Status Of Demersal Finfish Stocks On The West Coast Of Australia, David V. Fairclough, Brett W. Molony, Brett M. Crisafulli, Ian S. Keay, Sybrand Alexander Hesp, Ross J. Marriott

Fisheries Research Reports

Assessments of the key indicator species for the West Coast Demersal Scalefish Resource (WCDSR; West Australian dhufish Glaucosoma hebraicum, Snapper Pagrus auratus and Baldchin groper Choerodon rubescens) in 2007 and 2009 demonstrated that the stocks were experiencing overfishing. Thus, between late 2007 and early 2010, substantial changes were made to the management of the commercial and recreational fisheries that exploit the WCDSR. These were designed to reduce catches of the entire suite of demersal scalefish species (and of each indicator species) by both the commercial and recreational sectors in the West Coast Bioregion (WCB) by at least 50 % of …

The Ipocamp Pressure Incubator For Deep-Sea Fauna, Bruce Shillito, Françoise Gaill, Juliette Ravaux

Journal of Marine Science and Technology–Taiwan

Animal Biology studies have always benefited from the achievement of experiments on live animals, which obviously provide data on dynamic aspects of physiology. When it comes to deep-sea fauna, in vivo experiments are impaired, and in some cases impossible, due to the severe and often lethal stress experienced by animals throughout the sampling process. However, freshly collected deep fauna may be maintained alive and in good condition, by using specific aquaria which restore environmental conditions prevailing at depth in situ. Here we describe the pressure device named “Incubateur Pressurisé pour l’Observation et la Culture d’Animaux Marins Profonds”, or IPOCAMP, and …

Ecomorphology And Mating Behavior Of Two Species Of Night-Stalking Tiger Beetles, Omus Audouini And O. Dejeanii, Robert Kent Richardson

Dissertations and Theses

Night-stalking tiger beetles (Cicindelinae: Omus) are among the least studied members of the highly diverse Carabid sub-family Cicindelinae, the tiger beetles. Despite populations of Omus being common in the forest floor habitats of the west coast of North America and their conspicuous predatory role within terrestrial arthropod communities, little is known about the biology and ecology of Omus.

Field studies showed that two species of Omus existed in the forested areas of Powell Butte Nature Park, Portland, Oregon, USA: Omus audouiniand O. dejeanii. The co-occurrence of sympatric, and likely syntopic, species allowed for a comparative approach in examining and analyzing …

A Study Of The Niche Structure And Habitat Utilization Of Urban Dwelling Winter Birds, Thomas Huff

Honors Theses

A study was conducted to evaluate the distribution of urban birds relative to differences in habitat as determined by zoning type. A total of 1,948 individual birds and a total of 33 species were sampled across the four different zones (industrial, commercial, residential, and public use.) The industrial use zone contained the highest number of individuals whereas commercial zones contained the fewest. However, the four zones contained approximately equal species richness.

Industrial zones supported the greatest number of cavity nesting and seed eating species. Residential and public use zones contained greater numbers of insectivorous and cup nesting species. In the …

Ecology Of Glacial Relict Fishes In South Dakota's Sandhills Region, Eli Felts

Electronic Theses and Dissertations

Native stream fish zoogeography has changed substantially across North America during the last century as habitat degradation, stream fragmentation and introductions of nonnative species have led to numerous extinctions, extirpations and altered distributions. Insufficient information regarding imperiled species often results in reactive, rather than proactive, management, and knowledge of species status and ecology is critical in identifying conservation priorities. South Dakota populations of three dace species (northern redbelly dace Chrosomus eos, finescale dace Chrosomus neogaeus, and pearl dace Margariscus margarita) are relict of Pleistocene Glaciation and are isolated from the northern core of their distribution, but little information exists regarding …

Chemical Defense Of An Asian Snake Reflects Local Availability Of Toxic Prey And Hatchling Diet, D. A. Hutchinson, A. H. Savitzky, G. M. Burghardt, C. Nguyen, J. Meinwald, F. C. Schroeder, A. Mori

Biological Sciences Faculty Publications

Species that sequester toxins from prey for their own defense against predators may exhibit population-level variation in their chemical arsenal that reflects the availability of chemically defended prey in their habitat. Rhabdophis tigrinus is an Asian snake that possesses defensive glands in the skin of its neck (nuchal glands'), which typically contain toxic bufadienolide steroids that the snakes sequester from consumed toads. In this study, we compared the chemistry of the nuchal gland fluid of R.tigrinus from toad-rich and toad-free islands in Japan and determined the effect of diet on the nuchal gland constituents. Our findings demonstrate that captive-hatched juveniles …

Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Lesser scaup (Aythya affinis [Eyton]) populations remain below their long-term average despite improved habitat conditions along spring migration routes and at breeding grounds. Scaup are typically associated with large, semipermanent wetlands and exhibit regional preferences along migration routes. Identifying consistently used habitats for conservation and restoration is complicated by irregular wetland availability due to the dynamic climate. We modeled long-term wetland use by lesser scaup in eastern South Dakota based on surveys conducted during below-average (1987-1989) and above-average (1993-2002) water condition years. Wetland permanence, longitude, and physiographic region were all significant determinants of use (P < 0.01). Long-term use was best described by a quadratic equation including wetland surface area variability, an index of wetland hydrodynamics that is linked to productivity, biodiversity, and value to waterfowl. Contrary to previous findings, our study shows that over the long term, lesser scaup are more than twice as likely to use permanent wetlands as they are semipermanent wetlands. The northern region of South Dakota's Prairie Coteau, which holds the highest density of hydrologically dynamic permanent wetlands, should be considered an area of conservation concern for lesser scaup. The criteria we identified may be used to identify important lesser scaup habitats in other regions of the Prairie Pothole Region.

Isospora Species (I. Canaria, Isospora Sp.) In Canaries (Serinus Canarius, Linnaeus), Cem Ecmel Şaki̇, Edi̇p Özer

Turkish Journal of Veterinary & Animal Sciences

Of 64 canaries with diarrhea in Elazığ Province between May 2002 and May 2006, 18 (28.1%) had Isospora oocysts in their feces. It was determined that the oocysts, examined morphologically before and after sporulating, were Isospora canaria and Isospora sp. Among the infected animals, 8 (44.4%) were concurrently infected with both species. Total numbers of I. canaria oocysts were greater than those of Isospora sp. A total of 2 canaries showing severe clinical signs were necropsied. Liver, spleen, and lung preparations and peripheral blood smears of the necropsied animals were examined for Atoxoplasma, and no development forms were seen. For …

Microtaxonomy Of Fragmenting Enchytraeus Species Using Molecular Markers, With A Comment On Species Complexes In Enchytraeids, Rut Collado, Eva Hass-Cordes, Ruediger Schmelz

Turkish Journal of Zoology

Populations of Enchytraeus that reproduce by fragmentation are distributed worldwide, but their species-level taxonomy is unresolved because morphological differences are inconclusive. Therefore, we compared the isozyme and RAPD-PCR patterns of 5 populations of fragmenting enchytraeids from widely distant localities (Japan, Iran, Greece, and Brazil). Among these populations, 3 were identified (E. japonensis, E. bigeminus, and E. dudichi) and 2 were unidentified. Multiple isozyme bands suggested polyploidy in all investigated populations. In all RAPD-PCR algorithms except 1, the fragmenting group formed a cluster separate from 2 nonfragmenting Enchytraeus species. All 5 populations were clearly separable on the levels of protein and …

Parasitic Hymenoptera Reared From The Insects On Heracleum Platytaenium Boiss. (Apiaceae) With New Faunistic And Biological Records, Erhan Koçak, Mustafa Özdemi̇r

Turkish Journal of Zoology

Some parasitic hymenopterans were reared from their host insects found on the stems and branches of Heracleum platytaenium Boiss., which contains furanocoumarins that are insect repellents and suppress growth in some species. Plant materials with insects were collected from the vicinity of Kızılcahamam in Ankara Province in July-September 2008. The parasitoids (Hymenoptera) and their hosts were Didyctium brunnea (Belizin) (Eucolidae) from puparia of Lasiambia albidipennis (Strobl) (Diptera: Chloropidae), Pronotalia carlinarum (Szelenyi & Erdos) (Eulophidae) and Homoporus febriculosus (Girault) (Pteromalidae) from puparia of Melanagromyza heracleana Zlobin (Diptera: Agromyzidae), and Baryscapus crassicornis (Erdos) (Eulophidae) from larvae, pupae, and adults of Lixus nordmanni …

Further Considerations On The Species Of The Genus Orthochirus Karsch, 1891 From Africa, With Description Of Three New Species (Scorpiones: Buthidae), Wilson R. Lourenço, Elise-Anne Leguin

Euscorpius

New considerations are proposed regarding the African species of the genus Orthochirus Karsch, 1891. Two species, Orthochirus aristidis (Simon, 1882) and Orthochirus innesi Simon, 1910 have been the subject of several publications in the past decades; however, doubts remain about their exact identity and range of geographical distribution. In this note, their taxonomic status is reinvestigated. The type material is revised and the lectotype and paralectotypes are designated for O. aristidis. Revised diagnoses and illustrations are proposed for both species, and these are confirmed as valid. Three new species are described from Algeria, Morocco, and Mauritania. The total number …

An Alignment Approach To Identify Fish With Encoding Hydroacoustic Signal To Acoustics Alphabet Squences, Shih-Yen Ku, Hsueh-Jung Lu, Chi-Ting Tseng, Ker-Chau Li, Long-Jin Wu

Journal of Marine Science and Technology–Taiwan

1D sequence homologous alignment tool, like FastA (FASTALL) [8] or BLAST (Basic Local Alignment Search Tool) [1], has been widely used in bioinformatics field and perform elegant and fast searching for the sequences developed from the same kinds of species. In other word, it can classify through determining the homologous similarity which is not totally similar in sequences of protein sequences, structure or nucleotide sequences. An approach is proposed in this paper called AA-FAST (abbreviation for Acoustics Alphabet-FAST) which takes advantage of alignment tool and significant sequence encoding method. In this experiment, it could not only determine 4 fish species …

Using Archaeological Fish Remains To Determine The Native Status Of Anadromous Salmonids In The Upper Klamath Basin (Oregon, Usa) Through Mtdna And Geochemical Analysis, Alexander E. Stevenson

Dissertations and Theses

Within the Upper Klamath Basin, Oregon, the native status of anadromous salmonids (Oncorhynchus spp.) has been a long standing question. Ongoing efforts to establish if these fish were native to the region prior to the construction of the Copco I Dam on the Klamath River (c.1917) have relied on sparse, contradictory and sometimes unreliable historic documentation and informant testimony. Current restoration projects with very high financial and social costs necessitate accurate and reliable data on salmonid species which once called the region home. Often, archaeolofaunal remains present a novel way to determine species present in an area prior to …

Review Of The Exploitation Of Marine Resources Of The Australian Indian Ocean Territories: The Implications Of Biogeographic Isolation For Tropical Island Fisheries, Matthew Hourston

Fisheries Research Reports

The small islands of the Indian Ocean Territories are isolated reefs in an expanse of open ocean of abyssal depth. The majority of marine species that live on their reefs and lagoons have settled there from remote locations. Colonising individuals are presumed to have come to the island as the result of unusual weather and current conditions and form populations that are, necessarily, largely self-sustaining. The isolated populations that make up many of the fish and invertebrate stocks at the Cocos (Keeling) and Christmas Islands rely almost exclusively on larvae returning to their home reef to settle, grow and ultimately …

In Vitro Enabling Technologies For Use In The Aquatic Environment, Colm J. O'Dowd

Shark Bay Prawn And Scallop Fisheries: Final Review Report, Western Australia. Department Of Fisheries

Fisheries Management Papers

The Shark Bay Prawn Fishery and Shark Bay Scallop Fishery operate in the same general areas of Shark Bay (although there are some differences in their areas of operation). The interrelationship between trawling activities for the two target species (prawns and scallops) has raised both management challenges and industry conflicts over time. Harvest level settings for each fishery (in the form of effort levels and the timing and/or location of fishing) are independently set, on the basis of recruitment and abundance surveys of each target species. However, each industry sector strongly believes that the interactions between the fisheries arise because …

The Identification Of Rana Ocellata Linnaeus, 1758. Nomenclatural Impact On The Species Currently Known As Leptodactylus Ocellatus (Leptodactylidae) And Osteopilus Brunneus (Gosse, 1851) (Hylidae), Esteban O. Lavilla, José A. Langone, Ulisses Caramaschi, W. Ronald Heyer, Rafael O. De Sá

Biology Faculty Publications

The usage of the name Rana ocellata Linnaeus, 1758, is plagued by misidentifications and misinterpretations. After an exhaustive bibliographic review, we conclude that the Linnaeus 1758 name refers to Osteopilus brunneus (Gosse, 1851) from Jamaica, while the taxon currently known as Leptodactylus ocellatus corresponds to Rana latrans Steffen, 1815. Herein, we designate and provide descriptions of the neotypes of Leptodactylus latrans (Steffen, 1815), revalidated, new combination, and Osteopilus ocellatus (Linnaeus, 1758), new combination, as a senior synonym of Osteopilus brunneus (Gosse, 1851).
