Phosphorus For High Rainfall Pastures, Mike Bolland, Bill Russell, David Weaver 2010 Agriculture Western Australia

Phosphorus For High Rainfall Pastures, Mike Bolland, Bill Russell, David Weaver

Bulletins 4000 -

Soil testing for phosphorus provides a reliable indication of when the level of phosphorus in a soil is likely to be adequate for pasture production in the next growing season. It is a waste of money to apply phosphorus fertiliser when soil testing indicates none is required, or to acidified soils, or to undergrazed pastures, or to pastures dominated by poorly productive species.

Legumes have higher phosphorus requirement than grasses.

Critical soil test phosphorus values do not change when nitrogen fertiliser is applied.


Production Of Premium Waxflowers, Kevin Seaton, Nikki Poulish 2010 Department of Primary Industries and Regional Development, Western Australia

Production Of Premium Waxflowers, Kevin Seaton, Nikki Poulish

Bulletins 4000 -

The cut flower trade is a highly competitive global market. Waxflowers are grown around the world—often in countries with lower cost structures or closer proximity to our main markets. Western Australian producers can only compete if their product stands out from the crowd in terms of quality, presentation and uniqueness, however, it still has to represent good value for money.


Micro-Environment And Plant Assemblage Structure On Virginia's Barrier Island "Pimple" Dunes, Brett A. McMillan, Frank P. Day 2010 Old Dominion University

Micro-Environment And Plant Assemblage Structure On Virginia's Barrier Island "Pimple" Dunes, Brett A. Mcmillan, Frank P. Day

Biological Sciences Faculty Publications

“Pimple” dunes are small, rounded coastal dunes that form along major dune ridges of the barrier islands along the Eastern Shore of Virginia. Although most pimple dunes are small structures ranging between 10 and 20 m in diameter, they have distinct plant assemblages that replicate the upland ecotones of their barrier islands. We examined the relationship between microenvironment, edaphic factors, and plant assemblage structure on pimple dunes. Water availability was an obvious major ecological driver, but we also tested other environmental factors that may correlate with plant assemblage structure. We found distinct assemblage types that segregated themselves by habitat type: …

Spawning-Related Movements Of Barred Sand Bass Paralabrax Nebulifer, In Southern California: Interpretations From Two Decades Of Historical Tag And Recapture Data, E. T. Jarvis, Christi Linardich, C. F. Valle

Biological Sciences Faculty Publications

During the 1960s and 1990s, the California Department of Fish and Game tagged 8,634 barred sand bass in southern California, and 972 fish (11%) were recaptured. Tag returns suggest barred sand bass are transient aggregate spawners that form spawning aggregations consisting of both resident and migrant individuals. Spawning residency at a historic spawning location was estimated by the frequency of returns over time; most same-year returns (82%, n  =  141) were recaptured within a 7 to 35-day period. The maximum recapture distance was 92 km. The average (± SD) non-spawning season recapture distance from peak spawning season tagging locations was …

Conservation Status And Habitat Use Of The West Virginia Spring Salamander (Gyrinophilus Subterraneus) And Spring Salamander (G. Porphyriticus) In General Davis Cave, Greenbrier Co., West Virginia, Matthew L. Niemiller, Michael S. Osbourn, Dante B. Fenolio, Thomas K. Pauley, Brian T. Miller, John R. Holsinger

Biological Sciences Faculty Publications

The West Virginia Spring Salamander (Gyrinophilus subterraneus) is one of four obligate cave-dwelling species of plethodontid salamanders found east of the Mississippi River in the United States. This species is endemic to a single cave system; General Davis Cave, in Greenbrier Co., West Virginia, where it is syntopic with the closely-related Spring Salamander (G. porphyriticus). Accordingly, the West Virginia Spring Salamander is a species of critical conservation concern. Because of it's conservation status and lack of data regarding the ecology and life history, particularly about population trends, we present data on relative abundance of and habitat …

The Impact Of Conservation On The Status Of The World's Vertebrates, Michael Hoffmann, Craig Hilton-Taylor, Ariadne Angulo, Monika Böhm, Thomas M. Brooks, Stuart H. M. Butchart, Kent E. Carpenter, Janice Chanson, Beth A. Polidoro, Jonnell C. Sanciangco

Biological Sciences Faculty Publications

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the …

Evaluation Of Green Tea Extract As A Glazing Material For Shrimp Frozen By Cryogenic And Air-Blast Freezing, Srijanani Sundararajan 2010 Louisiana State University and Agricultural and Mechanical College

Evaluation Of Green Tea Extract As A Glazing Material For Shrimp Frozen By Cryogenic And Air-Blast Freezing, Srijanani Sundararajan

LSU Master's Theses

Green tea (Camellia sinensis) extract (GTE) is rich in polyphenolic compounds, especially catechins that are potent antioxidants. The antioxidant property of GTE may make it ideal for use as a glazing solution for suppressing lipid oxidation in shrimp (Litopenaeus setiferus) during frozen storage. In this study, GTE was evaluated as a glazing material for shrimp frozen by air-blast (BF) and cryogenic freezing (CF). Two percent, three percent and/or five percent green tea extract solutions (2GTE, 3GTE, 5TGE) were used for glazing. Distilled water glazed (GDW) and non-glazed (NG) shrimp were used as controls. The GTE was characterized by measuring color, …

Quantifying Tarnished Plant Bug, Lygus Lineolaris (Palisot De Beauvois), Resistance To Acephate In Louisiana, Josh T. Copes

LSU Master's Theses

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is one of the most yield- limiting insect pests attacking cotton in the Mid-Southern region of the U.S. This pest is almost exclusively managed with chemical control strategies. The organophosphate insecticide, acephate, has been one of the most important insecticides recommended to control tarnished plant bugs. In recent years, reports of unsatisfactory acephate performance have become common and actual field rates have been increased to improve control. The objective of this study was to survey acephate susceptibility in Louisiana populations of tarnished plant bug using laboratory bioassays and evaluate acephate efficacy …

Burkholderia glumae is the bacterial pathogen causing bacterial panicle blight disease of rice (BPB). The pathogen, whose growth and pathogenicity is favored by high temperatures, has become a serious threat to rice production around the world possibly due to the current global climate changes. In this study, previously reported avirulent B. glumae strains were characterized in respect to the production of known virulence factors, toxoflavin, lipase and motility, and potential virulence factors, including polygalacturnase and type III secretion system (hypersensitive response). Considerable phenotypic variation was observed among the strains tested. Virulence of the B. glumae strains was closely related to …


Toxicity Interaction Of Fipronil And Imidacloprid Against Coptotermes Formasanus, Pan Luo 2010 Louisiana State University and Agricultural and Mechanical College

Toxicity Interaction Of Fipronil And Imidacloprid Against Coptotermes Formasanus, Pan Luo

LSU Master's Theses

The Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), is considered one of the most destructive structural pests in the world, especially in warm and humid areas. Insecticide application is an effective strategy in termite control. In recent years, non-repellent insecticides have become popular for their high efficacy due to delayed toxicity and horizontal transfer. Fipronil (registered name Termidor®) and imidacloprid (registered name Premise®) have been applied to the perimeter of millions of houses in the United States. Fipronil and imidacloprid have different modes of action which may produce a synergistic effect when combined. There have been no studies on …
