brachii (TB) from the beef chuck were evaluated against LM steaks from the rib to determine price and trait differentials. Muscles from USDA Choice, boneless, boxed-beef subprimals were aged 14 d, frozen, and cut into 2.5-cmthick steaks. Consumers received two steaks from each muscle for in-home evaluations of uncooked steak appearance and cooked steak palatability. After in-home evaluation of steaks, consumers participated …

Fisheries Occasional Publication No. 32 - Allocation Of The Western Australian Abalone Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to the Integrated Fisheries Allocation Advisory Committee (IFAAC), the Department will outline what it believes are the most practical and cost effective ways of managing a system for allocating the abalone resource between the commercial, customary and recreational sectors.

In preparing this submission, it has been noted that because of the limited data on recreational catch outside of the metropolitan area, the Sustainable Harvest Limit (SHL) set for the fishery relates only to the area that is equivalent to Area 7 of the commercial fishery. Further, it is acknowledged that the Minister has approved that proportional catch …

Efficacy Of Translocations For Restoring Populations Of Black-Tailed Prairie Dogs, Jo Ann L. D. Dullum, Kerry R. Foresman, Marc R. Matchett

United States Fish and Wildlife Service: Publications

We evaluated translocation as a method to promote recovery of black-tailed prairie dogs (Cynomys ludovicianus) after plague-induced population declines in colonies at the Charles M. Russell National Wildlife Refuge, Montana. We translocated prairie dogs in June of 1999 and evaluated the effects of translocation on colony area 1 year and 4 years later. We also assessed effects of release group size and estimated rates of population growth and survival. Initial size of experimental colonies was categorized as inactive (0 ha), small (0.1-2.0 ha), or large (2.0-6.6 ha); numbers of prairie dogs translocated to each colony size class were …

Molt Strategies And Age Differences In Migration Timing Among Autumn Landbird Migrants In Southwestern Idaho, Jay D. Carlisle, Gregory S. Kaltenecker, David L. Swanson

Intermountain Bird Observatory Publications and Presentations

Intraspecific patterns of autumn migration timing are not well known, particularly in the western United States. Here, we (1) describe autumn migration timing and age ratios of landbird migrants in southwestern Idaho, (2) examine differences in timing among age and sex classes, and (3) demonstrate how prebasic molt strategies affect migration timing differences between age classes. As a group, Neotropical migrants were most common from late July through early September, whereas temperate migrants were most common from mid-September into early October. Proportion of hatch-year birds was 74.5% for all migrants combined and ranged from 33.3% to 100% for individual species. …

Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum length of fishes captured with angling. Although significant (based on sequential Bonferroni adjustment) correlation was found in only one of nine sport fishes assessed, all correlations were positive indicating a general trend between maximum size of fishes captured with these …
