This book was released on 2003 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: O Brasil é, hoje, o maior produtor de feijão (Phaseolus vulgaris (L.) do mundo e os grãos representam amais importante fonte de proteína para a população, entretanto, a produtividade é uma das mais baixas conhecidas. Maiores produtividades a um baixo custo podem ser obtidos pelo melhoramento da eficiência da fixação biológica de N (FBN), mas as principais limitações são a susceptibilidade da simbiose aos estresses ambientais, como as altas temperaturas e o baixo teor de umidade de solo. O sistema de plantio direto (PD) reduz consideravelmente esses estresses e tem sido associado com maiores produtividades do feijoeiro da FBN, entretanto, os efeitos na diversidade de rizóbios ainda pouco conhecidos. Este estudo foi conduzido com o objetivo de avaliar a diversidade de rizóbios de áreas cultivadas com o feijoeiro dos estados do Paraná (PR) e Santa Catarina (SC) sob PD e plantio convencional (PC), bem como, em uma área de campo nativo de Sc manejado inadequadamente. A diversidade genética foi avaliada pela análise do DNA como o "primer" BOX A1R-PCR para detectar diferenças entre as estirpes, e por RFLP-PCR da região 16S rRNA, para diferenciar espécies. Em ambos os estados, maior diversidade de estirpes foi observada no sistema de PD, sendo que os perfis observados sob PD diferiram daqueles observados sob PC. Foram obtidos resultados semelhantes de diversidade genética de espécies em Campo Belo do Sul, SC, todavia, em Ponta Grossa, PR, menor número de perfis de RFLP-PCR da região 16S rRNA foi observado. É possível que as condições relacionadas ao PD em Ponta Grossa favoreçam a dominância de poucas espécies, mas com alta diversidade genética dentro das espécies. A ausência da planta hospedeira e o manejo inadequado do campo nativo reduziram drasticamente a diversidade de estirpes e de espécies. O feijoeiro é um hospedeiro promíscuo e a população associada com esta leguminosa é muito sensível às mudanças ambientais, desse modo o rizóbio poderia ser utilizado para monitorar os efeitos de práticas agrícolas. A grande diversidade de rizóbios observada, com detecção de 47 perfis de RFLP-PCR da região 16S rRNA, indica a necessidade de maiores estudos sobre a estrutura e dinâmica dessas populações.

Book Synopsis Strategies and Tools for a Sustainable Rural Rio de Janeiro by : Udo Nehren
Download or read book Strategies and Tools for a Sustainable Rural Rio de Janeiro written by Udo Nehren and published by Springer. This book was released on 2018-08-16 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of recent developments in land, ecosystem, and water management in the Brazilian state of Rio de Janeiro. The state is located in the biodiversity hotspot of the Atlantic Forest (Mata Atlântica), a biome characterized by high biological diversity and endemism. At the same time the state of Rio de Janeiro emerged to one of the economic hubs in Latin America. This development process has been accompanied by population growth, industrialization, urbanization, as well as consumption and degradation of land and water resources. In the past years many efforts have been made to stop or at least slow down these degradation processes and restore degraded environments with the overall goal to bring together sustainable management of natural resources, nature conservation, and economic development. An overview is provided of the different strategies and tools that have been developed in the fields of agriculture, ecosystem management and biodiversity, integrated water management, land restoration, disaster risk reduction and climate change adaptation, as well as environmental governance and economic instruments. This book covers a wide spectrum from applied research to science‐policy interfaces, planning concepts, and technical tools and has a model character for other rural areas in Latin America. Target groups are scientists, practitioners, policy makers and graduate students in the field of environmental management. The different chapters are written by researchers and practitioners of the German‐Brazilian project INTECRAL (Integrated Eco Technologies and Services for a Sustainable Rural Rio de Janeiro), the rural development program Rio Rural under the state secretary for agriculture and animal husbandry, as well as invited scientists from Brazilian universities and research institutes. It bridges existing gaps between science, policies, and practice in rural development.
Book Synopsis Presidents and Terminal Logic Behavior by : Genevieve M. Kehoe
Download or read book Presidents and Terminal Logic Behavior written by Genevieve M. Kehoe and published by Texas A&M University Press. This book was released on 2014-05-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presidents of nations with constitutionally imposed term limits are often viewed as growing weaker as they approach the end of their time in office. However, in this important new study, political scientist Genevieve M. Kehoe argues that because such chief executives are free from reelection constraint and often still enthusiastic to create a legacy by pursuing bold projects, they may accomplish significant initiatives. Kehoe has developed a concept for this which she calls “Terminal Logic Behavior” (TLB). Presidents and Terminal Logic Behavior: Term Limits and Executive Action in the United States, Brazil, and Argentina provides both case studies and quantitative evidence to show how US presidents of the last three decades have utilized decrees on foreign, domestic, and environment policy during their final months in office. She finds a systematic pattern of decree use consistent with the mark of TLB in a most unexpected place—presidents’ use of national emergency powers. In a careful comparative analysis, she also finds support for her argument in the Argentinean and Brazilian experience of the same period.

This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past half century, filamentous fungi have grown in commercial importance not only in the food industry but also as sources of pharmaceutical agents for the treatment of infectious and metabolic diseases and of specialty proteins and enzymes used to process foods, fortify detergents, and perform biotransformations. The commercial impact of molds is also measured on a negative scale since some of these organisms are significant as pathogens of crop plants, agents of food spoilage, and sources of toxic and carcinogenic compounds. Recent advances in the molecular genetics of filamentous fungi are finding increased application in the pharmaceutical, agricultural, and enzyme industries, and this trend promises to continue as the genomics of fungi is explored and new techniques to speed genetic manipulation become available. This volume focuses on the filamentous fungi and highlights the advances of the past decade, both in methodology and in the understanding of genomic organization and regulation of gene and pathway expression.
