Farmers And Nature Conservation: What Is Known About Attitudes, Context Factors And Actions Affecting Conservation?, Johan Ahnström, Jenny Höckert, Hanna L. Bergea, Charles A. Francis, Peter Skelton, Lars Hallgren

Department of Agronomy and Horticulture: Faculty Publications

Farmers’ attitudes towards viability of specific conservation practices or actions strongly impact their decisions on adoption and change. This review of ‘attitude’ information reveals a wide range of perceptions about what conservation means and what the impacts of adoption will mean in economic and environmental terms. Farmers operate in a tight financial situation, and in parts of the world they are highly dependent on government subsidies, and cannot afford to risk losing that support. Use of conservation practices is most effective when these are understood in the context of the individual farm, and decisions are rooted in land and resource …

Department of Agronomy and Horticulture: Faculty Publications

Background: A large number of genetic variations have been identified in rice. Such variations must in many cases control phenotypic differences in abiotic stress tolerance and other traits. A single feature polymorphism (SFP) is an oligonucleotide array-based polymorphism which can be used for identification of SNPs or insertion/deletions (INDELs) for high throughput genotyping and high density mapping. Here we applied SFP markers to a lingering question about the source of salt tolerance in a particular rice recombinant inbred line (RIL) derived from a salt tolerant and salt sensitive parent. Results: Expression data obtained by hybridizing RNA to an oligonucleotide array …


The Association Between Alcohol Sales And County Level Economic Growth In Kentucky, Julia Hinkle Rollins Jan 2009

The Association Between Alcohol Sales And County Level Economic Growth In Kentucky, Julia Hinkle Rollins

University of Kentucky Master's Theses

This thesis evaluates the effectiveness of using alcohol sales as an indicator of development or lag associated with development in Kentucky counties using summary statistics, shift-share analysis and an econometric model. The summary statistics are used to evaluate possible lines of causality and the Shift-share analysis and econometric model deal the specific characteristics of the county that are assumed to be influenced by the sale of alcohol. Limitations to the county level data were limiting to the time period evaluated in this thesis. As a result, much of the findings were inconclusive as to the relationship between county level economic …

Department of Agronomy and Horticulture: Faculty Publications

Introduction

Antibiotic1 use in animal production has led to improved feed use efficiency and increased growth rates. In turn, these resulted in reduced food production costs and reduced excrement of manure nutrients which may cause pollution problems.

On the other hand, antibiotic use leads to antibiotic resistance and a possible reduction in effectiveness of treatment options for both animals and humans. This publication addresses these issues.

Disease-causing microorganisms2, including bacteria,are the most diverse and numerous organisms on earth. Diverse in their habitat, environmental adaptation, and mechanisms of reproduction, they have short generations with high multiplication rates. Such characteristics help develop …

Woods Of A Miocene Petrified Forest Near Ankara, Turkey, Ünal Akkemi̇k, Necla Türkoğlu, Imogen Poole, İhsan Çi̇çek, Nesi̇be Köse, Gürcan Gürgen

Turkish Journal of Agriculture and Forestry

The taxonomic composition of a recently discovered silicified fossil forest, preserved by volcanic activity 18.2-16.9 million years ago in Çamlıdere near Ankara (Turkey), is investigated. Many samples collected were divided into 2 groups as CAM1 and CAM2. Thin sections from transversal, radial, and tangential directions were cut to identify the woods. Wood identifications were performed using standard techniques and fossil wood features. The preserved wood indicates that the forest was composed almost exclusively of Taxodium (CAM1) and Sequoia (CAM2). These genera were extinct from Anatolia and Europe during late Miocene.
