A Cladistic Analysis And Taxonomic Revision Of The Plesiosauria (Reptilia: Sauropterygia), F. Robin O’Keefe

Biological Sciences Faculty Research

The Plesiosauria (Reptilia: Sauropterygia) is a group of Mesozoic marine reptiles known from abundant material, with specimens described from all continents. The group originated very near the Triassic–Jurassic boundary and persisted to the end- Cretaceous mass extinction. This study describes the results of a specimen-based cladistic study of the Plesiosauria, based on examination of 34 taxa scored for 166 morphological characters. The Pliosauroidea is found to by polyphyletic due to the inclusion of the Polycotylidae; this second clade is instead a member of the Plesiosauroidea, and thus more closely related to elasmosaurs than to other ‘pliosaurs’. Characters of body proportion …

Fisheries Research Report No. 136 - Assessment Of Gonad Staging Systems And Other Methods Used In The Study Of The Reproductive Biology Of Narrow-Barred Spanish Mackerel, Scomberomorus Commerson, In Western Australia, Michael C. Mackie, Paul Lewis

Fisheries Research Reports

Recent research by the Department of Fisheries in Western Australia into the reproductive biology of narrow-barred Spanish mackerel has required the use of various field and laboratory techniques. This report documents the procedures and adaptations of some of these techniques. Assessment and development of illustrated, relevant macroscopic and microscopic staging systems were of particular focus because both have been essential components of the research. The simplified and more reliable macroscopic staging system we developed allowed full use of all gonad samples and a more complete (albeit less distinct) overview of the seasonal pattern of gonad reproductive development. This macroscopic staging …

Fisheries Research Report No. 130 - Environmental Requirements And Tolerances Of Rainbow Trout (Oncorhynchus Mykiss) And Brown Trout (Salmo Trutta) With Special Reference To Western Australia: A Review, Brett W. Molony

Fisheries Research Reports

Both Oncorhynchus mykiss (rainbow trout) and Salmo trutta (brown trout) have a long history of translocation and culture and a wide knowledge base exists. O.mykiss is being considered as a candidate for inland aquaculture in the salinity affected areas of southern Western Australia and this review aims, in part, at providing relevant information to those considering a trout-framing venture in Western Australia. Both species of trout can survive a wide range of environmental conditions, including temperature, salinity, pH, dissolved oxygen and ammonia, with O.mykiss having a higher temperature tolerance than S.trutta. However, within the ranges of environmental conditions, each species …

Development Of An Electrotransformation Technique For Streptococcus Iniae And Preliminary Characterization Of The Hemolysin Associated With This Bacterium, Kimberly Ann Hahn

Biological Sciences Theses & Dissertations

Streptococcus iniae is a gram-positive organism responsible for causing disease in both freshwater as well as saltwater fish. Every year fisheries lose fish by the tons due to diseases caused by this organism. In 1991, the first reported human case of disease associated with this organism was described. Since this initial case, there have been numerous other reported cases of S. iniae infections. This organism is a catalase negative, facultatively anaerobic organism that produces a capsule and when plated onto blood agar demonstrates β-hemolytic activity.

In this study, the relationship between the hemolysin produced by S. iniae and the lactate …

The Invasion Of Western Waters By Non-Native Species: Threats To The West, Western Regional Panel On Aquatic Nuisance Species

All U.S. Government Documents (Utah Regional Depository)

The waters of western North America are being transformed by invasive aquatic plants, fish, and other animals from around the world. These plants and animals, which have been introduced both intentionally and accidentally by humans, can irrevocably alter our native ecosystems. While they may be harmless in their own waters, once brought into a new ecosystem where their native predators do not exist, they can harm native species by eating their food, preying on them, transmitting diseases to which the natives have no defenses, or (like many invasive aquatic plants) simply outgrowing them. Not all non-native species cause serious problems, …

Fisheries Research Report No.128 - Aquaculture And Related Biological Attributes Of Abalone Species In Australia - A Review., Kylie A. Freeman

Fisheries Research Reports

China and Taiwan are the major producers of cultured abalone; with annual production estimated at 3,500 and 3,000 tonnes respectively. The world production of cultured abalone sold in 1999 was 7,775 tonnes. Australian farm production was still relatively low (89 tonne in 1999) but numerous abalone farms have been proposed and many have been constructed. On a national scale, Tasmania and South Australia are the major states involved in temperate abalone culture; however, new projects have commenced in Victoria and considerable interest exists in New South Wales. Pilot scale trials with tropical abalone aquaculture using the Donkey-ear abalone (Haliotis asinina) …

Fish Protection Measures To Ensure Fish For The Future, Jo Bunting

Fisheries Management Papers

The protection of Western Australia's aquatic animals, plants and habitats is important for many reasons. Fish, and many aquatic invertebrates, have significant commercial, recreational and social importance. Aquatic habitats provide food, refuge and breeding areas for fish and other animals. In addition, some habitats, such as rocky reefs and seagrass meadows, act as nursery sites for juvenile animals. Some habitats and their inhabitants (such as coral reefs) also have aesthetic values which support economically and socially important industries, such as tourism.

2001 Waterfowl Breeding Population Survey For South Dakota And North Dakota

United States Fish and Wildlife Service: Publications

The 2001 Waterfowl Breeding Ground and Habitat Survey for South and North Dakota was conducted 7 - 28 May with standard aerial coverage accomplished. Personnel changes occurred this year in both the air and ground crew. Habitat conditions were good to excellent through out most of the crew area. Compared to 2000 levels, wetland counts increased 58% in South Dakota and were similar (2%) in North Dakota. Waterfowl breeding populations were second and third highest of record for South Dakota (4.301 million) and North Dakota (5.767 million), respectively. The outlook for waterfowl production in 2001 is above average.

The Links Between Functionally Distinct Adult Assemblages Of Sardinops Sagax : Larval Advection Across Management Boundaries, Daniel J. Gaughan, K V. White, Warrick (Rick) J. Fletcher

Fisheries Research Articles

Otolith increment data were used to age larval Sardinops sagax collected from shelf waters between Kangaroo Island in South Australia (SA) and Albany in Western Australia (WA). Distributions of both ages and hatch-dates were compared between six regions across this broad area to examine the hypothesis that larvae arising from spawning sardines in WA may be advected by the Leeuwin Current to the central coast of SA prior to metamorphosis. Current and wind data were analysed to estimate potential rates of passive transport. It appears likely that larvae arising from commercially exploited S. sagax populations in WA can be passively …

For The Birds

United States Fish and Wildlife Service: Publications

As you learn to enjoy the beauty of birdlife around their home, you may wish to improve the “habitat” in your yard so that more birds will visit your property. You can attract birds by placing bird feeders, nest boxes, and bird baths in your yard, and by planting a variety of trees, shrubs, and flowers. These can provide good nesting sites, winter shelter, places to hide from predators and natural food supplies that are available year-round.

Backyard bird feeding is a convenient way to enjoy wildlife. More than 65 million Americans of all ages watch, feed and landscape for …

In Support Of A Rationally Managed Fishery: Age And Growth In Patagonian Toothfish (Dissostichus Eleginoides), Julian R. Ashford

Biological Sciences Theses & Dissertations

Patagonian toothfish (Dissostichus eleginoides) occur on the continental shelves and shelf breaks of southern South America and the Southern Ocean. Stock structure, critical to good fisheries management, can be inferred from growth differences between areas, but available growth data are compromised by inconsistencies in age estimation methods, sampling and sample sizes, and techniques used to derive estimates. I asked the scientific question: how is growth in Patagonian toothfish structured spatially within the Southern Ocean? I developed a multi-stage randomized design to sample fish caught by commercial longline, and an age estimation methodology. Because toothfish are difficult to age, …

Fisheries Research Report No. 125 - A History Of Foreign Fishing Activities And Fishery-Independent Surveys Of The Demersal Finfish Resources In The Kimberley Region Of Western Australia, G Nowara, Stephen J. Newman

Fisheries Research Reports

The aim of this project was to collate all historical information regarding fishing activities relevant to the Northern Demersal Scalefish Fishery. Three primary sources of information were identified; foreign Taiwanese pair-trawl fishing activities; traditional Indonesian fishing activities; and fishery-independent (CSIRO) survey data.

The Taiwanese pair-trawl fishing catch and effort from 1980 to 1990 was concentrated into two main regions, the Broome area (120°-122°E) and the Holothuria Banks area (124°-126°E) in the north. The majority of trawls were undertaken in the mid-continental shelf region (60-100 m). The total catch of these vessels reached a peak of 4,394 tonnes in 1985. Effort …

Distribution, Morphometries, And Tooth Morphology Of The Genus Desmognathus In West Virginia, Jessica Ann Wooten

Theses, Dissertations and Capstones

Very few genera of vertebrates demonstrate variation in body size, color, pattern, and life history traits to the extreme that is demonstrated in the genus Desmognathus. Exact distribution of Desmognathus, as well as other genera of salamanders, is very difficult to outline because of hybridization between certain desmognathine species. Tooth morphology, tail keeling, head and body shape, and geographic location are factors used in the separation among species in this genus. There are five desmognathine salamanders, including D. monticola, D. fuscus, D. ochrophaeus, D. quadramaculatus, and 0. welteri in West Virginia. The purpose of this study was to analyze the …

A Natural History Study Of Desmognathus Welteri In West Virginia, Zachary Ira Felix

Theses, Dissertations and Capstones

The Black Mountain salamander, Desmognathus welteri, is a relatively large brownish-green salamander that possesses morphological characters associated with a semi-aquatic lifestyle. The history of this species in the state of West Virginia is an interesting one. Due to taxonomic confusion and the lack of a thorough investigation of the species in the state, little was known about the species until recently. Surveys for Desmognathus welteri in southern West Virginia revealed five new populations. This makes 17 localities for the species in the state. It appears D. welteri is restricted to relatively high elevation, high gradient, forested streams in the Cumberland …
