An Assessment Of Factors Affecting Population Growth Of The Mountain Plover, Stephen J. Dinsmore, Michael B. Wunder, Victoria J. Dreitz, Fritz L. Knopf

Wildlife Biology Faculty Publications

Effective conservation measures should target the most sensitive life history attributes of a species, assuming they are responsive to potential management actions. The Mountain Plover (Charadrius montanus) is a species of conservation concern with a patchy breeding distribution in western North America. Plovers prefer areas with short vegetation, bare ground, and disturbance for nesting. Current management tools, including grazing and burning, have been used to attract plovers and enhance nesting success. We used a stage-specific matrix model to study the influence of vital rates, e.g., juvenile and adult annual survival, on population growth rate in the Mountain Plover …

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 …

This group of 13 species of primarily perching waterfowl is a rather heterogeneous assemblage of birds that are not easily characterized. In addition to being generally perching and cavity-nesting, they also have fairly wide, rounded wings, elongated tails, and sometimes also relatively long legs. Many of the species exhibit a great deal of iridescent coloration in their plumage, even among females, and in a few species nearly …

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 …

Basis Of Host Plant Recognition And Acceptance By Busseola Fusca (Fuller) (Lepidoptera: Noctuidae) Larvae, Gerald Juma

All PhD Dissertations

Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is an important pest of maize and sorghum in sub-Saharan Africa whose larvae exhibits oligophagic than polyphagic feeding habits. The host plants for this species are primarily maize and sorghum though some populations appear to be restricted on wild sorghum. The purpose of this study was to determine the extent of oligophagy of larvae of this species based on (i) the sensory abilities to discriminate among different host plants (ii) feeding behaviour and growth on different Poaceae plant species present in its natural habitat (iii) plant stimuli that influence larval growth and feeding and (iv) …

Developing Emotional Security Among Children Who Have Been Adopted, Kate Trujillo

Electronic Theses and Dissertations

This study investigated the development of emotional security among 6-10 year old children who have been adopted by exposing them to an experimental condition during which they could engage with either a live dog or a robotic dog. The live dog was a certified therapy dog; the robotic dog was a FurReal® toy marketed by Hasbro as "Biscuit." Utilizing a mixed-method embedded experimental design, the experimental condition was intentionally structured to promote engagement between the participant and the dog or robot. 43 children who had been adopted from the child welfare system were randomly assigned to one of two groups. …

Turnover Of Mature Mirnas And Sirnas In Plants And Algae, Heriberto Cerutti, Fadia Ibrahim

Center for Plant Science Innovation: Faculty Publications

rnicroRNAs (miRNAs) and small interfering RNAs (siRNAs) play important roles in gene regulation and defense responses against transposons and viruses in eukaryotes. These small RNAs generally trigger the silencing of cognate sequences through a variety of mechanisms, including RNA degradation, translational inhibition, and transcriptional repression. In the past few years, the synthesis and the mode of action of miRNAs and siRNAs have attracted great attention. However, relatively little is known about mechanisms of quality control during small RNA biogenesis as well as those that regulate mature small RNA stability. Recent studies in Arabidopsis thaliana and Caenorhahditis elegans have implicated 3′-to-5′ …

Factory Farming: The Truth About The Poultry Industry, Jessica Stopa

e-Vision Journal of Undergraduate Writing

The farms of wide-open pastures, free-ranging cows, and chicken pens are becoming a thing of the past. Today, the farm industry is turning into a factory--a completely industrialized machine. Animals that are raised for food are seen solely as a way to earn profit. Animals are now treated as goods, mere means to the producers, and are no longer seen as living organisms that are helping people survive.

Jessica Stopa is from Sterling, Virginia. She is an English major and a Secondary Education minor and hopes to one day to be a high school English teacher. She is a member …

Γ-Zeins Are Essential For Endosperm Modification In Quality Protein Maize, Yongrui Wu, David R. Holding, Joachim Messing

Center for Plant Science Innovation: Faculty Publications

Essential amino acids like lysine and tryptophan are deficient in corn meal because of the abundance of zein storage proteins that lack these amino acids. A naturalmutant, opaque 2 (o2) causes reduction of zeins,anincreaseofnonzeinproteins,andas a consequence, adoubling of lysine levels.However, o2’s soft inferior kernels precluded its commercial use. Breeders subsequently overcame kernel softness, selectingseveral quantitative loci (QTLs), called o2modifiers,without losing the high-lysine trait. These maize lines are known as “quality protein maize” (QPM). One of the QTLs is linked to the 27-kDa γ-zein locus on chromosome 7S. Moreover, QPM lines have 2- to 3-fold higher levels of the 27-kDa γ-zein, …
