G03-1526 Prevention And Control Of Rabbit Damage, Dallas R. Virchow, Scott E. Hygnstrom, Dennis M. Ferraro Jan 2003

G03-1526 Prevention And Control Of Rabbit Damage, Dallas R. Virchow, Scott E. Hygnstrom, Dennis M. Ferraro

University of Nebraska-Lincoln Extension: Historical Materials

Cottontail rabbits (Sylvilagus spp.) and jackrabbits (Lepus spp.) are found in most of Nebraska. The eastern cottontail (S. floridanus) lives throughout the state while the desert cottontail (S. audubonii) lives only in western Nebraska. Black-tailed (L. californicus) and white-tailed jackrabbits (L. townsendii) are most common in the western two-thirds of Nebraska.

This NebGuides describes how to identify rabbit damage and recommends proper methods of control, such as fencing, habitat modification, repellents, trapping, and shooting to reduce damage to tolerable levels.

Nf03-571 Aspergillus Flavus And Aflatoxins In Corn, Jim Stack, Michael Carlson Jan 2003

Nf03-571 Aspergillus Flavus And Aflatoxins In Corn, Jim Stack, Michael Carlson

University of Nebraska-Lincoln Extension: Historical Materials

The severe weather conditions of the 2002 growing season resulted in an increase in the incidence and severity of aflatoxin contamination of both food grade and feed grade corn in Nebraska.

The mycotoxin called aflatoxin is produced by the grain mold Aspergillus flavus. Not all isolates of A. flavus produced aflatoxin and isolates that are capable of producing aflatoxin do not always synthesize the toxin. Many factors including environmental conditions and host suscepbitility, determine the incidence and severity of grain mold and subsequent mycotoxin contamination.

This NebFact discusses the cause and occurrence of aflatoxin in corn; the effects it has …


Nf03-570 Fumonisins In Corn, Jim Stack, Michael Carlson Jan 2003

Nf03-570 Fumonisins In Corn, Jim Stack, Michael Carlson

University of Nebraska-Lincoln Extension: Historical Materials

During the past two years, millers have rejected some Nebraska food grade corn because it was contaminated with the mycotoxin fumonisin. Most of the contaminated samples and the highest levels of contamination were detected in corn from counties in the eastern half of Nebraska.

Fumonisins are mycotoxins produced by the grain molds Fusarium verticillioides and Fusarium proliferatum. These fungi are commonly found in corn throughout the United States.

This NebFact discusses the cause and occurrence of fumonisin in corn; the effects it has on plants, animals and humans; and management options to minimize fumonisin contamination.

G1512 Establishing Conservation Plantings Of Nut Trees And Shrubs By Direct Seeding Methods, Steven D. Rasmussen, Scott J. Josiah, Jon Wilson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to plant and raise nut trees and shrubs from seed. Seeding methods, planting design, site preparation and post-planting care are discussed.

Introduction

Conservation tree and shrub plantings create wildlife habitat, improve water quality, produce marketable nuts, and enhance landscape diversity. Usually, nursery-grown seedlings are used to establish these plantings. However, a number of problems exist when using seedlings, including increased costs and reduced initial tree vigor and survival. Direct seeding of tree and shrub seeds avoids many of these problems, and is a proven, effective means to establish conservation plantings in Nebraska and elsewhere.

Strategies For Range Beef Cattle Producers In Arid Environments Following Drought, Tom Holman, David Baltensperger, Pat Reece, Ivan Rush Jan 2003

Strategies For Range Beef Cattle Producers In Arid Environments Following Drought, Tom Holman, David Baltensperger, Pat Reece, Ivan Rush

University of Nebraska-Lincoln Extension: Historical Materials

Precipitation can be below average for much of the Nebraska Panhandle and adjoining areas for prolonged periods. Prolonged drought results in an inadequate supply of forage for hundreds of thousands of beef cattle on millions of acres of rangeland. While some variation occurs among ranches and among pastures within a given ranch, all rangeland vegetation in arid environments like western Nebraska can be moderately to severely damaged by drought stress and/or excessive grazing. Consequently, even if soil moisture is not limited in the years following a drought, spring growth rate will be reduced and total annual forage production can be …

The Role Of Eicosanoids On Nodulation Reactions To Bacterium Serratia Marcescens In Larvae Of Ostrinia Nubilalis, Hasan Tunaz, Ali̇ Arda Işikber, Mehmet Kubi̇lay Er Jan 2003

The Role Of Eicosanoids On Nodulation Reactions To Bacterium Serratia Marcescens In Larvae Of Ostrinia Nubilalis, Hasan Tunaz, Ali̇ Arda Işikber, Mehmet Kubi̇lay Er

Turkish Journal of Agriculture and Forestry

Nodulation is the first step of the cellular defense reactions to bacterial infections in insects. In the present study, injecting larvae of the European corn borer, Ostrinia nubilalis, with eicosanoid biosynthesis inhibitors, immediately prior to intrahemocoelic injections of the bacterium, Serratia marcescens, sharply reduced the nodulation response to bacterial challenges. Separate treatments with specific inhibitors including dexamethasone (a phospholipase A_2 inhibitor), indomethacin (a cyclooxygenase inhibitor) and phenidone (a dual cyclooxgenase/lipoxygenase inhibitor) also impaired the ability of European corn borers to form nodules in reaction to bacterial challenges. The inhibitory influence of phenidone was apparent within 30 mins after infection, and …

Addressing Off-Site Nutrient Pollution Through Conventional Management Actions: A Modelling Case Study, David Weaver, Simon Neville, David Deeley Jan 2003

Addressing Off-Site Nutrient Pollution Through Conventional Management Actions: A Modelling Case Study, David Weaver, Simon Neville, David Deeley

Conference papers and presentations

The ecology of estuaries on the south coast of Western Australia has been disrupted by increased nutrient and sediment discharge from predominantly rural catchments. Seagrass beds have been replaced by macroalgae, and toxic algal blooms threaten human and animal health, and reduce amenity. A range of conventional management actions are available to reduce nutrient loss at source, and it is important to evaluate possible reductions, and costs, so that limited funds can be targeted to realise the greatest moderation of nutrient loss. A lumped landuse nutrient generation rate model was developed for four catchments (Wilson Inlet, Oyster Harbour, Torbay Inlet …
