Characterization Of Biological Types Of Cattle (Cycle Viii): Carcass, Yield, And Longissimus Palatability Traits, T. L. Wheeler, L. V. Cundiff, S. D. Shackelford, M. Koohmaraie

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The objective of this experiment was to evaluate alternative sources of tropically adapted cattle germplasm and compare them with Angus- (AN) and Hereford- (HE) sired steers. Carcass, yield, and longissimus thoracis palatability traits from F₁ steers (n = 621) obtained from mating AN and United States Meat Animal Research Center III cows to HE, AN, Brangus (BR), Beefmaster (BM), Bonsmara (BO), or Romosinuano (RO) sires were compared. Data were adjusted to constant age (426 d), carcass weight (340 kg), fat thickness (1.0 cm), fat trim percentage (25%), and marbling (Small⁰⁰) endpoints. For Warner- Bratzler and slice …

Potential Reallocation Mechanisms For The Transfer/And Or Adjustment Of Catch Shares Of Sectors With Application To The Western And South Australian Rock Lobster Fisheries. A Discussion Paper., Chris Reid

Fisheries Management Papers

To allow for a greater understanding of potential allocation adjustment mechanisms and requirements for their implementation, Western Australia’s Department of Fisheries is exploring potential mechanisms with reference to their application in the Western and South Australian rock lobster fisheries. This work is being conducted as part of the Fisheries Research and Development Corporation (FRDC) project 2007/050 Developing Mechanisms for the Transfer and/or Adjustment of Rock Lobster Shares Between Sectors in Western Australia and South Australia. This report documents the Department of Fisheries’ initial exploration and findings in relation to potential inter-sectoral reallocation mechanisms.

Considerations For The Implementation Of Western Rock Lobster Sectoral Allocations., Integrated Fisheries Allocation Advisory Committee

Fisheries Management Papers

This paper discusses the Western rock lobster allocation process.

The Minister for Fisheries has determined that the allocation for sectors in the western rock lobster fishery after reserving one tonne for the customary sector shall be 95 per cent commercial and five per cent recreational.

The notional Sustainable Harvest Level (SHL) for rock lobster is expressed as a range, depending on the status of the stock rather than a specific quantitative limit.

North America’S Ducks, Geese And Swans In The 21st Century: A 2010 Supplement To Waterfowl Of North America, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010) by Paul A. Johnsgard

Since the 1975 publication of Waterfowl of North America, a great deal of ornithological literature has appeared concerning North American ducks, geese & swans. The most significant of these are the species accounts in the American Ornithologists’ Union The Birds of North America (B.O.N.A.) series, 46 of which were published between 1993 and 2003, and which include all the species known to breed in the United States and Canada (see references).

Population data of wild species are constantly changing, and sometimes of limited accuracy, but long-term averages or trends are often significant. National population surveys such as the annual U.S. …

Waterfowl Of North America: Whistling Ducks, Tribe Dendrocygnini, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010) by Paul A. Johnsgard

Whistling ducks comprise a group of nine species that are primarily of tropical and subtropical distribution. In common with the swans and true geese (which with them comprise the subfamily Anserinae), the included species have a reticulated tarsal surface pattern, lack sexual dimorphism in plumage, produce vocalizations that are similar or identical in both sexes, form relatively permanent pair bonds, and lack complex pair-forming behavior patterns. Unlike the geese and swans, whistling ducks have clear, often melodious whistling voices that are the basis for their group name. The alternative name, tree ducks, is far less appropriate, since few of the …

Ducks, Geese, And Swans Of The World: Tribe Anseranatini (Magpie Goose), Paul A. Johnsgard

Ducks, Geese, and Swans of the World by Paul A. Johnsgard

Other vernacular names. Semipalmated goose, pied goose, black-and-white goose; Spaltfussgans (German); oie pie (French); gans overo o pintado (Spanish).

This is the only species of true waterfowl with only partially webbed feet. Adults of both sexes are black on the head, neck, wings, rump, and tail, and white elsewhere. The bill is long and straight, with a well-developed nail at the tip; as in swans, the head is featherless back to the eyes. Females resemble males but are somewhat smaller, lack an enlarged bony crown, and have a higher-pitched voice. Adult males have an elongated trachea that loops downward between …

Ducks, Geese, and Swans of the World by Paul A. Johnsgard

Inasmuch as the primary purpose of this book is to provide information on each of the species of the waterfowl family in a standardized format and easily accessible manner, it is important that the reader have some knowledge of the basis for my sequential organization of these species. A variety of attempts to provide a "natural" classification, or one that best reflects actual evolutionary relationships, of the family Anatidae have been made in recent years, with most of them being minor variations on a scheme first proposed by Jean Delacour and Ernst Mayr in 1945. In this landmark classification, emphasis …

Ducks, Geese, And Swans Of The World: Tribe Stictonettini (Freckled Duck), Paul A. Johnsgard

Ducks, Geese, and Swans of the World by Paul A. Johnsgard

Freckled Duck
Even more than the Cape Barren goose, the freckled duck exhibits an assortment of anatomical traits that suggest affinities with the geese and swans, in spite of a fairly typical ducklike appearance and foraging behavior. Its unpatterned downy young, its remarkably primitive syringeal structure, and its reticulated tarsus all strongly argue for the position that this species is the sole survivor of a very ancient waterfowl lineage, with no near living relatives. A detailed study of its social behavior is greatly to be desired, for like the magpie goose, it provides an unequaled opportunity to gain insight into …

Flying Steamer Duck
Magellanic Flightless Steamer Duck
Falkland Flightless Steamer Duck

The South American steamer ducks have at times been included with the shelducks, but differ enough from them in structure and behavior to be regarded as a separate but closely related tribe. There are three species very similar in appearance; two are essentially flightless. All are found off the coasts of southern South America and the Falkland Islands, where they feed on mollusks and other marine invertebrates. The males differ slightly from females in their plumage and vocalizations, but in both sexes iridescent coloration is totally lacking and only …

The stiff-tailed ducks are characterized by several unusual features in addition to their long, stiffened tail feathers that serve as underwater rudders. Among other adaptations are their very large feet, which are placed so far back on the body that it is difficult for these birds to walk on land. The body feathers are small, numerous, and have a grebe-like sheen, and the wings are so short that takeoff and flight is attained with difficulty. All of the species have relatively short …

Waterfowl Of North America: Swans And True Geese, Tribe Anserini, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010) by Paul A. Johnsgard

The approximately twenty extant species of swans and true geese are, unlike the whistling ducks, primarily of temperate and arctic distribution, especially in the Northern Hemisphere. It is thus not surprising that continental North America may lay claim to at least nine breeding species, or nearly half.of the known total. Additionally, sufficient records of a tenth, the barnacle goose, are known as to warrant its inclusion in the book even though there is no indication that it nests in continental North America. Several additional Old World species of geese and swans have been reported one or more times in North …

Waterfowl Of North America: Surface-Feeding Ducks, Tribe Anatini, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010) by Paul A. Johnsgard

The surface-feeding, dabbling, or similarly described ducks are a group of about thirty-six species of mostly freshwater ducks that occur throughout the world. Many of them are temperate or arctic-breeding species that nest on dry land near freshwater ponds, marshes, rivers, or similar rather shallow bodies of water. Associated with this breeding habitat are their adaptations for foraging by "tipping-up" rather than by diving for food, an ability to land and take off abruptly from small water areas or land, and a moderately good walking ability but reduced perching capabilities as compared with perching ducks. Also unlike perching ducks, iridescent …

The Occurrence Of Epizoic Ciliates (Protozoa: Ciliophora) Of The Juvenile Flounder, Platichthys Flesus L., 1758, From Sarıkum Lagoon Lake (Sinop, Turkey), Türkay Öztürk, Ahmet Özer

Turkish Journal of Zoology

The occurrence of epizoic ciliates on the juvenile flounder, Platichthys flesus L., 1758, collected monthly by fishing net in Sinop's Sarıkum Lagoon Lake during the period from May 2003 to April 2004, was investigated. Five epizoic ciliate species, Trichodina jadranica (Raabe, 1958) Haider, 1964; Trichodina domerguei Wallengren, 1897; Riboscyphidia sp.; Ambiphrya sp.; and Vorticella sp., were found after examination of 296 juvenile flounder. Among these, T. jadranica was the dominant species. The prevalence and mean intensity values of the 5 epizoic ciliates were given as pooled data for 2 groups, namely mobiline ciliates and sessiline ciliates. Mobiline ciliates were commonly …

Status And Distribution Of The Gapped Ringed Crayfish, Orconectes Neglectus Chaenodactylus, In Arkansas, Brian K. Wagner, C. A. Taylor, Mark D. Kottmyer

Journal of the Arkansas Academy of Science

Orconectes neglectus chaenodactylus, the gapped ringed crayfish, is an uncommon and poorly-known, stream-dwelling crayfish that is endemic to the central White River basin of Arkansas and Missouri. This study surveyed a semi-random selection of stream sites in the Arkansas portion of this range in order to characterize the crayfish communities and evaluate the status of O. n. chaenodactylus in Arkansas. Collections of a total of 1,107 individual crayfish specimens were made at 45 sites, including 497 O. n. chaenodactylus from 21 sites. Orconectes punctimanus was the crayfish species most commonly associated with O. n. chaenodactylus, occurring at 71% of sites …

Population Status Of The Southern Cavefish, Typhlichthys Subterraneus In Arkansas, A. Romero, M. S. Connor, G. L. Vaughan

Journal of the Arkansas Academy of Science

We summarize the results of our study on the status of the southern cavefish (Typhlichthys subterraneus) in Arkansas. Its presence in the state represents the western-southern limits of its distribution. Four localities have been confirmed that contain individuals of this species: Richardson Cave (Fulton County), Alexander Cave/Clark Spring (Stone County), Ennis Cave (Stone County), and Lake Norfork (Baxter County). A fifth locality has been cited as a well in Randolph County, but because the exact location is unknown, its presence has not been confirmed. A number of unconfirmed localities for “cavefishes” in the region has not been included in this …

Latitudinal Variation In Seasonal Activity And Mortality In Ratsnakes (Elaphe Obsoleta), Jinelle H. Sperry, Gabriel Blouin-Demers, Gerardo L.F. Carfagno, Patrick J. Weatherhead

Biology Faculty Publications

The ecology of ectotherms should be particularly affected by latitude because so much of their biology is temperature dependent. Current latitudinal patterns should also be informative about how ectotherms will have to modify their behavior in response to climate change. We used data from a total of 175 adult black ratsnakes (Elaphe obsoleta) radio tracked in Ontario, Illinois, and Texas, a latitudinal distance of > 1500 km, to test predictions about how seasonal patterns of activity and mortality should vary with latitude. Despite pronounced differences in temperatures among study locations, and despite ratsnakes in Texas not hibernating and switching from diurnal …

Broad-Scale Relations Between Conservation Reserve Program And Grassland Birds: Do Cover Type, Configuration And Contract Age Matter?, Sam Riffell, Daniel Scognamillo, L. Wes Burger Jr., Shawn Bucholtz

Faculty Publications

The Conservation Reserve Program (CRP) is a voluntary cropland set-aside program where environmentally-sensitive cropland is retired to a conservation practice. Grassland birds should benefit because most CRP is grass habitat and because amount of land in CRP is highest in agriculture-dominated areas of the United States where grassland habitat has been most impacted. We used the Breeding Bird Survey and Common Land Unit (CLU) data (spatially-explicit data of farm field boundaries and land cover) to identify relations between types and configurations of CRP and grassland bird abundance in 3 Midwestern states. All 13 species we studied were related to at …

The Role Of Retrieval And Translocation In A Reintroduced Population Of Migratory Whooping Cranes, Sara E. Zimorski, Richard P. Urbanek

Proceedings of the North American Crane Workshop

Beginning in 2001, a reintroduction project was initiated using captive-reared whooping cranes (Grus americana) to establish a migratory flock in eastern North America. From May 2003 to August 2008, 23 of these birds were retrieved and translocated in 15 separate events. These individuals consisted of 14 cranes that had been led to Florida by ultralight aircraft on their first autumn migration (UL) and 9 cranes that had been directly released in autumn in Wisconsin (DAR). Of 104 (86 UL and 18 DAR) reintroduced individuals that eventually departed from their release location, 22% were later retrieved 1-3 times. Lake …

Home Range Size And Habitat Use Of Mississippi Sandhill Crane Colts, Scott G. Hereford, Tracy E. Grazia, Jereme N. Phillips, Glenn H. Olsen

Proceedings of the North American Crane Workshop

Recruitment in the endangered Mississippi sandhill crane (Grus canadensis pulla) is minimal, with the population of 110 sustained by an annual augmentation of captive-reared juveniles. Suitability of available habitat quality is likely involved in nesting success. Thousands of hectares of pine savanna were restored for crane use, but it is not clear how much was being used by crane families. We used 3-g subcutaneous transmitters to radio-tag 27 colts over 6 years from 1998 to 2002 and 2004 to determine home range and habitat use. Using a hand-held receiver, H-antenna and standard triangulation, location data were collected twice …
